     Description of the Related Art 
     The following background is provided as an aid in understanding the invention and is not admitted to describe or constitute prior art to the invention. 
     The K ATP  channel is an octomeric ion channel consisting of 4 copies of the sulfonyl urea receptor (SURx) and 4 copies of an inwardly rectifying ion channel (Kir6.x). K ATP  channels are widely distributed and present in a number of tissues including, but not limited to cardiac, cardiovascular smooth muscle, skeletal muscle, adipocytes, pancreas, and various CNS tissues. Their activity is primarily regulated by adenine nucleotides, characteristically being activated by falling ATP and rising ADP levels. Thus, they link cellular metabolism with membrane excitability. The K ATP  channel exists in several different isotypes or subspecies defined by the specific version of SURx receptor and Kir6.x that comprise the channel. The channel that is typically present in cardiac tissue include the SUR2a receptor, cardiovascular smooth muscle includes the SUR2b receptor while SUR1 containing channels are found in the brain, pancreas, and adipocytes. In skeletal muscle, both SUR2b and SUR1 isotypes of the channel have been identified. In most excitatory cells the K ATP  channel is closed under normal physiological conditions and open when the tissue is metabolically compromised, as characterized by falling ATP levels. This promotes K+ efflux and cell hyperpolarization, thereby preventing voltage operated Ca2+ channels (VOCs) from opening. Activation of the K ATP  channel in cardiovascular smooth muscle has been shown to result in vasodilation. Activation of the channel has been shown to be protective of tissues under ischemia reperfusion stress. Maintenance of K ATP  channel potassium current can limit the extent of atrophy under various stress conditions. In addition to the isotypes of the channel that exist in the cell membrane, the K ATP  channel also is present in the mitochondrial inner membrane. Some the cardioprotective effects of agonizing the K ATP  channel are attributable to agonizing the mitochondrial isotype of the channel as are some of the benefits realized in animal models of Alzheimer&#39;s disease. Diazoxide, nicorandil, pinacidil and minoxidil are examples of K ATP  channel openers. 
     Nitric oxide donors may release NO by its spontaneous donation, by enzymatic oxidation or by chemical reaction. Nitric oxide donors, like nitroglycerin, have a principal pharmacological action of relaxation of vascular smooth muscle. Although venous effects predominate. NO donors produce, in a dose-related manner, dilation of both arterial and venous beds. This serves to regulate blood pressure, reduce stress on failing hearts and increase blood flow to the heart. NO has a variety of functions such as the release of prostanoids, inhibition of platelet aggregation, effect on angiogenesis, and production of oxygen free radicals. In addition to nitroglycerin, isosorbide mononitrate, nicorandil, glyceryl trinitrate and sodium nitroprusside are examples of NO donors. 
     Angiotensin converting enzyme inhibitors limit the conversion of angiotensin I to angiotensin II preventing the vasoconstricting effect of angiotensin II resulting in vasodilation and a reduction in blood pressure. ACE inhibitors are used in the management of hypertension, to manage progression of congestive heart failure and left ventricular dysfunction and to reduce cardiovascular death and morbidity in individuals who have suffered a myocardial infarction. Examples of ACE inhibitors include benzepril, captopril, enalopril, lisinopril, zofenopril and ramipril. 
     Hydrogen sulfide (H 2 S) is a cytoprotective physiological signaling molecule that acts in concert with NO and carbon monoxide (CO) to maintain physiological homeostasis in both the heart and circulation. H 2 S is produced in mammalian tissue by 3 tissue specific enzymes: cystathionine c-lyase (CSE), cystathionine b-synthase (CBS), and 3-mercaptopyruvate sulfur transferase (3-MST). Recent experimental evidence has shown that H 2 S is a potent cardioprotective signaling molecule, and the administration of H 2 S releasing agents or donors significantly attenuates the pathological consequences of myocardial ischemia/reperfusion injury (I/R) and heart failure. Examples of H 2 S releasing agents include sulfide salts, Lawesson&#39;s reagent/analogs, 1,2-dithiole-3-thiones, and zofenopril. 
