Generic Brinzolamide timolol
Company Osl pharma limited

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.
