Abstract
The invention concerns a matrix object for prolonged release of trimetazidine or one of its additive salts to a pharmaceutically acceptable acid after oral administration, characterised in that the prolonged release is controlled by the use of a polymer derived from cellulose.
Description
12121 - 1 -
The présent invention relates to a matrix tablet enabling the prolongée! release oftrimetazidine, or an addition sait thereof with a pharmaceutically acceptable acid, afteradministration by the oral route.
Trimetazidine, or l-(2,3,4-trimethoxybenzyl)piperazine, is a compound which, by5 maintaining the energy metabolism of a cell exposed to hypoxia or ischaemia, avoids thecollapse of the intracellular level of adenosine triphosphate (ATP). It thus ensuresfunctioning of the ion pumps, and sodium-potassium transmembrane flows and maintains cellular homeostasis.
Trimetazidine dihydrochloride is currently used therapeutically for the prophylactic 10 treatment of angina pectoris crisis, in chorioretinal attacks and for the treatment of vertigoof vascular origin (Ménière's vertigo, tinnitus).
Trimetazidine dihydrochloride has, until now, been administered by the oral route at dosesof from 40 to 60 mg/day, in the form of tablets containing 20 mg of active ingrédient or adrinkable solution containing 20 mg of active ingrédient per ml. Those two forms are 15 immediate-release forms. Patent FR 2 490 963 describes the immediate-release tablet form.Trimetazidine dihydrochloride is rapidly absorbed and eliminated by the body, its plasmahalf-life being less than 6 hours, which means that administration of the active ingrédienthas to be split into 2 or 3 administrations per day in order to ensure sufficient plasmalevels. The dosage regimen most frequently required during treatments is three tablets per 20 day. Multiple daily administrations bear the risk of being forgotten both by patients leadingan active life and by elderly patients already taking a number of médications.
Because of the rapid absorption and the 6-hour half-life, such immediate-release formsresuit in low levels in the blood by the time of the next administration. It is known to beimportant to maintain effective myocardial protection throughout the 24-hour period and 25 especially in the early moming when the conséquences of ischaemia are most serious.Because complété coverage of the day is not achieved with the immediate-release form, theApplicant has developed a prolonged-release form enabling perfect 24-hour coverage,ensuring a sufficient level in the blood between two administrations whilst retaining a large 1 2121 - 2 - plasma peak after each administration so as to maintain the efficacy of the trimetazidine,maintaining the energy metabolism of a cell exposed to hypoxia or ischaemia and avoidingthe lowering of the intracellular level of ATP.
It also allows peripheral vasodilator effects to be avoided, while stabilising blood flow5 rates and tensional effects.
The new formulation according to the invention accordingly allows the positivecharacteristics of the formulation described in patent FR 2 490 963 to be retained whileenabling better coverage of the day, which leads to better compliance and permanentprotection. 10 The présent invention relates more especially to a matrix tablet which enables theprolonged release of trimetazidine, or a pharmaceutically acceptable sait thereof, afteradministration by the oral route and which is composed of a hydrophilic matrixcharacterised in that the prolonged release is controlled by the use of a cellulose dérivativepolymer. 15 This matrix tablet, administrable preferably twice a day, enables prolonged activeingrédient release to be obtained whilst retaining a large plasma peak on eachadministration. It allows plasma levels greater than 70 pg/l to be obtained in humans aftereach administration and a plasma level greater than or equal to 40 pg/l to be maintaineduntil the next administration, which was not the case with the tablet described in patent 20 FR 2 490 963 when administered 3 times per day.
Among the cellulose dérivatives used in the matrix according to the invention, there maybe mentioned, more especially, cellulose ethers such as hydroxypropylcellulose,hydroxyethylcellulose, hydroxymethylcellulose, methylcellulose and hydroxypropylmethylcellulose. 25 The cellulose dérivative is preferably hydroxypropyl methylcellulose. The percentage ofcellulose dérivative polymer is from 25 to 50 % of the total mass of the tablet. -3- 12121
Hydroxypropyl methylcelluloses that hâve a viscosity of from 100 cP to 100 000 cP maybe used. The preferred viscosity is 4 000 cP.
