This document discusses quality control procedures for raw materials, in-process controls, and finished drug products. It outlines various tests and checks done at different stages of production to ensure product quality and purity. These include sampling and testing of incoming raw materials, in-process checks of attributes like tablet weight and size, and final testing of finished products prior to release. The goals of quality control/assurance programs are to ensure consistent active ingredient amounts within limits, use of ingredients meeting specifications, minimized variability between doses, and high purity and stability of finished products.
