What is the definition of proxetil or how has this word been derived?

The term "proxetil" is a pharmaceutical suffix or part of a drug name. It is derived from the chemical compound propylene glycol and is often attached to the end of drug names. Proxetil is used to create prodrugs, which are biologically inactive compounds that are converted into active drugs inside the body. The addition of the proxetil suffix to a drug molecule can modify its absorption, distribution, metabolism, and excretion properties. This allows for improved bioavailability, increased therapeutic efficacy, or altered pharmacokinetic profiles.
