Budesonide is a synthetic corticosteroid having potent glucocorticoid activity and weak mineralocorticoid activity. It has approximately a 200-fold higher affinity for the glucocorticoid receptor and a 1000-fold higher topical anti-inflammatory potency than cortisol. Corticosteroids have been shown to have a wide range of inhibitory activities against multiple cell types (e.g., mast cell, eosinophil, neutrophil, macrophage, and lymphocyte) and mediators (e.g., histamine, eicosanoids, leukotriene, and cytokine) involved in allergic mediated inflammation.

Budesonide is a glucocorticoid used to treat respiratory and digestive conditions by reducing inflammation. It has a wide therapeutic index, as dosing varies highly from patient to patient. Patients should be counselled regarding the risk of hypercorticism and adrenal axis suppression.

Uses

Budesonide is a glucocorticoid used for the induction of remission in patients with active, mild to moderate ulcerative colitis.

Budesonide Nebuliser suspension is used for the maintenance treatment and as prophylactic therapy of asthma.

Budesonide Nasal Spray is used for-

Prophylaxis and treatment of seasonal and perennial allergic rhinitis
Prophylaxis and treatment of vasomotor rhinitis
Symptomatic relief of nasal polyposis
Prevention against nasal polyps after polypectomy

Budesonide Inhaler is used for the maintenance treatment of asthma as prophylactic therapy in adult and paediatric patients six years of age or older. It is also used for patients requiring oral corticosteroid therapy for asthma, many of those patients may be able to reduce or eliminate their requirement for oral corticosteroids over time. Budesonide inhaler is not used for the relief of acute bronchospasm.

bufomix is also used to associated treatment for these conditions: Allergic Rhinitis (AR), Allergies, Asthma, Chronic Obstructive Pulmonary Disease (COPD), Collagenous Colitis, Crohn's Disease (CD), Nasal Congestion, Oesophagitis, Eosinophilic, Polyps, Nasal, Pruritus, Rhinosinusitis, Ulcerative Colitis, Vasomotor Rhinitis, Corticosteroid-responsive dermatoses, Mild Crohn’s Disease, Moderate Crohn’s Disease

How bufomix works

The short term effects of corticosteroids are decreased vasodilation and permeability of capillaries, as well as decreased leukocyte migration to sites of inflammation. Corticosteroids binding to the glucocorticoid receptor mediates changes in gene expression that lead to multiple downstream effects over hours to days.

Glucocorticoids inhibit neutrophil apoptosis and demargination; they inhibit phospholipase A2, which decreases the formation of arachidonic acid derivatives; they inhibit NF-Kappa B and other inflammatory transcription factors; they promote anti-inflammatory genes like interleukin-10.

Lower doses of corticosteroids provide an anti-inflammatory effect, while higher doses are immunosuppressive. High doses of glucocorticoids for an extended period bind to the mineralocorticoid receptor, raising sodium levels and decreasing potassium levels.

Dosage

bufomix dosage

Children 3 months to 12 years of age: 0.5 - 1 mg twice daily.Adults and elderly: 1 - 2 mg twice daily.

Side Effects

●headache● nausea● upper abdominal pain● fatigue● acne● flatulence● joint pain● urinary tract infection● abdominal distension● constipation

Toxicity

Acute overdose of corticosteroids is rare, however prolonged high dosing of corticosteroids can lead to hypercorticism and adrenal axis suppression. In the case of overdose, reduce the dosage of corticosteroids temporarily.

A 200mg oral dose is lethal to female mice while a 400mg oral dose is lethal to male mice.

Precaution

● Since budesonide is a glucocorticoid, general warnings concerning glucocorticoids should be followed.

● Risk of impaired adrenal function when transferring from glucocorticoid treatment with higher systemiceffects to glucocorticoid treatment with lower systemic effects, such as budesonide. Taper patients slowly fromsystemic corticosteroids if transferring to budesonide.

● Potential worsening of infections (e.g., chickenpox, measles, existing tuberculosis, fungal, bacterial, viral, orparasitic infection). Use with caution in patients with these infections.

● Reduced liver function affects the elimination of glucocorticoid, and increases systemic availability of oralbudesonide.

Interaction

Avoid Cytochrome P450 3A4 inhibitors (e.g. ketoconazole, grapefruit juice). It may cause increased systemic corticosteroid effects. Budesonide does not affect the plasma levels of oral contraceptives.

Volume of Distribution

The volume of distribution of budesonide is 2.2-3.9L/kg.

Elimination Route

Extended release oral capsules are 9-21% bioavailable. A 9mg dose reaches a C_max of 1.50±0.79ng/mL with a T_max of 2-8h and an AUC of 7.33ng*hr/mL. A high fat meal increases the T_max by 2.3h but otherwise does not affect the pharmacokinetics of budesonide.

180-360µg metered inhaled doses of budesonide are 34% deposited in the lungs, 39% bioavailable, and reach a C_max of 0.6-1.6nmol/L with a T_max of 10 minutes.

A 1mg nebulized dose is 6% bioavailable, reaching a C_max of 2.6nmol/L with a T_max of 20 minutes.

A 9mg oral extended release tablet reaches a C_max of 1.35±0.96ng/mL with a T_max of 13.3±5.9h and an AUC of 16.43±10.52ng*hr/mL.

Budesonide rectal foam 2mg twice daily has an AUC of 4.31ng*hr/mL.

Half Life

Budesonide has a plasma elimination half life of 2-3.6h. The terminal elimination half life in asthmatic children 4-6 years old is 2.3h.

Clearance

Budesonide has a plasma clearance of 0.9-1.8L/min. The 22R form has a clearance of 1.4L/min while the 22S form has a clearance of 1.0L/min. The clearance in asthmatic children 4-6 years old is 0.5L/min.

Elimination Route

Approximately 60% of a budesonide dose is recovered in the urine as the major metabolites 6beta-hydroxybudesonide, 16alpha-hydroxyprednisolone, and their conjugates. No unchanged budesonide is recovered in urine.

Pregnancy & Breastfeeding use

Pregnancy Category CThere 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.Nursing mothers

Budesonide is secreted in human milk. So, a decision should be made whether to discontinue nursing or budesonide taking into account the clinical importance of the drug to the mother.

Use in childrenSafety and effectiveness of budesonide in pediatric patients have not been established.Use in Hepatic Impaired patientsMonitor patients for signs and/or symptoms of hypercorticism.

Contraindication

Hypersensitivity to any of the ingredients of Budesonide.

Acute Overdose

If glucocorticoids are used at excessive doses for prolonged periods, systemic glucocorticoid effects such as hypercorticism and adrenal suppression may occur.

Symptoms: Decreased motor activity, piloerection, generalised oedema. Management: Immediate gastric lavage or emesis followed by supportive and symptomatic treatment.
