Description
Legemiddeltilberedninger tilMedicinal preparations for
oral diabetes-behandling.oral diabetes treatment.
Oppfinnelsens gjenstand er en l^gemiddeltilberedningThe object of the invention is a pharmaceutical preparation
til oral diabetes-behandling og en fremgangsmåte til dens; fremstilling. for oral diabetes treatment and a method thereof; manufacture.
Spesielt vedrører oppfinnelsen en terapeutisk tilbeæd-ning, bestående av en' fast kombinasjon av N-4.-V~~2-(5-klor-2-metoksy-benzamido)-etylZ-fenyl-sulfonyl-N'-cykloheksylurinstoff(kalt Glibenclamid) og l-(2-fenyletyl)-biguanid-hydroklorid (kalt fen-forminhydroklorid), eller et farmasøytisk anvendbart salt herav. In particular, the invention relates to a therapeutic dressing, consisting of a fixed combination of N-4.-V~2-(5-chloro-2-methoxy-benzamido)-ethylZ-phenyl-sulfonyl-N'-cyclohexylurea (called Glibenclamide) and 1-(2-phenylethyl)-biguanide hydrochloride (called phenformin hydrochloride), or a pharmaceutically usable salt thereof.
Diabetikeren som ikke behøver insulin og som reagerer utilstrekkelig på diett alene, behandles i tillegg med orale medi-kamenter. Hertil anvendes sulfonylurinstoffer, hvis hovedsakelige virkningsmekanisme består i frigjøring av endogen insulin eller biguanide preparater, som i det vesentlige ved en hemming av gluko- rieogenensen ved en økning av det anaerobe glukosestoffskifte i legemsperiferien og ved en-hemning av den intestinale :glukosere-sorpsjon senker sukkersykes blodsukkerspeil. Diabetics who do not need insulin and who respond insufficiently to diet alone are additionally treated with oral medications. For this, sulfonylureas are used, whose main mechanism of action consists in the release of endogenous insulin or biguanide preparations, which essentially by inhibiting glucoreogenesis by increasing anaerobic glucose metabolism in the body's periphery and by inhibiting intestinal glucose absorption lowers diabetic's blood sugar level.
Den fri kombinasjon, dvs. adskilt administrering av sulfonylurinstoff- og biguanidpreparater, har i lengere tid vist seg egnet i terapien av diabetikere, som ikke reagerer på en sulfo-nylurinstof f-monoterapi. Ved en stor prosentsats kan karbohydrat-stof f skifte rekompenseres ved en kombinas j onstérapi'. På grunn av deres, forskjellige virkningsmekanisme kompletterer de betazytotrope stoffer og biguanider seg méd hensyn til den antidiabetiske effekt. The free combination, i.e. separate administration of sulfonylurea and biguanide preparations, has for a long time proved suitable in the therapy of diabetics who do not respond to a sulfonylurea monotherapy. In the case of a large percentage, carbohydrate-substance replacement can be compensated by a combination therapy. Due to their different mechanism of action, the betazytotropic substances and biguanides complement each other with regard to the antidiabetic effect.
Ved en terapi.med begge stoffer i fri kombinasjon fremkommer en additiv effekt på blodsukkersenkningen. Det er omtalt fordelen av en slik kombinert terapi; deri viser seg spesielt egnet ved svikt i en sulf onylurinstof f-monoterapi'. Således omtales at den kombinerte behandling ved 50% av senmangler muliggjorde og ved mer enn to. år videreføringen av en tablettbehandling. In a therapy with both substances in free combination, an additive effect on the lowering of blood sugar appears. The advantage of such a combined therapy is discussed; therein proves to be particularly suitable in case of failure of a sulphonylurea monotherapy'. Thus, it is mentioned that the combined treatment enabled 50% of tendon defects and more than two. years the continuation of a tablet treatment.
Enskjønt det av en fast'kombinasjon i forhold til den fri var det ikke å vente noen prinsippielle fordeler, ble det overraskende funnet at den faste-kombinasjon ifølge oppfinnelsen av fenforminsalt.og glibenclamid. ikke bare har fordelene med den fri kombinasjon,, men at kombinasjonsapparatets .virkning overgår' virkningen av den adskilte, administrering av begge komponenter. Although no advantages in principle were to be expected from a fixed combination compared to the free one, it was surprisingly found that the fixed combination according to the invention of phenformin salt and glibenclamide. not only has the advantages of the free combination,, but that the effect of the combination apparatus exceeds that of the separate administration of both components.
