Thanks for emailing that article!

All medications available on the market have a generic name.
When a pharmaceutical company first develops a new drug, it gives the drug a generic name (or 'chemical name'). The company then gives the drug a brand-name as part of its marketing plan.
The generic version becomes available when the brand-name drug's patent protection expires.
