Budesonide, USP, the active ingredient of budesonide capsules (enteric coated), is a synthetic corticosteroid. It 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 molecular formula of budesonide is C25H34O6 and its molecular weight is 430.5 g/mole. Its structural formula is:
Budesonide is a white or almost white crystalline powder that is freely soluble in methylene chloride, sparingly soluble in alcohol and practically insoluble in water. Its partition coefficient between octanol and water at pH 5 is 1.6 x 103 ionic strength 0.01.
Each capsule contains 3 mg of micronized budesonide with the following inactive ingredients: acetyltributyl citrate, colloidal silicon dioxide, crospovidone, dimethicone, ethylcellulose, FD&C Red No. 40, gelatin, lactose monohydrate, magnesium stearate, methacrylic acid copolymer, polysorbate 80, sodium hydroxide, sodium lauryl sulfate, talc, titanium dioxide and triethyl citrate.
The imprinting ink contains the following: black iron oxide, D&C Yellow No. 10 Aluminum Lake, FD&C Blue No. 1 Aluminum Lake, FD&C Blue No. 2 Aluminum Lake, FD&C Red No. 40 Aluminum Lake, propylene glycol and shellac glaze.
Budesonide has a high topical glucocorticosteroid (GCS) activity and a substantial first pass elimination. The formulation contains granules which are coated to protect dissolution in gastric juice, but which dissolve at pH > 5.5, i.e., normally when the granules reach the duodenum. Thereafter, a matrix of ethylcellulose with budesonide controls the release of the drug into the intestinal lumen in a time-dependent manner.
The absorption of budesonide capsules (enteric coated) seems to be complete, although Cmax and Tmax are variable. Time to peak concentration varies in individual patients between 30 and 600 minutes. Following oral administration of 9 mg of budesonide in healthy subjects, a peak plasma concentration of approximately 5 nmol/L is observed and the area under the plasma concentration time curve is approximately 30 nmol•hr/L. The systemic availability after a single dose is higher in patients with Crohn's disease compared to healthy volunteers, (21% vs. 9%) but approaches that in healthy volunteers after repeated dosing.
The mean volume of distribution (Vss) of budesonide varies between 2.2 and 3.9 L/kg in healthy subjects and in patients. Plasma protein binding is estimated to be 85% to 90% in the concentration range 1 to 230 nmol/L, independent of gender. The erythrocyte/plasma partition ratio at clinically relevant concentrations is about 0.8.
Following absorption, budesonide is subject to high first pass metabolism (80% to 90%). In vitro experiments in human liver microsomes demonstrate that budesonide is rapidly and extensively biotransformed, mainly by CYP3A4, to its two major metabolites, 6β-hydroxy budesonide and 16α-hydroxy prednisolone. The glucocorticoid activity of these metabolites is negligible (< 1/100) in relation to that of the parent compound.
In vivo investigations with intravenous doses in healthy subjects are in agreement with the in vitro findings and demonstrate that budesonide has a high plasma clearance, 0.9 to 1.8 L/min. Similarly, high plasma clearance values have been shown in patients with Crohn’s disease. These high plasma clearance values approach the estimated liver blood flow, and, accordingly, suggest that budesonide is a high hepatic clearance drug.
The plasma elimination half-life, t1/2, after administration of intravenous doses ranges between 2 and 3.6 hours, and does not differ between healthy adults and patients with Crohn’s disease.
Budesonide is excreted in urine and feces in the form of metabolites. After oral as well as intravenous administration of micronized [3H]-budesonide, approximately 60% of the recovered radioactivity is found in urine. The major metabolites, including 6β-hydroxy budesonide and 16α-hydroxy prednisolone, are mainly renally excreted, intact or in conjugated forms. No unchanged budesonide is detected in urine.
In patients with liver cirrhosis, systemic availability of orally administered budesonide correlates with disease severity and is, on average, 2.5-fold higher compared with healthy controls. Patients with mild liver disease are minimally affected. Patients with severe liver dysfunction were not studied. Absorption parameters are not altered, and for the intravenous dose, no significant differences in CL or Vss are observed.
