Viral Infections

Viruses are intracellular microorganisms that infect people through respiratory passages and intestinal tract. Viral infections can be treated by antiviral agents which are divided into 4 groups:

  • interferon and its derivatives are biologically active agents that stimulate the protection system of body cells to fight viruses and infections. The medical drugs of this group are very efficient in treating chronic viral infections, for instance, viral hepatitis type B
  • anomalous nucleosides that damages synthesis of viruses nucleic acids blocking viral elements expansion. This group of drugs include such medications like Acyclovir, Zovirax and Valtrex which are used for treatment of herpes and shingles. Zovirax and Valtrex are also used to prevent Cytomegaloviral infection and other diseases that may occur after the organs transplantation.
  • Adamantane derivatives like rimantadine that restrain different phases of viral agents' life cycle. Usually used to treat influenza and parainfluenza
  • neuraminidase inhibitors (Tamiflu) that are used to treat swine flu and other flu infections. In the last decades, the flu cases have significantly increased. The flu infection can be treated by 2 major means: prevention through vaccination or chemoprophylaxis with antiviral agents and treatment with antiviral agents. A neuraminidase inhibitor Tamiflu is used to treat influenza type A and B and to prevent seasonal flu epidemic.
  • Substances that destroy viral agents located in the intercellular space (oksolin, bonafton, tebrofen). These substances are used for local and systemic treatment of viral diseases of the skin and internal organs.
  • substances of plant origin that exert antiviral properties.

It is important to know that only your doctor can prescribe you the proper treatment of any viral infection. Very often viral infections occur if immune defenses of the organism are reduced, therefore in many cases the antiviral treatment has to be combined with other medications.
