Mechanism of Action
- Lowers IOP by reducing the formation of aqueous humor via beta 1 and beta 2 receptors.
- Increases aqueous humor outflow, contributing to the reduction of IOP.
Dosage and Administration
- Administered as 1-2 drops of a 0.25-0.5% solution.
- Typical dosage frequency is 1-2 times per day.
Laboratory Considerations
- Monitor levels of uric acid, glucose, and potassium (K+) during treatment.
Contraindications
- Not recommended for patients with asthma, COPD, bradycardia, second or third degree AV block, heart failure, cardiogenic shock, or hypersensitivity to the drug.
Drug Interactions
- Caution advised with other beta blockers, nitrates, and epinephrine due to potential interactions.
Side Effects

Adverse Effects
- Systemic absorption may lead to serious conditions such as angina, anxiety, bronchoconstriction, hypertension, and dysrhythmias.
Desired Outcomes
- Effective treatment results in reduced intraocular pressure, serving its purpose as an anti-glaucoma medication.
Patient Education
- Instruct patients not to touch the dropper to their eye to avoid contamination.
Metabolism
- Metabolized in the cornea and liver, influencing its pharmacokinetics and overall effectiveness.
