Theophylline monohydrate 似乎抑制磷酸二酯酶和前列腺素的产生,调节钙通量和细胞内钙分布,并拮抗腺苷。茶碱是黄嘌呤的天然生物碱衍生物,从植物山茶花和小粒咖啡中分离出来。在生理上,该药剂可放松支气管平滑肌,产生血管舒张(脑血管除外),刺激中枢神经系统,刺激心肌,利尿,增加胃酸分泌;它还可以抑制炎症并改善横膈膜的收缩性。
产品描述
Theophylline appears to inhibit phosphodiesterase and prostaglandin production, regulate calcium flux and intracellular calcium distribution, and antagonize adenosine. Theophylline is a natural alkaloid derivative of xanthine isolated from the plants Camellia sinensis and Coffea arabica. Physiologically, this agent relaxes the bronchial smooth muscle, produces vasodilation (except in cerebral vessels), stimulates the CNS, stimulates the cardiac muscle, induces diuresis, and increases gastric acid secretion; it may also suppress inflammation and improve contractility of the diaphragm.
