Abstract
Description
ïsïzozn-1 10 l5 20 25 30 Det har sålunda rests krav på en salva eller kräm, som ger anestesi genom intakt hud, varvid ett ytterligare sönskemål är att hålla koncentrationen av lokalanestetiskt medel låg för att undvika varje tendens till biverkningar. Thus, a requirement has been raised for an ointment or cream which provides anesthesia through intact skin, a further advantage being to keep the concentration of local anesthetic low to avoid any tendency to side effects.
Detta har nu överraskande blivit uppfyllt genom föreliggande uppfinning, som avser en emulsionssalvekomposition, inne- hållande från 0,5 viktprocent av åtminstone ett lokalaneste- tiskt medel och vilken kännetecknas av att det lokalaneste- tiska medlet i basform som sådan eller löst i en olja bildar oljefasen av en olja-i-vatten-emulsion, varvid koncentrationen av lokalanestetiskt medel i oljedropparna är sådan att oljan är huvudsakligen mättad med nämnda lokalanestetiska medel och att huvuddelen av oljedropparna har en storlek som inte överstiger l0 u, företrädesvis inte överstiger 3 p i diameter.This has now surprisingly been fulfilled by the present invention, which relates to an emulsion ointment composition, containing from 0.5% by weight of at least one local anesthetic and which is characterized in that the local anesthetic in base form as such or dissolved in an oil forms the oil phase of an oil-in-water emulsion, wherein the concentration of local anesthetic in the oil droplets is such that the oil is substantially saturated with said local anesthetic and that the majority of the oil droplets have a size not exceeding 10 μ, preferably not exceeding 3 μm in diameter.
En ytterligare fördel med en sådan emulsionssalva är att den i vissa fall kan steriliseras medelst autoklavering.A further advantage of such an emulsion ointment is that in some cases it can be sterilized by autoclaving.
Enligt en föredragen utföringsform av uppfinningen är det lokalanestetiska medlet valt ur den grupp som består av prilokain, lidokain, bupivakain, mepivakain, etidokain, ketocain, 2-(2-n-butoxifenoxi)-l-diisopropylaminoetan, tetrakain, butanilikain, trimekain, dibukain, quinisokain, butakain, oxybuprokain och tolykain.According to a preferred embodiment of the invention, the local anesthetic is selected from the group consisting of prilocaine, lidocaine, bupivacaine, mepivacaine, ethidocaine, ketocaine, 2- (2-n-butoxyphenoxy) -1-diisopropylaminoethane, tetracaine, butanilicaine, trimeca , quinisocaine, butacaine, oxybuprocaine and tolykain.
Blandningar av lokalanestetiska medel kan också användas, varvid en av prilokain, tetrakain, butinilakain och trimekain blandas med en av lidokain, bupivakain, mepivakain, etido- kain, dibukain, tetrakain, butinilakain och trimekain.Mixtures of local anesthetics may also be used, one of which is prilocaine, tetracaine, butinilacaine and trimecaine mixed with one of lidocaine, bupivacaine, mepivacaine, ethidocaine, dibucaine, tetracaine, butinilacaine and trimecaine.
Andra blandningar kan också användas. ' l0 l5 20 25 30 7812020-1 Den framställda emulsionssalvan består av en emulsion av olja i vatten, varvid den förutom det lokalanestetiska medlet i basform omfattar vatten, ett lösningsmedel för det lokalanestetiska medlet om nödvändigt, och en emulgator och ett förtjockningsmedel.Other mixtures can also be used. 7812020-1 The emulsion ointment prepared consists of an emulsion of oil in water, in addition to the local anesthetic in basic form comprising water, a solvent for the local anesthetic if necessary, and an emulsifier and a thickener.
Företrädesvis omfattar formuleringen Lokalanestetiskt medel l-20 viktprocent Lösningsmedel (olja) 0-72 " Emulgator 0.2-20 " Förtjockningsmedel 0.5-2 " Vatten l5-95 " I vissa fall består det lokalanestetiska medlet av en olja av vilken följer 0 viktprocent av lösningsmedlet.Preferably the formulation Local anesthetic comprises 1-20% by weight Solvent (oil) 0-72 "Emulsifier 0.2-20" Thickener 0.5-2 "Water l5-95" In some cases the local anesthetic consists of an oil of which follows 0% by weight of the solvent.
Lösningsmedlet skall vara ett lösningsmedel som är oblandbart med vatten. Lämpliga lösningsmedel är monoglycerider som har en fettsyrakomponent med 12-18 kolatomer, exempelvis glycerylmonolaurat, och triglycerider, såsom exempelvis en härdad växtglyceridblandning, exempelvis Miglyol®8l2 olja, som är ett härdat kokosfett med medelkedjelängd.The solvent must be a solvent that is immiscible with water. Suitable solvents are monoglycerides having a fatty acid component having 12-18 carbon atoms, for example glyceryl monolaurate, and triglycerides, such as, for example, a hardened plant glyceride mixture, for example Miglyol® 822 oil, which is a medium chain hardened coconut fat.
