“D” – Generic and Brand Name Drugs

Generic drug – is a drug with proven pharmaceutical, biological and therapeutic equivalence to the original. That is, a drug having the same composition of active ingredients, dosage form and effectiveness as the original drug, but do not have patent protection.

May differ from the original drug in composition of excipients. Placed on the market after expiry of patent protection the original drug. The most common is now called “Generic”.

In the pharmaceutical industry there are 2 groups of drugs:

  • Original drug (Brand-name Drugs)
  • Generic drug.

Branded drugs are expensive, the price of generics are much cheaper than original drugs .

Original drug – this is a new development pharmaceutical company, which it was first discovered, synthesized, and protected by a patent for many years (usually 10+). During this period, the drug produces only this company. The original drug is often unique in its kind and has no analogues among competitors, so the pharmacy you will not be able to pick up analogue remains valid patent protection.

When patent protection is removed and appear analogues (Generics), this is the original brand-name drug will cost more than all other generics drugs

The essential requirement for the sale of generics – proven pharmaceutical, biological and therapeutic equivalence to the original. The active ingredient original brand drug and the generic drug are always the same, but the dosage of the active substance and appearance of drugs can vary at the discretion of the pharmaceutical company.
