Abstract

Although several medicinal potentialities have been described to essential oil and to extracts from distinct parts of Casearia sylvestris plant, and mainly due its toxicity restrictions have been described in specific situations, our objectives are to identify pharmacologically the facilitatory effect in different organic fractions of C. sylvestris leaves, as well as the pharmacodynamic of this effect. Previous studies showed that either aqueous as hydroalcoholic extracts induced a dose-dependent facilitatory effect using mouse nerve phrenic-diaphragm preparation. Thus, the fractioning of C. sylvestris hydroalcoholic extract it will permit to identify which of fractions will exhibit such pharmacological effect aiming the further pharmacodynamic study. The clinical benefits in the search of new facilitatory agents are extensive. Depending on its pharmacodynamic, under neuromuscular junction parameter, it is possible to think in applying to the neuromuscular diseases that induce paralysis, as myastenic syndromes and Myastenia gravis; as an adjuvant in cases of botulin toxin or tetrodotoxin envenomation; as neuromuscular recovers after surgery controlled by the non depolarizing drugs; in chronic obstructive pulmonary diseases, as some examples. Whether these objectives were reached with a natural compound and using a plant which has been extensively studied under several approaches as Casearia sylvestris, the scientific gain will be major.
