Abstract:
A method for making a medication for use in ophthalmology, comprising dissolving an ophthalmologic medicament in a semi-fluorinated alkane of the general formulaR.sub.F R.sub.H or R.sub.F R.sub.H R.sub.Fwherein R.sub.F is a linear or branched perfluoralkyl group and R.sub.H is a linear or branched, saturated alkyl group, wherein the linear semifluorinated alkane has the formula:F(CF.sub.2).sub.n (CH.sub.2).sub.m H orF(CF.sub.2).sub.n (CH.sub.2).sub.m (CF.sub.2).sub.n F,the branched semifluorinated alkane includes within the perfluoralkyl groups --FCX-- units where X=C.sub.2 F.sub.5, C.sub.3 F.sub.7 or C.sub.4 F.sub.9 and within the alkyl groups --HCY-- units where Y=C.sub.2 H.sub.5, C.sub.3 H.sub.7 or C.sub.4 H.sub.9, contained within a perfluoralkyl chain is a --CX.sub.2 -- group and contained within an alkyl chain is a --CY.sub.2 -- group, and wherein further the total number of the carbon atoms in the perfluoralkyl part are between 3 and 20, and in the alkyl part the number of the carbon atoms is between 3 and 20.