The pharmacokinetics of budesonide in patients with renal impairment has not been studied. Intact budesonide is not renally excreted, but metabolites are to a large extent, and might therefore reach higher levels in patients with impaired renal function. However, these metabolites have negligible corticosteroid activity as compared with budesonide (< 1/100). Thus, patients with impaired renal function taking budesonide are not expected to have an increased risk of adverse effects.
Budesonide is metabolized via CYP3A4. Potent inhibitors of CYP3A4 can increase the plasma levels of budesonide severalfold. Coadministration of ketoconazole results in an 8-fold increase in AUC of budesonide, compared to budesonide alone. Grapefruit juice, an inhibitor of gut mucosal CYP3A, approximately doubles the systemic exposure of oral budesonide. Conversely, induction of CYP3A4 can result in the lowering of budesonide plasma levels. Oral contraceptives containing ethinyl estradiol, which are also metabolized by CYP3A4, do not affect the pharmacokinetics of budesonide. Budesonide does not affect the plasma levels of oral contraceptives (i.e., ethinyl estradiol).
Since the dissolution of the coating of budesonide capsules (enteric coated) is pH dependent (dissolves at pH > 5.5), the release properties and uptake of the compound may be altered after treatment with drugs that change the gastrointestinal pH. However, the gastric acid inhibitory drug omeprazole, 20 mg qd, does not affect the absorption or pharmacokinetics of budesonide capsules (enteric coated). When an uncoated oral formulation of budesonide is coadministered with a daily dose of cimetidine 1 g, a slight increase in the budesonide peak plasma concentration and rate of absorption occurs, resulting in significant cortisol suppression.
A mean delay in time to peak concentration of 2.5 hours is observed with the intake of a high-fat meal, with no significant differences in AUC.
Budesonide has a high glucocorticoid effect and a weak mineralocorticoid effect, and the affinity of budesonide to GCS receptors, which reflects the intrinsic potency of the drug, is about 200-fold that of cortisol and 15-fold that of prednisolone.
Treatment with systemically active GCS is associated with a suppression of endogenous cortisol concentrations and an impairment of the hypothalamus-pituitary-adrenal (HPA) axis function. Markers, indirect and direct, of this are cortisol levels in plasma or urine and response to ACTH stimulation.
Plasma cortisol suppression was compared following 5 days’ administration of budesonide capsules (enteric coated) and prednisolone in a crossover study in healthy volunteers. The mean decrease in the integrated 0 to 24 hour plasma cortisol concentration was greater (78%) with prednisolone 20 mg/day compared to 45% with budesonide capsules (enteric coated) 9 mg/day.
The safety and efficacy of budesonide capsules (enteric coated) were evaluated in 994 patients with mild to moderate active Crohn’s disease of the ileum and/or ascending colon in five randomized and double-blind studies. The study patients ranged in age from 17 to 85 (mean 35), 40% were male and 97% were white. Of the 651 patients treated with budesonide capsules (enteric coated), 17 (2.6%) were ≥ 65 years of age and none were > 74 years of age. The Crohn’s Disease Activity Index (CDAI) was the main clinical assessment used for determining efficacy in these five studies. The CDAI is a validated index based on subjective aspects rated by the patient (frequency of liquid or very soft stools, abdominal pain rating and general wellbeing) and objective observations (number of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal mass, body weight and hematocrit). Clinical improvement, defined as a CDAI score of ≤ 150 assessed after 8 weeks of treatment, was the primary efficacy variable in these five comparative efficacy studies of budesonide capsules (enteric coated). Safety assessments in these studies included monitoring of adverse experiences. A checklist of potential symptoms of hypercorticism was used.
One study (Study 1) compared the safety and efficacy of budesonide capsules (enteric coated) 9 mg qd in the morning to a comparator. At baseline, the median CDAI was 272. Budesonide capsules (enteric coated) 9 mg qd resulted in a significantly higher clinical improvement rate at Week 8 than the comparator (Table 1).
Two placebo-controlled clinical trials (Studies 2 and 3) were conducted. Study 2 involved 258 patients and tested the effects of graded doses of budesonide capsules (enteric coated) (1.5 mg bid, 4.5 mg bid, or 7.5 mg bid) versus placebo. At baseline, the median CDAI was 290. The 3 mg per day dose level (data not shown) could not be differentiated from placebo. The 9 mg per day arm was statistically different from placebo (Table 1), while no additional benefit was seen when the daily budesonide capsules (enteric coated) dose was increased to 15 mg per day (data not shown). In Study 3, the median CDAI at baseline was 263. Neither 9 mg qd nor 4.5 mg bid budesonide capsules (enteric coated) dose levels was statistically different from placebo (Table 1).
