俄科技网11月29日载文，解释咖啡如何影响药效。文章说，对许多人而言，无法想象没有咖啡的生活会是怎样，但很少有人去考虑喝咖啡成瘾的副作用。遗憾的是，咖啡会影响人体对药物的吸收，一方面咖啡会抑制吸收某些药物，另一方面某些药物会加强咖啡的作用。在许多情况下，咖啡因同药物发生相互作用，而且咖啡的其它成分也起着重要的作用。研究表明，有几十种药物，包括抗抑郁药、雌激素制剂、治疗骨质疏松和甲状腺病的药物等，受咖啡的影响，会改变药效。2008年进行的一项研究发现，如病人在服用甲状腺素前或后不久喝了咖啡，药物吸收效果会降低55%。其他研究结果还表明，咖啡会降低人体对药物阿仑膦酸钠（骨再吸收抑制剂）的吸收率60%。此外，咖啡会降低妇女体内的循环激素水平，包括雌激素。奇怪的是，一些处方药会加强咖啡及咖啡饮品的效果。这些药物包括抗抑郁药、抗生素和口服避孕药，会抑制酶，如：已知的有CYP1A2，即有助于人体吸收咖啡因。因此，咖啡因在人体内的停留时间会比平常情况下更长。实验证明，对于服用避孕药的妇女，咖啡因在其体内停留的时间比其他人多4个小时。
