Quality Assurance (QA) is a wide concept and covers all aspects that could have an impact on the quality of prescribed pharmaceutical products. The objectives of QA are to ensure that the prescribed medicine competently provides the desired effect to the person taking it; to protect patients from accidentally being administered an incorrect or contaminated medication; and to ensure medicines comply with the regulation.
Pharmaceutical Quality Systems (PQS) consist of eight pillars, which are designed to provide high quality finished pharmaceutical products, with QA and PQS working together in synergy. Pharmaceutical companies strive to provide high quality products to enable them to enhance their reputation, maximize profit and to provide high quality drugs to humans and animals. To meet these targets, they rely on well-designed PQS, which involve the coordination of quality through processes, with the aim of producing finished products of the highest quality.
