or separate fund of any kind or a fiduciary relationship between the Company and a Participant or any other person. To the extent any person acquires a right to receive payments from the Company pursuant to an Award, such right shall be no greater
than the right of any unsecured general creditor of the Company.

unless such action is approved by the shareholders of the Company. Notwithstanding the foregoing, no termination or amendment of the Plan may, without the consent of the Participant to whom a payment under an Award has been determined for a
completed Performance Period but not yet paid, adversely affect the rights of such Participant in such Award. 
 SECTION
14.    INTERPRETATION:    It is the intent of the Company that Awards made shall constitute "qualified performance-based compensation" satisfying the requirements of Section 162(m) of the Code.
Accordingly, the provisions of the Plan shall be interpreted in a manner consistent with Section 162(m) of the Code. If any provision of the Plan or an Award is intended to but does not comply or is inconsistent with the requirements of
Section 162(m) of the Code, such provision shall be construed or deemed amended to the extent necessary to conform to and comply with such requirements.

 SALIX ACQUIRES BUDESONIDE PRODUCTS FROM DR. FALK PHARMA 
 RALEIGH, NC, March 13, 2008 - Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announced that Dr Falk Pharma has granted Salix a license to its family of budesonide
products in the United States, which includes a patent-protected budesonide rectal foam and a budesonide gastro-resistant capsule. The products are approved and marketed in Europe, in the United Kingdom and Germany. In the United States the rectal
foam and gastro-resistant capsule products have patent coverage until 2015 and 2016, respectively. Salix is required to make an up-front payment and regulatory milestone payments to Dr. Falk Pharma, with the majority contingent upon achievement
of U.S. regulatory approval. In addition, Salix will pay royalties on net sales. The up-front payment and any 2008 development-related costs associated with these products are incorporated into the Company’s previously stated guidance for 2008.

 Budesonide is a potent steroid that undergoes rapid and extensive first pass metabolism.
Dr. Falk Pharma markets budesonide in the United Kingdom as Budenofalk® 2mg Rectal Foam for the treatment of distal active ulcerative colitis and as Budenofalk® 3mg Gastro-resistant Capsules for the induction of remission of mild to moderate active Crohn’s disease or the symptomatic relief of chronic diarrhea due to collagenous colitis.

 Salix Pharmaceuticals, Ltd., headquartered in Raleigh, North Carolina, develops and markets prescription pharmaceutical products for the treatment of
gastrointestinal diseases. Salix’s strategy is to in-license late-stage or marketed proprietary therapeutic drugs, complete any required development and regulatory submission of these products, and market them through the Company’s
gastroenterology specialty sales and marketing team. 
 Salix trades on the NASDAQ Global Select Market under the ticker symbol “SLXP.”

 -For the treatment of active ulcerative colitis that is limited to the rectum and the sigmoid colon. 
  

	4.2.	Posology and method of administration 

 Posology:

 Adults aged > 18 years: 
 One actuation of 2 mg budesonide daily. 
 Children: 
 Budenofalk® 2mg rectal foam should not
be taken by children due to insufficient experience in this age group. 
 Method of Administration: 
 Budenofalk® 2mg rectal foam can be
applied in the morning or evening. 
 The canister is first fitted with an applicator
and then shaken for about 15 seconds before the applicator is inserted into the rectum as far as comfortable. Note that the dose is only sufficiently accurate when the pump dome is held downwards as vertically as possible. To administer a dose of
Budenofalk® 2mg rectal foam, the pump dome is fully pushed down and very slowly released. Following the activation the applicator should be held in position for 10-15 seconds before being
withdrawn from the rectum. 
 The best results are obtained when the intestine is
evacuated prior to administration of Budenofalk® 2mg rectal foam. 

 Method of Administration: 
 Budenofalk® 2mg rectal foam can be
applied in the morning or evening. 
 The attending physician determines the duration
of use. An acute episode generally subsides after 6 to 8 weeks. Budenofalk® 2mg rectal foam should not be used after this time. 
  

