Recombinant technology or genetic engineering is a modern method used for the synthesis of therapeutic agents. The central theme of recombinant technology is the process of gene cloning which consists of the production of a deÞ ned fragment of DNA and its propagation and ampliÞ cation in a suitable host cell. Drugs developed by recombinant technology or genetic engineering are known as biologics, biopharmaceuticals, recombinant DNA expressed products, bioengineered, or genetically engineered drugs. A current list of various products developed by recombinant technology includes erythropoietin, coagulation modulators, enzymes, hormones, interferons, interleukins, granulocyte colony-stimulating factors, anti-rheumatoid drugs, and various other agents like TNF, becaplermin, hepatitis-B vaccine, antibodies etc. This article provides general as well as recent pharmacological information on different aspects of recombinant drugs that may be useful for their better understanding by users and health care professionals.
Key words: Biologics, erythropoietin, interferon, interleukins, insulin, thrombolytic enzymes.
