Budesonide Chemical Properties,Uses,Production

Description

Budesonide (brand name: Pulmicort) is a synthetic corticosteroid medication. It is indicated for the maintenance and prophylactic treatment of asthma. It is also used for the long-term management of chronic obstructive pulmonary disease (COPD). It is also useful for the treatment of inflammatory bowel disease including Crohn’s disease, ulcerative colitis and microscopic colitis, and also for treating allergic rhinitis. It exhibits potent glucocorticoid activity and weak mineralocorticoid activity in vivo. It is effective in inhibiting the activities of multiple cell types and mediators participating in either allergic or non-allergic-mediated inflammation.

indications

Budesonide is a commonly used in the treatment of bronchial asthma clinical drug in China.it can be used for non-hormone-dependent or hormone-dependent asthma, and chronic asthmatic bronchitis. Or it is used for the treatment of seasonal allergic rhinitis and many years occurring allergic rhinitis and it is used for preventing polyps regeneration after the removal of nasal polyps . It can also be used to treat various skin diseases.
Budesonide is a halogen-free, topically applied , adrenal corticosteroid,it has significant anti-inflammatory, anti-allergic, anti-itching and anti-exudative effects. Its local effects is the same as beclomethasone dipropionate , it is mainly used for bronchial asthma which in the past bronchodilator or an antiallergic agent can not well control. This product can relieve bronchial spasm, pulmonary inhalation has anti-inflammatory effects, long-term use is well tolerated, it can reduce oral glucocorticoid dosage, without systemic effects of corticosteroids. It has the same effect on Children and adults with asthma as beclomethasone dipropionate , it has good effect, and it can be tolerated in long-term use ,for glucocorticoid-dependent or glucocorticoid-independent patients, mist inhaled can control asthma attacks and can effectively relapse prevention, inhaled treatment for 3 to 6 months, improvement in lung function is shown,the number of acute episodes is reduced , recoverability of plasma corticosterone concentration is gradually increased, and the daily dose of oral corticosteroids can be reduced by 40% to 50%. Thus,for glucocorticoid-dependent asthma patients, especially in patients with a larger amount of dose,the product can be used as an ideal alternative to thedrug for oral administration. Glucocorticoid effects of budesonide are strong, but mineralocorticoid effects are weak . Animal tests show that the drug’s effects on glucocorticoid receptor affinity are 200 times of cortisone, anti-inflammatory effects when it is applied topically are 1,000 times of cortisone , and subcutaneous and oral anti-inflammatory effects are only 40 and 25 times stronger than cortisone .

Precaution and Inhibition

Take Caution when it is used in tuberculosis, airway fungal infection or viral infection. Avoid pregnancy administration. Oral steroid-dependent patients, should gradually reduce oral steroid dose after 10d use , until it reaches a stable respiratory capacity minimum. In severe stress, the dose of oral steroids should be increased, such as severe infection, trauma, surgery. When sputum thickens and congests the airway , the short-term oral steroid should be supplemented . Fast Reduction of Oral hormone, can cause withdrawal symptoms, such as arthritis, rhinitis, eczema, muscle and joint pain,which should be paid attention to prevent it.
Budesonide can be used for mild asthma, when asthma symptoms are obvious,they should be added with a larger dose of water-soluble corticosteroids or bronchodilators and antihistamines. Aerosol has throat irritation on individual patient , Candida albicans infections may occur , rinse mouth and throat immediately after inhalation which can reduce irritation.

Description

Budesonide is composed of a 1:1 mixture of epimers of the 16,17-butylacetal, creating a chiral center. The 22R-epimer binds to the GR with higher affinity than does the 22S-epimer (Table 33.5). The butyl acetal chain provided the highest potency for the homologous acetal chains. Its rate of topical uptake into epithelial tissue is more than 100 times faster than that for hydrocortisone and dexamethasone. Approximately 85% of the IV administered dose of budesonide undergoes extensive first-pass hepatic metabolism by CYP3A4 to its primary metabolites, 6β-hydroxybudesonide and 16α-hydroxyprednisolone, which have approximately 1/100 the potency of budesonide. This is an important inactivation step in limiting budesonide's systemic effect on adrenal suppression.