     Beta-blockers are competitive antagonists that block the receptor sites for endogenous catecholamines epinephrine and norepinephrine on beta-adrenergic receptors, and thereby reduce the effect of epinephrine on cardiovascular smooth muscle and cardiac tissue, lowering blood pressure and reducing heart rate, and the heart&#39;s demand for oxygen. There are 3 types of beta-adrenergic receptors, betas located mainly in the heart and kidneys, beta2 located mainly in the lungs, gastrointestinal tract, liver, uterus, vascular smooth muscle, and skeletal muscle, and beta3 located in fat cells. 
     Nicorandil is a nicotinamide nitrate used as an antianginal agent. It is unique among therapeutics used in the treatment of ischemia in that it has two modes of action. First, by agonizing K ATP  channels, nicorandil increases transmembrane potassium conductance and relaxes peripheral and coronary arterioles. Nicorandil is capable of agonizing the mitochondrial form of the K ATP  channel. In doing so, it exerts a tissue protective effect in the context of cellular stress from various causes. Second, with its nitrate moiety, functioning as an NO donor, nicorandil increases intracellular concentrations of cGMP, resulting in peripheral vein and coronary artery dilation. Thus, because of its ability to dilate arteries and veins, nicorandil maximizes coronary flow while concomitantly reducing myocardial work through reductions in afterload. For these reasons, nicorandil has been successful in managing angina pectoris. The K ATP  channel activation of nicorandil has broad ranging effects, some of which are attributable to its activation of the mitochondrial K ATP  channel. Oral formulations of nicorandil have been approved in various countries and regions to treat stable angina pectoris. Intravenous formulations have also been approved in some regions and used during percutaneous coronary intervention (PCI).

     DETAILED DESCRIPTION 
     Various embodiments provide pharmaceutical coformulations comprising a nitrogen oxide (NO) donor and a hydrogen sulfide (H 2 S) releasing agent, and methods of using them to treat a variety of diseases and/or conditions as described elsewhere herein, including for example CKD, Duchenne Muscular Dystrophy, Becker Muscular Dystrophy, familial dilated cardiomyopathy and idiopathic dilated cardiomyopathy. 
     Surprisingly, pharmaceutical coformulations have now been developed in which the H 2 S releasing agent is present in the coformulation an amount that is effective to enhance the therapeutic efficacy of the NO donor. In various embodiments the effects of coadministering the NO donor and H 2 S releasing agent are synergistic. This invention is not limited by theory of operation and the mechanism by which the H 2 S releasing agent enhances the therapeutic efficacy of the NO donor is not completely understood. However, a possible mechanism is described herein for the benefit of those skilled in the art. Pharmacologically, nicorandil acts as both a KATP channel opener and a nitrate or NO donor. It is capable of agonizing both the cell membrane and mitochondrial forms of the KATP channel. 
     Zofenopril is a sulfhydryl containing ACE inhibitor that is also a H2S releasing agent. In studies in mice, zofenopril acts as a H 2 S releasing agent directly elevating plasma and myocardial tissue H 2 S levels compared to vehicle treated animals. The early H 2 S increase following zofenopril administration appears to be due to direct release by zofenopril, which has also been shown to slowly release H 2 S into solution in a cell-free assay. H 2 S is generated in tissues through the action of either cystathionine β-synthase (CBS) or cystathionine γ-lyase (CSE) acting on L-cysteine as a substrate. Zofenopril treatment appears to increase CSE expression and thus upregulates endogenous H2S generation as well. Ramipril, an ACE inhibitor lacking the sulfhydryl group did not elevate plasma or myocardial tissue H 2 S levels in the same model. 
