What Happens After Patent Expiration?

Once a drug's patent expires, it opens the door for generic manufacturers to produce and sell their own versions of the medication. This typically leads to increased competition and lower prices for consumers. Benzonatate is currently available as a generic drug.

Why Are Generic Drugs Important?
