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.
Theophylline is a lung disease and asthma treatment medication available by prescription and Theophylline is used to prevent wheezing and shortness of breath suffered by asthma and COPD sufferers. Elixophyllin is a xanthine class drug that works by relaxing the muscles around the airway and promotes them opening up more and breathing is made easier. This medication also decreases the lungs’ response to irritants. Patients with asthma using Theophylline will usually still continue to use an asthma maintenance inhaler. Buy Theophylline from Canada and Canpharm and get the best price on it.
Asthma is a lung and pulmonary health disorder where inflammation causes the airways into the lungs to become constricted and limiting the airflow into the lungs for breathing as a result. Symptoms can include shortness of breath, wheezing, and cough. The disorder is manageable, and most sufferers will not have to go for medical attention when having an asthma attack, but for some it may be required based on the severity of their asthma.
