Cyclothiazide (Anhydron, Aquirel, Doburil, Fluidil, Renazide, Tensodiural, Valmiran) is a benzothiadiazide (thiazide) diuretic and antihypertensive that was originally introduced in the United States in 1963 by Eli Lilly and was subsequently also marketed in Europe and Japan.[1][2] Related drugs include diazoxide, hydrochlorothiazide, and chlorothiazide.[3]

In 1993, it was discovered that cyclothiazide is a positive allosteric modulator of the AMPA receptor, capable of reducing or essentially eliminating rapid desensitization of the receptor, and potentiating glutamate currents by as much as 18-fold at the highest concentration tested (100 μM).[4][5][6][3] Additionally, in 2003, cyclothiazide was also found to act as a GABAA receptor negative allosteric modulator, potently inhibiting GABAA-mediated currents.[7] In animals it is a powerful convulsant, robustly enhancing epileptiform activity and inducing seizures, but interestingly without producing any apparent neuronal death.[8][9]
