Description
Foreliggende oppfinnelse vedrører nye salter av forbindelsen alprenolol som er en terapeutisk aktiv forbindelse som benyttes ved behandling av hjertelidelser, som f.eks. hypertensjon, The present invention relates to new salts of the compound alprenolol, which is a therapeutically active compound used in the treatment of heart disorders, such as e.g. hypertension,
angina pectoris og arrytmier. Den farmakologiske virkningen av alprenolol bevirkes ved blokkade av betareseptorer i det autonome nervesystemet. I orale farmasøytiske preparater anvendes alprenolol som hydrogenkloridet. Imidlertid har alprenololhydrogenklorid en sterk lokal irriterende virkning. angina pectoris and arrhythmias. The pharmacological action of alprenolol is caused by blockade of beta receptors in the autonomic nervous system. In oral pharmaceutical preparations, alprenolol is used as the hydrogen chloride. However, alprenolol hydrogen chloride has a strong local irritant effect.
Et antall sårdannelser i spiserøret hos pasienter er rapportert. Forsøk på å elliminere disse bivirkningene ved å benytte belagte A number of esophageal ulcers in patients have been reported. Try to eliminate these side effects by using coated
tabletter har foreløpig ikke vært vellykkede.tablets have so far not been successful.
Formålet med foreliggende oppfinnelse er å tilveiebringe alprenolol i en form som forhindrer de nevnte bivirkningene samtidig som en høy absorbsjon av medisinen fra gastrointestinalsystemet opprettholdes. The purpose of the present invention is to provide alprenolol in a form which prevents the aforementioned side effects while maintaining a high absorption of the medicine from the gastrointestinal system.
Alprenolol, som har det systematiske navnet 1-(2-allylfenoksy)-3-isopropylamino-2-propanol, er beskrevet i SE-C-214 378, Alprenolol, which has the systematic name 1-(2-allylphenoxy)-3-isopropylamino-2-propanol, is disclosed in SE-C-214 378,
GB-C-1 140 508, DE-C-1 294 955 og FR-C-1 479 614. Som salter GB-C-1 140 508, DE-C-1 294 955 and FR-C-1 479 614. As salts
er det foreslått hydrogenklorid, laktat, sulfat og sulfamat.hydrogen chloride, lactate, sulfate and sulfamate have been suggested.
For andre substituerte fenoksypropanolaminer har salter av tallrike syrer vært foreslått i generiske og spesifike termer. For other substituted phenoxypropanolamines, salts of numerous acids have been proposed in generic and specific terms.
For å redusere gastrointestinale bivirkninger av lokalt irriterende forbindelser har preparater med langsom frigivelse vært benyttet. Følgelig anvendes kaliumklorid med godt resul-tat i preparater kalt "Slow-K" og "Kalium Duretter". Preparater av denne typen som inneholder alprenololhydrogenklorid reduserer imidlertid ikke fargen for skade på spiserøret. Tvert imot er de fleste skadene som er rapportert forbundet med preparater med langsom frigivelse. Kompleks dannelse med karragenan for å redusere skader på spiserøret av emepronium, doksycyklin og propanolol er foreslått i EP-Al-0091409. Slike komplekser er tungt oppløslige i vann, men frigjør legemidlet i de sure omgivelsene i magen. Innholdet av legemiddel i disse kompleksene er lavere enn i de opprinnelige saltene. Dette kan forårsake problemer i tilfeller hvor man ønsker tabletter med høye doser. Foreliggende oppfinnelse tilveiebringer som nye salter saltene av alprenolol med benzosyre eller maleinsyre. Disse saltene finnes å være meget godt tålbare og forårsaker ikke skader på spiserøret. In order to reduce the gastrointestinal side effects of locally irritating compounds, preparations with slow release have been used. Consequently, potassium chloride is used with good results in preparations called "Slow-K" and "Kalium Duretter". However, preparations of this type containing alprenolol hydrogen chloride do not reduce the color of damage to the esophagus. On the contrary, most of the injuries reported are associated with slow-release preparations. Complexation with carrageenan to reduce esophageal damage by emepronium, doxycycline and propanolol is proposed in EP-A1-0091409. Such complexes are poorly soluble in water, but release the drug in the acidic environment of the stomach. The drug content in these complexes is lower than in the original salts. This can cause problems in cases where high-dose tablets are desired. The present invention provides as new salts the salts of alprenolol with benzoic acid or maleic acid. These salts are found to be very well tolerated and do not cause damage to the esophagus.
Videre er absorbsjonen av de nye saltene tilnærmet like høy som for hydrogenkloridet. Furthermore, the absorption of the new salts is approximately as high as for the hydrogen chloride.
Foretrukne salter er alprenololbenzoat og alprenololhydrogenmaleat. Mest foretrukket er alprenololbenzoat. Preferred salts are alprenolol benzoate and alprenolol hydrogen maleate. Most preferred is alprenolol benzoate.
De foretrukne saltene ifølge oppfinnelsen representeres ved formelen The preferred salts according to the invention are represented by the formula

Et farmasøytisk preparat for administrering av alprenolol via gastro-intestinalsystmet hvor alprenolol foreligger i form av et salt med benzosyre eller maleinsyre, er et ytterligere trekk ved foreliggende oppfinnelse. A pharmaceutical preparation for administering alprenolol via the gastro-intestinal system where alprenolol is present in the form of a salt with benzoic or maleic acid is a further feature of the present invention.
Orale farmasøytiske preparater av de nye•alprenololsaltene finnes å tilveiebringe de største fordelene sammenlignet med tidligere kjente orale alprenololpreparater, og følgelig utgjør slike orale preparater en foretrukket utførelse av oppfinnelsen. Imidlertid kan de nye saltene med fordel også benyttes i rektale farmasøytiske preparater. Oral pharmaceutical preparations of the new•alprenolol salts are found to provide the greatest advantages compared to previously known oral alprenolol preparations, and consequently such oral preparations constitute a preferred embodiment of the invention. However, the new salts can advantageously also be used in rectal pharmaceutical preparations.
De nye saltene ifølge oppfinnelsen kan formuleres til farma-søytiske preparater på en i og for seg kjent måte. De egner seg også for preparater med langsom frigivelse, fordi de har et høyt innhold av den aktive forbindelsen alprenolol. Det er følgelig mulig å fremstille både produkter som raskt absor-beres og produkter med en forlenget varighet. The new salts according to the invention can be formulated into pharmaceutical preparations in a manner known per se. They are also suitable for slow-release preparations, because they have a high content of the active compound alprenolol. It is therefore possible to produce both products that are quickly absorbed and products with an extended duration.
