RESUMO
The study aimed at estimating the pharmacotherapeutic efficacy of medications possessed of antiviral activity, such as ribavirin, cycloferon solution and tablets, in 410 patients with Crimean hemorrhagic fever: The early beginning of therapy (days 1-4 after the onset of the disease) with these drugs reduced the number of severe cases and manifestations of hemorrhagic syndrome. The duration of the disease decreased, the occurrence of intoxication syndrome reduced to a minimum, hemorrhagic rash rapidly disappeared, and the frequency of complications decreased. Adverse events were documented in 5.2% of the patients (n = 15); most of them developed on day 2 after using the drugs, their duration did not exceed 2.2 days. There were no cases of drug withdrawal.
