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 .
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Pain | Drug: Vitamin E Acetate ointment Drug: Glyceryl trinitrate ointment | Phase 3 |
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.

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. |
- Pain associated to anal fissure: Visual Analogic Scale [ Time Frame: 8 weeks ]Pain will be evaluated after finishing the treatment, by a Visual Analogic Scale, ranging from 0 (absence of pain) to 100mm (unbearable pain)
- Number of participants achieving the healing of the fissure [ Time Frame: 8 weeks ]Healing, defined as evidence of fissure reepithelization
