Abstract

Following epidermal application of 5 g Dolo-Arthrosenex ointment for gel, respectively, containing 625 mg ethyleneglycol salicylate (corresponding to 473.9 mg salicylic acid) upon a skin area of 100 cm2 of 12 normal volunteers transdermal absorption of salicylate was measured over a period of 48 h after application by means of renal salicylate excretion. A high-pressure liquid chromatography method was employed for the quantitative estimation of urinary levels of salicylic acid and salicyluric acid. Afer application of the ointment in the mean 26.7% of the applied salicylate dose is resorbed within 24 h and excreted within 48 h, respectively. From the gel in the mean 48.0% of the applied salicylate dose is absorbed within 24 h and excreted within 48 h, respectively.
