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.

    Mestinon SR Drug Interactions and Uses:

    Mestinon SR is an oral enzyme medicine. Acetylcholine is one of the several neurotransmitters in our body. Neurotransmitters are chemicals that facilitate our cells in communicating with one another. Depending on the organ that it acts on, neurotransmitter produces completely different effects. One necessary function of neurotransmitters is to help with muscle contractions and movement.

    In individuals with myasthenia gravis junction or people treated with neuromuscular obstruction medicines, there is a decrease in the levels of acetylcholine. In such cases, pyridostigmine is used to increase neurotransmitter levels and improve muscular contraction or movement. Pyridostigmine can increase the concentration of neurochemical at myoneural junctions by inhibiting the enzyme; the activator that destroys neurotransmitter.
