Authorized genericNot sold
There isn’t one. An authorized generic is Pentasa itself, from the same company, sold without the brand name, and usually for less. A regular generic is sold, with the same active ingredient: ask the pharmacy for its price.

Prices change, can differ by store and state, and may depend on the strength and how many you take. With insurance, ask what your plan charges; it can be less.
Regular genericWho makes it
One company sells a generic of Pentasa that the FDA rates a substitute. A pharmacy fills whichever one it stocks. To get a certain maker, ask for it by name; most pharmacies can order it in a day or two.
It’s mostly filled by specialty pharmacies. Your prescriber’s office or insurer can tell you which one to use.
