Free Fatty Acids for Rectal Laxative Stimulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laxatives often cause side effects and discomfort, and there is a need for effective, side-effect-free alternatives to treat constipation and related bowel issues.
Innovation Solution
The use of free fatty acids and fatty acid mixtures, particularly those derived from natural oils, to stimulate defecation by activating polymodal nociceptors in the rectal mucosa, formulated into suppositories, enemas, or other dosage forms to induce bowel movements with minimal discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional laxatives are used to treat constipation, then bowel movement is stimulated, but side effects such as abdominal discomfort, faintness and cramps occur
Solution Approach 1:
The patent changes the chemical parameter of the laxative agent from conventional substances (senna, bisacodyl, castor oil) to free fatty acids with specific chain lengths (C6-C24). This parameter change maintains the laxative effect while eliminating the harmful side effects associated with conventional laxatives, as fatty acids naturally stimulate bowel movements without causing abdominal discomfort or cramps.
Solution Approach 2:
The patent employs simple, naturally occurring free fatty acids that are metabolized and eliminated quickly from the body after performing their laxative function. These short-acting fatty acid molecules provide effective bowel stimulation but do not accumulate or cause long-term side effects, unlike some conventional laxatives that may cause dependence or persistent gastrointestinal issues.
2Reliability
If castor oil is administered orally for laxative effect, then bowel movement is induced, but bioavailability of drugs and nutrients is reduced
Solution Approach 1:
The patent extracts and isolates the active laxative component (free fatty acids) from complex natural oils like castor oil. By using purified free fatty acids instead of whole castor oil, the invention maintains the bowel-stimulating effect while eliminating the triglyceride structure that causes interference with drug and nutrient absorption. The free fatty acids act locally in the intestine without the same bioavailability issues as oral oil administration.
3Reliability
If fat base suppositories are used for rectal administration, then laxative effect is achieved, but irritation is induced by the fat base
Solution Approach 1:
The patent changes the chemical composition parameter of the suppository base from conventional fats and oils to free fatty acids. This parameter change eliminates the irritation problem associated with fat bases while maintaining the laxative effect, as free fatty acids are naturally compatible with rectal mucosa and do not cause the inflammatory response that occurs with traditional fat-based suppositories.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The fatty acid compositions effectively stimulate bowel movements with reduced side effects, as demonstrated in clinical examples, providing a stable and effective treatment for constipation and related conditions like hemorrhoids and pruritus ani.
Implementation Method 1
free fatty acids and fatty acid mixtures act as chemical bowel stimulant on the polymodal nociceptors in the rectal mucosa initiating the process of defecation
Data Source
AI summary
The invention relates to fatty acid stimulation of rectal mucosa initiating the process of defecation, acting as a laxative. Furthermore, the invention relates to the usage of free fatty acids, fatty acid mixtures and fatty acid extracts from marine lipids in pharmaceutical formulations such as suppositories, ointments, tablets and gelatin capsules for treatment and prevention of multiple disorders like constipation, hemorrhoids, bacterial infections (e.g. helicobacter pylori), viral infections (e.g. herpes simplex virus infections) and inflammations, as well as against fissura ani and pruritus ani.
