2. What is Tobramycin Eye Drops? (Tobramycin Eye Drops kya hai)

Tobramycin Eye Drops (Tobrex) are commonly prescribed antibiotic eye drops for bacterial eye infections in Pakistan. The Alcon brand is marketed as Tobrex; local generic brands are also available.

Tobramycin is an aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit and inhibits bacterial protein synthesis — bactericidal action. It is effective against a wide range of Gram-positive and Gram-negative bacteria, including Pseudomonas aeruginosa.