     Zofenopril may potentiate one or more activities of nicorandil. Zofenopril administration in mice significantly increased both plasma and myocardial tissue NO 2  levels compared with vehicle treated animals, and there was a trend towards increasing the activation of endothelial nitric oxide synthase (eNOS) as measured by increased phosphorylation of eNOS 1177 . ACE inhibition may directly increase NO 2  bioavailability by a bradykinin mediated pathway. In the same mouse study, ramipril had virtually no effect on plasma or myocardial tissue NO 2  concentrations. This indicates that the increased NO 2  bioavailability of zofenopril is associated with its H 2 S releasing activity rather than ACE inhibition. Other H 2 S releasing agents appear to increase eNOS expression or activity as well. 
     Thus, coadministration of zofenopril and nicorandil may increase NO 2  bioavailability beyond that achieved by nicorandil alone or by the coadministration of nicorandil with any other ACE inhibitor, improving any NO 2  mediated therapeutic response. 
     Several of the effects of H 2 S appear to be mediated by KATP channel activation. KATP channel current can be measured directly as can the resulting cell membrane hyperpolarization. Exposure of rat aortic SMCs to H 2 S results in a significantly increased amplitude of KATP channel current. This excitory effect of H 2 S was fully manifested 3 minutes after application of H 2 S and nullified immediately after washing H 2 S from the bath solution. This suggests it is a direct effect of the application of H 2 S. Similarly, the cell membrane was rapidly hyperpolarized after application of H 2 S and was reversed 3-5 minutes after the application of glibenclamide, a KATP channel agonist. 
     The expression of the components of the KATP channel (SUR2b and Kir6.1) are downregulated in cardiovascular smooth muscle of spontaneously hypertensive rats. In this context, administration of H 2 S increased vascular expression of SUR2b and Kir6.1. Thus, over longer-term administration, H 2 S may increase KATP mediated responses by increased expression of the KATP channel subunits. 
     Intravenous injection of H 2 S provokes a transient but significant decrease in mean arterial blood pressure. The H 2 S-induced decrease in blood pressure was antagonized by glibenclamide a KATP channel antagonist. 
     High glucose has been shown to impair KATP channels in human vascular smooth muscle cells. High glucose exposure of H9c2 cardiac cells results in cytotoxicity, apoptosis, oxidative stress and mitochondrial damage. These effects were ameliorated by treatment with a H 2 S donor (NaHS), or either of two KATP channel agonists, diazoxide and pinacidil. Pretreatment of these cells with either a mitochondrial KATP channel antagonist (5-HD) or glibenclamide prior to NaHS treatment significantly diminished the cardioprotective effects, suggesting they are mediated by KATP channel activation. 
     In Langendorff-perfused rat hearts subjected to ischemia/reperfusion, the use of a H 2 S releasing agent (4-carboxypheny isothiocyanate) significantly improved the post-ischemic recovery of myocardial functional parameters, limited tissue injury and reduced the post-ischemic release of norepinephrine and the incidence of ventricular arrhythmias. These effects were antagonized by 5-HD. 
     In perfused rat atria, NaHS, a H 2 S donor, increased atrial natriuretic peptide (ANP) secretion and decreased atria pressure in a dose dependent manner, which was blocked by pretreatment with a KATP channel antagonist. 
     In isolated rat hearts, zofenopril had little effect on pre-ischemic coronary flow or on contractile function. Zofenopril significantly improved reperfusion function. This protective effect was complete reversed by both KATP channel antagonists, glyburide and 5-HD. Reperfusion end diastolic pressure (EDP) and lactate dehydrogenase (LDH) release were also significantly reduced and these protective effects were completely reversed by glyburide and 5-HD. Time to contracture (TTC) during global ischemia was used to evaluate the cardioprotective effective of chromakalim, and zofenopril. The effect of the drugs was tested individually and in combination in 3 ratios. The maximum increase in TTC was significantly higher in the hearts treated with the combination vs. those treated with either drug alone. Comparing the response for each of the 3 combinations relative to the theoretical line of additivity on an isobologram indicates that the two compounds interact to give a super-additive response. Chromakalim was able to induce a near maximal relaxation of aortic rings, while the maximal response to zofenopril was only 89%. Both glyburide and 5-HD shifted the relaxation response curve of zofenopril to the right suggesting that the relaxation was KATP channel mediated. Super-additivity was also observed for the combination of zofenopril and chromakalim on aortic ring relaxation. Competition studies with glyburide show that it is a competitive antagonist of chromakalim, but a non-competitive antagonist of zofenopril, consistent with chromakalim being a direct KATP channel agonist while the activity of zofenopril on the channel is mediated indirectly via H 2 S. 
