Tobramycin ophthalmic solution is an antibiotic eye drop used to treat bacterial infections of the eye. It belongs to the class of drugs known as aminoglycoside antibiotics and is effective against a variety of gram-negative and some gram-positive bacteria.
Key Features
- Active Ingredient: Each milliliter of Tobramycin ophthalmic solution typically contains 3 mg of tobramycin (0.3% concentration).

Indications
Tobramycin eye drops are indicated for:
- Bacterial Eye Infections: Effective in treating conditions such as conjunctivitis, keratitis, and other external infections caused by susceptible bacteria.
Mechanism of Action
Tobramycin works by inhibiting bacterial protein synthesis, which ultimately leads to bacterial cell death. This action helps eliminate the infection in the affected eye.
Dosage and Administration
- Typical Dosage:
- For mild to moderate infections: Instill 1-2 drops into the affected eye(s) every 4 hours.

1. Wash hands thoroughly before applying the drops.
2. Tilt your head back and pull down the lower eyelid to create a pouch.
3. Hold the dropper above the eye without touching it, and instill the prescribed number of drops.
