The Uses of Trichlormethiazide
Trichlormethiazide is a diuretic and anti-hypertensive agent from the benzothiadiazide class which is used in veterinary medicine in cattle, sheep, goats, pigs and horses, at the following therapeutic regimen: a single intramuscular dose of 0.4 mg/kg bw followed by two oral doses of 0.8 mg/kg bw given 12 and 36 hours after the first administration.
Trichlormethiazide is also used in humans in the United States as a diuretic and anti-hypertensive substance but not in the European Union. The usual dose is 2 to 4 mg twice a day (i.e. approximately 0.033 to 0.066 mg/kg bw/day).
The Uses of Trichlormethiazide
diuretic, antihypertensive
The Uses of Trichlormethiazide
Trichlormethiazide, is a diuretic, having similar properties as Hydrochlorothiazide (H714560). It is used for the treatment of oedema (including that which is associated with heart failure, hepatic cirrhosis and corticosteroid therapy) and hypertension.
Indications
Used in the treatment of oedema (including that associated with heart failure) and hypertension.
Background
A thiazide diuretic with properties similar to those of hydrochlorothiazide. (From Martindale, The Extra Pharmacopoeia, 30th ed, p830)
Definition
ChEBI: Trichlormethiazide is a benzothiadiazine, hydrogenated at positions 2, 3 and 4 and substituted with an aminosulfonyl group at C-7, a chloro substituent at C-6 and a dichloromethyl group at C-3 and with S-1 as an S,S-dioxide. A sulfonamide antibiotic, it is used as a diuretic to treat oedema (including that associated with heart failure) and hypertension. It has a role as a diuretic and an antihypertensive agent. It is a benzothiadiazine and a sulfonamide antibiotic.
Manufacturing Process
A mixture of 5.7 grams (0.02 mol) of 5-chloro-2,4-disulfamylaniline and 4.9 grams (0.04 mol) of dichloroacetaldehyde in 25 ml of dimethyl formamide was heated at the boiling temperature and under reflux for 30 minutes. The reaction mixture was thereafter poured into a mixture of ice and water to precipitate the desired 6-chloro-7-sulfamyl-3-dichloromethyl-3,4-dihydro- 1,2,4-benzothiadiazine-1,1-dioxide as a crystalline solid melting at 250° to 270°C with decomposition.
Therapeutic Function
Diuretic
Pharmacokinetics
Trichloromethiazide is indicated as adjunctive therapy in edema associated with congestive heart failure, hepatic cirrhosis, and corticosteroid and estrogen therapy. Trichloromethiazide has also been found useful in edema due to various forms of renal dysfunction such as nephrotic syndrome, acute glomer-ulonephritis, and chronic renal failure. Trichloromethiazide is also indicated in the management of hypertension either as the sole therapeutic agent or to enhance the effectiveness of other antihypertensive drugs in the more severe forms of hypertension. Like other thiazides, Trichloromethiazide promotes water loss from the body (diuretics). They inhibit Na+/Cl- reabsorption from the distal convoluted tubules in the kidneys. Thiazides also cause loss of potassium and an increase in serum uric acid. Thiazides are often used to treat hypertension, but their hypotensive effects are not necessarily due to their diuretic activity. Thiazides have been shown to prevent hypertension-related morbidity and mortality although the mechanism is not fully understood. Thiazides cause vasodilation by activating calcium-activated potassium channels (large conductance) in vascular smooth muscles and inhibiting various carbonic anhydrases in vascular tissue.
