Suspension pH 1.6 40 mg | ||||||||||||
Arm description |
For the acidified suspension, 1 mL of Noxafil® (40 mg posaconazole as such, which corresponds to 10% of the typical therapeutic dose) was dispersed in 240 mL of tap water acidified to pH 1.6 with HCl (70% of posaconazole in solution). This suspension was intragastrically administered to healthy subjects. | ||||||||||||

Suspension pH 7.1 40 mg | ||||||||||||
Arm description |
For the neutral suspension, 1 mL of Noxafil® (40 mg posaconazole) was dispersed in 240 mL of tap water (pH 7.1; 2.3% of posaconazole in solution). After intragastric administration, antral and duodenal fluids were aspirated for 3 h; samples were taken at 2, 7, 15, 25, 35, 45, 55, and 60 min during the first hour and every 15 min for the next 2 h. The sampling volumewas kept as small as possible (<4mL per time point). Immediately after aspiration of fluids, pH was measured (Hamilton Knick Portamess®, Bonaduz, Switzerland) and the determination of dissolved and total posaconazole was initiated. Blood samples were collected in heparinized tubes (BD Vacutainer systems, Plymouth, UK) at 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 7, 8, and 24 h after intragastric administration. Blood samples were centrifuged (2880g, 10 min, 4°C) and the obtained plasma was stored at -26°C until analysis. | ||||||||||||

Solution pH 1.6 20 mg | ||||||||||||
Arm description |
In an additional condition (no blood sampling involved), posaconazole as such was intragastrically administered as a solution in order to assess intestinal posaconazole precipitation without the potential impact of accelerated nucleation due to the presence of solid particles from the suspensions. The solution was prepared by dissolving 0.5 mL of Noxafil® (20 mg posaconazole) in 240 mL of tap water acidified to pH 1.6. Analogous to previous test conditions, antral and duodenal fluids were aspirated for 3 h, followed by pH measurement (Hamilton Knick Portamess®) and determination of dissolved and total posaconazole concentrations. Blood samples were not collected. | ||||||||||||

Data Presentation and Statistical Analysis | ||||||||||||||||
Statistical analysis description |
Intraluminal concentration-time profiles are presented as mean ± standard error of the mean (SEM) for five subjects. Pharmacokinetic parameters (plasma and duodenal Cmax tmax, and area under the curve [AUC]) are reported as mean ± SD. Test conditions were compared using a paired t-test (after logarithmic transformation of Cmax and AUC); differences were considered statistically significant at p < 0.05.
