The phrase "perianal fissure rectal treatment" is an indication-based descriptive category rather than a formal, standard pharmacologic drug class Clinically, it refers to topical and local agents—most notably organic nitrates like nitroglycerin ointment, calcium channel blockers such as diltiazem and nifedipine, and local anesthetics—administered to manage tears in the distal anal canal These agents primarily work by relaxing the hypertonic internal anal sphincter muscle, thereby reducing resti...

The phrase "perianal fissure rectal treatment" is an indication-based descriptive category rather than a formal, standard pharmacologic drug class Their major clinical application is in proctology and colorectal medicine for the conservative management of acute and chronic anal fissures

Clinically, it refers to topical and local agents—most notably organic nitrates like nitroglycerin ointment, calcium channel blockers such as diltiazem and nifedipine, and local anesthetics—administered to manage tears in the distal anal canal

These agents primarily work by relaxing the hypertonic internal anal sphincter muscle, thereby reducing resting anal pressure, improving microvascular perfusion to the ischemic anoderm, and relieving defecatory pain to facilitate tissue healing
