Abstract

The invention discloses a sildenafil citrate sublingual tablet and a preparation method thereof. The sildenafil citrate sublingual tablet is prepared from 1 part by weight of sildenafil citrate and 4 to 8 parts by weight of pharmaceutical adjuvant , wherein the pharmaceutical adjuvant comprises 2 to 4 percent of disintegrant, 94 to 96 percent of diluter, 0.5 to 1.2 percent of lubricator, 0.3 to 1 percent of corrective and 0.1 to 0.2 percent of binder, which are based on the total weight of the pharmaceutical adjuvant. Test results show that the prepared sublingual tablet has shorter disintegration time, higher dissolving speed in vitro and higher body bioavailability than the conventional tablets.