	4.3.	Contraindications: 

 Budenofalk® 2mg rectal foam must not be used in: 
 - hypersensitivity to budesonide or any of the ingredients 
 - hepatic cirrhosis with signs of portal hypertension, e.g. late-stage
primary biliary cirrhosis 
  

	4.4.	Special warnings and precautions for use 

 Treatment with Budenofalk® 2mg rectal
foam results in lower systemic steroid levels than oral therapy with systemically acting corticoids. Transfer from other steroid therapy may result in symptoms relating to the change in systemic steroid levels. Caution is required in patients with
tuberculosis, hypertension, diabetes mellitus, osteoporosis, peptic ulcer, glaucoma, cataracts, family history of diabetes, family history of glaucoma. 
 Infection: 
 Suppression of the inflammatory response and immune function
increases the susceptibility to infections and their severity. The risk of deterioration of bacterial, fungal, amoebic, and viral infections during glucocorticoid treatment should be carefully considered. The clinical presentation may often be
atypical and serious infections such as septicaemia and tuberculosis may be masked and may reach an advanced stage before being recognised. 
 Chickenpox: Chickenpox is of particular concern since this normally minor illness may be fatal in immunosuppressed patients. Patients without a definite history of chickenpox should be advised to avoid close personal contact
with chickenpox or herpes zoster and if exposed they should seek urgent medical attention. If the patient is a child, parents must be given the above advice. Passive immunisation with varicella-zoster immunoglobulin (VZIG) is needed by exposed
non-immune patients who are receiving systemic corticosteroids or who have used them within the previous 3 months; this should be given within 10 days of exposure to chickenpox. If a diagnosis of chickenpox is confirmed, the illness warrants
specialist care and urgent treatment. In some cases corticosteroids should not be stopped and the dose may need to be increased. 
 Measles: Patients with compromised immunity who have come into contact with measles should, wherever possible, receive normal immunoglobulin as soon as possible after exposure. 
 Live vaccines: Live vaccines should not be given to individuals with impaired immune responsiveness. The antibody response to other
vaccines may be diminished. 
 In patients with severe liver function disorders, the elimination of glucocorticoids 

 
including Budenofalk® 2mg rectal foam will be reduced, and their systemic bioavailability will be
increased. 
 Corticosteroids may cause suppression of the HPA axis and reduce the stress response. Where patients are subject to surgery or
other stresses, supplementary systemic glucocorticoid treatment is recommended. 
 Concomitant treatment with ketoconazole or other CYP3A4
inhibitors should be avoided (see section 4.5). 
  

	4.5.	Interaction with other medicinal products and other forms of interaction 

 Pharmacodynamic interactions 
 Cardiac glycosides: 
 The action of the glycoside can be potentiated by potassium deficiency. 
 Saluretics: 
 Potassium excretion can be enhanced. 
 Pharmacokinetic interactions 
 Cytochrome P450: 
 - CYP3A4 inhibitors: 
 Ketoconazole 200 mg once daily p.o. increased the plasma concentrations of budesonide (3 mg single dose) approximately 6-fold during concomitant
administration. When ketoconazole was administered 12 hours after budesonide, the concentrations increased approximately 3-fold. As there are not enough data to give dose recommendations, the combination should be avoided. 
 Other potent inhibitors of CYP3A4 such as ritonavir, itraconazole, and clarithromycin are also likely to give a marked increase of the plasma
concentrations of budesonide. In addition, concomitant intake of grapefruit juice should be avoided. 
 - CYP3A4 inducers: 

Compounds or drugs such as carbamazepine and rifampicin, which induce CYP3A4, might reduce the systemic but also the local exposure of budesonide at
the gut mucosa. An adjustment of the budesonide dose might be necessary. 
 - CYP3A4 substrates: 
 Compounds or drugs which are metabolized by CYP3A4 might be in competition with budesonide. This might lead to an increased budesonide plasma
concentration if the competing substance has a stronger affinity to CYP3A4, or - if budesonide binds stronger to CYP3A4 - the competing substance might be increased in plasma and a doseadaptation/reduction of this drug might be required. 

Elevated plasma concentrations and enhanced effects of corticosteroids have been reported in women also receiving oestrogens or oral contraceptives,
but this has not been observed with oral low dose combination contraceptives. 

	4.6.	Pregnancy and lactation 

 Administration during pregnancy should be avoided unless there are compelling reasons for Budenofalk® 2mg rectal foam therapy. In pregnant animals,
budesonide, like other glucocorticosteroids, has been shown to cause abnormalities of foetal development. The relevance of this to man has not been established. Since it is not known if budesonide passes into breast milk, the infant should not be
breast-fed during treatment with Budenofalk® 2mg rectal foam. 
  

