Generic Names And Medications

c. The Trade Name: The name devised by the manufacturer to sell the drug commercially is known as trade names. These are usually very non-technical, easy to remember and often associated with the desired output of the drug rather than its physical and/or chemical composition. A drug may be known in the masses by its trade name rather than its generic name.

So a drug typically has only one single chemical and generic name but it very well can have more than one trade name, depending on type and number of companies manufacturing it.
