Application of Vitamin E on Anal Fissure

April 20, 2020 updated by: Jaime Ruiz-Tovar, MD, PhD, Hospital General Universitario Elche

Application of Vitamin E Acetate Ointment vs Nitroglycerin Ointment for the Treatment of Chronic Anal Fissure

Patients were randomized into 2 groups:

  • Vitamin E: Vitamin E ointment will be applied during 8 weeks
  • Nitroglycerin: Nitroglycerin ointment will be applied during 8 weeks

Healing rate of chronic anal fissure in patients receiving Nitroglycerin ointment and subjects patients receiving Vitamin E ointment were evaluated .

Detailed Description

Patients were randomly assigned to experimental and control groups: those patients receiving vitamin E ointment (Experimental Group - EG) and those receiving glyceryl trinitrate ointment (Control Group - CG).

Treatments:

Glyceryl trinitrate ointment (GTO): Commercially available aluminium tubes containing 0.4 glyceryl trinitrate ointment (Rectogesic, proStrakan Group, Galashiels, UK) were purchased from pharmacies. The dosage for all the patients was 375 mg of ointment (containing 1.5 mg of glyceryl trinitrate), applied with a gloved finger to the distal anal canal, every 12 hours for an 8-week period.

Vitamin E acetate ointment (VEA): Commercially available plastic tubes containing VitaminE acetate ointment (Filme Olio, Hulka SRL, Italy) were purchased from pharmacies. The dosage for all the patients was 1ml, applied with a gloved finger to the distal anal canal, every 12 hours for an 8-week period.

Healing rate of chronic anal fissure was investigated.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Vitamin E acetate
Commercially available plastic tubes containing vitamin E acetate ointment (Filme Olio, Hulka SRL, Italy) were purchased from pharmacies. The dosage for all the patients was 1ml of ointment (containing 1100% vitamin E), applied with a gloved finger to the distal anal canal, every 12 hours for an 8-week period.
Drug: Vitamin E Acetate ointment
Application of 1 ml of ointment to the distal anal canal, every 12 hours for an 8-week period.
Active Comparator: Glyceryl trinitrate ointment
Commercially available aluminium tubes containing 0.4 glyceryl trinitrate ointment (Rectogesic, proStrakan Group, Galashiels, UK) were purchased from pharmacies. The dosage for all the patients was 375 mg of ointment (containing 1.5 mg of glyceryl trinitrate), applied with a gloved finger to the distal anal canal, every 12 hours for an 8-week period.
Drug: Glyceryl trinitrate ointment
Application of 375 mg of ointment to the distal anal canal, every 12 hours for an 8-week period.
