Brief summary

The aim of our study was to assess the clinical efficacy and safety of the drug Imescard compound water smartweed, adrenalin and hamamelis ointment in the treatment of hemorrhoidal disease in adults, in a randomized, double-blind, placebo-controlled clinical trial.

Detailed description

The drug Imescard compound water smartweed ointment is currently registered at the brazilian National Sanitary Surveillance Agency (ANVISA) as a topic hemorrhoidal treatment. It's composed by adrenalin, which produces vasoconstriction, benzocaine, an anesthetic, hamamelis, which is believed to have a desiccative and astringent activity, and water smartweed (Polygonum hydropiperoides), commonly used in the treatment of this condition, with, however, little or no evidence other than tradition to support its use. The aim of this study was to assess the clinical efficacy and safety of this drug in the treatment of hemorrhoidal disease in adults, in a randomized, double-blind, placebo-controlled clinical trial. Sixty healthy volunteers with ages between 18 to 70 years old who presented with 2nd to 4th degree hemorrhoids were enrolled after clinical and laboratory evaluation (day 0) and then randomized (day 1) to receive either the Imescard ointment after waking up, after evacuations and before bedtime, for 5 days, or placebo, with the exact same appearance and posology. At followup (day 8), patients underwent new clinical and laboratory evaluation. Main outcome was the percentage of patients with 50% improval of symptoms, assessed by a diary containing symptom questionnaires concerning every day of treatment. Secondary outcomes were mean scores of the symptom questionnaires, life quality improval assessed by WHOQOLbrief at days 1 and 8 and adverse effects evaluation.