     Accordingly, it appears that an H 2 S releasing agent may enhance the therapeutic efficacy of an NO donor by potentiating both NO 2  mediated therapeutic responses to the NO donor and the KATP channel mediated responses to the NO donor, with the potential for synergistic super-additivity. For example, coadministration of nicorandil with zofenopril may improve therapeutic responses to nicorandil without increasing the frequency or severity of adverse events which are primarily associated with metabolites of nicorandil rather than its direct pharmacological action or off target effects and to provide effective ACE inhibition and the therapeutic benefits that it contributes in treated patients. 
     Provided herein are pharmaceutical coformulations of K ATP  channel activators with NO donors, ACE inhibitors and H 2 S releasing agents and their use in the treatment of end stage renal disease patients treated with hemo- or peritoneal dialysis or following a kidney transplant.

     Also provided are pharmaceutical formulations of the salt including extended release formulations. Also provided are coformulations of the salt with nicorandil. In one coformulation the ratio of nicorandil to the salt is about 1:10. In other coformulations the ratio of nicorandil to the salt is in the range of about 1:9 to about 1:5. In other coformulations the ratio of nicorandil to the salt is in the range of about 1:5 to 1:2. In another coformulation the ratio of nicorandil to the salt is the range of about 1:2 to about 1:1. In other coformulations the ratio of nicorandil to the salt is about 1.1:1 to about 2.9:1. In another coformulation the ratio of nicorandil to the salt is 3:1 to about 5:1. 
     Provided are methods of improving the solubility of a salt or cocrystal of zofenopril prior to its coformulation with nicorandil by one of the following techniques: (a) particle size reduction involving comminution, spray drying, or other micronising techniques, (b) use of an ion exchange resin, (c) use of inclusion complexes, for example cyclodextrin, (d) compaction with a solubilizing agent including a low viscosity hypromellose, low viscosity methylcellulose or similarly functioning excipient or combinations thereof, (e) association with a salt prior to formulation, (f) use of a solid dispersion, (g) use of a self-emulsifying system, (h) addition of one or more surfactants to the formulation, (i) use of nanoparticles, or (j) combinations of these approaches. 
     Further provided herein are controlled release pharmaceutical coformulations containing a NO donor, a K ATP  channel agonist, an ACE inhibitor and a hydrogen sulfide releasing pharmaceutical active ingredient, which include at least one component that substantially inhibits release of the pharmaceutical active ingredients from the formulation until after gastric transit is complete. As used herein, “substantially inhibits” means less than 20% release, more preferably at least less than 10% release, or even more preferably at least less than 5% release of the drug from the formulation during gastric transport. Release can be measured in a standard USP based in-vitro gastric dissolution assay in a calibrated dissolution apparatus. See e.g., U.S. Pharmacopeia, Chapter 711 (2016).

     As used herein, an erodable matrix is the core of a tablet formulation that, upon exposure to a suitable aqueous environment, begins a process of disintegration which facilitates the release of drug from the matrix. The rate of release of drug from the tablet is controlled both by the solubility of the drug and the rate of disintegration of the matrix. 
     Also provided herein are extended release pharmaceutical coformulations containing a NO donor, a K ATP  channel agonist, an ACE inhibitor and a hydrogen sulfide releasing pharmaceutical active ingredient, wherein the formulation includes a hydrogel which provides stability for the tablet matrix over time, controls the rate of release from the hydrated tablet matrix, are bioadhesive and gastro-retentive.

