Educational reference. Always consult a doctor for diagnosis.
🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine contains gentamicin, an aminoglycoside antibiotic that works by binding to the bacterial 30S ribosomal subunit. This binding interferes with protein synthesis, leading to the production of faulty proteins and ultimately causing bacterial cell death. Gentamicin is effective against many gram-negative bacteria and some gram-positive bacteria. It is bactericidal, meaning it kills bacteria directly.
Mechanism Steps
💡 How to Take unigenta eye/ear drops
Strength: Gentamicin 15 mg per mL (0.3% w/v) in a sterile ophthalmic/otic solution.
Dosage Information
| Adult Dosage | For ophthalmic use: Instill 1 to 2 drops into the affected eye(s) every 4 hours, or as directed by your doctor. For severe infections, your doctor may recommend more frequent dosing. For otic use: Instill 2 to 3 drops into the affected ear(s) 3 to 4 times daily, or as directed. The dose and duration must be individualized by a qualified clinician based on the type and severity of infection, age, weight, renal and hepatic function, and clinical response. Do not use for longer than prescribed. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children. |
| Elderly Dosage | Elderly patients may be more susceptible to the toxic effects of aminoglycosides, especially if they have reduced kidney function. Use with caution and monitor kidney function if systemic absorption is possible. Dose must be individualized by a qualified clinician. |
| Renal Impairment | No dosage adjustment is typically required for topical ophthalmic or otic use because systemic absorption is minimal. However, if the medicine is used on large areas of damaged skin or mucosa, systemic absorption may occur, and dose adjustment may be necessary in patients with renal impairment. Consult your doctor. |
| Hepatic Impairment | No dosage adjustment is typically required for topical ophthalmic or otic use because systemic absorption is minimal. Consult your doctor if you have severe liver disease. |
| Maximum Daily Dose | The maximum daily dose for topical ophthalmic or otic use is not established from available information. Use only as prescribed by your doctor. |
