Abstract
An anti-fatigue pharmaceutical composition and a preparation method thereof. The pharmaceutical composition includes active ingredients and medically acceptable excipients. The active ingredients are the following raw materials in weight percentages: Astragalus 3-9 weight parts, Nansha ginseng 3-9 parts by weight, 3-9 parts by weight of Rehmannia glutinosa. The pharmaceutical composition has anti-fatigue effect. In vivo pharmacological experiment results prove that the medicine of the present invention can significantly prolong the time of mice swimming under load, reduce the content of MDA in gastrocnemius muscle and liver tissue, increase the activity of SOD, CAT and GSH-Px and the content of glycogen in gastrocnemius muscle and liver tissue; In addition, it can also regulate the expression of Nrf2 and HO‑1 related proteins in mouse gastrocnemius muscle and liver tissues. The invention can be used to prepare the medicine for treating fatigue, and has the advantages of quick improvement of symptoms and short course of treatment as proved by experiments.
Description
technical field [0001] The invention relates to the technical field of biomedicine, in particular to an anti-fatigue pharmaceutical composition and a preparation method thereof. Background technique [0002] Fatigue is the inability of the body's physiological process to maintain its function at a specific level or the inability of an organ to maintain its predetermined exercise intensity. With the rapid development of society and the accelerated pace of life, long-term intense work, competitive pressure and emotional instability can easily lead to fatigue. Today, fatigue has become one of the main factors that endanger human health. If body fatigue is not eliminated in time, it will gradually accumulate and lead to emotional abnormalities. Over time, it will form chronic fatigue syndrome and even lead to death from overwork. Therefore, it is of great practical significance to study safe, effective and popular functional active products. [0003] Fatigue is the inability ...
