Description
Overview of the medicine
Betnozen-N Cream is used to treat various inflammatory skin conditions that are complicated by secondary bacterial infections or where there is a risk of such infections. It contains a potent corticosteroid (Betamethasone) to reduce inflammation and an aminoglycoside antibiotic (Neomycin) to combat bacterial growth.
Uses & Indications
Dosage
Adults
Apply a thin film to the affected skin area once or twice daily. Continue for not more than 7 days without medical review. Use cautiously on the face.
Elderly
Same as adults, but caution should be exercised due to potentially thinner skin and increased systemic absorption.
Renal_impairment
No specific dosage adjustment required for topical use, but prolonged or extensive use should be monitored due to potential systemic absorption of Neomycin.
How to Take
For external use only. Apply a thin layer to the affected area and rub in gently. Wash hands before and after application. Avoid contact with eyes and mucous membranes. Do not use under occlusive dressings unless advised by a doctor.
Mechanism of Action
Betamethasone, a potent corticosteroid, acts by inducing phospholipase A2 inhibitory proteins (lipocortins), thereby inhibiting the release of arachidonic acid. This leads to the suppression of various inflammatory mediators like prostaglandins and leukotrienes. Neomycin, an aminoglycoside antibiotic, binds to the 30S ribosomal subunit of susceptible bacteria, thereby inhibiting bacterial protein synthesis and leading to bacterial cell death.
Pharmacokinetics
Onset
Anti-inflammatory effects typically within hours to days of topical application.
Excretion
Excreted mainly by the kidneys; some via bile.
Half life
Not well defined for topical use; systemically, corticosteroids have varying half-lives (e.g., betamethasone approx 3-5 hours).
Absorption
Minimal systemic absorption through intact skin. Absorption increases with inflammation, occlusion, and prolonged use, especially in large areas or broken skin.
Metabolism
Primarily metabolized in the liver, with inactive metabolites.
Side Effects
Contraindications
- •Hypersensitivity to Betamethasone, Neomycin, or any component of the cream
- •Viral skin infections (e.g., herpes simplex, varicella)
- •Fungal skin infections
- •Tuberculosis of the skin
- •Acne rosacea
- •Perioral dermatitis
- •Ulcerative conditions
- •Vaccination reactions
Drug Interactions
Systemic effects
No significant drug interactions are expected with topical Betamethasone/Neomycin due to minimal systemic absorption. However, if used extensively or on damaged skin, systemic absorption of Neomycin could potentially interact with other nephrotoxic or ototoxic drugs (e.g., other aminoglycosides, furosemide).
Storage
Store below 30°C in a cool, dry place. Protect from light and moisture. Do not freeze. Keep out of reach of children.
Overdose
Topical overdose is unlikely to cause acute systemic effects. Chronic overdose or misuse can lead to local skin atrophy, striae, telangiectasias, or systemic corticosteroid effects (e.g., Cushing's syndrome) and, rarely, neomycin systemic toxicity if applied to large areas of broken skin.
Pregnancy & Lactation
Use during pregnancy only if the potential benefit justifies the potential risk to the fetus, and preferably avoid during the first trimester. For lactation, use with caution; minimal systemic absorption suggests low risk, but avoid applying to breasts.
