Benefits of technology

"The patent text describes a pharmaceutical composition that includes a lipase inhibitor and a bile acid sequestrant. The composition can also contain other excipients such as fillers, surfactants, and colorants. The invention also provides a kit for treating obesity with a lipase inhibitor and a bile acid sequestrant. The use of a bile acid sequestrant can help reduce gastrointestinal side effects associated with lipase inhibitor treatment. The technical effect of the invention is to provide an improved method for treating obesity with a combination of a lipase inhibitor and a bile acid sequestrant."

Problems solved by technology

However, in a subgroup of the patients, unpleasant gastrointestinal side effects such as oily spotting, fatty / oily stools, fecal urgency, increased defecation and fecal incontinence are observed.

example 1

Study A

[0067] Xenical was ingested t.i.d. by two middle aged healthy male volunteers on a normal average mixed diet. Both individuals frequently experienced one or more of the above mentioned unpleasant gastrointestinal side effects. After 4 weeks on Xenical they started to ingest in addition to Xenical b.i.d. cholestyramine containing sachets (4 g / meal) which were emptied into about 100 ml water, swirled and drunk during the meals. The side effects were immediately reduced in frequency and completely disappeared. After 2-4 weeks of combined intake together with Xenical, cholestyramine was discontinued. When treatment with Xenical alone was carried on the gastrointestinal adverse events reappeared.

example 2

Study B

[0068] The anti-GI side effect potential of bile salt sequestrants was extended further in short-term studies in human volunteers. To precipitate the tendency for side effects in this model three meals (lunch, dinner, breakfast) are ingested together with Xenical and 120 mg orlistat in 10 g butter, each. The model is based on the idea that GI side effects following orlistat ingestion are precipitated by the formation of free oil. Free oil is oil, which will coalesce in the dietary fat emulsion passing down the GI tract and separate from the stool matrix. In this model the amount of oil which is separated from the stool matrix is determined after the production of stools.

[0069] It was demonstrated in human volunteers that after co-administration of cholestyramine and colestipol, respectively, the formation of free oil was dramatically reduced (cholestyramine: 44% of the respective control experiment without addition of cholestyramine) or nearly completely suppressed (colesti...

Abstract

A pharmaceutical combination or composition containing a lipase inhibitor, preferably orlistat, and a bile acid sequestrant is useful for treating obesity.

Description

[0001] This application is a continuation of U.S. patent application Ser. No. 11 / 062,086, filed Feb. 18, 2005, currently pending, and U.S. patent application Ser. No. 10 / 718,049, filed Nov. 20, 2003, currently pending, which is a divisional of U.S. patent application Ser. No. 09 / 912,957, filed Jul. 25, 2001, now U.S. Pat. No. 6,756,364, issued Jun. 29, 2004. The entire contents of the above-identified applications are hereby incorporated by referenceBACKGROUND OF THE INVENTION [0002] 1. Field [0003] The present invention relates to pharmaceutical combinations, compositions and methods for treating obesity. [0004] 2. Description [0005] Bile acids are synthesized in the liver and enter the bile as glycine and taurine conjugates. They are released in salt form in bile during digestion and act as detergents to solubilize and consequently aid in digestion of dietary fats. Following digestion, bile acid salts are mostly reabsorbed in the ileum, complexed with proteins, and returned to the...
