Antiviral Drugs: Definition Antiviral drugs are medicines that cure or control virus infections. Purpose Antivirals are used to treat infections caused by viruses. Unlike antibacterial drugs, which may cover a wide range of pathogens, antiviral agents tend to be narrow in spectrum, and have limited efficacy. Description Exclusive of the. Drug-Drug Interactions . The effectiveness of a drug can often be reduced if the action of one drug diminishes the action of another. Since drugs are commonly classified by their mode and mechanism of action, any interaction affecting one drug will usually affect drugs of the same class, either by interfering with their absorption or the way in which the body metabolizes the drug Antiviral drugs are a class of medication used specifically for treating viral infections. Like antibiotics for bacteria, specific antivirals are used for specific viruses. Antiviral drugs are one class of antimicrobials, a larger group which also includes antibiotic, antifungal and antiparasitic drugs Antiviral drugs for children come in the form of pills, liquid, inhaled powder, or intravenous solution. They fight flu by keeping flu viruses from reproducing in the body. Antiviral drugs must be prescribed by a health care provider — they are not available over-the-counter. For treatment, flu antiviral drugs should ideally be started within.
