Abstract

The invention discloses a dapoxetine hydrochloride orally disintegrating tablet and a preparation method thereof. The orally disintegrating tablet comprises dapoxetine hydrochloride, fillers, disintegrating agents, dried binding agents, penetration promoting flavoring agents and lubricating agents. The orally disintegrating tablet is prepared by a direct tablet pressing method. The orally disintegrating tablet has the advantages that the orally disintegrating tablet is simple in preparation process, low in cost and convenient to take and has high effect on male premature ejaculation. The orally disintegrating tablet contains 0.1%-2% of penetration promoting flavoring agents, the taste of the orally disintegrating tablet is improved, stability of the orally disintegrating tablet is improved, absorption of the orally disintegrating tablet is further improved, the maximum plasma concentration (Cmax) is achieved within 0.5-1 hour after the orally disintegrating tablet is taken, effect taking time becomes earlier, and bioavailability is remarkably improved.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a dapoxetine hydrochloride orally disintegrating tablet and a preparation method and application thereof. Background technique [0002] Dapoxetine hydrochloride is a white to off-white crystalline powder that is easily oxidized. The chemical name is (S)-(+)-N,N-dimethyl-3-(1-naphthyloxy)amphetamine hydrochloride, and its structural formula is as follows: [0003] [0004] Dapoxetine, which was first researched and developed by Eli Lilly in the United States, was used for the treatment of antidepressant and underwent phase I clinical trials. The antidepressant effect was not satisfactory, and then this product was transferred to PP Tian Pharmaceutical Group, After the discovery of its subsidiary PP Tian Genu Pro, it was used to treat premature ejaculation patients, and a phase II clinical trial was carried out; finally, all this product was transferred to Alza, a div...
