Indications
- Decrease of intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension for whom monotherapy provides insufficient IOP reduction.
Pharmacology
- Potent inhibitor of human carbonic anhydrase II (CA-II),
- Non-selective beta-adrenergic blocking agent
- Inhibition of CA-II in the ciliary processes of the eye decreases aqueous humour secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport.
- Tonography and fluorophotometry studies in man suggest that its predominant action is related to reducing aqueous humour formation and a slight increase in outflow facility.
Dosage & Administration
- The recommended dosage is one drop in the conjunctival sac of the affected eye(s) twice daily.