	4.7.	Effects on ability to drive and use machines 

 No
effects are known. 
  

	4.8.	Undesirable Effects 

 Occasionally side effects may
occur which are typical for systemically acting glucocorticosteroids. These side effects depend on the dosage, the period of treatment, concomitant or previous treatment with other glucocorticosteroids and the individual sensitivity. 
 Immune system disorders: 
 Interference with the immune response (e.g. increase in risk of infections). An exacerbation or the reappearance of extraintestinal manifestations (especially affecting skin and joints) can occur on switching a patient from the systemically
acting glucocorticosteroids to the locally acting budesonide. 
 Metabolism and nutrition disorders: 
 Cushing’s syndrome: moon-face, truncal obesity, reduced glucose tolerance, diabetes mellitus, sodium retention with oedema formation, increased
excretion of potassium, inactivity or atrophy of the adrenal cortex, growth retardation in children, disturbance of sex hormone secretion (e.g. amenorrhoea, hirsutism, impotence) 
 Nervous system disorders: 
 depression, irritability, euphoria in isolated cases (< 1/10,000): pseudotumor cerebri (including papilloedema) in adolescents. 
 Eye disorders:  
 glaucoma, cataract 
 Vascular disorders: 
 hypertension, increased risk of thrombosis, vasculitis (withdrawal syndrome
after long-term therapy) 
 Gastro intestinal disorders: 
 stomach complaints, duodenal ulcer, pancreatitis, constipation 

 Skin and subcutaneous tissue disorders: 
 allergic exanthema, red striae, petechiae, ecchymoses, steroid acne, delayed wound healing. 
 Due to the sorbic acid content local skin reactions may occur, e.g. contact dermatitis. 
 Musculoskeletal, connective tissue and bone disorders : 
 aseptic necrosis of bone (femur and head of the humerus), diffuse muscle pain and weakness, osteoporosis. 
 General disorders: 
 Tiredness, malaise. 
 Some of the undesired effects were reported after long-term use of orally administered budesonide. 
 Due to its local action, the risk of unwanted effects of Budenofalk® 2mg rectal foam is generally lower than when taking systemically acting glucocorticoids.] 
  

	4.9.	Overdose 

 To date, no cases of overdosage with budesonide are known. In view of the properties of budesonide contained in Budenofalk® 2mg rectal foam, an overdose
resulting in toxic damage is extremely unlikely. 
  

	5.	PHARMACOLOGICAL PROPERTIES 

  

	5.1.	Pharmacodynamic properties 

 Pharmacotherapeutic
group: Intestinal Antiinflammatory Agents 
 ATC code: A07EA06 
 The exact mechanism of action of budesonide in the treatment of ulcerative colitis/procto-sigmoiditis is not fully understood. Data from clinical pharmacology studies and controlled clinical trials strongly indicate
that the mode of action of budesonide is predominantly based on a local action in the gut. Budesonide is a glucocorticosteroid with a high local anti-inflammatory effect. At a dosage of 2 mg budesonide, applied rectally, which is clinically
equieffective to systemically acting glucocorticoids, budesonide leads to practically no suppression of the hypothalamus-hypophysis-adrenal cortex axis. 
 Budenofalk® 2mg rectal foam
investigated up to the daily dosage of 4 mg budesonide showed virtually no influence on the plasma cortisol level. 
  

	5.2.	Pharmacokinetic properties 

 Absorption: 

 After oral application the systemic availability
of budesonide is about 10%. After rectal administration the areas under the concentration time curves are slightly higher than in historical controls. Peak levels are obtained after an average of 2-3 hours after administering Budenofalk® 2mg rectal foam. 
 Distribution: 
 Budesonide has a high volume of distribution (about 3 1/kg). Plasma protein binding averages 85 -90%. 
 Biotransformation: 
 Budesonide
undergoes extensive biotransformation in the liver (approximately 90 %) to metabolites of low glucocorticosteroid activity. The glucocorticosteroid activity of the major metabolites, 6â-hydroxybudesonide and 16á-hydroxyprednisolone, is
less than 1 % of that of budesonide. 
 Elimination: 
 The average elimination half-life is about 3 - 4 hours. The mean clearance rate is about 10 - 15 l/min for budesonide, determined by HPLC-based methods.

