All subjects were screened for eligibility to participate in the trial. Subjects who meet the inclusion criteria will be considered eligible to participate in the study. Subjects who meet one or more of the exclusion criteria will not be considered eligible to participate in the study.

Participants by arm

ArmCount
REF-T
The subjects received the reference treatment (REF) which was 20 milligram (mg) of hyoscine butylbromide (trade name: Buscopan®, 2\*10mg) followed by a washout period of 7 to 14 days followed by the test treatment (T) which was 20 mg of hyoscine butylbromide (trade name: Buscapina®, 2\*10mg) followed by a washout period of 7 to 14 days. All medications were administered as a single oral dose in the fasted state via a sugar coated tablet.
