Objective: The class of calcium antagonists is consti-tuted by pharmacological agents which inhibit the con-traction evoked by extracellular calcium in depolarized
smooth muscles. While the inhibiting action of calcium
antagonists on the gastrointestinal motility is well
documented, its action on the biliary tract has not been
extensively studied, despite its potential clinical use-fulness. Therefore we investigated the effect of a cal-cium channel blocker (verapamil) on fasting and post-prandial gallbladder volume in normal subjects.
Method: Twenty healthy volunteers participated in this
study. The gallbladder volumes were measured using
ultrasonography. After the baseline measurement was
taken, the volunteers received 80 mg of verapamil (n:10)
or a placebo (n:10) per oral in the morning one h be-fore rescanning. The gallbladder was rescanned in 15
min intervals for 60 min. At the end of this period all
the volunteers received a standard liquid test meal (En-sure), and then scans were performed again.
Results: The administration of verapamil increased the
fasting gallbladder volume to a maximum of 61.2% to
74.2% compared to the baseline (p<0.05) and of 49.1%-62.6% compared to the placebo group (p<0.05). In the
verapamil group significant changes in the postpran-dial gallbladder volumes were observed. The postpran-dial gallbladder volume increased to a maximum of
4.6%-61.2% compared to the baseline (p<0.05) in the
first 30 min. Then it decreased to the baseline value.
The gallbladder volume of the verapamil group was
increased to a maximum of 86.8%-111.7% compared
to the placebo group (p<0.05 and 0.01).
Conclusion: These results demonstrated that verapamil
significantly increased fasting and postprandial gall-bladder volume.
Key words: Calcium channel blocker, verapamil, gallblad-der, contraction, human.
