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.

What is Hypertension?

Hypertension, the clinical term for high blood pressure, is defined as having continued blood pressure readings of a systolic pressure of 130 mm Hg or higher, or a diastolic pressure of 80 mm Hg or higher. Diagnoses include Stage 1 and Stage 2 hypertension, as well as hypertensive crisis, which requires immediate medical attention. Untreated hypertension can lead to stroke, heart failure, kidney damage, vision loss, erectile dysfunction, and memory loss. Excess dietary sodium is a major contributor to worsening hypertension in adults.
