The thiazide receptor is a sodium-chloride transporter that pulls NaCl from the lumen in the distal convoluted tubule. Thiazide diuretics inhibit this receptor, causing the body to release NaCl and water into the lumen, thereby increasing the amount of urine produced each day. [6] An example of a molecule that is chemically a thiazide but not ...
The sodium-chloride symporter (also known as Na +-Cl − cotransporter, NCC or NCCT, or as the thiazide-sensitive Na +-Cl − cotransporter or TSC) is a cotransporter in the kidney which has the function of reabsorbing sodium and chloride ions from the tubular fluid into the cells of the distal convoluted tubule of the nephron.
It contains olmesartan medoxomil, an angiotensin II receptor blocker, amlodipine, as the besilate, a calcium channel blocker, and hydrochlorothiazide, a thiazide diuretic. [3] It is taken by mouth. [3]
Hydrochlorothiazide, sold under the brand name Hydrodiuril among others, is a diuretic medication used to treat hypertension and swelling due to fluid build-up. [4] Other uses include treating diabetes insipidus and renal tubular acidosis and to decrease the risk of kidney stones in those with a high calcium level in the urine. [4]
On its apical surface (lumen side), cells of the DCT have a thiazide-sensitive Na-Cl cotransporter and are permeable to Ca, via the TRPV5 channel. On the basolateral surface (peritubular capillary side) there is an ATP-dependent Na/K antiporter pump, a secondary active Na/Ca transporter, and an ATP dependent Ca transporter.
Serious side effects may include low blood pressure, kidney problems, allergic reactions, and electrolyte problems. [1] Use in pregnancy and breastfeeding is not recommended. [ 3 ] Losartan works by blocking the effects of angiotensin II while hydrochlorothiazide works by decreasing the ability of the kidneys to absorb electrolytes.
[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 and kainate receptors , capable of reducing or essentially eliminating rapid desensitization of the former receptor, and potentiating AMPA-mediated glutamate ...
Thiazide diuretics increase the excretion of sodium and potassium ions and decrease the excretion of calcium ions and uric acid so they are contraindicated in patients with hyponatraemia, hypokalaemia, hypercalcaemia and hyperuricaemia.
