The ASTM E55 Cleaning Team has developed and balloted a new standard practice for calculating safe and scientifically justifiable limits for residues found after cleaning processes. This is the first comprehensive guide to setting limits for use in cleaning validation that includes all types of chemical residues, bioburden residues, endotoxin residues, and visual residues.
Preformulation testing encompasses all studies performed on a new drug compound in order to produce useful information for subsequent formulation of a suitable drug dosage form. There is preformulation across the stages of drug discovery, early development, and late development. The route of administration dictates what is important.
