The pharmaceutical industry uses a very large variety of raw materials and hundreds of ingredients can go into the manufacturing of a single product. It is often difficult for a pharmaceutical manufacturer to have in-house testing facilities and capabilities for all the ingredients and products.
A great deal of effort is spent at establishing specifications for the active ingredient and that of the finished product during a product’s development cycle. Specifications for the raw materials must also be established. Failing to do can result in manufacturing delays and production lot failures. Laboratory testing of pharmaceutical products ensure a consistent level of quality, as well as safety.
