Bajaten - General Information
A benzamide-sulfonamide-indole. It is called a thiazide-like diuretic but structure is different enough (lacking the thiazo-ring) so it is not clear that the mechanism is comparable.
Pharmacology of Bajaten
Bajaten is an antihypertensive and a diuretic. It contains both a polar sulfamoyl chlorobenzamide moiety and a lipid- soluble methylindoline moiety. Bajaten bears a structural similarity to the triazide diuretics which are known to decrease vascular smooth muscle reactivity. However, it differs chemically from the thiazides in that it does not possess the thiazide ring system and contains only one sulfonamide group. Bajaten appears to cause vasodilation, probably by inhibiting the passage of calcium and other ions (sodium, potassium) across membranes. This same effect may cause hypokalcemia in susceptible individuals. Bajaten has also been shown to cause uterine myometrial relaxation in experimental animals. Overall, indapamide has an extra-renal antihypertensive action resulting in a decrease in vascular hyperreactivity and a reduction in total peripheral and arteriolar resistance.
Bajaten for patients
Anuria. Known hypersensitivity to indapamide or to other sulfonamide-derived drugs.
Additional information about Bajaten
Bajaten Indication: For the treatment of hypertension, alone or in combination with other antihypertensive drugs as well as for the treatment of salt and fluid retention associated with congestive heart failure or edema from pregnancy.
Mechanism Of Action: Bajaten blocks the slow component of delayed rectifier potassium current (IKs) without altering the rapid component (IKr) or the inward rectifier current. Specifically it blocks or antagonizes the action the proteins KCNQ1 and KCNE1. Bajaten is also thought to stimulate the synthesis of the vasodilatory hypotensive prostaglandin PGE2.
Drug Interactions: Amantadine The diuretic increases the adverse effect of amantadine
Deslanoside Possible electrolyte variations and arrhythmias
Diazoxide Significant hyperglycemic effect
Digitoxin Possible electrolyte variations and arrhythmias
Digoxin Possible electrolyte variations and arrhythmias
Dofetilide Increased risk of cardiotoxicity and arrhythmias
Lithium The thiazide diuretic increases serum levels of lithium
Food Interactions: Take without regard to meals. Magnesium, potassium and zinc needs increased.
