| Measure | Time frame |
|---|---|
| Pharmacokinetic variable - Plasma levels of Zidovudine (values expressed in mcg/mL): Measuring time: At the beginning and at 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6 and 8 hours after administration. | — |
Secondary
| Measure | Time frame |
|---|---|
| Presence of adverse events-AE - distribution frequency for the appearance of adverse events (Yes, No), - type of event (name of the AE), - duration (time from appearance to end of the event), - severity (severe, non-severe), - intensity of AE (grades 1-5), - causal relationship (remote, possible, probable, very probable), - result of AE (recuperate, improvement, persist or sequels), - attitude concerning the studied treatment (without changes, dose modification, temporal or definitive treatment discontinuation)). Measuring time: At each administration and during the whole study. Clinical laboratory tests - Hematology (hemoglobin, hematocrit, white blood cells counts, globular sedimentation rate, platelet count) and - Biochemistry (glycemia, cholesterol, triglycerides, transaminases, alkaline phosphatase, urea, creatinine) determinations (numerical values as units of measurement for each determination). Measuring time: At baseline and end of the study. - Vital signs (body temperature in degrees centigrade, heart rate in beats / minute, blood pressure in mm Hg and respiration rate in breaths per minute). Measuring time: Prior to administration of the tablets, during the first 4 hours after administration, and at the end of each period. | — |
