Dorzolamide drug data and news

Dorzolamide drug data, resources, and news articles (when available). Onconews.org provides news on cancer research. This section, which includes profiles on medicines that may or not be cancer-related is in beta form. If things run smoothly we will be releasing a new format late in the summer of 2006.

Description Not Available
Pharmacology Dorzolamide is topical carbonic anhydrase inhibitor. Dorzolamide is indicated for the reduction of elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension who are insufficiently responsive to beta-blockers.
Mechanism Of Action Dorzolamide is a sulfonamide and a human carbonic anhydrase II inhibitor. Inhibition of carbonic anhydrase II 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.

Interactions Interactions for Dorzolamide:

Although acid-base and electrolyte disturbances were not reported in the clinical trials with TRUSOPT, these disturbances have been reported with oral carbonic anhydrase inhibitors and have, in some instances, resulted in drug interactions (e.g., toxicity associated with high-dose salicylate therapy). Therefore, the potential for such drug interactions should be considered in patients receiving TRUSOPT.

Toxicity Dizziness, headache, shortness of breath, slow heartbeat, severe asthma, cardiac arrest