     Acute myocardial infarction: myocardial infarction occurs when myocardial ischemia, a diminished blood supply to the heart, exceeds a critical threshold and overwhelms myocardial cellular repair mechanisms designed to maintain normal operating function and homeostasis. Ischemia at this critical threshold level for an extended period results in irreversible myocardial cell damage or death. 
     Adolescent: A person between 10 and 18 years of age. 
     Agonist: A chemical compound that has affinity for and stimulates physiological activity at cell receptors normally stimulated by naturally occurring substances, triggering a biochemical response. An agonist of a receptor can also be considered an activator of the receptor.

Dysfunctional mitochondria likely lead to other signs and symptoms of Barth syndrome. 
     Becker muscular dystrophy: is an inherited condition that causes progressive weakness and wasting of the skeletal and cardiac muscles. It primarily affects males. The age of onset and rate of progression can vary, Muscle weakness usually becomes apparent between the ages of 5 and 15. In some cases, cardiomyopathy is the first sign. BMD is caused by a mutation in the DMD gene and is inherited in an X-linked recessive manner. BMD is very similar to Duchenne muscular dystrophy, except that in BMD, symptoms begin later and progress at a slower rate.

     Duchenne muscular dystrophy: is a severe type of muscular dystrophy. The symptom of muscle weakness usually begins around the age of four in boys and worsens quickly. Typically, muscle loss occurs first in the upper legs and pelvis followed by those of the upper arms. This can result in trouble standing up. Most are unable to walk by the age of 12. Affected muscles may look larger due to increased fat content. Scoliosis is also common. Some may have intellectual disability. Females with a single copy of the defective gene may show mild symptoms. The disorder is X-linked recessive. It is caused by a mutation in the DMD gene which encodes the dystrophin protein. DMD affects about one in 5,000 males at birth. 
     Dystrophin: is a large rod-shaped cytoplasmic protein including 3685 amino acid residues. In skeletal and cardiac muscle, dystrophin associates with various proteins to form the dystrophin-associated protein complex (DAPC).

     Idiopathic dilated cardiomyopathy: dilated cardiomyopathy (DCM) is characterized by dilatation and systolic dysfunction of one or both ventricles. DCM is classified as idiopathic (idiopathic dilated cardiomyopathy, or IDC) when all usual clinically detectable, except genetic, causes have been excluded. 
     Inflammation: is part of the complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants, and is a protective response involving immune cells, blood vessels, and molecular mediators.

     In a fourth example a coformulation of nicorandil or a pharmaceutically acceptable salt thereof and a salt or cocrystal of zofenopril is produced with the following composition: 25% w/w nicorandil, 25% of a salt or cocrystal of zofenopril, 30% polyethylene oxide (WSR-303), 17.9% microcrystalline cellulose and 1.2% fumed silica and 0.9% magnesium stearate. The materials are blended until uniform and then compressed into a tablet. The formulation can be compressed into tablets with a uncoated core tablet weight of either about 32 mg which contains 8 mg of nicorandil and 8 mg of a salt or cocrystal of zofenopril, 64 mg which contains 16 mg of nicorandil and 16 mg of a salt or cocrystal of zofenopril, or 128 mg which contains 32 mg of nicorandil and 32 mg of a salt or cocrystal of zofenopril. These core tablets are then coated with a non-functional coating, the color of which depends on the tablet weight. 
     In a fifth example a formulation of a 1:2 stoichiometry cocrystal of zofenopril and nicorandil is produced with the following composition: 50% w/w of the cocrystal, 30% polyethylene oxide (WSR-303), 17.9% microcrystalline cellulose and 1.2% fumed silica and 0.9% magnesium stearate. The materials are blended until uniform and then compressed into a tablet. The formulation can be compressed into tablets with an uncoated core tablet weight of either about 32 mg which contains 16 mg of the cocrystal, 64 mg which contains 32 mg of the cocrystal, or 128 mg which contains 64 mg of the cocrystal. These core tablets are then coated with a non-functional coating, the color of which depends on the tablet weight. 
