El síndrome de intestino irritable es un desorden funcional que afecta cerca del 20% de la población.
Un número considerable de compañías farmacéuticas tienen nuevas drogas en desarrollo para tratar a estos pacientes.
Sin embargo antes que estas terapéuticas sean adoptadas en la práctica diaria es importante evaluar las evidencias que sustenten la efectividad de las drogas que estan actualmente disponibles.
El propósito del presente trabajo es revisar y evaluar los ensayos clínicos controlados y aleatorizados que han sido publicados para examinar la efectividad clínica de las intervenciones para el síndrome de intestino irritable.
