Lactulose

Introduction: What is Lactulose?

Lactulose is a synthetic sugar used primarily as a laxative and to treat hepatic encephalopathy, a condition that affects the brain due to liver dysfunction. It is a nonabsorbable disaccharide that helps to soften stools and promote bowel movements. Lactulose is often prescribed for patients who experience constipation or need to reduce ammonia levels in the blood, making it a vital medication in managing certain gastrointestinal and liver-related conditions.

Uses of Lactulose

Lactulose has several approved medical uses, including:

• Sembelit: It is commonly used to treat chronic constipation by increasing the water content in the stool, making it easier to pass.
• Ensefalopati Hepatik: Lactulose helps reduce the absorption of ammonia in the intestines, which can improve mental function in patients with liver disease.
• Penyediaan usus: It may be used to prepare the bowel for certain medical procedures, such as colonoscopy.

Langkah-langkah untuk Copytrade

Lactulose works by drawing water into the colon, which softens the stool and increases its volume. This process stimulates bowel movements. In the case of hepatic encephalopathy, lactulose is fermented by bacteria in the colon, producing acids that lower the pH of the gut. This acidic environment helps convert ammonia into ammonium, which is less readily absorbed into the bloodstream, thereby reducing ammonia levels in the body.

Dos dan Pentadbiran

Dewasa:

The typical starting dose for constipation is 15-30 mL (or 10-20 grams) taken once daily. For hepatic encephalopathy, the dose may start at 30-45 mL (or 20-30 grams) taken 3-4 times daily, adjusted based on the patient's response.
