Introduction
Under normal circumstances, stearic acid has pharmaceutical functions such as serving as a carrier, sustained-release and controlled-release agent, enteric coating agent, and base for topical formulations. It should be used according to medical instructions. Although stearic acid has roles in pharmacy and medicine, it is typically part of drug formulation rather than a direct ingredient in daily care products. When using medications containing stearic acid, follow the doctor's recommendations.
通常情况下,硬脂酸的药剂学作用有Medicine制剂中的载体、缓释和控释剂、肠溶剂、外用制剂的基质,需遵医嘱使用。
1.Medicine制剂中的载体:硬脂酸常被用作Medicine制剂的载体,可以帮助改善Medicine的溶解性和生物利用度。在制药过程中可以作为辅助成分,有助于提高Medicine的稳定性和吸收性。
2.缓释和控释剂:硬脂酸在制备控释Medicine剂型中具有重要作用。通过与其他药剂学成分的结合,硬脂酸可以帮助延长Medicine的释放时间,实现Medicine在体内的缓慢释放,从而提高药效的持久性。
3.肠溶剂:在一些口服制剂中,硬脂酸可以被用作肠溶剂,有助于保护Medicine免受胃酸的影响,使其在小肠中释放,提高Medicine的吸收效率。
4.外用制剂的基质:硬脂酸在外用制剂中,如药膏和软膏中,可以作为基质成分,提供Medicine局部传递的适当质地和质感。
虽然硬脂酸在药学和医学中有其作用,但通常是Medicine制备中的一部分,而不是日常Nursing的直接成分。在使用含有硬脂酸的Medicine时,应按照Doctor的Recommendation使用。
