The Excipients between Effects and the Side Effects

Abstract

Most of the medicines contain excipients. They are added for a number of purposes and can improve product performance, including enabling formulations, the patient s acceptance and compliance,\xa0There are numerous examples of typical excipients affecting drug absorption. For example, carbohydrates and phosphoric acid delay gastric emptying, due to their caloric content and pH, respectively, and affect the saturable absorption of riboflavin and the saturable biotransformation of salicylamide,\xa0The effect of reactions between the active pharmaceutical substance and the excipients could be a reduction in drug concentration, but at the same time unknown structure and biological activity would appear and, in the worst case, this could lead to adverse effects, the aim of this review is to explore excipients function and the possible side effects associated with it . conclusion: the potential adverse effect of the excipients should not be underestimated and a periodic review and follow up of side effects that may appear and occur after a drug administration should not be limited to the active medication in the drug formula but also the excipient should be taken into account.
