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.

Description

Asendin is a prescription medication used to treat Major Depressive Disorder (MDD). It may be prescribed after other antidepressant medications have been tried and failed.

Asendin belongs to the class of antidepressants called tricyclic antidepressants. It works by affecting the neurotransmitters that pass chemical signals between brain cells. 

The neurotransmitters serotonin, norepinephrine, and dopamine are responsible for creating the moods we feel in the brain. Certain people with MDD have low levels of these neurotransmitters, and Asendin helps increase the levels and improve mood.
