CALCITONIN SUPPOSITORY FORMULATIONS

Abstract: Disclosed are rectal and vaginal suppository formulations comprising calcitonin and caprylic acid monoglyceride in a pharmaceutically acceptable suppository vehicle.

Description: CALCITONIN SUPPOSITORY FORMULATIONS Background of the Invention 1. Field of the Invention The present invention relates to a novel method of administering calcitonin to patients and to formulations adapted for rectal and vaginal administration. More particularly, the present invention relates to calcitonin-containing pharmaceutical formulations containing therein caprylic acid monoglycerida which promotes absorption of calcitonin and thereby enhances its bioavailability. 2. Description of the Prior Art The method of administration of pharmaceutically active calcitonin is predominantly by injection, although efforts were made in the prior art to use other modes of administration. While administration by injection is acceptable for short-term therapy, administration by injection to patients in need of long-term calcitonin therapy has serious problems. Not only is it costly to patients to have physicians do the administration for extended periods of time, but it is also painful and inconvenient. Nor can calcitonin be given orally to patients since oral administration will result in degradation of calcitonin. Recently, the prior art has found that calcitonin may also be administered via the rectal route; however, it was also found that certain absorption promoters enhance absorption of calcitonin through the rectal mucosa and as such may be used to advantage in calcitonin suppositories. Absorption promoters that provided increased absorption include certain surface ' active agents, amino acid derivatives, and certain nonsurfactant adjuvenants, such as, ethylacetoacetate, dimethylethoxymethyl- ene alonate, sodium salicylate and the like. SUMMARY OF THE INVENTION • This invention relates to a suppository formulation comprising: from about 0.0004% w/w to about 0.20% w/w, and preferably from about 0.005% w/w to about 0.05% w/w of calcitonin having a potency of about 25 to 6,000 IU/mg of peptide or higher as hereinafter defined; from about 2.5% w/w to about 50.0% w/w and preferably from about 10% w/w to about 40% w/w of caprylic acid monoglyceride and a pharmaceutically acceptable suppository vehicle. The invention also relates to a method for increasing the absorption of calcitonin through the rectal and/or vaginal mucosa by utilizing caprylic acid monoglyceride in the suppository formulations. Hereinafter the invention will be described with reference to rectal administration; however, it is to be noted that, vaginal administration is intended to be covered as well. According to the invention, there is also provided a method for the treatment of human patients suffering from diseases of hyperparathyroidism, idiopathic hypercalcemia of infancy, Paget's disease, vitamin D intoxication, or osteolytic bone metastases. Said diseases are characterized by hypercalcemia and high phosphate concentrations and their treatment is e fected by decreasing serum calcium and phosphate concentrations in the blood by rectal application of a calcitonin containing composition r.o effect control of said diseases by transmucosal action. The term calcitonin as used herein means not only polypeptides having a structure corresponding to one of the naturally occurring hormones, and which may be naturally or synthetically produced, but also analogs thereof and related synthetic peptides having calcitonin activity. 91/13601 DETAILED DESCRIPTION OF THE INVENTION In accordance with the present invention, suppository pharmaceutical formulations are provided in which caprylic acid monoglyceride is incorporated for enhancing the absorption of calcitonin through the rectal mucosa. The composition of the formulations are described hereunder. Calcitonin Calcitonin is a polypeptide hormone involved in the control of calcium metabolism in the body. All known natural calcitonin peptides contain an amino acid sequence of 32 amino acids, of which the seven at the amino terminal end of the peptide chain are held in a cyclic configuration by a sulphur or carbon bridge and the carboxyl terminal residue consists of proline amide. The natural calcitonins include the salmon, eel, bovin, porcine, ovine, rat and human calcitonins. The detailed structure within the peptide chain of the hormone varies among different species and while the hormones, and their derivatives and analogues found in various species are of interest for use in the present invention, salmon calcitonin is of special interest in view of its relatively hydrophobic character and its stability. Salmon calcitonin has the following formula: H-Cys-Ser-Asn-Leu-Ser-Thr-Cys-Val-Leu- 1 2 3 4 5 6 7 8 9 Gly-Lys-Leu-Ser-Gln-Glu-Leu-His-Lys-Leu- 10 11 12 13 14 15 16 17 18 19 Gln-Thr-Tyr-Pro-Arg-Thr-Asn-Thr-Gly- 20 21 22 23 24 25 26 27 28 Ser-Gly-Thr-Pro-NH2 29 30 31 32 In U.S. Pat. Nos. 3,926,938, 4,062,815, 3,929,758, 4,033,940, 4,336,187, 4,388,235, 4,391,747 and 4,401,593 are disclosed improved synthesis of calcitonins including the salmon calcitonin referred to above. Human, salmon and porcine calcitonins have been available for therapeutic use for several years. For example, synthetic salmon calcitonin is marketed by Armour Pharmaceutical Co. under the tradena e CALCIMAR in a sterile, lyophilized form reconstitutable for subcutaneous or intravascular injection for the treatment of bone diseases. The level of hypocalcemic activity of calcitonins varies from species to species. Salmon and chicken calcitonin have a potency of about 4,000 to 6,000 MCR (Medical Research Council) U/mg peptide; eel calcitonin about 2,000 to 4,000 MRC U/mg peptide; rat 400 MRC U/mg; while beef, sheep, hog and man about 100 to 200 MRC U/mg peptide. Calcitonin used by the present invention may be obtained from Armour Pharmaceutical Co., from natural sources, or by synthetic routes known in the art. The synthesis can be performed by classical peptide synthesis as well as by solid phase synthesis. In addition to .the above-described calcitonins, the present invention encompasses synthetic calcitonin peptides having biological activity of the same type as those above-described. Such synthetic calcitonins are disclosed, along with processes for preparation thereof in the following U.S. Pat.

