Preferred lipase inhibor is selected from orlistat, cetilistat, saponins, cioscin, escins, cyclocanosides, polyphenols, terpenes, and pancreatic lipase inhibitors. The lipase inhibitor can be administered topically, ΓΜ , Γ , SC, or mucosally. THERAPY FOR CONSTIPATION FIELD OF THE INVENTION [001] The present invention relates to methods and compositions for the treatment of bowel disorders, especially constipation associated with the administration of painkillers. BACKGROUND OF THE INVENTION [002] Constipation is a frequent side effect of many conditions and medications. For example, opioids may lead to constipation since these agents decrease peristaltic activity in the gastrointestinal (Gl) tract. Because of the mechanisms involved in opioid- induced constipation, some treatments that may be applicable for common, functional constipation are inappropriate for ambulatory-care patients prescribed opioid analgesics. Also in these patients, the distress of constipation may add to the discomfort already present from pain, and they might decrease or discontinue the opioid to avoid constipation. Therefore motivating such patients to comply with their opioid therapy also requires an approach for managing constipation [003] Constipation is broadly defined as the passage of hard, dry stools less frequently than the patient's usual bowel-habit pattern. [004] Constipation resulting from opioid use is the most common component of a more general condition called opioid-induced bowel dysfunction, OBD. Signs and symptoms of OBD include dry hard stools, straining during evacuation, incomplete evacuation, bloating, abdominal distension, and retention of the contents of the bowel. [005] Bulk-forming laxatives are typically not appropriate in opioid-induced constipation because peristalsis is inhibited in these patients so stool softener and bowel stimulants are often used. Some patients may take mild over-the-counter bulk laxatives and fail to mention this to their physician. This can result in painful, colic-like symptoms. [006] Attempts have been made to solve the problem of opioid induced constipation. For example, U.S. patent no. 6982283 discloses a method for treating drug-induced constipation that comprises administering an effective amount of 15-keto-prostaglaindin compound to a subject suffering from drug-induced constipation or a subject having a strong possibility of suffering from it. U.S. patent no. 8278323 describes certain quinolizidine and octahydropyridopyrazine compounds, pharmaceutical compositions, and methods of their use as opioid receptor antagonists for the treatment of opioid induced constipation. The use of an opioid antagonist effectively reduces the amount of physiologically available opioid. However, the dose that leads to constipation is approximately four-fold less than the dose required for an analgesic response. SUMMARY OF THE INVENTION [007] In one aspect of the invention, there is provided a method of treating acute, sub acute or chronic constipation in a patient having a condition requiring such treatment, comprising the administration of a lipase inhibitor. [008] J n one preferred embodiment the lipase inhibitor is selected from the group consisting of: orlistat, atl-962 (cetalstat) and gt389-255. [009] In another preferred embodiment, the lipase is naturally and comprise saponins, platycodin saponins, scabio saponins, sessiloside and chiisanoside, chikusetsusaponins, dioscin and derivatives, escins, teasaponins, cyclocariosides, polyphenoics, oolong tea polyphenols, polyphenol rich extracts including grape seed extract, nelumbo nucifera extract, salacia reticulata hot water extract, peanut shell extract, mangifera indica leaf and steam bark extracts, ct-ii extracts, terpenes including carnosic acid, crocin and crocetin and pancreatic lipase inhibitors from microbial sources such as lipstatin. [0010] In another embodiment the condition is selected from the group consisting of opiod administration, dehydration, lazy bowel, paralytic bowel, menstruation related constipation, bowel resection and being bedridden. [001 1] In a further embodiment the lipase inhibtor is administered topicalll, IM, IV, SC, or mucosally. [0012] In yet another embodiment the preferred lipase inhibitor is orlistat or cetalstat [0013] In another aspect the invention is a method for treating chronic pain comprising administering a pain medication in combination with a lipase inhibitor. [0014] In another aspect of the invention there is provided a composition for the treatment of chronic constipation comprising 30 to 150 mg of a lipase inhibitor. [0015] In a preferred embodiment the composition is formulated for oral administration. [0016] In another embodiment the composition is in the form of a tablet, lozenge, pill, troche, capsule, soft-gel capsule, sachet or other combining vehicle, elixir, powder, including lyophilised powder, solution, granule, suspension, emulsion, syrup or tincture. Slow-release, or delayed-release, forms may also be prepared, for example in the form of coated particles, multi-layer tablets or microgranules.. [0017] In another embodiment the composition is provided in a compliance-enhancing blister pack DETAILED DESCRIPION [0018] The present invention provides a novel method of treatment for constipation. This novel type of treatment has a much improved therapeutic result for those who are suffering chronic constipation related to the use of opiates, other pain-killers, antidepressants and other situations such as paralysis, infection, cancer, radiation therapy and dehydration. [0019] Lipase inhibitors are typically used for aiding weight loss. The active ingredient in some of the prescription products such as Xenical and Alii is orlistat. Other lipase inhibitors that function in the same way are herbal or are naturally sourced. [0020] Lipase inhibitors block the action of the two compounds found in the digestive juices of the stomach and small intestine. These enzymes are known to break down the fat molecules that are in our diet. Without the action of these compounds, the molecules of fat are too large to be digested by our stomach and then to enter our bloodstream. Lipase inhibitors essentially keep the fat molecule intact and undigested thus instead of becoming part of the body, the fat is excreted as waste through the bowels. [0021] One of the known side effects of lipase inhibitors like Xenical is that the patient may experience loose bowels including episodes of diarrhea. This is of course a negative side effect for those persons who are taking the medication for weight-loss. [0022] For those persons facing a problem of chronic constipation, the use of lipase inhibitors offers a new treatment alternative. The lipase inhibitors that block the production of pancreatic and gastric enzymes that break down fat provided to treat chronic constipation is a novel use for these compounds. [0023] The present invention provides a novel approach to the provision of such antigens and immunogens by inactivation of purified RS virus. [0024] According to the present invention synthetic, chemical or naturally

