Summary
This is an open label, dose-finding study. Approximately 8 healthy subjects will be
participating in this study.
Within one week after the screening visit, subjects who meet all inclusion criteria and none
of the exclusion criteria will enter a one day treatment period. During this period, 4 anal
manometric studies will take place. Study medication (Coated Nifedipine suppositories at
various doses) will be administered at pre-determined intervals. During the study, blood
samples will be obtained for plasma Nifedipine analysis.
Clinical Details
Official title: An Open Label Study to Examine the Effect of Coated Nifedipine Suppositories on Anal Pressure in Healthy Subjects
Study design: Single Group Assignment
Primary outcome: The primary efficacy parameter is change in Resting Anal Pressure from baseline.
Detailed description:
After detrminig baseline resting anal pressure with a manometric test, coated Suppositories
will be administered intra rectally. Subjects will take rectally a total of 3 Coated
Suppositories per study. 90 minutes after each coated suppository insertion this suppository
will be removed and a amnometric study will be performed:
The first dose will contain 4 mg of Nifedipine and the manomentric measurement performed
afterwards will be used to determine baseline anal pressures.
The second dose will contain 12 mg of Nifedipine. The third dose will contain 24 mg of
Nifedipine. The primary efficacy parameter is change in Resting Anal Pressure from
baseline.
The secondary efficacy parameters include the following:
- The ratio of change in anal pressure to plasma Nifedipine level.
- The ratio of change in anal pressure to change in blood pressure.
- The ratio of change in anal pressure to change in heart rate.