Caprylic acid monoglyceride or glyceryl caprylate may be obtained by using a state-of-the-art method of preparation, or it may be obtained from commercial suppliers, such as Dynamit Nobel under the tradename Imwitor 308, which contains a mixture of mono-, di- and triglycerides of caprylic acid with a typical ratio of 60:30:10. As used in connection with the specification and claims of the present invention, the term caprylic acid monoglyceride will be used to denote the commercially supplied mixture of mono-, di- and triglycerides of caprylic.acid. The Suppository Vehicle The biologically/pharmacologically active calcitonin,. as hereinbefore defined, and caprylic acid monoglyceride are formulated with a suppository vehicle adapted for rectal administration. The suppository vehicle comprises a suppository base and certain adjuvenants and additives suitable for making such formulations. The suppository base may be an aqueous or a fatty base material, the latter being preferred mainly for ease of formulation and administration. The fatty base material for use in the present invention includes: fatty oils and fats, such as cocoa butter, palm oil, coconut oil, lard; waxes, such as lanolin and vasoline; fatty acids, such as, oleic-, stearic-, and lauric acids. We prefer to use a suppository base consisting essentially of polyethylene glycols or mixtures of mono-, di-, and triglycerides of fatty acids of Cχo to C 2 α chain length. These are obtainable as polyethylene glycol 1,000-8,000 (PEG - 91/13601 19 polymer σf ethylene oxide, ol. wt. 1,000-8,000); cocoa butter, NF (fat obtained from the roasted seed of Theobroma cacao) ; Suppocire AIX (semi-synthetic glycerides with ethoxylated fatty acid esters containing 95% mono-, di- and triglycerides and 5% polysorbate 65) ; Witepsol S 55 (semi-synthetic glycerides with ethoxylated fatty acid esters containing 98% mono-, di- and triglycerides and 2% PEG25 - cetyl stearyl alcohol) and Witepsol E75, supplied by Dyna it Nobel, which is glyceryl esters of saturated fatty acids of chain length Cχo-C 8. The preparations of the present invention may also contain other additives, such as antioxidants, stabilizers, viscosity builders, preservatives, and the like. The concentration of • these additives may vary according to the particular additive used and the desired result sought. The use of the kind and concentration of additives are well within the ability of the skilled artisan. We contemplate three methods by which calcitonin can be incorporated into the suppository system, namely, by the use of: 1) a buffer system, 2) a gelatin stabilizer and 3) a bulking agent. 1) According to this method, a buffer system is used as a carrier for the calcitonin which provides stability for the same and facilitates its admixture with the suppository vehicle. The buffer system of the present invention preferably contains a sodium or potassium phosphate/phosphoric acid buffer or a sodium or potassium acetate/acetic acid buffer or a sodium or potassium citrate/citric acid buffer in the range of 0.01 M to 0.5M and preferably in the range of 0.05 M to 0.2 M. The. pH range of these buffers are between 2.0 to 8.0. This 91/13601 20 concentration was found effective to provide stability of the dissolved calcitonin in the vehicle. 2) According to this method, the stabilizer system < contains from about l to about 32% w/w of a gelatin hydrolized in a 0.9% w/w sodium chloride solution or in purified water. The pH range of the stabilizer system is between 2.0 to 8.0. This stabilizer system has been found very effective in providing •^stability to the dissolved calcitonin. 3) According to this method, a lyophilized or dry mixed bulking agent is used as a carrier for calcitonin. The ratio of calcitonin to the bulking powder is about 10 to 60,000 IU per mg. Examples of bulking agents include, but are not limited to, gelatin, methionine, dextrose, sucrose, mannitol, sorbitol, lactose, methyl cellulose, povidone, sodium chloride and sodium acetate. Preparation of the Formulations In general the preparation of the formulations of the present invention is as follows: the absorption promoter is melted with the suppository base; antioxidants, such as BHA (butylated hydroxyanisole, USP) and BHT (butylated hydroxytoluene, USP) are added thereto and dissolved thereby forming the suppository vehicle; calcitonin is dissolved in a buffer solution or a stabilizer system or homogenously distributed in a bulk powder mix and is blended with the suppository vehicle; and the formulation is then poured into suitable suppository molds and allowed to solidify.