In acute pancreatitis, a prebiotic enriched diet is associated with low rates of pancreatic necrosis infection, hospital stay, systemic inflammatory response syndrome and multiorgan failure. This protective effect seems to be connected with the ability of fibre to stabilise the disturbed intestinal barrier homeostasis and to reduce the infection rate. On the other hand, in patients with exocrine pancreatic insufficiency, a high content fibre diet is associated with an increased wet fecal weight and fecal fat excretion because of the fibre inhibition of pancreatic enzymes. The mechanism by which dietary fibre reduces the pancreatic enzyme activity is still not clear.

  • Kojic Acid Repurposing As a Pancreatic Lipase Inhibitor and the Optimization of Its Production from a Local Aspergillus Oryzae S
    El-Korany et al. BMC Biotechnology (2020) 20:52 https://doi.org/10.1186/s12896-020-00644-9 RESEARCH ARTICLE Open Access Kojic acid repurposing as a pancreatic lipase inhibitor and the optimization of its production from a local Aspergillus oryzae soil isolate Sarah Mohamed El-Korany1, Omneya Mohamed Helmy1*, Ali Mahmoud El-Halawany2, Yasser El-Mohammadi Ragab1 and Hamdallah Hafez Zedan1 Abstract Background: Obesity and its related diseases are increasing worldwide. One of the best therapeutic strategies for obesity management is through the inhibition of pancreatic lipase (PL) enzyme. So far orlistat is the only FDA approved PL inhibitor, but with unpleasant side effects. New efficacious anti-obesity drugs are needed to achieve a successful reduction in the incidence and prevalence of obesity. Many microbial metabolites have PL inhibitory activity. Screening soil inhabitants for PL inhibitors could help in increasing the available anti-obesity drugs. We aimed to isolate and identify alternative PL inhibitors from soil flora. Results: We screened the crude mycelial methanolic extracts of 39 soil samples for PL inhibitory activity by the quantitative lipase colorimetric assay, using the substrate p-nitrophenyl palmitate and orlistat as positive control. AspsarO, a PL inhibitor producer, was isolated from an agricultural field soil in Giza, Egypt. It was identified as Aspergillus oryzae using colony morphology, microscopical characteristics, 18S rDNA sequencing, and molecular phylogeny. Increasing the PL inhibitor activity, in AspsarO cultures, from 25.9 ± 2% to 61.4 ± 1.8% was achieved by optimizing the fermentation process using a Placket–Burman design. The dried 100% methanolic fraction of the AspsarO culture had an IC50 of 7.48 μg/ml compared to 3.72 μg/ml for orlistat.