 Spread: 
 A scintigraphic investigation with technetium-marked Budenofalk® 2mg rectal foam on patients with ulcerative colitis showed that the foam spreads out over the entire sigmoid. 
 Specific patient populations (liver diseases): 
 Dependent on the type and severity of liver diseases the metabolism
of budesonide might be decreased. 
  

	5.3.	Preclinical safety data 

 Preclinical investigations on dogs have shown that Budenofalk® 2mg rectal foam is well tolerated locally. 
 Preclinical data in acute, subchronic and chronic toxicological studies with budesonide showed atrophies of the thymus gland and adrenal cortex and a
reduction especially of lymphocytes. These effects were less pronounced or at the same magnitude as observed with other glucocorticosteroids. These steroid effects might also be of relevance in man. 
 Budesonide had no mutagenic effects in a number of in vitro and in vivo tests. 
 A slightly increased number of basophilic hepatic foci were observed in chronic rat studies with budesonide, and in carcinogenicity studies there was an
increased incidence of primary hepatocellular neoplasms, astrocytomas (in male rats) and mammary tumours (female rats) observed. These tumours are probably due to the specific steroid receptor action, increased metabolic burden on the liver and
anabolic effects, effects which are also known from other glucocorticosteroids in rat studies and therefore represent a class effect. No similar effects have ever been observed in man for budesonide, neither in clinical 

 
trials nor from spontaneous reports. 
 In
general, preclinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential. 
 In pregnant animals, budesonide, like other glucocorticosteroids, has been shown to cause abnormalities of foetal development, but the relevance to man
has not been established (see also section 4.6).

 B.     ORAL PRODUCT SUMMARY 
 BUDENOFALK 3MG GASTRO-RESISTANT CAPSULES 
  

	1.	NAME OF THE MEDICINAL PRODUCT 

 Budenofalk 3 mg
gastro-resistant capsules 
  

	2.	QUALITATIVE AND QUANTITATIVE COMPOSITION 

 Each
capsule contains 3 mg budesonide 
 For excipients, see 6.1 
  

	3.	PHARMACEUTICAL FORM 

 Gastro-resistant capsules,
hard 
 Capsule, hard, pink containing white gastro-resistant granules. 
  

	4.	CLINICAL PARTICULARS 

  

	4.1.	Therapeutic indications 

 -Induction of remission in
patients with mild to moderate active Crohn’s disease affecting the ileum and/or the ascending colon. 
 -Symptomatic relief of chronic
diarrhoea due to collagenous colitis 
 Please note: 
 Treatment with Budenofalk 3 mg does not appear useful in patients with Crohn’s disease affecting the upper gastro-intestinal tract. Extraintestinal symptoms, e.g. involving the skin, eyes or joints, are unlikely
to respond to Budenofalk 3 mg because of its local action. 
  

	4.2.	Posology and method of administration 

 Posology: 
 Adults aged > 18 years: 
 The recommended daily dose is one capsule (containing 3 mg budesonide) three times daily (morning, midday and evening) about a half hour before meals. 
 Children: 
 Budenofalk 3 mg should not
be taken by children due to insufficient experience in this age group. 
 Method of Administration: 
 The capsules containing the gastro-resistant granules should be taken before meals, swallowed whole with plenty of fluid (e.g. a glass of water).

 The duration of treatment in active Crohn’s Disease and in collagenous colitis should be limited to
8 weeks. 
 The treatment with Budenofalk 3 mg should not be stopped abruptly, but withdrawn gradually (tapering doses). In the first week,
the dosage should be reduced to two capsules daily, one in the morning, one in the evening. In the second week, only one capsule should be taken in the morning. Afterwards treatment can be stopped. 
  

