Propionibacterium extract gel
0.4% glyceryl trinitrate ointment
The Propionibacterium extract gel is a topical product that protect the skin and mucous membranes from external agents. Its film forming property on the epidermis helps reduce inflammation, itching and pain, while the adjunct of antioxidant ingredients helps promote the healing process. Patients were instructed to squeeze out from the aluminium tubes containing the Propionibacterium extract gel, 3 grams of gel (3 cm), applying it twice a day for 40 days in the distal anal canal and perianal area.
0.4% glyceryl trinitrate ointment is a well-known nitric oxide donor which promotes fissure healing by decreasing resting anal pressure and increasing anoderm blood flow, via the stimulation of the intracellular cyclic GMP resulting in a consequent reduction in cytosolic calcium. The success rate is variable, with 28% of patients experiencing transient headache often leading to drug discontinuation and poor compliance to treatment. Patients were instructed to squeeze out from the aluminium tubes containing 0.4% glyceryl trinitrate ointment approximately 1.5 mg of the ointment applying it to the distal anal canal and perianal area with a gloved finger, every 12 hours for 40 days.
