What is Metahydrin?
Trichlormethiazide (INN, currently being sold under the brand names of Achletin, Diu-Hydrin and Triflumen) is a diuretic with properties similar to those of hydrochlorothiazide. In veterinary medicine, trichlormethiazide can be combined with dexamethasone to be used on horses with mild swelling of distal limbs and general bruising.
As a diuretic (in particular a thiazide), trichlormethiazide encourages water loss from the body. Trichlormethiazide works by inhibiting Na+/Cl− ion reabsorption from the distal tubules of the kidneys. In addition, trichlormethiazide increases the excretion of potassium.
