每日一次的Razadyne ER可用于治疗轻至中度的早老性痴呆
美国食品和药物管理局近期通过了Razadyne ER可用于治疗轻至中度的早老性痴呆。Razadyne ER含有的速率控制膜成分能令药物在24小时内缓慢释放,同时含有的速效和缓释剂量只需每日服药一次,大大方便了患者用药及家人的照料。
早在2001年2月,美国食品和药物管理局就通过了名为REMINYL(R)的制剂,该药成分与Razadyne ER相同,每日服用两次。如今,有约200万早老性痴呆患者服用REMINYL(R)。2005年4月,REMINYL(R)改名为Razadyne ER,临床研究表明,每日只需服用一次的Razadyne ER在疗效、安全性和耐受性方面与REMINYL(R)相近。
一项有965名患者参与的临床试验发现,治疗6个月后,服用Razadyne ER患者的认识改善要较安慰剂组显著(根据“早老性痴呆评估量表”得分),此外,该组患者“早老性痴呆合作研究及日常生活能力”(ADCS-ADL)量表得分也明显优于安慰剂组。在该研究中,Razadyne ER的初始剂量为8mg/天共服用4周,随后增加至16mg/天共4周,之后根据患者的耐受情况及药物的安全性,酌情可将剂量增至24mg/天。约有80%的患者完成了该项研究。
恶心、呕吐、腹泻、食欲减退及体重减轻是Razadyne ER最常见的副作用,但这些副反应通常是轻微且暂时的。需要指出的是,并不是所有的患者都适用Razadyne ER。部分患者会出现心率的减慢,从而发生昏厥。有的患者在服用了非甾体类抗炎药后会引发诸如胃溃疡等严重的胃肠道疾病。
