El cannabis en el dolor crónico ¿una indicación respaldada por evidencia científica?
Resumen
Las controversias del cannabis medicinal se basan en múltiples factores. Mientras la legalidad de su uso es respaldada por algunas leyes gubernamentales, la desaprobación de parte de las agencias controladoras de medicamentos más importantes del mundo permanece constante. Se plantea a la fecha si hay evidencia científica fiable y actualizada que desapruebe el uso del cannabis para el dolor crónico. Para esto se utilizó herramientas de búsqueda como Pubmed, Google Scholar y Science Direct para la revisión de la literatura en internet. Las conclusiones de más de 30 artículos encontrados en la web se asemejan en la determinación de la gran necesidad de mayor evidencia científica para reafirmar la seguridad y confiabilidad del uso del cannabis para el dolor crónico incluyendo el dolor musculoesquelético, el relacionado con el cáncer, el neuropático, el de tipo y origen inespecíficos. Se revisaron también los efectos secundarios, las interacciones medicamentosas, la estandarización de embalaje y el control y vías de administración. Debido a la escasez de estudios clínicos bien diseñados con muestras sustanciales y tiempo de duración, factores imprescindibles para la calidad y fiabilidad, se concluye que no existe actualmente evidencia científica para aprobar o desaprobar su uso con fines médicos.
