Biochemical and Physiological Mechanisms

Methazolamide has a plasma half-life of 14 hours in humans. Methazolamide has relatively good lipid solubility and low plasma protein binding ability. Thus, it diffuses into tissues and fluids much more readily than acetazolamide, another carbonic anhydra

Note

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