Av et kombinasjonspreparat, som har en slik syner-gistisk virkning, må glibenclamidet.med .en gang i maven frigjøres og fenforminsaltet frigjøres protrahert. Dette oppnås ved at man sammenfatter de to virksomme stoffer i en do ser in gs enhet, hvori fenforminsaltet: foreligger i retardert, form og glibenclamid i mave-saftoppløselig form. Of a combination preparation, which has such a synergistic effect, the glibenclamide must be released immediately in the stomach and the phenformin salt released protractedly. This is achieved by combining the two active substances in one dosage unit, in which the phenformin salt: is available in a retarded form and glibenclamide in a gastric juice-soluble form.
Spesielt, foretrukket er tosjiktstabletter, drasjeer eller manteltabletter, idet begge sistrevnte kjerner består av fenforminsalt i retardert form, hvorpå glibenclamid pådrasjeres resp. som ommantles med glibenclamid. In particular, two-layer tablets, coated tablets or coated tablets are preferred, as both last-cracked cores consist of phenformin salt in retarded form, on which glibenclamide is applied respectively. which is coated with glibenclamide.
Fremstillingen av tilberedningene foregår etterThe preparation of the preparations takes place after
i og for seg kjente metoder.per se known methods.
Penforminsaltet innleires fortrinnsvis i en voks-matrdls med vanlige bærestoffer og frigjøringsregulerende stoffer, som eksempelvis natriumklorid, natriumcitrat, natrium- e'ller kaliumfosfat eller spesielt melkesukker. Som voks egner det seg naturlige, og syntetiske, som. f.eks .. bievoks eller montan-estervoks . Av de angjeldende bærestoffer skal det eksempelvis nevnes: Kalsiumfosfat.eller -sulfat og aluminiumoksyd samt spesielt aluminiumhydroksyd. The penformin salt is preferably embedded in a wax matrix with usual carriers and release-regulating substances, such as sodium chloride, sodium citrate, sodium or potassium phosphate or especially milk sugar. Natural and synthetic waxes are suitable, such as eg .. beeswax or montan ester wax . Of the carrier substances in question, examples should be mentioned: Calcium phosphate or sulphate and aluminum oxide and especially aluminum hydroxide.
Dosrelasjonen av enkeltkomponenter glibenclamid The dosage relationship of individual components glibenclamide
f enforminsaltet utgjør fortrinnsvis 1 : 10, Preparater, som inneholder 2,5 til 5S0 mg glibenclamid og 25 til 50 mg fenforminhydro-klorid er foretrukket. Ved den høyere virksomme, stoffdose har to-sjiktstablettene vist seg som spesielt fordelaktige. The phenformin salt is preferably 1:10. Preparations containing 2.5 to 550 mg glibenclamide and 25 to 50 mg phenformin hydrochloride are preferred. At the higher effective drug dose, the two-layer tablets have proven to be particularly advantageous.
Den synergistiske virkning.av de to virksomme stoffer i en tilberedning ifølge oppfinnelsen kunne vises ved hjelp av følgende undersøkelser: Det i undersøkelsen anvendte preparat inneholdt i form av en tosjiktstablett pr. enhet 2,5 mg glibenclamid til om-gående frigjøring og 25' mg fenformin-hydroklorid innleiret i et retardasjonssjikt til protrahert frigjøring, (ifølge eksempel 1). The synergistic effect of the two active substances in a preparation according to the invention could be demonstrated with the help of the following investigations: The preparation used in the investigation contained in the form of a two-layer tablet per unit 2.5 mg glibenclamide for immediate release and 25 mg phenformin hydrochloride embedded in a retardation layer for prolonged release, (according to example 1).