Two clinical trials (Studies 4 and 5) compared budesonide capsules (enteric coated) with oral prednisolone (initial dose 40 mg per day). At baseline, the median CDAI was 277. Equal clinical improvement rates (60%) were seen in the budesonide capsules (enteric coated) 9 mg qd and the prednisolone groups in Study 4. In Study 5, 13% fewer patients in the budesonide capsules (enteric coated) group experienced clinical improvement than in the prednisolone group (no statistical difference) (Table 1).
The proportion of patients with normal plasma cortisol values (≥ 150 nmol/L) was significantly higher in the budesonide capsules (enteric coated) groups in both trials (60% to 66%) than in the prednisolone groups (26% to 28%) at Week 8.
The efficacy and safety of budesonide capsules (enteric coated) for maintenance of clinical remission were evaluated in four double-blind, placebo-controlled, 12-month trials in which 380 patients were randomized and treated once daily with 3 mg or 6 mg budesonide capsules (enteric coated) or placebo. Patients ranged in age from 18 to 73 (mean 37) years. Sixty percent of the patients were female and 99% were Caucasian. The mean CDAI at entry was 96. Among the four clinical trials, approximately 75% of the patients enrolled had exclusively ileal disease. Colonoscopy was not performed following treatment. Budesonide capsules (enteric coated) 6 mg/day prolonged the time to relapse, defined as an increase in CDAI of at least 60 units to a total score > 150 or withdrawal due to disease deterioration. The median time to relapse in the pooled population of the four studies was 154 days for patients taking placebo, and 268 days for patients taking budesonide capsules (enteric coated) 6 mg/day. Budesonide capsules (enteric coated) 6 mg/day reduced the proportion of patients with loss of symptom control relative to placebo in the pooled population for the four studies at 3 months (28% vs. 45% for placebo).
INDICATIONS AND USAGE
Budesonide capsules (enteric coated) are indicated for:
Budesonide capsules (enteric coated) are contraindicated in patients with known hypersensitivity to budesonide.
Glucocorticosteroids can reduce the response of the hypothalamus-pituitary-adrenal (HPA) axis to stress. In situations where patients are subject to surgery or other stress situations, supplementation with a systemic glucocorticosteroid is recommended. Since budesonide capsules (enteric coated) are a glucocorticosteroid, general warnings concerning glucocorticoids should be followed.
Care is needed in patients who are transferred from glucocorticosteroid treatment with high systemic effects to corticosteroids with lower systemic availability, since symptoms attributed to withdrawal of steroid therapy, including those of acute adrenal suppression or benign intracranial hypertension, may develop. Adrenocortical function monitoring may be required in these patients and the dose of systemic steroid should be reduced cautiously.
Patients who are on drugs that suppress the immune system are more susceptible to infection than healthy individuals. Chicken pox and measles, for example, can have a more serious or even fatal course in susceptible patients or patients on immunosuppressant doses of glucocorticosteroids. In patients who have not had these diseases, particular care should be taken to avoid exposure. How the dose, route and duration of glucocorticosteroid administration affect the risk of developing a disseminated infection is not known. The contribution of the underlying disease and/or prior glucocorticosteroid treatment to the risk is also not known. If exposed, therapy with varicella zoster immune globulin (VZIG) or pooled intravenous immunoglobulin (IVIG), as appropriate, may be indicated. If exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated. (See the respective package insert for complete VZIG and IG prescribing information.) If chicken pox develops, treatment with antiviral agents may be considered.
Caution should be taken in patients with tuberculosis, hypertension, diabetes mellitus, osteoporosis, peptic ulcer, glaucoma or cataracts, or with a family history of diabetes or glaucoma, or with any other condition where glucocorticosteroids may have unwanted effects.
Replacement of systemic glucocorticosteroids with budesonide capsules (enteric coated) may unmask allergies, e.g., rhinitis and eczema, which were previously controlled by the systemic drug.
