The study is aimed at the efficacy and safety evalutation of the study treatments through a 2-weeks study period and the subsequent follow-up-
This multicenter, prospective, randomized, controlled trial will be conducted on 120 infants-children with a diagnosis of chronic functional constipation according to the definition of Criteria of Rome III. The enrolled subjects will be randomized according to an electronically generated randomization list in 2 groups: one group will receive micro-enemas of Promelaxin® (Group A) while the second group will receive Macrogol 4000 per os (Group B) . Children will receive the dedicated treatment for two weeks and then undergo a follow-up period of a maximun of 6 weeks. The hypothesis is that the protective micro-enema will help achieving regular evacuation by its local antinflammatory non-pharmacological action. This hypothesis is based on the finding that local anal inflammation can cause functional constipation due to discomfort and pain during evacuation or by influencing reflexes.
