Participant Flow

Randomised, single-dose, open-label, two-way crossover trial in healthy volunteers to investigate and compare the relative bioavailability of two formulations of hyoscine butylbromide administered orally as drops (T: test treatment) or as sugar-coated Buscopan® tablets(R: reference treatment).

All subjects were screened for eligibility to participate in the trial. Subjects attended specialist sites which would then ensure that all subjects met all inclusion/exclusion criteria. Subjects were not to be randomized to trial treatment if any one of the specific entry criteria were not met.

Buscopan® Tablet (R)/Hyoscine Butylbromide Drops (T)
Participants administered orally in the morning on Day 1 of period 1 with single dose of 2 sugar-coated tablets of 10 milligram (20 mg) of Buscopan®, followed by 20 mg hyoscine butylbromide drops with dose strength of 2 millilitre (mL) in the morning on Day 1 of period 2, each treatment with 240 mL water. Both treatment periods were separated by a wash-out period of at least 7 days.
Hyoscine Butylbromide Drops (T)/Buscopan® Tablet (R)
Participants administered orally in the morning on Day 1 of period 1 with 20 mg hyoscine butylbromide drops with dose strength of 2 millilitre (mL) orally, followed by single dose of 2 sugar-coated tablets of 10 milligram (20 mg) of Buscopan® in the morning on Day 1 of period 2, each treatment with 240 mL water. Both treatment periods were separated by a wash-out period of at least 7 days.

PRIMARY outcome

Timeframe: Pharmacokinetic samples were collected pre dose at 2 hour (h) and at 0.5, 1, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 6, 8, 10, 14, 24 and 36 h after the drug administration.

Population: Descriptive statistics is based on treated set (TS) and statistical analysis is based on pharmacokinetic (PK) analysis set (PKS). (PKS includes all treated subjects with data for a primary endpoint and without any protocol violation relevant to the statistical evaluation of PK endpoints.)
