BRINZOLAMIDE

 BRINZOLAMIDE

BRAND NAME:- azopt, Brinzox , Brinolar 

BRINZOLAMIDE is a carbonic anhydrase inhibitor used to lower intraocular pressure in patients with open-angle glaucoma or ocular hypertension.

PHARMACODYNAMIC:-

Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion and thus lowers the intraocular pressure in the anterior chamber, presumably by reducing the rate of formation of bicarbonate ions with subsequent reduction in sodium and fluid transport; this may alleviate the effects of open-angle glaucoma.

  PHARMACOKINETICS:-

Brinzolamide is a topical carbonic anhydrase inhibitor which reduces the production of aqueous humor in the ciliary body, thereby reducing intra-ocular pressure. It is formulated as an ophthalmic suspension. The pharmacokinetics of ocular suspensions is not well understood. 

MECHANISM OF ACTION:-

Brinzolamide is a highly specific inhibitor of CA-II, which is the main CA isoenzyme involved in the secretion of aqueous humor. Inhibition of CA in the ciliary process of the eye slows the formation of bicarbonate, and reduces sodium and fluid transport. This results in a reduction in the rate of aqueous humor secretion and the intraocular pressure. Brinzolamide is absorbed systemically following topical ocular administration. Since it has a high affinity for CA-II, brinzolamide binds extensively to red blood cells, where CA-II is primarily found. As sufficient CA-II activity remains, adverse effects resulting from the systemic inhibition of CA by brinzolamide are not observed. The metabolite N-desethyl brinzolamide is also formed. This metabolite binds to CA and accumulates in red blood cells as well. In the presence of brinzolamide, the metabolite binds mainly to carbonic anhydrase I (CA-I). 

USES:-

used for the reduction of elevated intraocular pressure in patients with ocular hypertension or open-angle glaucoma.

SIDE EFFECTS:-

Temporary blurred vision, bitter/sour/unusual taste in your mouth, dry eyes, temporary discomfort/itching/redness of the eye, feeling as if something is in your eye, eye discharge, and headache may occur. 

DOSE:-  In topical used apply this medication in the affected areas. Consult your doctor or pharmacist .
