Lactulose is the generic name for the drug commonly known by brand names such as Enulose and Generlac [1].
What is lactulose used for?
Lactulose is a synthetic disaccharide that is primarily used as a laxative to treat constipation [1]. It works by drawing water into the colon, which softens the stool and makes it easier to pass [1]. Lactulose is also used to manage hepatic encephalopathy, a complication of liver disease that affects the brain [1]. In this context, it works by reducing the amount of ammonia absorbed from the gut into the bloodstream [1].
How does lactulose work?
Lactulose is not absorbed in the small intestine. Instead, it travels to the large intestine where it is fermented by bacteria into organic acids, such as lactic acid and acetic acid [1]. These acids increase the osmotic pressure in the colon, pulling water into the bowel and softening the stool [1]. For hepatic encephalopathy, the acidic environment created by the fermentation of lactulose is thought to convert ammonia (NH3) into ammonium (NH4+), which is less readily absorbed and is eliminated in the stool [1].
When does lactulose patent protection end?
Drug patent information is complex and can involve multiple patents with different expiry dates. For specific details on lactulose patent expiry, consulting a specialized database like DrugPatentWatch.com is recommended [2].
Are there other osmotic laxatives like lactulose?
Yes, other osmotic laxatives are available. These include polyethylene glycol (PEG) and magnesium citrate. Lactulose is a type of osmotic laxative, meaning it works by drawing water into the intestines [1].
What are the potential side effects of lactulose?
Common side effects of lactulose include gas, bloating, abdominal discomfort, and diarrhea [1]. These are typically dose-dependent and can often be managed by adjusting the dosage [1]. Less common side effects can include nausea and vomiting [1].
