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.
Coumadin is a medication for blood clot prevention available by prescription, used to prevent thromboembolism, pulmonary embolism, or DVT (deep vein thrombosis). Warfarin, an anticoagulant drug, works by preventing the formation of vitamin-K dependent clotting factors, thus reducing the chance of large blood clots traveling through the arteries of the body and creating the risk of an embolism in major organs. Purchase Coumadin from Canada and Canpharm for the best price.
An embolism is a blood clot that blocks the flow of blood through an artery, creating the risk of oxygen starvation (ischemia) in organs relying on these arteries for oxygen-enriched blood. There are different types of embolisms, including pulmonary (lungs), brain, retinal (eyes), septic, amniotic, air, and fat embolisms. Deep vein thrombosis is the primary cause of pulmonary embolisms, and DVT becomes increasingly common in individuals in poorer health as they age, especially with risk factors like obesity, smoking, and heart disease.