Den använda emulgatorn är av non-jonisk typ såsom polyoxy- etylenfettsyra-ester eller sorbitan-fettsyra-ester. Sådana emulgatorer är Arlaton®289 och Tween®80. Lecitin kan också användas.The emulsifier used is of the non-ionic type such as polyoxyethylene fatty acid ester or sorbitan fatty acid ester. Such emulsifiers are Arlaton®289 and Tween®80. Lecithin can also be used.
Det använda förtjockningsmedlet kan också ha emulgerande egenskaper. Carbopol®, Methocel®, Pluronic® och karboxi- metylcellulosa kan användas. Carbopol® och Pluronic® har också emulgerande egenskaper.The thickener used may also have emulsifying properties. Carbopol®, Methocel®, Pluronic® and carboxymethylcellulose can be used. Carbopol® and Pluronic® also have emulsifying properties.
Tål 2020-1 lÜ 15 2D 30 35 Emulsionen framställes genom att lösa den lokalanestetiska basen i oljan (Miglyolfi8l2) och smältes tillsammans med emulgatorn (Arlaton@2B9], varvid en mindre mängd vatten tillsättes medan blandningen är varm. Den resulterande blandningen kyles, varpå Förtjockningsmedlet (Carbopolm) blandat med resten av vattnet tillsättes som en gel. Denna resulterande blandning homogeniseras till en sådan grad att huvuddelen av oljedropparna har en diameter av <3 p.Withstands 2020-1 lU 15 2D 30 35 The emulsion is prepared by dissolving the local anesthetic base in the oil (Miglyol fi8 l2) and melted together with the emulsifier (Arlaton® 2B9], adding a small amount of water while the mixture is hot. The resulting mixture is cooled, then cooled. The thickener (Carbopolm) mixed with the rest of the water is added as a gel, this resulting mixture is homogenized to such an extent that the majority of the oil droplets have a diameter of <3 p.
Det lokalanestetiska medlet löses i oljan på sådant sätt att en mättad lösning, eller huvudsakligen mättad lösning av anestetiskt medel i oljan erhålles. Med användning av lidokain erhålles mättnad, då 27.6 % lidokainbas har lästs.The local anesthetic is dissolved in the oil in such a way that a saturated solution, or substantially saturated solution of anesthetic in the oil is obtained. With the use of lidocaine, saturation is obtained, as 27.6% lidocaine base has been read.
Enligt uppfinningen skall oljedropparna inte överstiga en diameter av 1D p, företrädesvis inte 3 p. Emellertid skall inte oljedropparna homogeniseras i sådan grad att en mikro- emulsion erhålles, då denna kommer att Förlora sin aktivitet.According to the invention, the oil droplets should not exceed a diameter of 1D p, preferably not 3 p. However, the oil droplets should not be homogenized to such an extent that a microemulsion is obtained, as this will lose its activity.
Dosen lokalanestetiskt medel beror på medlets potens men är som regel l-3DD mg/omz, mera vanligt 5-3D mg/omz.The dose of local anesthetic depends on the potency of the agent but is usually 1-3DD mg / omz, more usually 5-3D mg / omz.

BIÜLÛGISK EFFEKT Material och metoder Marsvin (hanar, Dunkin-Hartley-stam), 6-8 veckor gamla, användes i denna studie. Håret på huden på ryggen hos mar- esvinen avlägsnades och en cirkelFormad yta av ungetär 4.5Cm2 skrapades med BUF-Putm (Riker). Testberedníngen gnuggades in i det skrubbade skinnet under 30 sekunder. Test tör anestetisk eftekt medelst prickning med nål utfördes sex gånger på olika platser på det behandlade området med regel- bundna intervall under och eFter tidpunkten ¥ör applicering intill dess att ingen anestetisk eF¥ekt kunde registreras.BIOLOGICAL EFFECT Materials and methods Guinea pigs (males, Dunkin-Hartley strain), 6-8 weeks old, were used in this study. The hair on the skin on the back of the guinea pig was removed and a circle-shaped surface of 4.5 cm2 was scraped with BUF-Putm (Riker). The test preparation was rubbed into the scrubbed skin for 30 seconds. Testing for anesthetic effect by needle puncture was performed six times at different sites on the treated area at regular intervals during and after the time before application until no anesthetic effect could be registered.
Testberedningen tvättades inte bort.The test preparation was not washed off.
Emulsionssalvor med 0.25-5.0 % lídokain och 5.0 % lidokain- salva studerades. De använda beredningarna är beskrivna i tabell l. Studien genomfördes dubbelblint. Student's t-test användes För att beräkna den statistiska signifikansen. En signiFikant skillnad hade ett P-värde av:í0.05.Emulsion ointments with 0.25-5.0% lidocaine and 5.0% lidocaine ointment were studied. The preparations used are described in Table 1. The study was conducted double-blind. Student's t-test was used to calculate the statistical significance. A significant difference had a P-value of: í0.05.
