ABSTRACT
Currently used cardiovascular drugs such as nicotinamide, strophanthin, corglycon, curantyl, cavinton, papaverin hydrochloride, nicotinic acid, xantinole nicotinate, isoptin, parmidin and halidor were studied by the program of antiviral drug screening. The majority of them (9 out of 11) were shown to have antiviral activity which was rather individual by its specificity and level. Laboratory strains of 9 viruses inducing the most common infections in man and animals, i.e. Herpes simplex, poxvaccine, influenza, vesicular stomatitis, respiratory syncytial infection, VEE, ECHO. Lassa fever and rotavirus infection were tested. The characteristic feature of the drugs was their high specific activity against the DNA-containing viruses and rotavirus. The three drugs papaverin hydrochloride, strophanthin and corglycon proved to be the most promising. Their antiviral activity was confirmed on a model of herpes infection in mice. The paper discusses whether the phenomenon discovered in the official drugs is important in the therapy of somatic patients.