	4.3.	Contra-indications: 

 Budenofalk 3 mg must not be
used in: 
 - hypersensitivity to budesonide or any of the ingredients 
 - hepatic cirrhosis with signs of portal hypertension, e.g. late-stage primary biliary cirrhosis 
  

	4.4.	Special warnings and special precautions for use 

 Treatment with Budenofalk 3 mg results in lower systemic steroid levels than conventional oral steroid therapy. Transfer from other steroid therapy may result in symptoms relating to the change in systemic steroid levels. Caution is
required in patients with tuberculosis, hypertension, diabetes mellitus, osteoporosis, peptic ulcer, glaucoma, cataracts, family history of diabetes, family history of glaucoma. 
 Infection: 
 Suppression of the
inflammatory response and immune function increases the susceptibility to infections and their severity. The risk of deterioration of bacterial, fungal, amoebic and viral infections during glucocorticoid treatment should be carefully considered. The
clinical presentation may often be atypical and serious infections such as septicaemia and tuberculosis may be masked, and therefore may reach an advanced stage before being recognised. 
 Chickenpox: Chickenpox is of particular concern since this normally minor illness may be fatal in immunosuppressed patients. Patients
without a definite history of chickenpox should be advised to avoid close personal contact with chickenpox or herpes zoster and if exposed they should seek urgent medical attention. If the patient is a child, parents must be given the above advice.
Passive immunisation with varicella zoster immunoglobulin (VZIG) is needed by exposed non-immune patients who are receiving systemic corticosteroids or who have used them within the previous 3 months; this should be given within 10 days of exposure
to chickenpox. If a diagnosis of chickenpox is confirmed, the illness warrants specialist care and urgent treatment. Corticosteroids should not be stopped and the dose may need to be increased. 
 Measles: Patients with compromised immunity who have come into contact with measles should, wherever possible, receive normal immunglobulin
as soon as possible after exposure. 
 Live vaccines: Live vaccines should not be given to individuals with impaired immune
responsiveness. The antibody response to other vaccines may be diminished. 

 In patients with severe liver function disorders, the elimination of glucocorticosteroids including
Budenofalk will be reduced, and their systemic bioavailability will be increased. 
 Corticosteroids may cause suppression of the HPA axis
and reduce the stress response. Where patients are subject to surgery or other stresses, supplementary systemic glucocorticoid treatment is recommended. 
 Concomitant treatment with ketoconazole or other CYP3A4 inhibitors should be avoided (see section 4.5) 
 Budenofalk 3mg capsules contain lactose and sucrose. Patients with rare hereditary problems of galactose or fructose intolerance, glucose-galactose malabsorption, sucrase-isomaltase insufficiency, the Lapp lactase deficiency or the
congenital lactase deficiency should not take this medicine. 
  

	4.5.	Interaction with other medicinal products and other forms of interaction  

 Pharmacodynamic interactions 
 Cardiac glycosides: 
 The action of the glycoside can be potentiated by potassium deficiency. 
 Saluretics: 
 Potassium excretion can be enhanced. 
 Pharmacokinetic interactions 
 Cytochrome P450: 
 - CYP3A4 inhibitors: 
 Ketoconazole 200 mg once daily p.o. increased the plasma concentrations of budesonide (3 mg single dose) approximately 6-fold during concomitant
administration. When ketoconazole was administered 12 hours after budesonide, the concentrations increased approximately 3-fold. As there are not enough data to give dose recommendations, the combination should be avoided. 
 Other potent inhibitors of CYP3A4 such as ritonavir, itraconazole, and clarithromycin are also likely to give a marked increase of the plasma
concentrations of budesonide. In addition, concomitant intake of grapefruit juice should be avoided. 
 - CYP3A4 inducers: 

Compounds or drugs such as carbamazepine and rifampicin, which induce CYP3A4, might reduce the systemic but also the local exposure of budesonide at
the gut mucosa. An adjustment of the budesonide dose might be necessary. 
 - CYP3A4 substrates: 
 Compounds or drugs which are metabolized by CYP3A4 might be in competition with budesonide. This might lead to an increased budesonide plasma
concentration if the competing substance has a stronger affinity to CYP3A4, or - if budesonide binds stronger to CYP3A4 - the competing substance might be increased in plasma and a dose- 

 
adaption/reduction of this drug might be required. 
 Elevated plasma concentrations and enhanced effects of corticosteroids have been reported in women also receiving oestrogen’s or oral contraceptives, but this has not been observed with oral low dose combination contraceptives.

