Question - What are drug excipients?
Answer- The cited article states “Excipients are used ubiquitously to formulate drugs. Ranging from detergents like steroyl phosphocholines, to wetting agents like benzalkonium chloride, to stabilizers like cellulose to dyes like acid blur, to sweeteners like aspartame, excipients are crucial to drug solubility and permeability, stability, palatability and delivery. Whereas it is the active ingredient that is responsible for drug pharmacodynamics, without excipients few drugs would achieve the exposure needed for efficacy”. (Irwin JJ et al.
