Description
Foreliggende oppfinnelse gjelder vandige, farma-søytiske gelmaterialer for lokal bruk. The present invention relates to aqueous pharmaceutical gel materials for local use.
For utvikling av lokalt anvendbare gelmaterialerFor the development of locally applicable gel materials
for å fremme sårheling, er det viktig å ha et bærermateriale som utøver en positiv virkning på forløpet av sårheling, men ikke har noen fysiologisk irriterende effekt eller ikke har en retarderende effekt på helbredelsesprosessen. to promote wound healing, it is important to have a carrier material that exerts a positive effect on the course of wound healing, but does not have a physiologically irritating effect or does not have a retarding effect on the healing process.
Dette er ikke lett siden vevet i åpne sår er eks-tremt følsomt og også irriteres av ikke-aggressive fremmede materialer, som forsinker helbredelsesprosessen og forårsaker smerte hos pasientene. This is not easy since the tissue in open wounds is extremely sensitive and is also irritated by non-aggressive foreign materials, which delays the healing process and causes pain to the patients.
Det er et formål med foreliggende oppfinnelse å til-veiebringe et bærermateriale for lokale gelpreparater som It is an aim of the present invention to provide a carrier material for local gel preparations which
ikke utøver en irriterende effekt på skadet vev hos varm-blodige dyr og mennesker og således fremmer sårheling. does not exert an irritating effect on damaged tissue in warm-blooded animals and humans and thus promotes wound healing.
Det er nu funnet at hydroxyalkylcellulose utgjør et slikt bærermateriale som, i form av en vandig gelblanding (hydrogel), ikke utøver noen irriterende virkning på vev og, under visse omstendigheter, selv oppviser en helbredelses-fremmende effekt selv uten aktive materialer. It has now been found that hydroxyalkyl cellulose constitutes such a carrier material which, in the form of an aqueous gel mixture (hydrogel), exerts no irritating effect on tissue and, under certain circumstances, even exhibits a healing-promoting effect even without active materials.
Ifølge foreliggende oppfinnelse tilveiebringes således et farmasøytisk, vandig gelpreparat for lokal admini-strasjon som, som bærermateriale for et farmasøytisk aktivt materiale, inneholder en C^-Cg-alkylhydroxy-C-^-Cg-alkyl-cellulose eller en hydroxy-C^-Cg-alkylcellulose. According to the present invention, a pharmaceutical, aqueous gel preparation for local administration is thus provided which, as a carrier material for a pharmaceutical active material, contains a C₁-C₆-alkylhydroxy-C-₆-C₆-alkyl cellulose or a hydroxy-C₆- C 6 -alkyl cellulose.
Hydrogelen ifølge foreliggende oppfinnelse inneholder fortrinnsvis et helbredelses-fremmende, aktivt materiale som, i sin tur, ikke har en irriterende virkning på vev for ikke å oppheve fordelene ved bærermaterialet. The hydrogel according to the present invention preferably contains a healing-promoting active material which, in turn, does not have an irritating effect on tissue so as not to nullify the benefits of the carrier material.
Aktive materialblandinger ifølge DE patentActive material mixtures according to DE patent
3 416 777 er eksempelvis enestående egnet for dette formål, siden disse materialer i isotoniske preparater ikke bare har en virkning som i sterk grad hemmer sårhelbredelsen, men også på samme tid er forenelig med vevene uten noen irriterende virkning. 3 416 777 is, for example, uniquely suitable for this purpose, since these materials in isotonic preparations not only have an effect which strongly inhibits wound healing, but are also compatible with the tissues without any irritating effect.
Hydroxyalkylcelluloser skal forståes å være de celluloser som inneholder lavere alkylradikaler, dvs. de med opp til 4 og fortrinnsvis 1 eller 2 carbonatomer eller hydrogen- atomer og en lavere alkylradikal. Disse omfatter for eksempel methylhydroxymethylcellulose, methylhydroxypropyl-cellulose, butylhydroxymethylcellulose, ethylhydroxypropyl-cellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxybutylcellulose og methylhydroxyethylcellulose er foretrukket. Hydroxyalkylcelluloses shall be understood to be those celluloses which contain lower alkyl radicals, i.e. those with up to 4 and preferably 1 or 2 carbon atoms or hydrogen atoms and a lower alkyl radical. These include, for example, methylhydroxymethylcellulose, methylhydroxypropylcellulose, butylhydroxymethylcellulose, ethylhydroxypropylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxybutylcellulose and methylhydroxyethylcellulose are preferred.
Med celluloser skal det forståes de" som har et polymerisasjonstall på fra 120 til 1200, for eksempel slike som er kommersielt tilgjengelige under varenavnet "Tylose". Celluloses are to be understood as having a polymerization number of from 120 to 1200, for example those that are commercially available under the trade name "Tylose".
Disse danner klare geler med vann, kan belegges og, kan i en steril form som er så isotonisk som mulig, lett på-føres, sammen med passende doserte, aktive materialer, på såroverflater. These form clear gels with water, can be coated and, in a sterile form that is as isotonic as possible, can be easily applied, together with suitably dosed active materials, to wound surfaces.
Gelen kan fremstilles ved langsomt å innføre hydroxyalkylcellulosen i varmt vann under omrøring og tillate den å gelere inntil den er homogen. Midler for justering av den isotoniske tilstand, f.eks. natriumklorid, glycerol eller sorbitol, såvel som konserveringsmidler, f.eks. PBB-estere, kan på forhånd være tilsatt til vannet. The gel can be prepared by slowly introducing the hydroxyalkyl cellulose into hot water with stirring and allowing it to gel until it is homogeneous. Means for adjusting the isotonic state, e.g. sodium chloride, glycerol or sorbitol, as well as preservatives, e.g. PBB esters can be added to the water in advance.
Gelpreparatet kan vanligvis også blandes med andre blandinger, f.eks. olje-i-vann- eller vann-i-olje-emulsjoner, avhengig av bruksformålet, for å meddele en viss grad av lipofili til preparatene som kan hindre skorpedannelse på såroverflaten. The gel preparation can usually also be mixed with other mixtures, e.g. oil-in-water or water-in-oil emulsions, depending on the purpose of use, to impart a certain degree of lipophilicity to the preparations that can prevent crusting on the wound surface.
Ved fremstilling av gelpreparatet må det også ut-vises forsiktighet slik at et pH-område som er fordelaktig for sårhelbredelse på ca. 3,5 til 7,5 og fortrinnsvis fra 4 til 7 ikke underskrides eller overstiges. I forforsøk er det påvist at en sorbitol-holdig gel med pH på 4 er meget lett forenelig. When preparing the gel preparation, care must also be taken so that a pH range that is beneficial for wound healing of approx. 3.5 to 7.5 and preferably from 4 to 7 is not undercut or exceeded. In preliminary tests, it has been shown that a sorbitol-containing gel with a pH of 4 is very easily compatible.
Viskositeten skal, på basis av forholdet mellom cellulose og vann, være justert slik at gelen ikke strømmer for lett på den varme hudoverflate, og på den annen side. lett kan fordeles. En viskositet på fra 30 til 60 Pa.s later til å være fordelaktig. The viscosity must, on the basis of the ratio between cellulose and water, be adjusted so that the gel does not flow too easily on the warm skin surface, and on the other side. can easily be distributed. A viscosity of from 30 to 60 Pa.s appears to be advantageous.
