What is Generic?

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.

Nifedipine is a medication classified as a calcium channel blocker and is prescribed for the treatment of hypertension (high blood pressure). It can be used alone or in combination with other medications to effectively manage high blood pressure, which in turn helps reduce the risk of strokes, heart attacks, and kidney problems. Additionally, this medication is utilized for certain types of chest pain (angina). It can enhance exercise tolerance and decrease the frequency of chest pain episodes.
