Overview

What is Azopt?

AZOPT (brinzolamide ophthalmic suspension) 1% contains a carbonic anhydrase inhibitor formulated for multidose topical ophthalmic use. Brinzolamide is described chemically as: (R)-(+)-4-Ethylamino-2-(3-methoxypropyl)-3,4-dihydro-2H-thieno [3,2-e]-1,2-thiazine-6-sulfonamide-1,1- dioxide. Its empirical formula is CHNOS, and its structural formula is:

Brinzolamide has a molecular weight of 383.5 and a melting point of about 131°C. It is a white powder, which is insoluble in water, very soluble in methanol and soluble in ethanol. AZOPT (brinzolamide ophthalmic suspension) 1% is supplied as a sterile, aqueous suspension of brinzolamide which has been formulated to be readily suspended and slow settling, following shaking. It has a pH of approximately 7.5 and an osmolality of 300 mOsm/kg. Each mL of AZOPT (brinzolamide ophthalmic suspension) 1% contains: brinzolamide 10 mg. Benzalkonium chloride 0.1 mg. mannitol, carbomer 974P, tyloxapol, edetate disodium, sodium chloride, purified water, with hydrochloric acid and/or sodium hydroxide to adjust pH.



What does Azopt look like?



What are the available doses of Azopt?

Solution containing 10 mg/mL brinzolamide.

What should I talk to my health care provider before I take Azopt?

How should I use Azopt?

AZOPT (brinzolamide ophthalmic suspension) 1% is a carbonic anhydrase inhibitor indicated in the treatment of elevated intraocular pressure in patients with ocular hypertension or open-angle glaucoma.

The recommended dose is one drop of AZOPT (brinzolamide ophthalmic suspension) 1% in the affected eye(s) three times daily. AZOPT (brinzolamide ophthalmic suspension) 1% may be used concomitantly with other topical ophthalmic drug products to lower intraocular pressure. If more than one topical ophthalmic drug is being used, the drugs should be administered at least ten (10) minutes apart.

What should I look out for while using Azopt?

AZOPT (brinzolamide ophthalmic suspension) 1% is contraindicated in patients who are hypersensitive to any component of this product.


What might happen if I take too much Azopt?

Although no human data are available, electrolyte imbalance, development of an acidotic state, and possible nervous system effects may occur following oral administration of an overdose. Serum electrolyte levels (particularly potassium) and blood pH levels should be monitored.


How should I store and handle Azopt?

Store at room temperature 20° to 25°C (68°to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) [See USP Controlled Room Temperature].AZOPT (brinzolamide ophthalmic suspension) 1% is supplied in plastic DROP-TAINER dispensers with a controlled dispensing-tip as follows: 10 mL NDC 0065-0275-1015 mL NDC 0065-0275-15 Store AZOPT (brinzolamide ophthalmic suspension) 1% at 4 to 30°C (39 to 86°F). Shake well before use.

Clinical Pharmacology

Carbonic anhydrase (CA) is an enzyme found in many tissues of the body including the eye. It catalyzes the reversible reaction involving the hydration of carbon dioxide and the dehydration of carbonic acid. In humans, carbonic anhydrase exists as a number of isoenzymes, the most active being carbonic anhydrase II (CA-II), found primarily in red blood cells (RBCs), but also in other tissues. Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport. The result is a reduction in intraocular pressure (IOP). AZOPT (brinzolamide ophthalmic suspension) 1% contains brinzolamide, an inhibitor of carbonic anhydrase II (CA-II). Following topical ocular administration, brinzolamide inhibits aqueous humor formation and reduces elevated intraocular pressure. Elevated intraocular pressure is a major risk factor in the pathogenesis of optic nerve damage and glaucomatous visual field loss.

Non-Clinical Toxicology
AZOPT (brinzolamide ophthalmic suspension) 1% is contraindicated in patients who are hypersensitive to any component of this product.







As with all drugs, care should be exercised when treating patients with multiple medications. Diltiazem is both a substrate and an inhibitor of the cytochrome P-450 3A4 enzyme system. Other drugs that are specific substrates, inhibitors, or inducers of this enzyme system may have a significant impact on the efficacy and side effect profile of diltiazem. Patients taking other drugs that are substrates of CYP450 3A4, especially patients with renal and/or hepatic impairment, may require dosage adjustment when starting or stopping concomitantly administered diltiazem in order to maintain optimum therapeutic blood levels.

AZOPT (brinzolamide ophthalmic suspension) 1% is a sulfonamide and although administered topically it is absorbed systemically. Therefore, the same types of adverse reactions that are attributable to sulfonamides may occur with topical administration of AZOPT (brinzolamide ophthalmic suspension) 1%. Fatalities have occurred, although rarely, due to severe reactions to sulfonamides including Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, aplastic anemia, and other blood dyscrasias. Sensitization may recur when a sulfonamide is re-administered irrespective of the route of administration. If signs of serious reactions or hypersensitivity occur, discontinue the use of this preparation.
