Abstract

The invention discloses a haemocoagulase sublingual membrane and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. The haemocoagulase sublingual film of Agkistrodon lanceolata is prepared from the following raw materials: haemagglutinase from Agkistrodon lanceolata, PVA05-88, PEG-400, hydroxypropyl-β-cyclodextrin borneol inclusion compound and purified water. The preparation method includes: adding PVA05‑88 to purified water, stirring it with magnetic force to disperse evenly and fully swell it, wait for it to cool to room temperature, and set aside; add the remaining raw materials to the above solution in turn, stir well, and let stand to remove air bubbles , apply a film with a thickness of 40 to 60 μm on a film coating machine, and dry it at room temperature at 25°C in a ventilated and cool place to obtain the sublingual film of Agkistrodon haemocoagulase. The invention has the following advantages: it can be quickly absorbed by the oral mucosa to achieve the purpose of rapid onset of effect; oral administration does not require water, and is especially suitable as a first-aid hemostatic drug carried by individual soldiers.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a Agkistrodon haematocoagulase sublingual film and a preparation method thereof. Background technique [0002] Hemocoagulase BothropsAtrox is a hemostatic drug that can be widely used in various medical situations that require bleeding reduction or hemostasis, such as bleeding and bleeding disorders in various clinical departments; it can also be used to prevent bleeding, such as preoperative medication, Can avoid or reduce surgical site and postoperative bleeding. [0003] At present, the hemocoagulase of Agkistrodon haemorrhoids used clinically is freeze-dried powder injection. Based on the clinically good hemostatic effect of Haemocoagulase for Injection, it was selected as a medical emergency drug for rapid hemostasis in the battlefield. However, as an injection, under the special conditions of flight combat and airborne combat missions, comb...
