It is freely soluble in formic acid, sparingly soluble in water, slightly soluble in acetic acid (100), and very slightly soluble in ethanol (99.5). PHARMACEUTICAL FORM Brand name Harnal D 0.2 mg Tablet Active ingredient (Content per tablet) Tamsulosin hydrochloride 0.2 mg Appearance (mm) Orally dispersible tablet Diameter: 8.5 Thickness: 4.2 Weight (g) 0.20 Color White Identification code PHARMACOLOGY 1. PHARMACOLOGICAL EFFECTS (1) EFFECTS IN HUMANS In a receptor binding assay using human prostate preparations, tamsulosin hydrochloride was 2.2 times more potent than prazosin hydrochloride and 40 times more so than phentolamine mesylate in 1 -receptor blocking activity. (2) EFFECTS IN ANIMALS 1) Blockade of -adrenergic receptors In a receptor binding assay using isolated rat cerebral membrane and an _ in vitro _ experiment using isolated rabbit aorta, tamsulosin hydrochloride inhibited 1 -receptors selectively and competitively. Its action was 1/2.2 to 22 times more potent than prazosin hydrochloride and 45 to 140 times more potent than phentolamine mesylate. _In vitro _ experiments using isolated rabbit aorta, isolated rat vas deferens and isolated guinea pig intestine, tamsulosin hydrochloride proved to be 5,400 to 24,000 times more selective for 1 - receptors than for 2 -receptors. 2) Effect on the lower urinary tract (urethra and urinary bladder) and prostate In a receptor binding assay using isolated smooth muscle from rabbit urethra, prostate and urinary bladder base, tamsulosin hydrochloride was 23 to 98 times more potent than prazosin hydrochloride in 1 -receptor blocking activity, and 87 to 320 times more potent than phentolamine mesylate. In anesthetized dogs, the drug inhibited the 1 -agonist (phenylephrine)-induced increase in intrauretheral pressure with 13 times greater potency than the increase in diastolic blood pressure. 3) Improv Baca dokumen lengkapnya
