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.

Caverject Impulse is a medication designed to address difficulties with male sexual function, commonly known as erectile dysfunction. Its primary mechanism of action involves facilitating the circulation of blood into the penis, thereby enabling the achievement and sustenance of an erection. As a vasodilator, Caverject Impulse promotes the dilation of blood vessels, enhancing blood flow to the penile region.

When evaluating treatment options for Erectile Dysfunction (ED), it is essential to consider factors such as effectiveness and the Caverject Impulse cost.
