Alphagan P (brimonidine tartrate and timolol maleate ophthalmic solution) lowers eye pressure by increasing outflow of aqueous humor and decreasing its production. It’s a combination medication, meaning it contains two active ingredients working together for enhanced efficacy.
Understanding the Ingredients
Brimonidine, an alpha2-adrenergic agonist, reduces the production of aqueous humor. Timolol, a beta-blocker, further lowers pressure by increasing the outflow of aqueous humor. This dual mechanism makes Alphagan P particularly effective in managing intraocular pressure (IOP) in patients with glaucoma or ocular hypertension.
Dosage and Administration
Typically, one drop is instilled into the affected eye(s) twice daily. Always follow your ophthalmologist’s instructions precisely. Avoid touching the dropper tip to any surface, including the eye, to prevent contamination. If using multiple eye drops, allow at least 5-10 minutes between applications.
Potential Side Effects
Common side effects include burning or stinging upon application, blurred vision, and dry eyes. Less common but more serious side effects require immediate medical attention. These can include changes in heart rate, breathing problems, or allergic reactions. Consult your doctor if you experience any concerning symptoms.
Precautions and Interactions
Alphagan P may interact with other medications, particularly those affecting heart rate or blood pressure. Inform your doctor of all medications you are taking, including over-the-counter drugs and supplements. Patients with certain heart conditions, respiratory problems, or allergies should exercise caution. Pregnancy and breastfeeding should also be discussed with your physician before commencing treatment.
Storage and Disposal
Store Alphagan P at room temperature, away from direct sunlight and heat. Discard any unused medication after the expiration date printed on the bottle. Never reuse an opened bottle of Alphagan P.
