Mechanism & Pharmacology
Both Tobramycin and Dexamethasone work synergistically to address bacterial infections and inflammation in the eye.
Tobramycin, an aminoglycoside antibiotic, disrupts bacterial protein synthesis, effectively helping to eliminate infection. Dexamethasone, a corticosteroid, reduces inflammation by inhibiting multiple inflammatory pathways and suppressing the immune response in ocular tissues.
Clinical terms
Understanding some of the clinical jargon associated with Tobramycin and Dexamethasone can be beneficial:
- Aminoglycoside: This class of antibiotics is used primarily to treat infections caused by gram-negative bacteria.
- Corticosteroid: A steroid hormone used in treatment to reduce inflammation.
- Ophthalmic: Pertaining to the eye, specifically medications applied directly to ocular tissues.
Grasping these terms can empower patients to engage more effectively in discussions about their treatment options and outcomes.
Indications & Off-Label Uses
Tobramycin and Dexamethasone is a fixed-dose combination ophthalmic medication primarily indicated for the treatment of bacterial eye infections and inflammation. This dual-action medication combines an aminoglycoside antibiotic with a corticosteroid to address both infection and associated inflammatory responses.
