Lactihep Syrup contains Lactitol (66.67% w/v) as its active ingredient and is primarily indicated for the treatment of chronic constipation and hepatic encephalopathy. Lactitol is a synthetic disaccharide that acts as an osmotic laxative by increasing the osmotic pressure in the colon, thereby promoting bowel movements through enhanced water retention in the intestinal lumen. This mechanism facilitates softening of stools and eases defecation without causing significant electrolyte imbalance. Additionally, Lactitol is utilized in the management of hepatic encephalopathy by reducing the absorption of ammonia in the gut, thus lowering systemic ammonia levels and improving neurological symptoms associated with liver dysfunction. The syrup formulation allows for easy administration, particularly in pediatric and geriatric populations. Lactihep Syrup is generally well tolerated; however, mild gastrointestinal side effects such as bloating, flatulence, and abdominal discomfort may occur. It is contraindicated in patients with galactosemia or intestinal obstruction. Caution is advised in individuals with diabetes mellitus due to its sugar content. Dosage should be individualized based on clinical response and severity of the condition. Lactihep Syrup should be used under medical supervision to ensure safety and efficacy.
