Abstract

The invention provides an intragastric floating tablet for periplaneta americana. The intragastric floating tablet is a tablet prepared from periplaneta americana powder or periplaneta americana extracting solution as an active ingredient and an auxiliary material, wherein the weight ratio of the active ingredient to the auxiliary material is 1:(1-30), preferably 1:(2-20), and more preferably 1:19. The intragastric tablet can stay longer in stomach, can well treat helicobacter pylori infection gastritis, peptic ulcer and gastric cancer, and has a wide market prospect.

Description

technical field [0001] The invention belongs to the field of new pharmaceutical technology, and relates to a new dosage form, in particular to a preparation method and application of a gastric floating tablet. Background technique [0002] The American cockroach is native to South America and is the largest insect in the cockroach family. Adults are 29-35 mm long, reddish-brown, with wings longer than the end of the abdomen. The antennae are very long, there are large butterfly-shaped brown stripes in the middle of the pronotum, and the trailing edge of the stripes has a complete yellow stripe. The components of Periplaneta americana can activate blood and dissipate blood stasis, detoxify and eliminate chancre, diuresis and reduce swelling. Under normal circumstances, the stomach wall has a series of perfect self-protection mechanisms, which can resist the invasion of thousands of microorganisms that enter by mouth. Studies have shown that Helicobacter pylori has a strong...
