🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Tobramycin, the active ingredient in this medicine, is an aminoglycoside antibiotic that works by binding to the 30S ribosomal subunit of susceptible bacteria. This binding interferes with protein synthesis, leading to the production of faulty proteins and ultimately causing bacterial cell death. It is effective against a wide range of gram-negative and some gram-positive bacteria.
Mechanism Steps
💡 How to Take optob eye drop
Strength: Ophthalmic solution containing tobramycin 0.3% (3 mg/mL).
Dosage Information
| Adult Dosage | The usual adult dose for bacterial conjunctivitis is 1 to 2 drops in the affected eye(s) every 4 hours. For severe infections, your doctor may recommend 2 drops every hour until improvement, then reduce frequency. 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. Always follow your doctor's prescription. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children. |
| Elderly Dosage | Elderly patients may use this medicine at the same dosage as adults. However, because elderly patients may have reduced renal function, they should be monitored for any signs of systemic toxicity. Dose adjustments are not typically required for topical ophthalmic use. |
| Renal Impairment | No dose adjustment is required for topical ophthalmic use in patients with renal impairment, as systemic absorption is minimal. However, if used in high doses or if the patient has severe renal impairment, monitoring may be advised. |
| Hepatic Impairment | No dose adjustment is required for topical ophthalmic use in patients with hepatic impairment, as systemic absorption is minimal. |
| Maximum Daily Dose | The maximum daily dose for topical ophthalmic use is not established from available information. Follow your doctor's prescription. |
