Pharmaceutical manufacturers produce medicines and related medicinal products for use in human or veterinary healthcare. They may make active pharmaceutical ingredients, which provide a medicine's therapeutic effect, or turn these ingredients into finished products such as tablets, capsules, powders, creams, ointments, liquids, inhalers and injectable medicines. Some businesses specialise in particular dosage forms or stages of production, while others manufacture a range of products. Work typically includes developing or adapting formulations, sourcing and handling ingredients, operating production equipment, and carrying out quality checks on materials and finished batches. Manufacturers may also provide contract manufacturing, packaging, labelling and storage services for other organisations.
