ABSTRACT

Los medicamentos homeopáticos y fitoterapéuticos que contienen productos herbarios son cada vez más utilizados, sin embargo, se desconoce el potencial de efectos adversos por parte de los usuarios y personal sanitario. Se reporta el caso de una mujer de 34 años quien consulta por dolor abdominal y náuseas, con alteraciones al ingreso de función hepática con patrón hepatocelular, se descartaron múltiples etiologías y se consideró que pudiera ser lesión hepática medicamentosa secundaria al consumo de medicamentos desde hacía una semana para dismenorrea, y a fitoterapéuticos que consumía de forma crónica, los cuales se suspendieron. A los doce días de su egreso, reingresó por sintomatología similar; se documentó nuevamente perfil hepático con patrón hepatocelular. Al reinterrogatorio, la paciente comentó la ingesta crónica de Valeriana officinalis y Passiflora incarnata, que retomó al egreso hospitalario, por lo que luego de descartar diagnósticos diferenciales, se consideró que el cuadro era inducido por el consumo de dichos medicamentos. Durante la hospitalización se suspendió su consumo, con normalización del perfil hepático. Es importante que los consumidores estén informados sobre los riesgos potenciales de los productos herbarios, sus efectos por consumos prolongados y las implicaciones de la autoformulación.


Homeopathic and phytotherapeutic medicines containing herbal products are increasingly used, however the potential for adverse effects on users and healthcare personnel is unknown. We report the case of a 34-year-old woman who consulted for abdominal pain and nausea, accompanied by hepatocellular pattern on liver function tests. Multiple etiologies were ruled out and it was considered that it could be a drug-induced liver injury secondary to the consumption of medications she had been taking a week prior for dysmenorrhea, and phytotherapeutics that she had been taking for seve-ral years, which were all discontinued. Twelve days after her discharge, she was readmitted due to similar symptoms; a liver profile with a hepatocellular pattern was again documented. Upon further questioning, the patient mentioned a chronic intake of Valeriana officinalis and Passiflora incarnata, which she resumed upon discharge. After ruling out the differential diagnoses, it was concluded that the symptoms of the patient were induced by the consumption of these herbal products. During hos-pitalization, their consumption was suspended, with normalization of the liver profile. It is important that consumers are informed about the potential risks of herbal products, their effects from long-term use, and the implications of self-medication.

ABSTRACT

El sistema opioide, del cual forman parte los peptidos opioides endogenos y sus receptores (Miu, Kappa, delta y ORL), tiene un papel importante en la fisiologia de diferentes sistemas. Existe una creciente evidencia de su participacion en la fisiopatologia de multiples trastornos del sistema nervioso central, endocrino e inmunologico. La modulacion del sistema opioide mediante el uso de antagonistas especificos o inespecificos de sus receptores puede tener un papel terapeutico en el manejo sintomatico de diferentes contextos, incluyendo la intoxicacion aguda por opiaceos, la dependencia a opioides, y la reduccion de reacciones adversas de agonistas opioides utilizados en el manejo del dolor cronico. El presente trabajo tiene como objetivo revisar la farmacologia de los antagonistas opioides especificos e inespecificos, y realizar una actualizacion de sus posibles nuevas indicaciones y usos terapeuticos.


Opioid system, which involved endogenous opioid peptides and their receptors (Miu, Kappa, delta and ORL), has a main role in the physiology of several systems. At the same time, there is cumulating evidence in the role of the opioid system in the physiopathology of several disorders in the central nervous, endocrine and immunological system. The modulation of the opioid system using nonspecific antagonists may have a therapeutic role in the symptomatic management of several diseases, as well as, in the emergency management of opioid analgesic overdose, opioid dependence and to reduce the drug side effects of the opioid agonists used in chronic pain. This paper aims to review the pharmacology of specific and nonspecific opioid antagonists, and update on possible new indications and therapeutic uses of such antagonists.
