Abstract
Description
The present invention relates to a pharmaceutical composition comprising felubipropene and one or more proton pump inhibitors (PPI) for the prevention and treatment of gastrointestinal disorders associated with felubiprofen, a propionic acid nonsteroidal antiinflammatory drug (NSAID) .
Pelubiprofen, a propionic acid nonsteroidal antiinflammatory drug (NSAID), is a COX-2 inhibitor, a type of cyclooxygenase, used in the treatment of osteoarthritis, rheumatoid arthritis and back pain. NSAIDs, including felubipropene, are one of the most commonly used drugs in the world, but their use frequently involves gastrointestinal side effects such as peptic ulcer and indigestion.
Most of these gastrointestinal side effects, which occur in 20-40% of NSAID users, occur in the stomach and small intestine, and can be caused by symptoms such as dyspepsia, erosion, gastritis, duodenitis and ulcers, and anemia due to excessive bleeding In extreme cases, it can pose a threat to life.
Various studies have been conducted to solve the gastrointestinal side effects of such NSAIDs. In Korean Patent Laid-Open No. 167078, there has been proposed a method in which a solution containing ibuprofen, which contains a plurality of drug particles dispersed in a hydrophilic, water- Sexual oral formulations are disclosed.
However, if it is designed as a delayed drug formulation, it may provide convenience to patients in terms of adherence to medication and may reduce gastrointestinal side effects, but the frequency and time for exposure of the drug to the gastrointestinal tract is still maintained, There is a need for measures to address gastrointestinal side effects.
Other methods for solving gastrointestinal side effects of NSAIDs include Esomeprazole, Dexlansoprazole, Lansoprazole, Omeprazole, Pantoprazole, Rabeprazole, An anti-ulcer agent such as a proton pump inhibitor (PPI) such as Ilaprazole, Tenatoprzole, Leminoprazole and Nepaprazole can be administered simultaneously or in advance with the NSAID, Gastrointestinal side effects There have been studies to improve the symptoms of high-risk patients.
However, some anti-ulcer drugs, such as PPI, are prone to degradation and transformation in acid-reactive and neutral media. Accordingly, in Korean Patent Laid-Open Publication No. 2013-115593, an alkalizing agent is added to a layer containing PPI in a two-layer tablet containing NSAID and PPI to improve the stability of PPI, A preparation for creating an environment of a condition is disclosed.
However, the felubipropene used as an NSAID in the present invention is a poorly soluble drug in a low pH range, and thus bioavailability of the gastrointestinal tract needs to be improved for rapid pharmacological action in the gastrointestinal tract. As means for improving the dissolution rate of general oral preparations, there is a method of improving the dissolution rate of the oral preparation, such as addition of a surfactant, a method using a solid dispersion, a method of reducing the particle size such as nano- In the method of controlling the particle size of the active ingredient, the smaller the particle size, the greater the reactivity with other excipients contained in the formulation. In addition, the surfactant needs to be verified in many aspects in terms of the compatibility with the main component, and there is a problem in that the manufacturing cost is increased because the production of the solid dispersion becomes complicated.
The present inventors have found that the dissolution rate of felubipropene, which shows poor solubility at pH 1.2, which is an acidic condition, is greatly improved by the alkalizing agent during the evaluation of the preparation of the examples through the present invention. That is, the alkalizing agent added for the stability of PPI greatly improved the solubility of felubipropene, which was poorly soluble under acidic conditions.
Accordingly, the present invention aims to provide an agent which not only improves the stability of PPI by adding an alkalizing agent to a basic environment, but also can increase the bioavailability by improving gastrointestinal dissolution rate of felubiprofen The purpose.
The present invention provides a pharmaceutical composition comprising a non-steroidal anti-inflammatory drug (NSAID), felubiprofen, a proton pump inhibitor (PPI), and an alkalizing agent as a stabilizing agent.
The PPI of the present invention can be used in combination with other therapeutic agents such as Esomeprazole, Dexlansoprazole, Lansoprazole, Omeprazole, Pantoprazole, Rabeprazole, Ilaprazole, A pharmaceutically acceptable salt thereof, Tenatoprzole, Leminoprazole, Nepaprazole, a pharmaceutically acceptable salt thereof, a precursor and a mixture thereof.
