The safety of budesonide extended-release tablets has been evaluated in controlled and open-label clinical trials which enrolled a combined total of 1,105 patients with ulcerative colitis. In two 8-week, placebo-controlled studies in patients with active disease (Study 1 and Study 2), a total of 255 patients received budesonide extended-release tablets 9 mg, 254 patients received budesonide extended-release tablets 6 mg, and 258 patients received placebo. They ranged in age from 18-77 years (mean=43), 56% were male, and 75% were Caucasian. The most common adverse reactions were headache, nausea, decreased blood cortisol, upper abdominal pain, fatigue, flatulence, abdominal distension, acne, urinary tract infection, arthralgia, and constipation. The adverse reactions occurring in 2% or more of patients on therapy with budesonide extended-release tablets 9 mg are summarized in Table 1.

7 DRUG INTERACTIONS Avoid cytochrome P450 3A4 inhibitors (e.g., ketoconazole, grapefruit juice). May cause increased systemic corticosteroid effects. ( 2.2 , 7 , 12.3 ) 7.1 Interaction with CYP3A4 Inhibitors Concomitant oral administration of ketoconazole (a known inhibitor of CYP3A4 activity in the liver and in the intestinal mucosa) caused an eight-fold increase of the systemic exposure to oral budesonide. If treatment with inhibitors of CYP3A4 activity (such as ketoconazole, itraconazole, ritonavir, indinavir, saquinavir, erythromycin) is indicated, discontinuation of budesonide extended-release tablets should be considered. After extensive intake of grapefruit juice (which inhibits CYP3A4 activity predominantly in the intestinal mucosa), the systemic exposure for oral budesonide increased about two times. Ingestion of grapefruit or grapefruit juice should be avoided in connection with budesonide extended-release tablets administration [see Dosage and Administration ( 2 ) and Clinical Pharmacology ( 12.3 )]. 7.2 Inhibitors of Gastric Acid Secretion Since the dissolution of the coating of budesonide extended-release tablets are pH dependent, the release properties and uptake of the compound may be altered when budesonide extended-release tablets are used after treatment with gastric acid reducing agents (e.g., proton pump inhibitors (PPIs), H 2 blockers and antacids).

8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm. ( 8.1 ) Hepatic Impairment: Monitor patients for signs and/or symptoms of hypercorticism. ( 5. 5 , 8.6 ) 8.1 Pregnancy Risk Summary Limited published studies report on the use of budesonide in pregnant women; however, the data are insufficient to inform a drug-associated risk for major birth defects and miscarriage. There are clinical considerations (see Clinical Considerations). In animal reproduction studies with pregnant rats and rabbits, subcutaneous administration of budesonide during organogenesis at doses 0.5 times and 0.05 times, respectively, the maximum recommended human dose, resulted in increased fetal loss, decreased pup weights, and skeletal abnormalities. Maternal toxicity was observed in both rats and rabbits at these dose levels ( see Data ). Based on animal data, advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage of the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4%, and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryofetal Risk Published data suggest that increased disease activity is associated with the risk of developing adverse pregnancy outcomes in women with ulcerative colitis. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth. Fetal/Neonatal Adverse Reactions Hypoadrenalism may occur in infants born of mothers receiving corticosteroids during pregnancy. Infants should be carefully observed for signs of hypoadrenalism, such as poor feeding, irritability, weakness, and vomiting, and managed accordingly [ see Warnings and Precautions ( 5.1 )] . Data Animal Data Budesonide was teratogenic and embryolethal in rabbits and rats. In an embryofetal development study in pregnant rats dosed subcutaneously with budesonide during the period of organogenesis from gestation days 6-15 there were effects on fetal development and survival at subcutaneous doses up to approximately 500 mcg/kg in rats (approximately 0.5 times the maximum recommended human dose on a body surface area basis). In an embryofetal development study in pregnant rabbits dosed during the period of organogenesis from gestation days 6-18, there was an increase in maternal abortion, and effects on fetal development and reduction in litter weights at subcutaneous doses up to approximately 25 mcg/kg in rabbits (approximately 0.05 times the maximum recommended human dose on a body surface area basis). Maternal toxicity, including reduction in body weight gain, was observed at subcutaneous doses of 5 mcg/kg in rabbits (approximately 0.01 times the maximum recommended human dose on a body surface area basis) and 500 mcg/kg in rats (approximately 0.5 times the maximum recommended human dose on a body surface area basis). In a peri- and postnatal development study, rats dosed subcutaneously with budesonide during the period of Day 15 post coitum to Day 21 postpartum, budesonide had no effects on delivery but did have an effect on growth and development of offspring. In addition, offspring survival was reduced, and surviving offspring had decreased mean body weights at birth and during lactation at exposures 0.02 times the MRHD (on a mg/m 2 basis at maternal subcutaneous doses of 20 mcg/kg/day and higher). These findings occurred in the presence of maternal toxicity. 8.2 Lactation Risk Summary Lactation studies have not been conducted with budesonide extended-release tablets or other oral budesonide products and no information is available on the effects of budesonide on the breastfed infant or the effects of the drug on mil …

12.1 Mechanism of Action Budesonide has a high topical glucocorticosteroid (GCS) activity and substantial first-pass elimination. The formulation contains budesonide in an extended-release tablet core. The tablet core is enteric coated to protect dissolution in gastric juice which delays budesonide release until exposure to a pH ≥7 in the small intestine. Upon disintegration of the coating, the core matrix provides extended release of budesonide in a time dependent manner.

11 DESCRIPTION Budesonide extended-release tablets, for oral administration, contain budesonide, a synthetic corticosteroid, as the active ingredient. Budesonide is designated chemically as (RS)-11β, 16α, 17,21 tetrahydroxypregna-1,4-diene-3,20-dione cyclic 16,17-acetal with butyraldehyde. Budesonide is provided as a mixture of two epimers (22R and 22S). The empirical formula of budesonide is C 25 H 34 O 6 and its molecular weight is 430.5. Its structural formula is: Budesonide is a white to off-white, odorless, crystalline powder that is practically insoluble in water, sparingly soluble in alcohol, and freely soluble in chloroform. Budesonide extended-release tablets, a delayed and extended-release tablet, is coated with a polymer film, which breaks down at or above pH 7. The tablet core contains budesonide with polymers that provide for extended release of budesonide. Each tablet contains the following inactive ingredients: stearic acid, lecithin, microcrystalline cellulose, hydroxypropyl cellulose, lactose, silicon dioxide, magnesium stearate, methacrylic acid copolymer types A and B, talc, triethyl citrate, and titanium dioxide. uceris-1.jpg

10 OVERDOSAGE Reports of acute toxicity and/or death following overdosage of glucocorticosteroids are rare. Treatment consists of immediate gastric lavage or emesis followed by supportive and symptomatic therapy. If glucocorticosteroids are used at excessive doses for prolonged periods, systemic glucocorticosteroid effects, such as hypercorticism and adrenal suppression may occur. For chronic overdosage in the face of severe disease requiring continuous steroid therapy, the dosage may be reduced temporarily. Single oral budesonide doses of 200 and 400 mg/kg were lethal in female and male mice, respectively. The signs of acute toxicity were decreased motor activity, piloerection and generalized edema.
