Prophylaxis should be considered in children with frequent or severe periods. Prevention and treatment of CVS in children is very difficult and no specific and effective treatment has been proven in clinical trials. Propranolol is approved for the prophylaxis of CVS in children of all ages, but its effectiveness has been variable. In this study, we investigated the efficacy and safety of adding L-Carnitine to propranolol therapy in the prevention of pediatric CVS. Methods: 76 children who were diagnosed with CVS were included in this study. They were divided into two equal groups. The first group received high dose of Propranolol and the case group received L-Carnitine with low dose of propranolol for 6 months. Results: CVS attacks’ frequency in both groups of treatment with propranolol alone and in combination with L-Carnitine and propranolol, before and after the treatment was significantly reduced. But there is no significant difference between the two groups 70.6%) vs. 90.9%) (p-value=0.062). There was no significant reduction in the duration days between vomiting attack index in both groups (31.6 % vs.43.2%) (p-value= 0.345).Conclusion: Our research revealed that combination of low dosepropranolol with L-Carnitine has comparable efficacy with high dosePropranolol in prophylaxis of CVS.}, keywords = {children,Cyclic vomiting syndrome,L-carnitine,Propranolol}, url = {http://www.jimc.ir/article_159849.html}, eprint = {http://www.jimc.ir/article_159849_970d8bf5a02e8b6b3fc091115f20a940.pdf} }
