Definitions
- the present invention relates to a sustained-release tablet of cilostazol, a pharmacologically active ingredient prepared using a release controlling polymer, which can be administered once a day and controls the dissolution rate of cilostazol consistently even at pH changes, thereby causing headache and duplex.
- the present invention relates to a cilostazol sustained-release tablet which reduces side effects of cilostazol such as persimmon and tachycardia, thereby improving the convenience of taking a tablet.
- Cylostazol (6- [4- (Cyclohexyl-1H-tetrazol-5-yl) butoxy] -3,4-dihydro-2 (1H) -quinolinone (Formula 1)) is a quinolinone-based substance.
- the phosphodiesterase type plateodiesterase type
- Cilostazol inhibits primary aggregation of platelets induced by ADP, epinephrine and the like in platelets isolated from mice, rats, rabbits, dogs and humans and dissociates platelet aggregates.
- oral administration to beagle dogs inhibits aggregation of platelets induced by ADP and collagen, and when administered orally to patients with chronic arterial obstruction (Berger's disease, obstructive atherosclerosis, diabetic peripheral angiopathy, etc.).
- the platelet aggregation inhibitory effect of cilostazol is rapidly expressed after administration, and the effect is maintained even in repeated administration. Inhibition of platelet aggregation at the time of discontinuation is restored to pre-administration values with a decrease in plasma concentration, and no rebound phenomenon is observed.
- cilostazol The mechanism of action of cilostazol is as follows. It inhibits the release of serotonin from platelets in rabbits but does not affect the entry of serotonin, adenosine, into platelets. It inhibits platelet aggregation by TXA2 (thromboxane A2) without affecting arachidonic acid metabolism of platelets. This is due to the inhibition of cAMP-PDE (cyclic AMP phosphodiesterase) activity of platelets and vascular smooth muscle, resulting in antiplatelet action and vasodilation.
- cAMP-PDE cyclic AMP phosphodiesterase
- cilostazol formulations are not only poor patient compliance, but also cilostazol immediate release formulations result in rapid and uneven drug release upon oral administration. It is known to cause side effects such as headache, headache, tachycardia and the like (see Am J Cardiol 2001; 87 (suppl): 28D-33D and US Patent Publication No. 2002/0058066).
- cilostazol is poorly soluble and its absorption rate decreases toward the lower part of the small intestine, the overall bioavailability may be reduced in the case of conventional release control formulations, and PCT Patent Publication No. WO 2000/57881 discloses cilostas in the form of fine powder.
- a method is disclosed for increasing the small intestinal uptake of cilostazol using a formulation in the form in which the sol is dispersed and / or dissolved in combination with a dispersing agent and / or a solubilizing agent.
- the present invention has the advantage of the matrix form of the water-soluble polymer that has been used in the conventional sustained-release formulation to solve the problems of the prior art for cilostazol sustained-release tablet, and in addition, a separate control system in the intestine acts to release the drug It is an object of the present invention to provide an agent which suppresses the expression of side effects as the control is made constant and precisely, and thus the blood concentration in vivo is kept constant.
- the cilostazol sustained-release tablet containing cilostazol, a release controlling polymer, a binder, a filler and a lubricant is a hydroxypropylmethylcellulose, carbomer, hydroxypropylcellulose, methyl One or a mixture of two or more selected from the group consisting of cellulose, polyvinylpyrrolidone and polyvinyl alcohol.
- the release controlling polymer contained in the cilostazol sustained-release tablet is a mixture of hydroxypropyl cellulose and carbomer.
- the mixture of hygipropyl cellulose and carbomer contained in the cilostazol sustained-release tablet is included in 25 to 50% by weight based on the total tablet weight.
- the viscosity of hydroxypropylmethylcellulose which is a release controlling polymer included in the cilostazol sustained-release tablet, is 80,000 cps to 120,000 cps.
- the weight mixing ratio of the hydroxypropylmethylcellulose and carbomer mixture contained in the cilostazol sustained-release tablet is 1: 1 to 20: 1.

- Example 5 is a result of measuring the dissolution rate according to the pH of Formulations 6 to 9 of Example 5 of the present invention.
- the present invention relates to a sustained-release tablet containing cilostazol. Specifically, by extending the elution time to allow once-a-day administration, controlling the release of the drug with an aqueous matrix system, and controlling the release of the drug according to pH, the absorption of the drug from the stomach to the intestine is constantly and precisely controlled. By providing controlled release, the cilostazol sustained-release tablet which improves the convenience of taking women, the elderly, and children by suppressing the expression of the side effect of cilostazol is provided.
