Active Ingredient and Mechanism of Action:
Alphagan Eye Drops contain brimonidine tartrate (typically 0.15% or 0.2%), a sympathomimetic agent that acts as an alpha-2 adrenergic agonist. It reduces intraocular pressure (IOP) by decreasing the production of aqueous humour (fluid in the eye) and enhancing its drainage. This action helps protect the optic nerve from damage associated with high eye pressure, a key factor in conditions like open-angle glaucoma.
Indications:
- Alphagan Eye Drops are prescribed for: Open-angle glaucoma: The most common form of glaucoma where increased eye pressure can damage the optic nerve.
- Ocular hypertension: Elevated eye pressure without visual field loss, which may progress to glaucoma if untreated
Dosage and Administration:
- Use exactly as prescribed by a healthcare professional. Typically, one drop is instilled into the affected eye(s) at prescribed intervals.
- Remove contact lenses before administration and avoid touching the dropper tip to any surfaces to prevent contamination.
For best results, use daily at the same prescribed time, often in the evening or night 1 . 2 Sources Benefits Reduces intraocular pressure, lowering the risk of optic nerve damage.