     In another example, a cocrystal of nicorandil and zofenopril is formed by dissolving zofenopril in methanol that has been heated to 50° C. to the limits of its solubility and then dissolving an 2× or 4× excess of nicorandil in the heated saturated solution. The mixture is stirred for a period of about 6 hours and then cooled to 0-10° C. to drive the formation of the cocrystal.

     Examples 
     Synthesis and Characterization of Zofenopril Calcium Chloride 
     Zofenopril calcium was slurried in ACN. Two molar equivalents of HCl were added. The materials were allowed to slurry overnight. This resulted in a limited amount of white fine crystals which could be collected on 0.2 μm filter paper and dried under N 2 . The resulting crystals were shown to be zofenopril calcium chloride form A and designated sample 7535-40-02. The indexed XRPD pattern for the material is shown in  FIGS. 1 a    and  1   b.    1 H NMR (DMSO-d 6 ) results were obtained for zofenopril calcium chloride form A sample 7537-40-02 and shown to be consistent with zofenopril with trace amounts of nicorandil and ACN ( FIG. 2 ). DSC for zofenopril calcium chloride is shown as  FIG. 3 . On DSC this material has an onset at 162° C. This is in contrast to DSC results for zofenopril calcium which has an onset of 250.3° C. TGA results for zofenopril calcium chloride are provided in  FIG. 4 , there is 1.4% weight loss from 38 to 109° C. and 4.2% weight loss from 110 to 203° C. Based on IC, the calcium to zofenopril ratio is 0.99 to 1, and the chloride to zofenopril ratio is 0.89 to 1, which are consistent with 1:1:1 zofenopril calcium chloride. Hygroscopicity of zofenopril calcium chloride was evaluated by dynamic vapor sorption (DVS) and shown in  FIGS. 5 a  and 5 b   . DVS analysis indicates that Zofenopril Calcium Chloride Form A exhibits limited hygroscopicity at or below 65% RH; however, the material may deliquesce if exposed to relative humidity conditions above 65% RH. On the sorption step up to 65% RH, the material gained 1.2% weight. Above this RH, the material gained an additional 36.9% weight. It should be noted that equilibration timed out at all steps above 65% RH, indicating that the material may pick up more moisture than what was measured if it was allowed a longer equilibration time. Most of the weight was lost on desorption with significant hysteresis. The material recovered after the DVS experiment was identified as Zofenopril Calcium Chloride Form A by XRPD ( FIG. 6 ). Zofenopril calcium chloride form A exhibits limited aqueous solubility of approximately 0.1 mg/ml based on a gravimetric estimation. 
     Zofenopril calcium chloride form A, typically in admixture with other materials, was also obtained from a series of reactions involving one molar equivalent of zofenopril calcium with one or two molar equivalents of nicorandil which were combined in ACN followed by the addition of one or two molar equivalents of HCl. The results were slurried at least 8 hours, but also for as long as 3 days. The results were filtered and dried under N 2 . These reactions gave rise either to zofenopril calcium chloride form A or a combination of zofenopril calcium form A with zofenopril calcium form B. XRPD results for a reaction involving one molar equivalents of zofenopril calcium, nicorandil and HCl with the reaction slurried overnight before filtering giving rise to sample 7537-39-01 are shown in  FIG. 7 . XRPD results of a reaction involving one molar equivalent of zofenopril calcium, two molar equivalents of nicorandil and two molar equivalents of HCl and slurried for 3 days giving rise to sample 7615-27-04 are shown in  FIG. 8 . Zofenopril calcium chloride form A was also obtained as an admixture with CaCl 2 *6(H 2 O). This resulted from the reaction of zofenopril calcium in EtOAc with 2 molar equivalents of HCl. The reactants were slurried under ambient conditions for 3 days and then filtered and dried under N 2  resulting in sample 7537-61-02. The XRPD results for this sample are shown in  FIG. 9 . 