KEYWORDS: Obesity, lipase inhibitor, anti-lipase activity, Quercus infectoria, nutgall INTRODUCTION Obesity is the most common metabolic disease in developed nations. There are various therapeutic approaches to treating obesity, including suppression of food intake, increased thermogenesis, accelerated lipolysis and inhibition of lipogenesis. It has been suggested that inhibition of digestion and absorption of dietary fat is a key factor in treating of obesity so the application of a pancreatic lipase inhibitor was widely interesting. The only pancreatic lipase inhibitor currently appoved for longterm treatment of obesity is Orlistat. The use of Orlistat frequently results in adverse events including flatus, oily stools, fecal urgency or fecal incontinence, and abdominal pain (Harold E. Bays, 2004). Therefore, there is a need for more lipase inhibitors or medicinal products that are safe and effective. Previously we screened the anti-lipase activity of fifteen Thai herbs belonging to different families such as Compositae, Lauraceae, Labiatae, Rutaceae and Zingiberaceae. Qurercus infectoria (Fagaceae) is a small tree or a shrub mainly present in western Asia and Southern Europe. The galls of Q. infectoria have been known to possess medicinal properties, such as astringent, anti-inflammatory, antiviral, antidiabetic, larvicidal, antibacterial, antiulcerogenic and gastroprotective activities The main constituents found in the galls of Q. infectoria are tannin (50-70%) and small amount of free defined as water–soluble polyphenolic compounds that have theability to precipitate proteins (Umachigia SP, et al., 2008).

J Food Nutr 7: 1-12 Abstract Lipids play important biological functions such as maintenance of the cell integrity, storage for energy metabolism and as signaling molecules. Changes in lipid metabolic pathways can either lead to therapeutic benefits or cause illness. Anti-obesity drugs for example down regulate the digestion of dietary triglycerides minimizing their uptake and thereby treat chronic obesity. Pancreatic lipase plays a central role in this process and therefore represents the preferred target for anti-obesity drugs. In the past years, a broad range of natural and synthetic pancreatic lipase inhibitors have been described. In this contribution, we aim at giving a structured overview over the diversity of these drugs, illuminate their mode of action and critically discuss their undesired side effects. We recommended that further investigations are warranted to ascertain the efficacy, safety and pharmacological potential of herbal medicines. Medicinal herbs must be tested for bioactivity and toxicity to make marketed formulation and standardization.

Quercetin was the strongest inhibitor (IC50=(6.1±2.4) µM), followed by p-coumaric acid ((170.2±20.6) µM) and caffeic acid ((401.5±32.1) µM), while capsaicin and a hot pepper extract had very low inhibitory activity. All polyphenolic compounds showed a mixed-type inhibition. Fluorescence spectroscopy studies showed that polyphenolic compounds had the ability to quench the intrinsic fluorescence of pancreatic lipase by a static mechanism. The sequence of Stern-Volmer constant was querce- tin, followed by caffeic and p-coumaric acids. Molecular docking studies showed that caffeic acid, quercetin and p-coumaric acid bound near the active site, while capsaicin bound far away from the active site.

Obesity is recognized as a major life style disorder especially in developing countries and it is prevailing at an alarming speed in new world countries due to fast food intake, industrialization, and reduction of physical activity. Furthermore, it is associated with a vast number of chronic diseases and disabilities. To date, relatively effective drugs, from either natural or synthetic sources, are generally associated with serious side effects, often leading to cessation of clinical trials or even withdrawal from the market. Inorder to find new compounds which are more effective or with less adverse effects compared to orlistat, the drug that has been approved for obesity, new compounds isolated from natural products are being identified and screened for antiobesity effects, in particular, for their pancreatic lipase inhibitory effect.

Many secondary metabolites isolated from natural products have shown therapeutic action against these enzymes. However, some commercially available synthetic drugs have shown unfriendly impacts with various side effects. Thus, this research has focused on a comprehensive study of secondary metabolites showing better inhibitory activities towards metabolic enzymes such as α-amylase, α-glucosidase, aldose reductase, and lipase. Further receptor-based virtual screening was performed against the various secondary metabolites database designed in-silico. Using Gold combined with subsequent post-docking analyses, the score was obtained
