REQUENA, Daniel et al. Estudio experimental de los efectos producidos por el bromuro de pinaverio y el tegaserod sobre el aparato gastrointestinal en animales de experimentación. Gen [online]. 2007, vol.61, n.2, pp.118-122. ISSN 0016-3503.

Introduction: Diarrhea or constipation was induced in a group of rats by the use of drugs that stimulate secretion or drugs inducing constipation. In these rats pinaverium bromide and tegaserod were used as a drug inducing less bowel movement or as a facilitator of defecacion, respectively. This work has as its main objective to find out until what point can these drugs be used as an efective treatment for irritable bowel syndrome. Methods: 12 adult female rats, Sprague Dowley breed, were used. They were distributed in the following way: 2 as control for diarrhea, 4 of them had induced diarrhea with a phenolphthalein mixture and magnesium sulphate; 2 with Tegaserod and 2 with Pinaverium Bromide. In constipation, 2 rats were used as control, 4 of them were administered loperamide to induce constipation, and 2 were treated with Tegaserod and 2 with Pinaverium Bromide. Results: Rats with Diarrhea: With respect to these rats, the variations in weight obtained among controls and the medicated group were highly significant, indicating that both drugs improved their pathological condition. Rats with Constipation: With respect to these rats the one important thing is that gain weight was significant only in the group that received Pinaverium Bromide. Conclusion: In our study we demonstrated that both, Tegaserod and Pinaverium Bromide can be effective treating diarrhea and constipation in an experimental model in rats.