 Cimetidine at recommended doses in combination with budesonide has a small but insignificant effect on pharmacokinetics of budesonide.
Omeprazole has no effect on the pharmacokinetics of budesonide. 
 Steroid-binding compounds: 
 In theory, potential interactions with steroid-binding synthetic resins such as cholestyramine, and with antacids cannot be ruled out. If given at the
same time as Budenofalk 3 mg, such interactions could result in a reduction in the effect of budesonide. Therefore these preparations should not be taken simultaneously, but at least two hours apart. 
  

	4.6.	Use during pregnancy and lactation 

 Administration
during pregnancy should be avoided unless there are compelling reasons for Budenofalk 3 mg therapy. In pregnant animals, budesonide, like other glucocorticosteroids, has been shown to cause abnormalities of foetal development. The relevance of this
to man has not been established. 
 Since it is not known if budesonide passes into breast milk, the infant should not be breast-fed during
treatment with Budenofalk 3 mg. 
  

	4.7.	Effects on ability to drive and use 

 machines No effects are known. 
  

	4.8.	Undesirable Effects 

 The following undesirable
effects and frequencies of Budenofalk 3 mg have been spontaneously reported: 
 Very rare (<1/10,000), including isolated
reports: 
  

	 	•	 	 Metabolism and nutritional disorders: oedema of legs, Cushing’s syndrome. 

  

	 	•	 	 Nervous system disorders: Pseudotumor cerebri (including papilloedema) in adolescents. 

  

	 	•	 	 Gastrointestinal disorders: Constipation. 

  

	 	•	 	 Musculoskeletal, connective tissue and bone disorders: diffuse muscle pain and weakness, osteoporosis. 

  

	 	•	 	 General disorders: tiredness, malaise. 

 Some of the undesired effects were reported after long-term use. 
 Occasionally side effects may occur which
are typical for systemic glucocorticosteroids. These side effects depend on the dosage, the period of treatment, concomitant or previous treatment with other glucocorticosteroids and the individual sensitivity. 
 Clinical studies showed that the frequency of glucocorticosteroid associated side effects is 

 
lower with Budenofalk 3 mg (approx. by half) than with oral treatment of equivalent dosages of prednisolone. 
 Immune system disorders: 
 Interference with the immune response (e.g. increase in risk of infections). 
 An exacerbation or the reappearance of
extraintestinal manifestations (especially affecting skin and joints) can occur on switching a patient from the systemically acting glucocorticosteroids to the locally acting budesonide. 
 Metabolism and nutrition disorders: 
 Cushing’s syndrome: moon-face, truncal obesity, reduced glucose tolerance, diabetes mellitus, sodium retention with oedema formation, increased excretion of potassium, inactivity or atrophy of the adrenal cortex, growth retardation in
children, disturbance of sex hormone secretion (e.g. amenorrhoea, hirsutism, impotence) 
 Nervous system disorders:  
 depression, irritability, 
 euphoria

 Eyes disorders: 
 glaucoma, 
 cataract 
 Vascular disorders: 
 hypertension, increased risk of thrombosis, vasculitis (withdrawal syndrome after longterm
therapy) 
 Gastro intestinal disorders: 
 stomach complaints, duodenal ulcer, pancreatitis 
 Skin and subcutaneous tissue disorders:

 allergic exanthema, red striae, petechiae, ecchymosis, steroid acne, delayed wound healing, contact dermatitis 
 Musculoskeletal, connective tissue and bone disorders : 
 aseptic necrosis of bone (femur and head of the humerus) 
  

	4.9.	Overdose 

 To date, no cases of overdosage with
budesonide are known. In view of the properties of budesonide contained in Budenofalk 3 mg, an overdose resulting in toxic damage is extremely unlikely. 
  

	5.	PHARMACOLOGICAL PROPERTIES 

  

	5.1.	Pharmacodynamic Properties 

 Pharmacotherapeutic
group: Glucocorticosteroid ATC code: A07EA06 
 The exact mechanism of budesonide in the treatment of Crohn’s disease is not fully
understood. Data from clinical pharmacology studies and controlled clinical trials 

 
strongly indicate that the mode of action of Budenofalk 3 mg capsules is predominantly based on a local action in the gut. Budesonide is a
glucocorticosteroid with a high local anti-inflammatory effect. At doses clinically equivalent to systemically acting glucocorticosteroids, budesonide gives significantly less HPA axis suppression and has a lower impact on inflammatory markers.

