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 dulera inhaler used for?

    Dulera Inhaler 100mcg

    Dulera Inhaler

    Dulera inhaler is used to prevent symptoms of asthma such as shortness of breath, wheezing, etc. It contains two medications that are mometasone furoate and formoterol. Mometasone furoate is a corticosteroid. It helps in reducing inflammation in the airways and acts upon inflammation-causing substances in the body such as histamine. Formoterol works by relaxing the muscles that surround the airways. This helps in opening up the airways. Formoterol also keeps cells mast cells from sending out chemical signals to the brain that trigger inflammation, helping to keep the airways less sensitive.

    You can purchase the medicine Dulera Inhaler easily from Canada Pharmacy.