Chemical Properties

Uses

A non-halogenated glucocorticoid related to triamcinolone hexacetonide. Used as an antiinflammatory agent

Uses

laxative, antineoplastic

Uses

The oral capsule is used for the treatment of mild to moderate active Crohn's disease. The oral tablet is used for induction of remission in patients with active, mild to moderate ulcerative colitis. The oral inhalation formulation is used for the treatme

Uses

Budesonide is a glucocorticoid steroid that activates the glucorcorticoid receptor with an EC50 value of 12.4 nM. Like other glucocorticoids, budesonide reduces inflammation and has utility in inflammatory diseases, like asthma and inflammatory bowel disease. Also like other glucocorticoids, budesonide may be abused by athletes.[Cayman Chemical]

Definition

ChEBI: A glucocorticoid steroid having a highly oxygenated pregna-1,4-diene structure. It is used mainly in the treatment of asthma and non-infectious rhinitis and for treatment and prevention of nasal polyposis.

Indications

Budesonide is a synthetic corticosteroid having a potent glucocorticoid and weak mineralocorticoid activity. In standard in vitro and animal models, budesonide has an approximately 200-fold higher affinity for the glucocorticoid receptor and a 1000-fold higher topical antiinflammatory potency than cortisol.

brand name

Entocort (AstraZeneca); Pulmicort (AstraZeneca); Rhinocort (AstraZeneca).

General Description

Budesonide (Pulmicort Turbohaler,Rhinocort) is extensively metabolized in the liver, with 85%to 95% of the orally absorbed drug metabolized by the firstpasseffect. The major metabolites are 6β-hydroxybudesonideand 16α-hydroxyprednisolone, both with less than1% of the activity of the parent compound. Metabolism involvesthe CYP3A4 enzyme, so coadministration of budesonidewith a known CYP3A4 inhibitor should be monitoredcarefully.

General Description

Budesonide, 16α,17-[butylidenebis-(oxy)]-11β,21-dihydroxypregna-1,4-diene-3, 20-dione (Entocort), in oral capsules is used to treat Crohn disease. Theaffinity for the GC is approximately 200-fold greater than thatof hydrocortisone and 15-fold greater than that of prednisolone.Budesonide is a mixture of epimers, with the 22Rform having twice the affinity for the GR of the S epimer.This GC is metabolized by CYP3A4, and its levels can be increasedin the presence of potent CYP3A4 inhibitors.Budesonide is also used in an inhaled formulation for thetreatment of asthma.

Biological Activity

Synthetic anti-inflammatory glucocorticoid that displays chemopreventive activity. Prevents formation of lung adenomas and adenocarcinomas in mice following inhalation or oral administration. Reverses DNA hypomethylation and modulates expression of cancer related genes.

Mechanism of action

Budesonide is an acetal formed between the 16α,17α-dihydroxyl groups and butanal. It is a nonhalogenated glucocorticoid with a 16,17-acetal that decreases the mineralocorticoid activity. In receptor affinity studies, the R-epimer was twofold more active than the S-epimer. Because the C-21 hydroxy is free, budesonide is not a prodrug and is active as administered. Only 34% of the metered dose of inhaled budesonide reaches the lung.

Pharmacology

While budesonide is well absorbed from the GI tract, its oral bioavailability is low (about 10%), primarily because of extensive first-pass metabolism in the liver. Two major metabolites (16α-hydroxyprednisolone and 6β- hydroxybudesonide) are formed via the cytochrome P450 3A enzyme. In vitro studies on the binding of the two primary metabolites to the corticosteroid receptor indicate that their affinity for the receptor is less than 1% of that of the parent compound. It is hoped that use of this drug will avoid the long-term adverse reactions seen with systemically active corticosteroids.

Clinical Use

Recently, budesonide (Entecort EC) has been approved for the treatment of mildly to moderately active Crohn’s disease involving the ileum and/or ascending colon.

Veterinary Drugs and Treatments

While there are inhalational forms of the medication for treating asthma or allergic rhinitis, most veterinary interest involves its potential oral use to treat inflammatory intestinal diseases in small animals that are either refractory to, or intolerant of, systemic steroids. In humans, oral budesonide is indicated for Crohn’s disease.

Metabolism

Budesonide was metabolized three- to sixfold more rapidly than triamcinolone acetonide. The pharmacokinetics of budesonide after inhalation, oral, and IV administration displayed a mean plasma half-life of 2.8 hours and a systemic bioavailability of approximately 10% after oral administration (Table 33.5) (101). Pulmonary bioavailability is less than 40% after inhalation (70–75% after correction for the amounts of budesonide deposited in the inhalation device and oral cavity). No oxidative metabolism was observed in the lung. When given by inhalation, 32% of the dose is excreted in the urine as metabolites, 15% in the feces, and 41% of the dose remained in the mouthpiece of the inhaler. Following intranasal administration, very little of intranasal budesonide is absorbed from the nasal mucosa. Much of the intranasal dose (~60%) was swallowed, however, and remained in the GI tract to be excreted unchanged in the feces, whereas that fraction of the intranasal dose that was absorbed was extensively metabolized.
