TL;DR: In this article, an antitussive agent consisting of Cynanchi atratiradix extract (A) and carrier or excipient was used for preparation of (A).
Abstract: An antitussive agent comprises Cynanchi atratiradix extract (A) and carrier or excipient. An independent claim is included for preparation of (A). ACTIVITY : Antitussive. Pulverized dry material of Cynanchum atraturm (1 kg) was heated to boil and refluxed twice With 10 L of the following solvents: water (test-1), 50% ethanol (test-2), 95% ethanol (test-3), ethyl acetate (EA) (test-4) and hexane (test-5), respectively. The extracts were then filtered with 350 mesh sieve and the filtrates were collected, respectively. The filtrates were further centrifuged continuously at 1089xg ( Avanti J-251(RTM, High performance centrifuge)) for 3 hr to precipitate micropartic1es and impurities. The supernatants were further concentrated and freeze-dried. The inhibition activity of extracts (1 g/kg dosage) on citric acid induced cough was evaluated. The antitussive inhibition assessment showed at least 60% of citric acid-induced coughs. MECHANISM OF ACTION : None given.
