Abstract
The invention discloses a compound telmisartan hydrochlorothiazide pharmaceutical composition, which is a tablet. For the tablet, hydrochlorothiazide and telmisartan are prepared into a coated tablet so as to make the telmisartan and the hydrochlorothiazide in the telmisartan hydrochlorothiazide pharmaceutical composition respectively released. The composition has a controlled release effect and improves the bioavailability. The employment of a coated tablet preparation process can make the two medicines effectively released successively. The pharmaceutical composition has a controlled release effect, maintains a long-term blood concentration, has a more stable blood pressure reduction effect, and reduces adverse reactions.
Description
technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a telmisartan hydrochlorothiazide pharmaceutical composition and a new preparation method thereof. Background technique [0002] Telmisartan is a new antihypertensive drug and a specific angiotensin II receptor (AT I type) antagonist. Compared with other antihypertensive drugs, telmisartan has the following characteristics: specificity of receptor action, significant antihypertensive effect, good diuretic effect, can improve myocardial stenosis, drug safety, and tolerance Good 1 time a day, easy to take. [0003] The chemical name is: 4-{[2-n-propyl-4-methyl-6-(1-methylbenzimidazol-2-yl)benzimidazol-1-yl]methyl}biphenyl-2 -Carboxylic acid [0004] Molecular formula: C 33 h 30 N 4 o 2 ; [0005] Molecular weight: 514.62; [0006] Hydrochlorothiazide [0007] The chemical name is: 3-ethyl-5-methyl-2-(2-aminoethoxymethyl)-4-(2-chlorophenyl)-1,4-dihydro...
