Meloxicam Cyclodextrin Composition for Faster Pain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Meloxicam, a nonsteroidal anti-inflammatory drug, has poor aqueous solubility, leading to reduced bioavailability and slow onset of pain relief.
Innovation Solution
Formulating meloxicam with sulfobutyl ether β-cyclodextrin (SBEβCD) and bicarbonate to create an inclusion complex, which increases solubility and bioavailability, and combining it with rizatriptan for rapid and sustained pain relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If meloxicam is used as a conventional NSAID formulation, then the drug provides anti-inflammatory and analgesic activities, but the poor aqueous solubility reduces bioavailability and slows the onset of pain relief
Solution Approach 1:
The patent uses cyclodextrins as intermediary carriers to solubilize meloxicam. The cyclodextrin molecules form inclusion complexes with meloxicam, where the hydrophobic interior of the cyclodextrin ring accommodates the meloxicam molecule while the hydrophilic exterior interacts with aqueous media, thereby enhancing solubility and bioavailability without altering the meloxicam molecule itself
Solution Approach 2:
The patent alters the physical-chemical parameters of meloxicam by forming inclusion complexes with cyclodextrins. This changes the solubility parameter of meloxicam from poor to enhanced, and accelerates the dissolution rate, thereby improving bioavailability and accelerating the onset of action while maintaining the pharmacological activity
2Reliability
If cyclodextrins are used to increase solubility of meloxicam, then bioavailability is enhanced, but the formulation complexity increases
Solution Approach 1:
The cyclodextrin-meloxicam inclusion complex forms spontaneously in aqueous solution without requiring complex formulation processes. The hydrophobic interaction between cyclodextrin and meloxicam drives the self-assembly of the inclusion complex, eliminating the need for sophisticated manufacturing equipment or multi-step processes while achieving enhanced solubility
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 combination provides rapid, sustained, and statistically significant pain relief, reducing the need for rescue medication and improving treatment outcomes in conditions like migraine and arthritis.
Implementation Method 1
In aqueous solutions, cyclodextrins can form complexes (i.e., an inclusion complex) with drugs by incorporating the drug into the center/hydrophobic portion of the cyclodextrin ring
Implementation Method 2
Cyclodextrins are hydrophobic on the inside and hydrophilic on the inside which helps to facilitate the transport of molecules

AI summary
Disclosed herein are compositions comprising an NSAID such as meloxicam and/or rizatriptan in combination with a cyclodextrin and/or a carbonate or a bicarbonate. These compositions may be orally administered, for example, to improve the bioavailability or pharmacokinetics of the NSAID for the treatment of pain such as migraine, arthritis, and other conditions. Also disclosed herein are methods of treating pain, such as migraine, comprising administering meloxicam and rizatriptan to a human being suffering from pain, such as migraine. For migraine, these methods may be particularly useful when the meloxicam and rizatriptan are administered while the human being is suffering from an acute attack of migraine pain or migraine aura. In some embodiments, the combination of meloxicam and rizatriptan may be administered in a manner that results in a Tmax of meloxicam of 3 hours or less.
