An anal fissure is a small tear in the anal canal lining that causes pain and bleeding with bowel movements. Fissures are common in the general population, but are often confused with other anal conditions, such as hemorrhoids.
Anal Fissures typical cause sharp pain during a bowel movement that may last from several minutes to a few hours. Patients may also notice bright red blood with bowel movements. Some patients with anal fissures may have little to no pain between bowel movements. Many patients are fearful of having a bowel movement and may try to avoid it because of the pain.
Fissures are usually caused by trauma to the inner lining of the anus from a bowel movement or other stretching of the anal canal. A hard, dry bowel movement is typically responsible, but loose stools and diarrhea can also cause fissures. Treatments of anal fissures are aimed at softening stools and relaxing the anal sphincter muscle to promote healing.
Medications may be prescribed to allow for relaxation of the anal sphincter muscles (nifedipine, diltiazem). These are typically creams that require a specialized (compounding) pharmacy to make. Rectiv, an NTG, can also be prescribed by a physician.
The only way to stop fissure pain is to relax the internal sphincter muscles. Most fissure pain is caused when the anal sphincter spasms during a bowel movement. Fissure medications such as Diltiazem, Nifedipine and Nitroglycerine creams are designed to relax the sphincter muscle. When the sphincter muscle relaxes, the fissure pain goes away.
Yes, this is the way most medications are indicated for use. Medication delivered directly to the anal mucosa surrounding the anal sphincter muscle is more likely to be absorbed effectively and lead to greater sphincter relaxation.
DoseRite provides a system that provides consistent dosing and delivery of medication to the correct location every time. Patient compliance over the prescribed treatment period (6 weeks) is essential.
DoseRite helps to relax the anal sphincter muscles allowing the fissure to heal over time. We recommend a 6-week treatment regimen with the medication prescribed by your physician.
