All volunteers will be divided into three groups. Initially, Group I (5 volunteers) will be included in the study. As soon as the interim results of safety tests (complete blood count, clinical biochemical analysis, clinical urine test and clinical examination of the general state of health) obtained on Day 7 are evaluated, the Investigator will make decision on whether to enroll the second group (5 individuals) to assess the product used in a dose of 600 mg. After the interim safety evaluation on Day 7, additional 15 volunteers will enter the study to receive the product in a dosage regimen proposed for use in clinical practice.