     Similarly, zofenopril calcium form A was obtained from the reaction of zofenopril calcium, dissolved in ACN and reacted with 2 molar equivalents of HCl. The reactants were slurried overnight and then filtered and dried under N 2  yielding sample 7537-55-01. The XRPD results for this sample are provided as  FIG. 10 . 
     Synthesis and Characterization of Zofenopril Sodium 
     Zofenopril calcium was slurried in water. One molar equivalent of H 2 SO 4  was added stepwise at which point the material clumped and then broke as a flocculent. The resulting material was extracted with DCM. The resulting materials formed an oil which was washed with water. The resulting oil was warmed to 40° C. and dried over MgSO 4 . The oil miscibilized upon warming. The resulting dried oil was placed under vacuum to remove any further solvent. 
     This oil, which is zofenopril free acid, was dissolved in ACN. NaOH in water was added to the dissolved zofenopril free acid solution. This resulted in the formation of a gel and a few white clumps. Additional water was added to the mixture at which point the gel broke and dissolved and a precipitate dropped out of solution. Additional ACN was added to this material and the resulting material was filtered and then rinsed with additional ACN resulting in a wet paste which was dried under N 2  yielding a free flowing powder designated zofenopril sodium material A (sample 7537-83-01). XRPD results for zofenopril sodium material A are provided in  FIG. 11 . The solubility of zofenopril sodium material A was tested and shown to be &gt;48 mg/ml. The pH of the solution at the end of the solubility was shown to be 10. The hygroscopicity of zofenopril sodium material A was tested using DVS. The results of that test are provided in  FIGS. 12 a  and 12 b   . The sample recovered following the DVS evaluation of zofenopril sodium material A was tested and shown to have a distinct XRPD profile to that of zofenopril sodium material A and was designed zofenopril sodium material B ( FIG. 13  sample 7578-51-01). The XRPD profiles of zofenopril sodium material A and material B are distinct from that of zofenopril hemisodium ( FIG. 14 ). 
     Synthesis and Characterization of Nicorandil Material B 
     Nicorandil was suspended in zofenopril, which is an oil at ambient temperatures. Heptane was added resulting in the formation of solids. Acetone was added drop-wise leading to reduction of the solids. The solids were triturated at ambient temperature giving rise to a crystalline solid which is a previously unreported form of nicorandil and designated nicorandil material B. The XRPD pattern from nicorandil material B was successfully indexed, indicating it is composed of a single crystalline phase ( FIGS. 15 a  and 15 b   ). It has an orthorhombic unit cell containing four molecules of nicorandil with a formula unit volume of 251.5 Å 3  consistent with an anhydrous form. 
     Synthesis and Characterization of Nicorandil HCl 
     Nicorandil free base was dissolved in acetone resulting in a clear solution. A molar equivalent of HCl was added stepwise following which there nucleation with rosettes of aciculars and blades that were birefringent. The resulting material was recovered and shown to be nicorandil HCl form A. The XRPD pattern for this sample is shown in  FIG. 16 . Based on the single crystal structure, nicorandil hydrochloride form A is anhydrous and contains one nicorandil cation and one chloride anion in the asymmetric unit. DVS was conducted with the sample and the results are shown in  FIGS. 17 a  and 17 b   . On the sorption step up to 75% RH, the material gained 0.5% weight. Above that it gained an additional 52% weight. Most of the weight was lost on desorption with significant hysteresis. The material recovered from DVS was shown by XRPD to be form A ( FIG. 18 ). Solubility of nicorandil HCl form A was tested and shown to be &gt;48 mg/mL which was the limit of the test. 
