Pharmacology: The local anesthetic dibucaine hydrochloride prevents or relieves the severe pain sometimes encountered in strangulated haemorrhoids, fissure and perianal hematoma, whilst the corticosteroid acts as a decongestant, anti-inflammatory and anti-pruritic agent and by so doing eliminates itching, inflammation and mucous discharge. The broad spectrum antibiotic, neomycin sulfate, will eradicate most infections which may already be present or arise in lesions of the anorectal area.
