The objective of this experimental study has been to evaluate the possible hypotensive, diuretic and toxic effect of aqueous extract of Calceolaria myriophylla Kraenz (zapatilla). Material and Methods: used albino rats male Holtzmann race for the determination of the effects, after one week of adaptation was measured basal systolic, diastolic and mean pressure. For the determination of the hypotensive effect the induction was realised with the administration of N-nitro-L-Arginine Methyl Ester (L-NAME) to doses of 40 mg/kg/día by oral route during 05 days and again the arterial pressure was measured postinduction, was divided in 06 groups of 08 animal; group positive control (L-NAME) and negative control (distilled water), experimental groups to 50 doses of mg/kg, 100 mg/kg, 200 mg/kg and enalapril to 25 doses of mg/kg. The treatment was during 30 days being measured the arterial pressure every 5 days. The diuretic effect was evaluated using rats normotensas distributed in 05 groups of 09 animals; group control (distilled water), groups to 50 doses of mg/kg, 100 mg/kg, 200 mg/kg and furosemida to 10 doses of mg/kg. The evaluation of the antioxidant activity was realised to the groups determined in the hypotensor effect. The study of the toxic effect was determined in the test to doses repeated by 60 days at hematological, biochemical and anatomopatológico level in normotensas rats distributed in 03 groups of 06 animal; using 100 doses of mg/kg, 200 mg/kg and a group control (distilled water). Results: The aqueous extract of Calceolaria myriophylla Kraenz induced hypotensive and diuretic effects to the doses indicated by oral route. The aqueous extract increased the serum levels nitric oxide and decreased serum levels of malondialdehido. No toxic effect in the test to doses repeated by 60 days. Conclusions: These results suggest that oral administration of aqueous extract of Calceolaria myriophylla Kraenz exhibited hypotensive, diuretic, antioxidant actions without toxic effects.
