Bioavailability of Tipranavir/Ritonavir Paediatric Solution Compared to Tipranavir/Ritonavir Capsules in Healthy Female and Male Subjects

Relative Bioavailability of 500/200 mg of Tipranavir/Ritonavir Paediatric Solution Compared to 500/200 mg of Tipranavir/Ritonavir Capsules Following Oral Administration and Bioavailability of 500/200 mg Tipranavir/Ritonavir Paediatric Solution Under the Influence of Food in Healthy Female and Male Subjects. An Open-label, Randomised, Single-dose, Three-way Crossover Trial.

Study to determine the relative bioavailability of 500/200 mg of tipranavir/ritonavir (TPV/r) oral solution compared to 500/200 mg of TPV/r capsules following oral administration and to investigate the relative bioavailability of 500/200 mg of TPV/r oral solution with food versus without food.
