- Public TitleLybrido Food effect study Voedsel effect onderzoek naar Lybrido
- Scientific TitleA randomized, open label balanced two period, two-treatment, two-sequence crossover study to evaluate the effect of food on the pharmacokinetics of sildenafil after a single oral administration of Lybrido in healthy female subjects
- hypothesisPrimary objective
1. To determine the effect of food on the pharmacokinetics of sildenafil administered as the Lybrido formulation
2. To determine whether >90% of the testosterone content is released after maximally 90 seconds after sublingual dosing
Secondary objective
1. To evaluate the safety and tolerability of a single dose of Lybrido under fasted and fed conditions
- Healt Condition(s) or Problem(s) studiedSexual function, Sexual dysfunction
- Inclusion criteria1. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legal representative) has been informed of all pertinent aspects of the study
