What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Description

Norprolac is a medication prescribed to treat a condition called hyperprolactinemia, which is characterized by high levels of prolactin. People with hyperprolactinemia may experience various symptoms, such as irregular menstrual periods, infertility, and breast milk production in non-pregnant women. Men may experience irregular breast growth.

The active ingredient in Norprolac is quinagolide, which is a dopamine agonist. Norprolac binds to dopamine receptors in the brain and reduces the production and release of prolactin. Reduced prolactin helps to alleviate symptoms.
