Embodiment 1

[0022]

[0023] The preparation method is as follows: Take the prescribed amount of irbesartan, hydrochlorothiazide, carrageenan, and mannitol, mix evenly, use water as the binder, granulate with 24 mesh, dry under reduced pressure at 45°C for 2 hours, granulate with 18 mesh, add the prescribed amount The cross-linked polyvinylpyrrolidone and talcum powder are mixed uniformly and filled into No. 0 capsules.

[0024] Cumulative release test results: the release of irbesartan-hydrochlorothiazide capsules prepared by the present invention is close to 0-order release, while the commercially available irbesartan-hydrochlorothiazide capsules have obvious burst release in vivo due to the presence of secondary administration.

Abstract

The invention discloses an irbesartan hydrochlorothiazide capsule. The capsule includes the components of irbesartan, hydrochlorothiazide, carrageenan, mannitol, crosslinked polyvinylpyrrolidone and talcum powder. The irbesartan hydrochlorothiazide capsule enables medicines to slowly release step by step, the phenomenon of sudden releasing cannot occur, blood concentration is stable, medicine effect can maintain more than 8 hours, adverse reaction caused by medicine sudden releasing is avoided, and pharmacy safety is added. The irbesartan hydrochlorothiazide capsule can be used for treating primary hypertension.
