How Conjunctivitis Medications Work

Conjunctivitis, an inflammation of the conjunctiva, can be caused by bacterial or viral infections. The primary goal of medication is to eliminate the underlying pathogen and reduce symptoms.

Gold Standard: Antibiotic Eye Drops

• Topical Antibiotics: Effective against bacterial conjunctivitis, particularly Staphylococcus aureus.

• Examples include gentamicin, tobramycin, and ciprofloxacin eye drops.

• These medications work by inhibiting protein synthesis in bacteria, ultimately killing the pathogen.

Alternatives: Antiviral Eye Drops, Mast Cell Stabilizers, and Corticosteroid Eye Drops

• Antiviral Eye Drops: Effective against viral conjunctivitis, particularly Adenovirus.

• Examples include trifluridine and idoxuridine eye drops.

• Mast Cell Stabilizers (e.g., cromolyn sodium) can reduce inflammation and itching.

• Corticosteroid Eye Drops (e.g., prednisolone) can reduce inflammation, but should be used with caution due to potential side effects.