Det ble i første rekke beregnet hvilke dose glibenclamid og av et biguanid (100 mg buformin og 500 mg metformin ble satt likt med 50 mg.fenformin) tilsvarte en bestemt innstillings - kvalitet før omstilling på kombinasjonspreparatet.. Deretter ble alle pasienter oppdelt i samme innstillingskvalitet. etter deres dose, som beregnet samlet dose og dividert med det eventuelle tilfelleantall. It was primarily calculated which dose of glibenclamide and of a biguanide (100 mg buformin and 500 mg metformin were added equally to 50 mg phenformin) corresponded to a specific setting quality before switching to the combination preparation. Then all patients were divided into the same setting quality . according to their dose, as calculated total dose and divided by the possible number of cases.
Den kliniske undersøkelse av tilberedningen ifølge oppfinnelsen førte til det overraskende resultat at ved diabetikere, som under den forangående. frie kombinasjonsterapi har meget god resp. god innstillingskvalitet, kunne det oppnås en dosisinnsparing. The clinical examination of the preparation according to the invention led to the surprising result that in diabetics, as under the preceding. free combination therapy has very good resp. good setting quality, a dose saving could be achieved.
Med administrering av de to i en legemiddelform kombinerte virksomme stoffer fremkommer en farmakologisk synergisme. With the administration of the two active substances combined in a pharmaceutical form, a pharmacological synergism emerges.
Den spesielle fordel ved denne tilberedning ligger altså i at den ønskede terapeutiske virkning oppnås med doser som-ligger under de som er nødvendige' for behandling med de enkelte komponenter. The particular advantage of this preparation therefore lies in the fact that the desired therapeutic effect is achieved with doses which are below those necessary for treatment with the individual components.
Tabell 1 viser den tydelige redusering av begge kompp-nenter (ca. 1/3) ved de "meget godt" til "godt" innstilte pasienter. Table 1 shows the clear reduction of both components (approx. 1/3) in the "very good" to "good" adjusted patients.
Som ytterligere fordel ved kombinasjonstilberedningen i forhold til administrering av enkeltkomponentene:er det å fremheve at antallet av "måtelig" innstilte som også "sviktende" betegnede As a further advantage of the combination preparation in relation to the administration of the individual components: it is worth emphasizing that the number of "moderately" adjusted as well as "failingly" designated
diabetikere ble nedsatt.diabetics were reduced.
Også ved diabetikere som under overnevnte terapi viste en bedre enn "måtelig" innstilling, bedret stoffvekseltil-standen seg etter omstilling på tilberedningen ifølge oppfinnelsen. Noen insulinpasienter kunne likeledes omstilles til glibenclamid-fenformin-tilberedningen. Also in diabetics who during the above-mentioned therapy showed a better than "moderate" attitude, the metabolic state improved after switching to the preparation according to the invention. Some insulin patients could also be switched to the glibenclamide-phenformin preparation.
Preparatet har vist seg spesielt egnet ved eldre (ofte glemske) pasienter. Her kommer fastkombinasjonen spesielt til fordel, fordi den nedsetter faren for å glemme resp. feilinntak av to -adskilt anordnede komponenter, som det må regnes med ved enhver permanent medikasjon. Ulemper ved denne fastkombinasjon ble ikke iakttatt. ' The preparation has proven particularly suitable for elderly (often forgetful) patients. Here, the fixed combination is particularly beneficial, because it reduces the risk of forgetting or wrong intake of two separately arranged components, which must be taken into account with any permanent medication. Disadvantages of this fixed combination were not observed. '
Av fenformin er det kjent at det fra en bestemt individuell forskjellig dosis, overveiende kan frembringe gastrointestinale bivirkninger. En spesiell fordel ved den galeniske applikasjonsform ifølge oppfinnelsen er å se i at den i en voksmatriks innleirede fenformin-hydrokloriddel frigjøres protrahert og således reduseres de gastrointestinale ubehag til et minimum. I motsetning hertil er det ønskelig med en hurtig frigjøring av glibenclamid.. Begge krav oppfylles av tilberedningen ifølge oppfinnelsen. Of phenformin, it is known that from a certain individual different dose, it can predominantly produce gastrointestinal side effects. A particular advantage of the galenic application form according to the invention is that the phenformin hydrochloride part embedded in a wax matrix is released protractedly and thus the gastrointestinal discomfort is reduced to a minimum. In contrast, a rapid release of glibenclamide is desirable. Both requirements are met by the preparation according to the invention.
