Application

Acetazolamide has been used:
  • to study its protective effect on steatotic liver grafts against cold ischemia reperfusion injury{49)
  • to determine its ability to bind isolated porcine retinal pigment epithelium (RPE) melanin by cassette dosing and rapid equilibrium dialysis inserts
  • to validate the in vitro gastrulation model of P19C5 stem cells for developmental toxicity screening assays
  • to study its inhibitory effect on melanogenesis through enzyme kinetic, in vitro, in vivo and in silico analyses in zebrafish and in A375 human melanoma cells

Carbonic anhydrase inhibitor; increases cerebral blood flow.

Biochem/physiol Actions

Acetazolamide is a member of sulfonamide drug family. It as an ability to inhibit the activity of carbonic anhydrase. It rapidly increases cerebral blood flow (CBF) and is used as an investigative tool in CBF studies. Acetazolamide acts as a therapeutic agent for epilepsy, glaucoma and pseudotumor cerebri.
Inhibits water permeability of membranes by interacting with aquaporins
