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

Premarin (conjugated estrogens) is a medication used to treat many different conditions. The Premarin indications in the package insert include:

  • Moderate to severe vasomotor symptoms due to menopause
  • Moderate to severe symptoms of vulvar and vaginal atrophy due to menopause
  • Hypoestrogenism due to hypogonadism, castration, or primary ovarian failure
  • Breast cancer (palliation) in appropriately selected women and men with metastatic disease
  • Advanced androgen-dependent carcinoma of the prostate (palliation)
  • Prevention of postmenopausal osteoporosis

Premarin works by replenishing estrogen levels. Estrogen is a natural hormone that regulates a variety of bodily functions. During menopause, estrogen levels are reduced and replacing estrogen can help provide symptomatic relief of certain conditions. Increasing estrogen may also be used in the treatment of certain cancers and osteoporosis.
