Abstract

The invention belongs to the field of medicines and discloses a pharmaceutical composition of a triptolide-containing medicine and bracken and preparation and application thereof. The triptolide-containing medicine comprises triptolide, tripterygium glycosides, thunder god vine, tripterygium hypoglaucum hutch and tripterygium regelii. The pharmaceutical composition comprises the following raw materials in parts by weight: 1 part of triptolide and 100-107 parts of bracken or 1 part of tripterygium glycosides and 1-105 parts of bracken or 1 part of thunder god vine and 0.01-1000 parts of bracken or 1 part of tripterygium hypoglaucum hutch and 0.01-1000 parts of bracken or 1 part of tripterygium regelii and 0.01-1000 parts of bracken. Compared with the original medicine containing triptolide, the pharmaceutical composition has the advantages of immunological suppression, anti-inflammatory, treatment of rheumatoid arthritis, comparative antineoplastic activity and small toxicity, enhances the medication security and can be used as a medicine for immunological suppression, anti-inflammatory, rheumatoid arthritis and antitumor.

Description

technical field [0001] The invention belongs to the field of medicaments, and in particular relates to a pharmaceutical composition compatible with triptolide-containing medicaments and fern-tail grass, as well as its preparation and application. Background technique [0002] Triptolide is the most active epoxidized diterpene lactone compound isolated from the traditional Chinese medicine Tripterygium wilfordii Hook.f., and is one of the main active ingredients of Tripterygium wilfordii Hook.f. Triptolide is also present in two other plants of the genus Tripterygium, Kunming Mountain Begonia (Tripterygium Hypoglaucum Hutch) and Northeast Tripterygium (Tripterygium regalii Sprague et Take), and is also one of its main active ingredients. Due to the strong physiological activity of triptolide, it has significant immunosuppressive, anti-inflammatory, anti-tumor and anti-fertility effects, and is mainly used clinically to treat rheumatoid arthritis, lupus erythematosus, skin dis...