- the cilostazol sustained-release tablet according to the present invention contains cilostazol, a release controlling polymer, a binder, a filler and a lubricant.
- Any pharmaceutically acceptable polymer can be used as a release controlling polymer.
- Cellulose derivative composed of sodium carboxymethylcellulose, propylene oxide and its derivatives, polyvinylpyrrolidone (molecular weight 90, trade name Povidone K-90), polyethylene glycol, polyvinyl alcohol ( Polyvinyl alcohols, polyvinylacetate, polyvinylacetate phthalate, polymethacrylate, polymethacrylate polymers (commercially Eudragit , polyacrylic acid, polymethacrylate) Rate It may be one or a mixture of two or more selected from the group consisting of derivatives (typically carbomer), glycerol monostearate and poloxamer, preferably hydroxypropylmethylcellulose, carbomer, hydroxypropylcellulose, methylcellulose One or two or more mixtures selected from the group consisting of polyvinylpyrrolidone and polyvinyl alcohol may be used, and more preferably, a mixture of hydroxypropyl cellulose and carbomer may be used
- the ratio of the total tablet weight of the release controlling polymer included in the cilostazol sustained-release tablet according to the present invention is preferably 25% to 50%. If the proportion of the release controlling polymer is less than 25% by weight, the release time of cilostazol is shortened and the amount of elution per unit time is increased, which may cause side effects.If it exceeds 50% by weight, the cilostazol release time is long and the drug per unit time. Because of the small amount of elution, sufficient efficacy cannot be expected.
- Sustained-release tablets that delay the dissolution of pharmacologically active ingredients are prepared by mixing a release controlling polymer, and generally, methyl cellulose, ethyl cellulose, hydroxymethyl cellulose, and polyvinylpyrrolidone are used as the release controlling polymer.
- the present inventors found that when carbomers are mixed with a general release control polymer in the preparation of a sustained-release tablet, a long dissolution time and a constant drug dissolution pattern are shown compared with a single release release polymer. In addition, it was found that the dissolution pattern can be controlled by adjusting the weight ratio of the release control polymer other than the carbomer and the carbomer.
- Hydroxypropylmethyl cellulose can ensure a long dissolution time by forming a matrix (matrix) to prevent the rapid dissolution of the pharmacologically active ingredient in the tablet. In addition, it shows a uniform dissolution pattern compared to other emission control polymers.
- Sustained-release tablets containing pharmacologically active ingredients show swelling of the tablet during elution.
- the matrix of the release control polymer is not strong, the matrix may be partially damaged (erosion), which may cause the tablet to disintegrate, which may lead to rapid drug release and cause headache or flushing in the patient.
- a mixture of high viscosity hydroxypropyl methyl cellulose and carbomer was used as a release controlling polymer.
- Carbomer is a release-controlling polymer that exists in sol state in acidic condition and drug release is maintained by hydroxypropylmethylcellulose system, and in small intestine in alkaline condition, it is in hydrogel state and release of drug. To control.
- the hydroxypropyl methyl cellulose used in the present invention has a viscosity of 80,000 cps to 120,000 cps, preferably hydroxypropyl methyl cellulose having a viscosity of 90,000 cps to 110,000 cps. If the viscosity is less than 80,000 cps, then a large amount of hydroxypropylmethylcellulose is required to increase the tablet size, and if the viscosity is more than 120,000 cps, uniform mixing with cilostazol becomes difficult. Even if the viscosity is the same, the particle crushing degree is more uniform and the physical form (Physical form) with excellent dispersion is used.
- the mixed weight ratio of hydroxypropylmethylcellulose and carbomer contained in the cilostazol sustained-release tablet according to the present invention is 1: 1 to 20: 1. If the ratio is less than 1: 1, it is difficult to form a matrix in the tablet, and the delay of drug release is lowered. If the ratio is more than 20: 1, the dissolution rate of cilostazol is lowered under alkaline conditions, and it is difficult to uniformly mix the cilostazol and the release controlling polymer. Preferably a mixture of 1.5: 1 to 10: 1 is possible.
- Cilostazol sustained-release tablet according to the present invention shows a constant dissolution rate according to the change of pH. Sustained-release tablets administered orally will stay in the human body for more than 8 hours, especially in the stomach and the small intestine, which has a long pH, so the sustained-release tablet should maintain a constant dissolution rate according to pH.