When budesonide capsules (enteric coated) are used chronically, systemic glucocorticosteroid effects such as hypercorticism and adrenal suppression may occur.
Reduced liver function affects the elimination of glucocorticosteroids, and increased systemic availability of oral budesonide has been demonstrated in patients with liver cirrhosis.
Information for Patients
Budesonide capsules (enteric coated) should be swallowed whole and NOT CHEWED OR BROKEN.
Patients should be advised to avoid the consumption of grapefruit juice for the duration of their budesonide capsules (enteric coated) therapy.
Patients should be given the patient package insert for additional information.
Concomitant oral administration of ketoconazole (a known inhibitor of CYP3A4 activity in the liver and in the intestinal mucosa) caused an 8-fold increase of the systemic exposure to oral budesonide. If treatment with inhibitors of CYP3A4 activity (such as ketoconazole, itraconazole, ritonavir, indinavir, saquinavir, erythromycin, etc.) is indicated, reduction of the budesonide dose 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 2 times. As with other drugs primarily being metabolized through CYP3A4, ingestion of grapefruit or grapefruit juice should be avoided in connection with budesonide administration.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenicity studies with budesonide were conducted in rats and mice. In a 2-year study in Sprague-Dawley rats, budesonide caused a statistically significant increase in the incidence of gliomas in male rats at an oral dose of 50 mcg/kg (approximately 0.05 times the maximum recommended human dose on a body surface area basis). In addition, there were increased incidences of primary hepatocellular tumors in male rats at 25 mcg/kg (approximately 0.023 times the maximum recommended human dose on a body surface area basis) and above. No tumorigenicity was seen in female rats at oral doses up to 50 mcg/kg (approximately 0.05 times the maximum recommended human dose on a body surface area basis). In an additional 2-year study in male Sprague-Dawley rats, budesonide caused no gliomas at an oral dose of 50 mcg/kg (approximately 0.05 times the maximum recommended human dose on a body surface area basis). However, it caused a statistically significant increase in the incidence of hepatocellular tumors at an oral dose of 50 mcg/kg (approximately 0.05 times the maximum recommended human dose on a body surface area basis). The concurrent reference corticosteroids (prednisolone and triamcinolone acetonide) showed similar findings. In a 91-week study in mice, budesonide caused no treatment-related carcinogenicity at oral doses up to 200 mcg/kg (approximately 0.1 times the maximum recommended human dose on a body surface area basis).
Budesonide was not genotoxic in the Ames test, the mouse lymphoma cell forward gene mutation (TK+/-) test, the human lymphocyte chromosome aberration test, the Drosophila melanogaster sex-linked recessive lethality test, the rat hepatocycte UDS test and the mouse micronucleus test.
In rats, budesonide had no effect on fertility at subcutaneous doses up to 80 mcg/kg (approximately 0.07 times the maximum recommended human dose on a body surface area basis). However, it caused a decrease in prenatal viability and viability in pups at birth and during lactation, along with a decrease in maternal body-weight gain, at subcutaneous doses of 20 mcg/kg (approximately 0.02 times the maximum recommended human dose on a body surface area basis) and above. No such effects were noted at 5 mcg/kg (approximately 0.005 times the maximum recommended human dose on a body surface area basis).
Teratogenic Effects. Pregnancy Category C
As with other corticosteroids, budesonide was teratogenic and embryocidal in rabbits and rats. Budesonide produced fetal loss, decreased pup weights, and skeletal abnormalities at subcutaneous doses of 25 mcg/kg in rabbits (approximately 0.05 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).
There are no adequate and well controlled studies in pregnant women. Budesonide should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
The disposition of budesonide when delivered by inhalation from a dry powder inhaler at doses of 200 mcg or 400 mcg twice daily for at least 3 months was studied in eight lactating women with asthma from 1 to 6 months postpartum1. Systemic exposure to budesonide in these women appears to be comparable to that in non-lactating women with asthma from other studies. Breast milk obtained over 8 hours post-dose revealed that the maximum budesonide concentration for the 400 mcg and 800 mcg total daily doses was 0.39 and 0.78 nmol/L, respectively, and occurred within 45 minutes after inhalation. The estimated oral daily dose of budesonide from breast milk to the infant is approximately 0.007 and 0.014 mcg/kg/day for the two dose regimens used in this study, which represents approximately 0.3% to 1% of the dose inhaled by the mother. Budesonide plasma concentrations obtained from five infants at about 90 minutes after breast-feeding (and about 140 minutes after drug administration to the mother) were below quantifiable levels (< 0.02 nmol/L in four infants and < 0.04 nmol/L in one infant).
