Ethacrynic acid is classed in this group although it is not a sulfonamide. Thiazide diuretics (benzothiadiazines) include hydrochlorothiazide, benzthiazide, trichlormethiazide, and cyclothiazide. A long-acting analogue is chlorthalidone. These drugs affect the intermediate segment of the distal tubules, where they inhibit a Na+/Cl– cotransport.
Vit. D hormone promotes enteral absorption and renal reabsorption of Ca2+ and phosphate. As a result of the increased Ca2+ and phosphate concentration in blood, there is an increased tendency for these ions to be deposited in bone in the form of hydroxyapatite crystals. In vit. D deficiency, bone mineralization is inadequate (rickets, osteomalacia).

 

The speed of formation of hydrophilic metabolite determines the drug’s length of stay in the body. If hepatic conversion to a polar metabolite is rapid, only a portion of the absorbed drug enters the systemic circulation in unchanged form, the remainder having undergone presystemic (first-pass) elimination.
Low-molecular-weight heparin (average MW ~5000) has a longer duration of action and needs to be given only once daily (e. g. , certoparin, dalteparin, enoxaparin, reviparin, tinzaparin). Frequent control of coagulability is not necessary with low molecular weight heparin and incidence of side effects (bleeding, heparin-induced thrombocytopenia) is less frequent than with unfractionated heparin.
