Selected Rofams as a micellar solubilizers for diclofenac and naproxen in the environment of the standard vehicle for eye drops.
The process of the equilibrium solubilization of nonsteroidal anti-inflammatory drugs (NSAID), viz. diclofenac and naproxen, by Rofams, ie. the products of the oxyethylenating of the rape oil fatty acid methyl esters, in the environment of water solutions NaCl 9 g/l, H3BO3 19 g/l, KNO3 16 g/l, was tested. The solubilization activity of Rofam aqueous solutions was estimated with the use of the spectrophotometric method by means of the determination of the amount of the solubilized NSAID. The calculated apparent solubility of Rofam aqueous solutions was the basis for the estimation of the micellar partition coefficient K(w)m. The course of the ratio of the solubilized naproxen and diclofenac in the function of the solubilizer (Rofam R-13, R-15, R-17) exposure concentration was described by means of approximative equations with a high correlation coefficient.