     In-Vitro Study of Rat Portal Vein Ring Relaxation with Zofenopril and Nicorandil 
     The portal vein was recovered from Wistar rats weighing approximately 450 gm, and divided into vein segments. Segments were placed in a bath containing approximately 10 mL of Krebs buffer at pH ˜7.4. The vehicle used for treatment was 0.2% DMSO. Portal vein rings were pre-contracted and incubated for 60 min at 32° C. Ring relaxation was measured after 10 minutes of exposure to the test compound(s). Chromakalim served as the positive control for the experiment. Ring relaxation was measured by the isometric method as gram changes. Relaxation of the vein rings in this assay are a function of both K ATP  channel agonization and NO response. In prior published work, about half of the relaxation response could be attributable to K ATP  channel agonization and half to a NO-mediated response. Each assay was run in duplicate. 
     Based on prior published data using arterial rings, 100 μM zofenopril achieved a maximal relaxation response (J Pharmacol. Exp. Therapeutics; 1993; 265(2):609-618). In a published study with nicorandil using human umbilical artery segments, 10 μM of nicorandil induced relaxation that was about 10% of the maximum, 30 μM induced relaxation that was about 60% of maximum while 100 μM induced maximal relaxation (Eur J Cardio-Thorac. Surg.; 2000; 17:319-324). 
     Eight combinations of concentration of zofenopril and nicorandil were tested in the assay. These were 80 and 40 μM nicorandil, 100 and 50 μM zofenopril, 12.5 μM zofenopril+10 μM nicorandil, 12.5 μM zofenopril+20 μM nicorandil, 12.5 μM zofenopril+40 μM nicorandil, and 25 μM zofenopril+40 μM nicorandil. 
     In this assay, 40 μM nicorandil achieved a maximal relaxation response. Consistent with the value reported in the literature, 100 μM zofenopril did achieve a maximal response which was only about 85% of the positive control. Given that 40 μM nicorandil achieved a maximal relaxation response in this assay, the further addition of zofenopril to 40 μM nicorandil could not further increase the relaxation response, which, pooled across the 40 μM nicorandil, 12.5 μM zofenopril+40 μM nicorandil, and 25 μM zofenopril+40 μM nicorandil, was equivalent to 103.6% of the positive control. The remaining combinations show the potential additivity of nicorandil and zofenopril. In this assay, a zofenopril concentration of 50 μM achieved relaxation of 60% of the positive control, or about 70% of the maximum response for zofenopril. The combination of 12.5 μM zofenopril+10 μM nicorandil (equal to concentrations that were ⅛ the maximum for zofenopril and ¼ the maximum for nicorandil) achieved relaxation of 63%, which was equivalent to about 74% of the maximal relaxation response for zofenopril and 61% of the maximal response for nicorandil. Based on additivity of effects, assuming a linear response curve, this combination was expected to have induced relaxation that was approximately 37% of the positive control (equivalent to 43.5% of the maximal response for zofenopril or 36% of the maximal response for nicorandil). Based on the published literature, 10 μM nicorandil alone had a very limited vasorelaxation response (˜10% of maximum), rather than the value used to calculate the response under the assumption of additivity. Similarly, the combination of 12.5 μM zofenopril +20 μM nicorandil (equal to concentrations that were ⅛ the maximum for zofenopril and ½ the maximum for nicorandil) achieved relaxation that was 92% of the positive control, greater than the maximal response for zofenopril, and 89% of the maximum for nicorandil. Based on additivity of effects, this combination was expected to have induced relaxation that was approximately 62% of the positive control (equivalent to 73% of the maximum for zofenopril or 60% of the maximum for nicorandil). These latter two results show that at substantially submaximal concentrations of nicorandil and zofenopril, the in-vitro response, that comprises both K ATP  channel agonization and NO-mediated contributions, is greater than would be predicted by additivity of effects. Put another way, the addition of a low dose of zofenopril, which probably has a very limited direct effect, to low concentrations of nicorandil, substantially and synergistically enhances the therapeutic response over what would be achieved with nicorandil alone. The concentrations tested are in the same range as the circulating drug levels following dosing with nicorandil at 5 mg TID. The C max  following a 5 mg dose is expected to be 15-16 μM, while C avg  is substantially lower than that.
