Within one week of the screening visit, subjects who meet all inclusion criteria and none of the exclusion criteria will receive Coated Nifedipine 12 mg Suppository X2 a day (BID) (24 mg/day total) for a period of 8 weeks.
During this period, 4 study visits (at 0, 2, 5, and 8 weeks) will take place.
Study medication will be administered BID (in the morning and in the evening).
In addition to receiving study medication, subjects will be maintained on a standard treatment for Anal Fissure: sitz baths, high fiber diet.
