Description

) 15 20 25 30 35 448, 31112 2 Ändamålet med föreliggande uppfinning är således att åstadkomma en farmaceutisk komposition som har hög löslighet och överlägsen depåverkan genom att blanda ett läkemedel, polyetenoxid och minst ett basämne (l:a komponent) valt bland hydroxipropylmetylcellulosa, hydroxipropylcellulosa, polyvinylpyrrolidon, karboxi- vinylpolymer och hydroxipropylmetylcellulosaftalat.
Denna farmaceutiska komposition kan vidare innehålla minst ett basämne (2:a komponent) valt bland ytaktiva medel och polyetylenglykol.
Den farmaceutiska kompositionen av ett fast läke- mvd~i mflu dvpavurkanlenlrgt ändamålet med förelig- gande uppfinning kan erhållas genom följande metod.
Ett fast läkemedel och ovanstående basämne(n), dvs den l:a komponenten (de lza komponenterna) eller den lza komponenten (de 1:a komponenterna) och den 2:a komponenten (de_2;a komponenterna) löses i ett organiskt lösningsmedel, såsom metanol, etanol, kloroform, di? klormetan, ensamma eller i kombination, eller vatten och därefter avlägsnas lösningsmedlet. Avlägs- nandet av lösningsmedlet genomföras genom torkning under reducerat eller normalt tryck, spraytorkning, granuleringstorkning i fluidicerad bädd eller lyofi- lisering etc. Genom ovanstående förfaranden erhålles ett fint pulver eller granuler med fin kornstorlek, i vilka ett fast läkemedel är löst eller homogent dis- pergerat i amorf form i basämnet (basämnena). Därefter tillsättes polyetenoxid till det fina pulvret eller granulerna med liten kornstorlek som sålunda erhållits följt av blandning av dessa för att åstadkomma den farmaceutiska kompositionen med depåverkan enligt föreliggande uppfinning.
Denna farmaceutiska komposition kan även erhållas genom att tillsätta polyetenoxid och basämnet (bas- ämnena), dvs den lza komponenten (de l:a komponenterna) eller den lza komponenten (de lza komponenterna) och den 2:a komponenten (de 2:a komponenterna) sam- 'fßx & 'w <1 glo 15 20 '25 _30 35 . 448 542 3 tidigt- varvid polyetenoxid blir homogent löst eller I, dispergerat med ett *fast läkemedel i basämnet (bas- ämnena).
Som det fasta läkemedlet i förgliggande uppfinning ':aÜVänÖS ett läkemeåel med låg eller hög löslighet *alltefter vad som önskas för att kvarhållas i mag-tarm- kanalen nnder lång tid.-Dessa läkemedel omfattar nicardi- Pin, ett nicardipínsalt, exempelvis nicardípinväteklorid,o nifedipin eller indometacin. 7 _'fSom det ytaktiva medlet som det 2:a ämnet kan nämnas anjoniska vtaktiva medel, såsom natriumalkyl- sulfat, nonjoniska ytaktiva medel, såsom polyokietylen- sorbitanfettsyraester, polyoxietylenfettsyraester, _nolyoxietylenricinoljaderivat etc. _ ,'Blandningsförhållandet för varje komponent i den-farmaoeutiska'kompositionen'varierargalltefter typen av det fiasta läkemedlet eller dess administra- tionsdos. Vanligen är det lämpligt att använda 0,5 - 20: viktdelar, företrädesvis l -llÖ viktdelar av den l:a komponenten (de l;a komponenterna), 0,05 - lo vikt- ïdelar, företrädesvis 0,1 - 5 viktdelar av den 2:a komponenten (de 2:a komponenterna), per_viktdel av gadet fasta läkemedlet. Blandningsförhållandet för gpolyetenoxid är lämpligen 0,1 - 50 viktdelar, före- trädesvis 0,5 -'30 viktdelar per viktdel av den totala mängden fast läkemedel, lta komponent (lza komponenter) eoch°2:a'komponent'(2:a komponenter)§ Den farmaoeutiska kompositionen med depåverkan §>som sålunda erhållits kännetecknas av att polyeten- oxid är inblandad i det fina pnlvret eller granu- g-lerna med den Jilla kornstorleken, 1 vilket ett fast *läkemedel föreligger i amorf form. Hittills har poly-- etenoxid"använts_som ett beläggningsmedel eller ett bindemedel vid framställningen av farmaceutiska kom- positioner, men_det har inte angivits att en farma- ceutisk komposition med depåverkan kan erhållas genom 448 542? 10 15 20 25. 4 latt blanda in palyetenoxid l ett fast läkemedel l amerf form; såsom vid fiöreliggande fippfinning. Den farfiacettiska kompesitienen med depåverkan enligt föreliggande uppfinning kan inte endast åstadkomma ä depåverkangütan_även god adsorberingsföpmåga för ett läkemedel, varför een get hög biotillgänglighet e ,(ÜbieaVailabilityf). __Depifarmaceptiska tempositiohenwenligt_ferelig~ 7 gahde_fippfihning_kan i fitaktiken användas genom att formas till pplVerL_g;anpler} tabletter} piller, kaps- _la; Få konyentipnellt gått.
