Welax Solution contains Lactitol 10gm per 15ml and is indicated for the treatment of constipation. Lactitol is a synthetic disaccharide with osmotic laxative properties that acts by increasing the osmotic pressure in the colon, thereby drawing water into the bowel lumen. This results in softening of stools and stimulation of bowel movements, facilitating easier defecation. Welax Solution is particularly useful in cases of chronic constipation, opioid-induced constipation, and in patients where stool softening is desired. It is generally well tolerated, with minimal systemic absorption, reducing the risk of systemic side effects. The onset of action typically occurs within 24 to 48 hours following oral administration. Dosage should be individualized based on patient response and severity of constipation, with adjustments made to optimize efficacy while minimizing potential adverse effects such as bloating, flatulence, or abdominal discomfort. Caution is advised in patients with galactosemia or intestinal obstruction. Welax Solution should be used under medical supervision, especially in pediatric, elderly, or pregnant patients. Adequate hydration is recommended to enhance the laxative effect. This formulation provides a convenient oral liquid dosage form, facilitating ease of administration in patients with swallowing difficulties.