The recommended daily dose of budesonide capsules (enteric coated) is higher (up to 9 mg daily) compared with inhaled budesonide (up to 800 mcg daily) given to mothers in the above study. The maximum budesonide plasma concentration following a 9 mg daily dose (in both single- and repeated-dose pharmacokinetic studies) of oral budesonide approximately 5 to 10 nmol/L which is up to 10 times higher than the 1 to 2 nmol/L for a 800 mcg daily dose of inhaled budesonide at steady-state in the above inhalation study.
Since there are no data from controlled trials on the use of budesonide capsules (enteric coated) by nursing mothers or their infants, and because of the potential for serious adverse reactions in nursing infants from budesonide capsules (enteric coated), a decision should be made whether to discontinue nursing or to discontinue budesonide capsules (enteric coated), taking into account the clinical importance of budesonide capsules (enteric coated) to the mother.
Budesonide, like other corticosteroids, is secreted in human milk. Data from budesonide delivered via dry powder inhaler indicates that the total daily oral dose of budesonide available in breast milk to the infant is approximately 0.3% to 1% of the dose inhaled by the mother. Assuming the coefficient of extrapolation between the inhaled and oral doses is constant across all dose levels, at therapeutic doses of budesonide capsules (enteric coated), budesonide exposure to the nursing child may be up to 10 times higher than that by budesonide inhalation.
Clinical studies of budesonide capsules (enteric coated) did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of budesonide capsules (enteric coated) was evaluated in 651 patients in five short-term, active disease state studies. They ranged in age from 17 to 74 (mean 35), 40% were male and 97% were white, 2.6% were ≥ 65 years of age. Five hundred and twenty patients were treated with budesonide capsules (enteric coated) 9 mg (total daily dose). In general, budesonide capsules (enteric coated) were well tolerated in these trials. The most common adverse events reported were headache, respiratory infection, nausea, and symptoms of hypercorticism. Clinical studies have shown that the frequency of glucocorticosteroid-associated adverse events was substantially reduced with budesonide capsules (enteric coated) compared with prednisolone at therapeutically equivalent doses. Adverse events occurring in ≥ 5% of the patients are listed in Table 2:
The safety of budesonide capsules (enteric coated) was evaluated in 233 patients in four long-term clinical trials (52 weeks). A total of 145 patients were treated with budesonide capsules (enteric coated) 6 mg. A total of 8% of budesonide capsules (enteric coated) patients discontinued treatment due to adverse events compared with 10% in the placebo group. The adverse event profile in long-term treatment of Crohn’s disease was similar to that of short-term treatment with budesonide capsules (enteric coated) 9 mg in active Crohn’s disease.
In the long-term clinical trials, the following adverse events occurred in ≥ 5% of the 6 mg budesonide capsules (enteric coated) patients and are not listed in Table 2 or by body system below: diarrhea (10%); sinusitis (8%); infection viral (6%); and arthralgia (5%).
Adverse events, occurring in 520 patients treated with budesonide capsules (enteric coated) 9 mg (total daily dose) in short-term active disease state studies, with an incidence of < 5% and greater than placebo (n = 107) are listed below by body system:
Body as a Whole: asthenia, C-Reactive protein increased, chest pain, dependent edema, face edema, flu-like disorder, malaise; Cardiovascular: hypertension; Central and Peripheral Nervous System: hyperkinesia, paresthesia, tremor, vertigo; Gastrointestinal: anus disorder, Crohn’s disease aggravated, enteritis, epigastric pain, gastrointestinal fistula, glossitis, hemorrhoids, intestinal obstruction, tongue edema, tooth disorder; Hearing and Vestibular: Ear infection-not otherwise specified; Heart Rate and Rhythm: palpitation, tachycardia; Metabolic and Nutritional: hypokalemia, weight increase; Musculoskeletal: arthritis aggravated, cramps, myalgia; Psychiatric: agitation, appetite increased, confusion, insomnia, nervousness, sleep disorder, somnolence; Resistance Mechanism: moniliasis; Reproductive, Female: intermenstrual bleeding, menstrual disorder; Respiratory: bronchitis, dyspnea; Skin and Appendages: acne, alopecia, dermatitis, eczema, skin disorder, sweating increased; Urinary: dysuria, micturition frequency, nocturia; Vascular: flushing; Vision: eye abnormality, vision abnormal; White Blood Cell: leukocytosis
For the 145 patients treated with budesonide capsules (enteric coated) 6 mg (total daily dose) in long-term studies, the following adverse events that are not included in the list above occurred with an incidence < 5% but > 2% and greater than for placebo: abscess, amnesia, dizziness, fever, pharynx disorder, purpura, rhinitis, and urinary tract infection.
