Description
Curator's Comment:: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/14534329

Cyclothiazide was presumably developed by Eli Lilly for the treatment of hypertension. It is believed that the drug, which belongs to the class of thiazide diuretics, exerts its action by inhibitin sodium reabsorption in the renal tubules. In 1993 it was discovered that cyclothiazide stimulates AMPA receptors thus inducing seizure behavior.
