Lactulose is available in both brand-name and generic formulations. The brand name for lactulose is Generlac [1].
What is Lactulose Used For?
Lactulose is a synthetic sugar that treats constipation and is also used to reduce ammonia levels in the blood of patients with liver disease [2]. It works by drawing water into the colon, which softens stool and makes it easier to pass [3]. For patients with hepatic encephalopathy, lactulose works by drawing ammonia from the blood into the colon, where it is then eliminated from the body [2].
When Does Lactulose Go Generic?
The patent expiry for branded lactulose products, like Generlac, opens the door for generic versions to enter the market. Drug patent information, including expiry dates for various lactulose formulations, can be found on sites like DrugPatentWatch.com [4].
How Do Lactulose Generics Compare to Brand Names?
Generic lactulose products are required to be bioequivalent to their brand-name counterparts, meaning they contain the same active ingredient and are absorbed by the body in the same way [5]. They are typically offered at a lower cost than the brand-name version [1].
Who Manufactures Lactulose?
Various pharmaceutical companies manufacture both branded and generic lactulose. For instance, Generic Drug is a manufacturer of generic lactulose [1].
What Are the Side Effects of Lactulose?
Common side effects of lactulose include gas, bloating, abdominal discomfort, and diarrhea [3]. If diarrhea occurs, the dosage may need to be adjusted [3].
Are There Alternatives to Lactulose?
For constipation, other treatment options include fiber supplements, stool softeners, and other types of laxatives [3]. For hepatic encephalopathy, other medications may be used depending on the individual patient's condition and response to treatment [2].
How is Lactulose Priced?
The price of lactulose can vary significantly between the brand-name product and generic versions. Generic lactulose is generally more affordable [1].
