Experimental: The pregabalin group
75 mg twice daily for 3 days, followed by 150 mg twice daily for 3 days during the first week; 225 mg twice daily at week 10; and a tapering regimen at week 12 (150 mg twice daily for 3 days, then 75 mg twice daily for 3 days).
Patients also received routine treatment from gastroenterologists. Patients also received routine treatment from gastroenterologists. Loperamide: 2-4 mg after each loose stool (max 16 mg/day) to reduce stool frequency, though it does not relieve pain.