Various excipients are added to the hydrophilic matrix, for example binders, diluents,lubricants and ilow agents. Among the binders, polyvidone is preferably used. The 5 percentage of polyvidone is from 3 to 12 % of the total mass of the tablet. Among thediluents, calcium hydrogen phosphate dihydrate is preferably used, which provides betterfluidity and better compressibility than other diluents such as lactose monohydrate. Thepercentage of calcium hydrogen phosphate is from 25 to 75 % of the total mass of thetablet. 10 Among the lubricants, there may be mentioned, without implying any limitation,magnésium stéarate, stearic acid, glycerol behenate and sodium benzoate. The preferredlubricant is magnésium stéarate. Finally, colloïdal silica is preferably used as flow agent.
The trimetazidine used in the matrix tablets according to the invention is preferably in thedihydrochloride form. 15 The percentage of trimetazidine dihydrochloride is from 15 to 30 % of the total mass of thetablet, preferably from 15 to 18 %.
The person skilled in the art will generally consider the release kinetics of matrix tablets tobe dépendent on the nature and amount of the basic component of the matrix - in this case,namely, the cellulose dérivative. 20 It now appears, surprisingly, that the release kinetics of the matrix tablet according to theinvention are influenced neither by the amount nor by the grade of the cellulose dérivativeused.
Various formulations produced using, on the one hand, hydroxypropyl methylcelluloses ofdifferent viscosities and, on the other hand, variable amounts of the same grade of 12121 -4- hydroxypropyl methylcellulose hâve exhibited équivalent release kinetics, which impliesthat there exists a spécifie synergy between the cellulose dérivative and the trimetazidine.
The présent invention relates also to a process for the préparation of the matrix tablet. Thematrix tablet may be prepared by wet granulation followed by compression, by dry 5 granulation followed by compression, or by direct compression. The préparation process ispreferably wet granulation followed by compression.
The wet granulation is performed by mixing the trimetazidine, the polyvidone and thediluent, and then wetting that mixture. That first step enables a hydrophilic environment tobe created around the active ingrédient, which is bénéficiai for its dissolution, and also 10 enables a unit dose that is as uniform as possible to be obtained.
In a second step, the previously obtained granulate is mixed with the cellulose dérivative.The lubricant and the flow agent are then added to the mixture. The third step iscompression of the lubricated mixture previously obtained.
The tablets thus formed are then, if desired, coated according to a conventional coating15 technique.
The following Examples illustrate the invention but do not limit it in any way. The matrixtablets described in the Examples were prepared in the following manner : - Step A : Mixture of trimetazidine, polyvidone and calcium hydrogen phosphate dihydrate,then wetting of the mixture using a sufficient amount of purified water, granulation and 20 then drying of the granulate. ' B : Mixture of the granulate obtained in Step A with hydroxypropyl methylcellulose. " Imbrication of the mixture obtained in Step B with magnésium stéarate and colloïdal silica. 12121 - 5 - - Step D : Compression of the lubricated mixture obtained in Step C on a rotary tabletmachine so as to obtain tablets having a hardness of about from 40 to 160 N, measured bybreaking across a diameter.

The plasma kinetics were studied after administration of the matrix tablet of formulation F3described in Example 1 to 12 healthy volunteers. 5 Administration was carried out for 4 days at the rate of two tablets per day.
The plasma kinetics of the tablet of formula F3 were compared to those of an immediate-release (IR) tablet administered for 4 days at the rate of three tablets per day.
The unitary formulation of the immediate-release (IR) tablet is as follows :Trimetazidine dihydrochloride................................................................................20 mg 10 Maize starch............................................................................................................26 mg
Mannitol..................................................................................................................34 mg
Polyvidone.................................................................................................................4 mg
Magnésium stéarate...................................................................................................1 mg
Talc............................................................................................................................5 mg 15 The average plasma concentration is given in Figure 1. 1 2121
Figure 1 : Plasma kinetics of trimetazidine
Average plasma concentrations of trimetazidine (in μg/l) after oral administration of the F} form and an IR form to 12 healthy volunteers
Plasma
Time (h) 5 This curve clearly shows that the F3 form enables prolonged release of trimetazidine to beobtained while retaining a large plasma peak on each administration.
The plasma level observed after each administration is close to 90 pg/l and hardly differentfrom that obtained with the IR form. At the end of 24 hours the plasma level is greater than40 pg/l whereas, with the immediate-release formulation, it is only about 25 pg/l.
