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.

    What is janumet used for?

    janumet medication Janumet (Sitagliptin/Metformin)

    Janumet medication is used to control high blood sugar. This drug is used with a proper diet and exercise plan and mostly by patients with type 2 diabetes.

    This medicine contains sitagliptin metformin. Sitagliptin works by increasing the substance called incretins that is naturally present in our body. Incretins help in controlling the level of blood sugar by increasing the release of insulin right after a meal.

    Incretins also help to decrease the amount of sugar made by the liver. Metformin helps in restoring the body's proper response to the insulin you produce naturally. It also decreases the amount of sugar made in the liver and absorbed in the stomach and intestines.

    Controlling the high blood sugar level prevents the kidney from being damaged, nerve problems, blindness and sexual function problems.
