What are the differences between brand-name Alphagan P and generic brimonidine tartrate?
Generic medications are required to be therapeutically equivalent to their brand-name counterparts. This means they contain the same active ingredient, dosage form, strength, and route of administration, and they are absorbed into the body at the same rate and to the same extent [3]. The primary difference is usually in the inactive ingredients, such as fillers, binders, and colors, which do not affect the drug's safety or effectiveness [3]. Cost is also a significant difference, with generic versions generally being more affordable [3].
