Are Topical Medications the Key to Healing Anal Fissures?
Published: Jul 10, 2024
Topical medications offer a non-invasive way to treat anal fissures effectively. Learn about the different options and how they work.
Topical Nifedipine
Nifedipine is a topical vasodilator that helps heal anal fissures by relaxing the anal sphincter. Applied as a 0.2 to 0.3% ointment, it increases blood flow and reduces sphincter pressure. Nifedipine is a preferred choice due to its lower risk of side effects compared to other treatments.
Topical Nitroglycerin
Nitroglycerin ointment is another effective treatment that works similarly to nifedipine by increasing blood flow. Available as a 0.4% commercially prepared ointment, it is applied twice daily. While effective, it may cause headaches and should be used cautiously if taken with certain medications.
