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.

  • Product Details


    Twynsta is a prescription medication that helps to manage blood pressure. With a combination of telmisartan and amlodipine as its active ingredients, Twynsta provides a dual approach to hypertension control.

    Telmisartan and amlodipine, the main ingredient of Twynsta, work synergistically to address high blood pressure. Telmisartan belongs to the angiotensin II receptor blocker class, relaxing blood vessels to improve blood flow. Amlodipine, a calcium channel blocker, further aids by reducing the workload on the heart and enhancing blood vessel dilation.


    The usual starting dose is telmisartan-amlodipine 40-5 mg. The dose can be increased to a maximum of 80-10 mg.


    The active ingredients in Twynsta are telmisartan and amlodipine.
