Description: 0.4% Nitroglycerin ointment is an intra-anal formulation of nitroglycerin (glyceryl trinitrate) indicated for the treatment of chronic anal fissure pain.black triangle Nitroglycerin is a nitric oxide (NO) donor, which reduces the increased anal canal pressure caused by a hypertonic internal anal sphincter, improving anodermal blood flow. A twice-daily 375 mg application of 0.4% nitroglycerin ointment, delivering a daily nitroglycerin dose of 3mg, significantly increased the rate of decrease in mean visual-analogue-scale pain scores, recorded daily, versus placebo (actual vehicle) over the first 3 and 8 weeks of treatment in patients with chronic anal fissure pain participating in randomised double-blind trials. Most recipients of 0.4% nitroglycerin ointment experienced headache, which was transient but severe in 20-25% of patients in randomised double-blind trials; however, compliance was generally good with few study withdrawals.