 Budenofalk 3 mg capsules show a dose-dependent influence on cortisol plasma levels which is at the recommended dose of 3 x 3 mg
budesonide/day significantly smaller than that of clinically equivalent effective doses of systemic glucocorticosteroids. 
  

	5.2.	Pharmacokinetic Properties 

 Absorption: 
 Budenofalk 3 mg capsules, which contain gastric juice resistant granules, have - due to the specific
coating of the granules - a lag phase of 2 - 3 hours. In healthy volunteers, as well as in patients with Crohn’s disease, mean maximal budesonide plasma concentrations of 1 - 2 ng/ml were seen at about 5 hours following an oral dose of
Budenofalk 3 mg capsules at a single dose of 3 mg, taken before meals. The maximal release therefore occurs in the terminal ileum and caecum, the main area of inflammation in Crohn’s disease. 
 In ileostomy patients, release of budesonide from Budenofalk 3 mg is comparable to healthy subjects or Crohn’s disease patients. In ileostomy
patients it was demonstrated that about 30-40% of released budesonide is still found in the ileostomy bag, indicating that a substantial amount of budesonide from Budenofalk 3 mg will be transferred normally into the colon. 
 Concomitant intake of food may delay release of granules from stomach by 2-3 hours, prolonging the lag phase to about 4-6 hours, without change in
absorption rates. 
 Distribution: 
 Budesonide has a high volume of distribution (about 3 l/kg). Plasma protein binding averages 85 -90%. 
 Biotransformation: 
 Budesonide undergoes extensive biotransformation in the liver (approximately 90 %) to metabolites
of low glucocorticosteroid activity. The glucocorticosteroid activity of the major metabolites, 6â-hydroxybudesonide and 16á-hydroxyprednisolone, is less than 1 % of that of budesonide. 
 Elimination: 
 The average
elimination half-life is about 3 - 4 hours. The systemic availability in healthy volunteers as well as in fasting patients with Crohn’s disease is about 9 - 13%. The clearance rate is about 10 - 15 l/min for budesonide, determined by HPLC-based
methods. 
 Specific patient populations (liver diseases): 
 Dependent on the type and severity of liver diseases and due to the fact that budesonide 

 
is metabolised by CYP3A4, the metabolization of budesonide might be decreased. Therefore, the systemic exposure of budesonide might be increased in patients
with impaired hepatic functions, as has been shown for patients with autoimmune hepatitis (AIH). With improving the liver function and disease, metabolization of budesonide will normalize. 
 The bioavailability of budesonide has been found to be significantly higher in patients in the late stage of primary biliary cirrhosis (PBC Stage IV)
than in patients in the early stages of primary biliary cirrhosis (PBC Stage I/II); on average, the areas under the plasma concentration-time curves were threefold greater in patients with late-stage PBC, following repeated administration of
budesonide 3 x 3 mg daily, than in patients with early-stage PBC. 
  

	5.3.	Preclinical safety data 

 Preclinical data in acute,
subchronic and chronic toxicological studies with budesonide showed atrophies of the thymus gland and adrenal cortex and a reduction especially of lymphocytes. These effects were less pronounced or at the same magnitude as observed with other
glucocorticosteroids. Like with other glucocorticosteroids, and in dependence of the dose and duration and in dependence of the diseases these steroid effects might also be of relevance in man. 
 Budesonide had no mutagenic effects in a number of in vitro and in vivo tests. 
 A slightly increased number of basophilic hepatic foci were observed in chronic rat studies with budesonide, and in carcinogenicity studies was an
increased incidence of primary hepatocellular neoplasms, astrocytomas (in male rats) and mammary tumors (female rats) observed. These tumors are probably due to the specific steroid receptor action, increased metabolic burden on the liver and
anabolic effects, effects which are also known from other glucocorticosteroids in rat studies and therefore represent a class effect. No similar effects have ever been observed in man for budesonide, neither in clinical trials nor from spontaneous
reports. 
 In general, preclinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated
dose toxicity, genotoxicity, carcinogenic potential. 
 In pregnant animals, budesonide, like other glucocorticosteroids, has been shown to
cause abnormalities of foetal development. But the relevance to man has not been established (see also section 4.6)
