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.
Zyflo CR is an asthma treatment medication available by prescription and used to lessen the frequency and severity of asthma attacks. The active ingredient in this medication is Ziluton, and it is formulated to block the formation of leukotrienes that are key contributors to the inflammation that is closing the airway and causing the breathing difficulties that come with asthma. Asthma sufferers can take it as part of a maintenance approach to treating asthma. You can buy Zyflo CR with a prescription here at Canpharm.
