MedKoo Cat#: 341515 | Name: Benzolamide

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Benzolamide is a carbonic anhydrase inhibitor. Benzolamide inhibits low-threshold calcium currents in hippocampal pyramidal neurons. Benzolamide improves oxygenation and reduces acute mountain sickness during a high-altitude trek and has fewer side effects than acetazolamide at sea level. Benzolamide perpetuates acidic conditions during reperfusion and reduces myocardial ischemia-reperfusion injury.
