Businesses dealing in pharmaceutical goods manufacture, source, wholesale or distribute medicines and related products for use in healthcare. Their range may include prescription medicines, over-the-counter remedies, generic and branded treatments, vaccines, medical gases and products for specific areas such as pain relief, allergies or skin conditions. Some suppliers also handle active pharmaceutical ingredients and other materials used in medicine production. Services can include product sourcing, order fulfilment, storage and delivery to pharmacies, hospitals, clinics, care providers or other authorised buyers. Medicines may be supplied in forms such as tablets, capsules, liquids, creams, injections and inhalers, with packaging and product information suited to the intended market. UK medicines are subject to regulation by the Medicines and Healthcare products Regulatory Agency (MHRA); the permissions required depend on the activity, product and supply chain.