The alkalizing agent of the present invention may be selected from the group consisting of calcium hydroxide, ethanolamine, potassium hydrogen carbonate, potassium citrate, sodium hydrogen carbonate, sodium hydroxide citrate, sodium hydroxide, calcium silicate, arginine, magnesium oxide, calcium carbonate, Sodium dihydrogen phosphate, magnesium carbonate, magnesium hydroxide, magnesium silicate, magnesium aluminum hydroxide, sodium borate, and meglumine.
According to an embodiment of the present invention, the alkalizing agent may be prepared in an amount of 2 to 20 parts by weight based on 1 part by weight of PPI.
The pharmaceutical composition of the present invention may be prepared by mixing the felubiprofen, the PPI, the alkalizing agent, the excipient, and the binder, combining them using an appropriate solvent, drying and sizing them to prepare tablet granules or granules for filling, And then adding a pharmaceutically acceptable excipient such as a lubricant to the granulated product.
In addition, the pharmaceutical composition of the present invention can be prepared in various forms of formulation, and in one embodiment, the present invention can be prepared in a single schedule containing felubiprofen, PPI and alkalizing agent in one layer .
In one embodiment, the invention can be made with tablets containing compartments containing the non-steroidal anti-inflammatory drug pelubiprofen and a compartment containing a proton pump inhibitor and an alkalizing agent as an additive. Where each compartment may be separated by known formulation techniques.
In one embodiment, the present invention can be prepared with a two-layer tablet consisting of a first layer containing felubiprofen and optionally an alkalizing agent and a second layer containing a PPI and an alkalizing agent. The first layer may or may not contain an alkalizing agent. By making the alkalizing agent exist in the same layer as the PPI, the storage stability of the PPI can be improved. At the same time, even if the felubipropene and the alkalizing agent are present in the same layer or are not present in the same layer, The microenvironment can be provided to increase the bioavailability by improving the dissolution rate of felubiprofen.
In one embodiment, the present invention can be prepared with capsules containing felubiprofen, PPI and an alkalizing agent.

Experimental Example 1. Determination of dissolution rate of an oral preparation containing felubiprofen
The following test was carried out to determine the dissolution rate of the felubipropene formulations according to the difference in additives such as alkalizing agents.
The dissolution rate test was carried out according to the dissolution test method 2 (paddle method) in the Korean Pharmacopoeia general test method. After 15 minutes from the start of the experiment, the eluate was taken out, filtered through a 0.45 mu m filter, and analyzed by UV.
As shown in Table 1, when a specific additive such as an alkalizing agent was used under pH 1.2 conditions exhibiting low solubility, felubiprofen showed a high dissolution rate of 70% or more. Therefore, the change of the pH in the body occurs by the specific formulation and the effect of increasing the solubility of felubiprofen was confirmed. There is room for rapid dissolution during the above residence time and an increase in bioavailability.

Specifically, each of the above-mentioned formulations was packed with 1 g of silica gel in an HDPE bottle and stored at 50 ° C and 85% RH. After 3 months under the above conditions was measured for representative degradation products of the content of flexible material C of the S-omeprazole Mg2H 2 O as a liquid chromatograph.
As shown in Table 2, it was confirmed that the combination preparation of the example to which the alkalizing agent was added exhibited excellent stability because the rate of increase of the flexible substance C of S-omeprazole was smaller than that of the comparative example in which the alkalizing agent was not added.
Experimental Example 3: Stability test of preparations containing rabeprazole, omeprazole, lansoprazole, and pantoprazole
The stability tests were conducted on the combination preparations prepared in Examples and Comparative Examples.
Specifically, each of the above-mentioned formulations was packed with 1 g of silica gel in an HDPE bottle and stored at 50 ° C and 85% RH. After 3 months of the above conditions, the content of total flexible substances of PPIs rabeprazole, omeprazole, lansoprazole and pantoprazole was measured by liquid chromatogram.
Inhibitor
As shown in Table 2 and Table 3, it was found that the combination agent of the example in which the alkalizing agent was added did not add the alkalizing agent or added less than 1 part by weight of the proton pump inhibitor, Respectively.
