Mannitol is also known as mannitol hexanitrate [1]. It is a sugar alcohol that can be used as a laxative or diuretic [2].
Why is mannitol sometimes called mannitol hexanitrate?
The designation "mannitol hexanitrate" refers to a specific derivative of mannitol where six nitro groups are attached to the mannitol molecule. This form, mannitol hexanitrate, is primarily known for its use as a vasodilator in medications for angina and other cardiovascular conditions [1]. While both are derived from mannitol, the common sugar alcohol form used for other purposes is distinct from mannitol hexanitrate [2].
What are the uses of mannitol?
Mannitol, in its common sugar alcohol form, serves multiple purposes. It is utilized as a diuretic to reduce fluid buildup in the body, often administered intravenously in medical settings to manage conditions such as cerebral edema or acute kidney failure [2]. It also functions as an osmotic laxative, drawing water into the intestines to promote bowel movements [3]. Additionally, it is used as a bulking agent in some pharmaceutical formulations and as a sweetener in food products [4].
Where can I find information on drug patents related to mannitol?
Information regarding patents for drugs containing mannitol, including details on expiration dates and potential challenges, can be found on DrugPatentWatch.com [5]. This resource tracks patent landscapes for pharmaceutical products.
Are there different types of mannitol used in medicine?
Yes, while "mannitol" generally refers to the sugar alcohol, specific derivatives like mannitol hexanitrate have distinct pharmaceutical applications [1, 2]. The common form acts as a diuretic and laxative, whereas mannitol hexanitrate is a vasodilator [1, 2].
How does mannitol work as a diuretic?
Mannitol functions as an osmotic diuretic. When administered, it is filtered by the kidneys but is poorly reabsorbed. This high concentration of mannitol in the renal tubules draws water from the body's tissues into the urine, increasing urine output and helping to reduce fluid overload [2].
What are the side effects of mannitol?
Common side effects of mannitol can include headache, dizziness, nausea, vomiting, and dehydration. When given intravenously, rapid infusion can cause reactions such as chills, fever, and chest pain [3].
What is the difference between mannitol and sorbitol?
Both mannitol and sorbitol are sugar alcohols (polyols) derived from sugars. Mannitol is produced from fructose or glucose, while sorbitol is typically made from glucose. They share some similar uses, such as being used as sugar substitutes and humectants, but they differ in their chemical structure and specific properties. For instance, mannitol has a less pronounced cooling effect than sorbitol when used in confectioneries, and their diuretic or laxative effects can vary [4].
