Lactitol Monhydrate and Ispaghula Husk Granules

This combination is provided by combining a bulkforming laxative in the form of psyllium husk (Ispaghula husk) with an osmotic laxative such as lactitol for Idiopathic constipation and is used to prevent or treat constipation. Constipation is a common problem which can be caused by a number of things. Not eating enough fiber or not drinking enough fluid can cause constipation. Some conditions can cause constipation such as such as pregnancy or lack of exercise or movement (such as being ill in bed) or some medicines. It is a common problem for adults and pediatric patients and can generate considerable suffering for patients due to both the unpleasant physical symptoms and psychological preoccupations that can arise. In this combination, Lactitol is an osmotic disaccharide laxative that increases fecal volume and stimulates peristalsis. Ispaghula husk helps relieve constipation and as a laxative, works by increasing the bulk of stools, which encourages bowels to move the stools through digestive system, which in turn relieves constipation. Bulkforming laxatives absorb water and expand in the colonic lumen; in contrast, osmotic laxatives retain water in the colonic lumen by osmosis. So, both laxatives act to retain water in the colonic lumen thereby counteracting the normal dehydrating action of the colon. By suppressing the dehydration action of the colon, the osmotic laxative produces a fecal stream which is softer, bulkier and easier to expel. These laxatives also help to produce formed stools, without any systemic toxicity.

LACTITOL MONOHYDRATE

Lactitol is an osmotic disaccharide laxative that increases fecal volume and stimulates peristalsis and analogue of lactulose. Osmotic laxatives are widely prescribed in the management of constipation due to their superior efficacy, tolerability and safety in pediatric patients, during pregnancy and elderly population. With its more pleasant taste, it is better tolerated and more palatable. It is used in the management of hepatin encephalopathy and in constipation. The efficacy and tolerance of lactitol and lactulose are similar, with a trend for more frequent stools with lactitol. Lactitol has calorific value of 2 kcal/g (8.5 KJ/g) and has no effect on blood glucose levels. It can, therefore, be given to diabetes patients. Lactitol is a disaccharide derivative consisting of galactose and sorbitol, which is only minimally absorbed and is not, hydrolysed by the disaccharidases of the gastrointestinal tract and, thus, reaches the colon unchanged. In the colon, it is broken down into shortchain organic acids, mainly acetic, propionic and butyric acid, by the intestinal flora, in particular by the bacteroides and lactobacilli, thus acidifying the contents of the colon. The effect of this acidification reduces the absorption of ammonia. The transformation of lactitol into lowmolecular weight organic acid results in an increase in osmotic pressure in the colon, thereby causing an increase in the stool water content and stool volume, which explains the laxative affect. The mechanism of action of lactitol in hepatic encephalopathy is most likely related to suppression of the absorption of unionized ammonia via lowering of colonic pH; a cathartic action also enhances faecal nitrogen excretion and decreases intestinal transit time, with a reduction in the time for production and absorption and other potential toxins.

PHARMACOKINETIC OF LACTITOL

ABSORPTION:
Lactitol is not significantly absorbed in the small intestine; only 0.5% to 2% of a dose is partially absorbed as unchanged lactitol
METABOLISM:
Absorbed volatile fatty acids are metabolized in the colon
EXCRETION:
6.5% excreted in the feces. Small amounts of unchanged lactitol appear in the urine (2% or less of a dose)

ISPAGHULA

Botanically, Isabgol (also called Psyllium & Ispaghula) is Plantago ovata. Sat Ispagol (also called Psyllium Husk & Isaghula Husk) is husk outer membranous covering of the Plantago ovata seeds, which is useful in relieving constipation and has other therapeutic benefits and uses. Ispaghula husk has gentle laxative action that depends on the fiber content, so it is not actually true purgative. It can be categorized under bulk forming laxatives. The flour of Isab gol Husk is added in multigrain flour to enhance nutritive value as well as fiber content of cereal flours. It can absorb 14 times more water than its weight. Therefore, the high amount of liquids or water should be consumed while taking Ispaghula husk. It will also help preventing immediate side effects like choking.
INDICATIONS FOR ISPAGHULA HUSK:
CONSTIPATION:
The first line of treatment of constipation is dietary changes including high fiber diet and fruits & vegetables. Ispaghula is very rich in fiber and it absorbs water from the intestine and produces more bulk, which stimulates intestinal contractions and peristaltic movements. Due to this, the passage of stools becomes easier and thus it removes constipation.
DIARRHEA & DYSENTERY:
Ispaghula Husk absorbs water content from digestive tract and produce bulk, which makes stool firmer. Secondly, it also clears the intestines, which helps removing infection – causing microbes from the alimentary canal and speeds up the recovery process. Psyllium alone is effective treatment for mild to moderate diarrhea, but it may be used as adjuvant therapy in severe diarrhea and dysentery. Acidity & Heartburn: Ispagol is a good remedy for acidity and heart burn. When it passed through the food pipe and stomach, it lubricates the membranous walls, which reduces irritation due to the excess acid. It also flushes out the excess acid from the stomach to the intestine by absorbing the acid. Thus, due to these mechanisms, it helps reducing the symptoms of hyperacidity and heartburn. Others are: Excessive Hunger (Polyphagia); Excessive Thirst (Polydipsia); Skin: Dysesthesia: Burning skin sensation (external application); other skin diseases with main symptom of burning sensation.