Glucocorticosteroid Adverse Reactions
Table 3 displays the frequency and incidence of signs/symptoms of hypercorticism by active questioning of patients in short-term clinical trials.
Table 4 displays the frequency and incidence of signs/symptoms of hypercorticism by active questioning of patients in long-term clinical trials.
The incidence of signs/symptoms of hypercorticism as described above in long-term clinical trials was similar to that seen in the short-term clinical trials.
A randomized, open, parallel-group multicenter safety study specifically compared the effect of budesonide capsules (enteric coated) (< 9 mg/day) and prednisolone (< 40 mg/day) on bone mineral density over 2 years when used at doses adjusted to disease severity. Bone mineral density decreased significantly less with budesonide capsules (enteric coated) than with prednisolone in steroid-naïve patients, whereas no difference could be detected between treatment groups for steroid-dependent patients and previous steroid users. The incidence of treatment-emergent symptoms of hypercorticism was significantly higher with prednisolone treatment.
The following adverse reactions have been identified during postapproval use of budesonide capsules (enteric coated). Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Immune System Disorders: Anaphylactic reactions; Nervous System Disorders: Benign intracranial hypertension.
CLINICAL LABORATORY TEST FINDINGS
The following potentially clinically significant laboratory changes in clinical trials, irrespective of relationship to budesonide capsules (enteric coated), were reported in ≥ 1% of patients: hypokalemia, leukocytosis, anemia, hematuria, pyuria, erythrocyte sedimentation rate increased, alkaline phosphatase increased, atypical neutrophils, C-reactive protein increased, and adrenal insufficiency.
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 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.
DOSAGE AND ADMINISTRATION
The recommended adult dosage for the treatment of mild to moderate active Crohn's disease involving the ileum and/or the ascending colon is 9 mg taken once daily in the morning for up to 8 weeks. Repeated 8-week courses of budesonide capsules (enteric coated) can be given for recurring episodes of active disease.
Following an 8-week course(s) of treatment for active disease and once the patient’s symptoms are controlled (CDAI < 150), budesonide capsules (enteric coated) 6 mg is recommended once daily for maintenance of clinical remission up to 3 months. If symptom control is still maintained at 3 months an attempt to taper to complete cessation is recommended. Continued treatment with budesonide capsules (enteric coated) 6 mg for more than 3 months has not been shown to provide substantial clinical benefit.
Patients with mild to moderate active Crohn’s disease involving the ileum and/or ascending colon have been switched from oral prednisolone to budesonide capsules (enteric coated) with no reported episodes of adrenal insufficiency. Since prednisolone should not be stopped abruptly, tapering should begin concomitantly with initiating budesonide capsules (enteric coated) treatment.
Patients with moderate to severe liver disease should be monitored for increased signs and/or symptoms of hypercorticism. Reducing the dose of budesonide capsules (enteric coated) should be considered in these patients.
If concomitant administration with ketoconazole, or any other CYP3A4 inhibitor, is indicated, patients should be closely monitored for increased signs and/or symptoms of hypercorticism. Reduction in the dose of budesonide capsules (enteric coated) should be considered.
Budesonide capsules (enteric coated) should be swallowed whole and not chewed or broken.
Budesonide Capsules (enteric coated) are available as 3 mg capsules.
The 3 mg capsule is a red opaque cap/red opaque body, hard-shell gelatin capsule filled with white to off-white enteric-coated pellets with no markings. The capsule is axially printed with MYLAN over 7155 in black ink on both the cap and body. They are available as follows:
