The kinetics of interferon production in warm blooded animals (humans and mice) with intraperitoneal and oral administration of dipyridamole have shown this substance to possess a high interferon-inducing activity when administered orally at single doses ranging from 12.5 to 100 mg/kg (1/21.5 - 1/172 of the single LD50 value). Peak titres of 2048 - 4096 IU/ml in the blood serum were reached at the 48th hour and elevated interferon levels persisted until the 5th day post inducer administration. Significantly lower interferon titres were found after intraperitoneal injection. Dipyridamole is also effective in in vitro induction of interferon.
对温血动物(人和小鼠)腹腔和口服
双嘧达莫产生干扰素的动力学研究表明,当口服单次剂量为 12.5 至 100 毫克/千克(单次半数致死剂量的 1/21.5 - 1/172)时,这种物质具有很高的干扰素诱导活性。血清中的峰值滴度在第 48 小时达到 2048 - 4096 IU/ml,干扰素
水平的升高一直持续到服用诱导剂后的第 5 天。腹腔注射后,干扰素滴度明显降低。
双嘧达莫在体外诱导干扰素方面也很有效。
