Estudo de toxicologia clínica de três fitoterápicos à base de associações de plantas, mel e própolis em voluntários sadios

Abstract

Melparatosse®, Calmatoss® e Saratosse® are phytomedicine products used for the treatment of several pulmonary diseases. Their compositions include medicinal plants, as well as honey and propolis, as syrups. The study aimed to assay these formulations for their safe use in humans. It consisted of three open clinical trials with 26 healthy volunteers of both sexes each one. The vontunteers age ranged from 18 to 49 years old and they received an oral dose of 15 mL of one of these three products for uninterrupted 21 days- except Saratosse®, 28 days -, four times a day. To get in to the trials, the volunteers had to be considered as healthy after clinical evaluation, physical examination and laboratory tests. The laboratory tests included hematological, biochemical and serological analysis. This evaluation was repeated at the end of every week of treatment, and seven days after the last administration. Clinical, electrocardiographic and laboratory tests did not show any evidence of toxic signs in the various organs and systems studied. Adverse events related at the studies were: tachycardia, dyspnea, asthenia, cough, dizziness, increase of transaminase, dysuria, muscle pain, constipation (n=1); pyrosis, flatulence, dysmenorrhea, dental pain, malaise (n=2); nausea, migraine, drowsiness (n=3); diarrhea, epigastralgy, abdominal pain (n=4); headache (n=9); flu (n=9); pharyngitis (n=11). All the events were classified as possible or not related to the phytomedicines assayed. Those events were well tolerated by all volunteers.
