Study to Investigate the Absolute Bioavailability of Oral Sylibin
- Conditions
- Healthy Volunteers
- Interventions
- Drug: Legal贸n SIL
- Registration Number
- NCT02633696
- Brief Summary
This clinical trial phase I in healthy volunteers is intended to describe the oral bioavailability of the silybin-phosphatidylcholine complex by calculating the area under the curve (AUC0-? and AUC0-12) after administration of the same dose of oral silybin (AUCo) and intravenous silybin (AUC iv).

Group Intervention Description Legal贸n Sil i.v 350 mg Legal贸n SIL 8 healthy volunteers received 1 vial of 350 mg iv of sylibin lyophilisate for solution for infusion (legalon sil) in two hours (single dose). Silybin-phosphatidylcholine oral 360 mg silybin phosphatidylcholine 8 healthy volunteers received 9 capsules of 40 mg of sylibin each one (360 mg in total) orally.
- Primary Outcome Measures
Name Time Method Sylibin pharmacokinetic parameters: Maximum plasma concentration (Cmax) obtained in the different treatment groups. 1 Month Patient will be hospitalized in the clinical trial unit in order to obtain plasma concentrations previous to the administration of the corresponding dose and at the following times post-administration: : 20min, 40min, 1h, 1h20min, 1h40min 2h, 2h30min, 3h, 4h, 6h, 8h and 12h. Two more plasma concentrations will be obtained at 5 min and 10 mins post- administration of the iv dose. These measures will be calculated in order to describe the bioavailability of oral sylibinobtained in the different treatment groups.

- Secondary Outcome Measures
Name Time Method Sylibin pharmacokinetic parameters:Tmax, obtained in the different treatment groups. 1 Month Sylibin pharmacokinetic parameters:t1/2, obtained in the different treatment groups. 1 Month To evaluate the safety (adverse events, laboratory abnormalities) and tolerability 2 Months To estimate the inter and intraindividual coefficient of variation (CV) 1 Month
