Is this describing a “generic drug” situation after a patent expires?
Yes. When a drug’s patent expires, generic manufacturers can usually make and sell the same active ingredient (the same chemical compound) under a different brand/generic name, often at much lower prices. This is an example of generic competition following patent expiration.
What term best fits “develop …” in the sentence?
The sentence is describing the development (or introduction) of generic drugs enabled by patent expiry—often framed as the generic-drug entry phase that follows loss of exclusivity.
Why do prices typically drop after the patent expires?
Once patent protection ends, multiple manufacturers can produce the same medicine, increasing competition. That competition tends to reduce prices compared with the original (brand) product.
How this connects to drug exclusivity beyond patents
Patent expiry is one pathway to generic entry, but some drugs also have other exclusivity protections (for example, regulatory exclusivities). Those can delay the timing of generic launches even after the patent timeline ends—so the “can introduce right away” detail depends on the specific protections involved.
