Lactiol Syrup, containing Lactitol at a concentration of 66.67% w/v, is an osmotic laxative indicated for the treatment of constipation and related gastrointestinal conditions. Lactitol is a synthetic disaccharide that is poorly absorbed in the small intestine, reaching the colon where it undergoes fermentation by colonic bacteria, resulting in increased osmotic pressure and stimulation of bowel motility. This mechanism facilitates softening of stools and promotes regular bowel movements, making it effective in managing chronic constipation, opioid-induced constipation, and preparation for bowel procedures. Lactiol Syrup is generally well tolerated, with minimal systemic absorption and a low risk of systemic side effects. Common adverse effects may include mild abdominal discomfort, bloating, flatulence, or diarrhea, typically resolving with dose adjustment. It is contraindicated in patients with known hypersensitivity to lactitol or other components, intestinal obstruction, or acute inflammatory bowel diseases. Caution is advised in patients with diabetes mellitus due to the sugar content. Lactiol Syrup should be administered orally, with dosage tailored to individual response, and under medical supervision when used in pediatric or elderly populations. Adequate hydration is recommended during treatment to enhance efficacy and reduce adverse effects.
