Betamethasone 0.1% + Neomycin Sulphate 0.5% E/E prep is a combination preparation used for the treatment of bacterial eye or ear infections. It prevents the growth of bacteria and reduces inflammation.
Description
Betamethasone 0.1% + Neomycin Sulphate 0.5% E/E prep is a combination of two medicines: Betamethasone (a corticosteroid) and Neomycin Sulphate (an antibiotic). Betamethasone is a steroid which blocks the production of certain chemical messengers that make the eye/ear red, swollen and itchy. Neomycin is an antibiotic that stops bacterial growth in the eye/ear by preventing the synthesis of essential proteins required by bacteria.
Eye drops: 1 drop every 1-2 hours until control is achieved, then frequency may be reduced. Ear drops: 2-3 drops every 2-3 hours until control is achieved. Nose drops: 2-3 drops in each nostril 2-3 times daily. Eye ointment: Applied thinly to the conjunctival sac at night or 3-4 times daily if used alone.
Indications
- Bacterial eye infections
- Bacterial ear infections
- Inflammatory eye/ear conditions
Therapeutic class
Ophthalmic & Otic Antibiotic Combination
Pharmacological class
Corticosteroid + Aminoglycoside Antibiotic
Pharmacology
Betamethasone is a corticosteroid which is effective in inflammatory conditions. Neomycin sulfate is a broad spectrum antibiotic. It is bactericidal against many bacteria.
Betamethasone controls inflammation by controlling the rate of protein synthesis, depressing the migration of polymorphonuclear leukocytes and fibroblasts, and reversing capillary permeability and lysosomal stabilisation. Neomycin binds to the 30S ribosomal subunit of bacteria, inhibiting protein synthesis.
Mechanism of action
Betamethasone reduces inflammation and itching, while Neomycin stops bacterial growth by inhibiting protein synthesis. Together, they provide effective treatment for bacterial eye and ear infections.
Dosage
Eye Drops: 1 drop every 1-2 hours until control is achieved, then frequency may be reduced.
Ear Drops: 2-3 drops every 2-3 hours until control is achieved, then frequency may be reduced.
Nose Drops: 2-3 drops in each nostril 2-3 times daily.
Eye Ointment: Apply thinly and evenly to the conjunctival sac at night (if eye drops used during day) or 3-4 times daily (if ointment used alone).
Administration
For external use only. Use in the dose and duration as advised by your doctor. Check the label for directions before use. Hold the dropper close to the eye/ear without touching it. Gently squeeze the dropper and place the medicine inside the lower eyelid or ear. Wipe off extra liquid. Do not touch the dropper tip.
