Patients were divided into three groups randomly. Group A: 25 patients received a single dose of 1.88 mg Decapeptyl; Group B: 20 patients had a single dose of 2.50 mg Decapeptyl; Group C: 15 patients had a single dose of 3.75 mg Decapeptyl. Results The LH levels were 2.00±0.77 IU/L in Group A, 1.05±0.44 IU/L and 0.95 ±0.48 IU/L in Group B and C respectively on the day of starting gonadotropin injection; 1.97±0.76 IU/L in Group A, 0.96±0.42 IU/L and 0.77±0.49 IU/L in Group B and C respectively on the day of hCG administration. The LH levels in Group B and Group C were significantly lower than those in Group A (P<0.01). The mean number of gonadotropin ampoules was higher in Group B (38.05±6.08 ampoules) and Group C (40.0±10.62 ampoules) than in Group A (29.96±4.98 ampoules) (P< 0.01). The duration of stimulation significantly increased in Group B (12.9±1.81 d) and Group C (13.6±2.63 d) as compared with that in Group A (11.24±1.36 d) (P<0.01). There were no differences among three groups in E_2 levels on the day of hCG administration, the number of retrieved oocytes, fertilization rate, cleavage rate or pregnancy rate. There was no presence of LH peak in all groups. Conclusion The use of 1.88 mg Decapeptyl provides successful rate similar to 2.50 mg and 3.75 mg Decapeptyl, resulting in the reduced amount of gonadotropin, the duration of stimulation and the cost of treatment. The dose of 1.88 mg Decapeptyl is sufficient for pituitary down-regulation of IVF program for Chinese women.展开更多

文摘目的研究两种长效曲普瑞林注射剂(达必佳3.75 mg及达菲林3.75 mg)在Beagle犬体内的药动学参数。方法 10条健康雄性Beagle犬随机分成2组,肌注达必佳或达菲林,采用经验证的LC-MS/MS法测定Beagle犬血浆中曲普瑞林浓度。使用DAS 3.2.2软件计算药动学参数。结果达必佳和达菲林主要药动学参数Cmax为(11.95±2.127)与(27.93±8.752)ng/mL、Tmax为(1.2±0.4)与(0.7±0.3)h、T1/2为(244.7±99.25)与(239.6±87.50)h、AUC(0-t)为(758.8±111.9)与(492.3±125.9)ng h mL-1、AUC(0-)为(778.9±101.3)与(515.6±125.3)ng h mL-1。结论可采用LC-MS/MS法检测达必佳和达菲林的Beagle犬体内药动学参数。两药在Cmax、AUC(0-t)与AUC(0-)有差异,但两者血药浓度维持在最低定量限(LLOQ)以上的时间均达到28 d以上。
