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.

Nitrolingual 0.4mg Pump Spray is a nitrate-based medication primarily used to treat episodes of angina pectoris (chest pain). Glyceryl Trinitrate- the active ingredient, works by relaxing and widening blood vessels, allowing more blood to flow to the heart muscle and reducing the heart's workload. This spray provides rapid relief from angina attacks and can also be used as a preventive measure before activities that might trigger angina pain.

Before you buy Nitrolingual Spray, it is important that you talk to your healthcare provider about potential side effects and Nitrolingual price.
