1,3-dmaa Overview
1,3-Dimethylamylamine (DMAA) is a synthetic compound that was once used in dietary supplements, primarily for its purported stimulant effects. It was marketed as a performance-enhancing and weight-loss aid due to its similarities to amphetamines. However, DMAA has been banned or restricted in several countries due to safety concerns, including reports of adverse effects such as increased blood pressure, heart rate, and potential links to serious health issues like strokes and heart attacks. As a result, DMAA is no longer commonly found in legal dietary supplements.
Dorzolamide, Timolol Overview
-
The combination of dorzolamide and timolol is used to treat eye conditions, including glaucoma and ocular hypertension, in which increased pressure can lead to a gradual loss of vision. Dorzolamide and timolol is used for patients whose eye condition has not responded to another medication. Dorzolamide is in a class of medications called topical carbonic anhydrase inhibitors. Timolol is in a class of medications called topical beta blockers. Dorzolamide and timolol lowers pressure in the eye by decreasing the production of natural fluids in the eye.
