(D) Brand name medications are patented by the manufacturing drug company.
When the patent expires, other pharmaceutical businesses may refer to the FDA for approval to make and sell a generic version of the initial compound. The generic drug company must certify that their product comprises the same active component(s) as the brand name product. They must assure that their generic drug controls the same form (liquid, pill, capsule, inject-able, topical), concentration, and dosage as the primary medication.
