Abstract
The penetration of prednisolone acetate (1%) and fluorometholone alcohol (0.1%) into human aqueous humour following topical application was determined using the very sensitive and specific technique of Gas Chromatography with Mass Spectrometry (GCMS). Prednisolone acetate afforded peak mean concentrations of 669.9 ng/ml within two hours and levels of 28.6 ng/ml in aqueous humour were detected almost 24 hours post application. The peak aqueous humour level of fluorometholone was 5.1ng/ml. The results are compared and contrasted with the absorption of dexamethasone alcohol (0.1%), betamethasone sodium phosphate (0.1%) and prednisolone sodium phosphate (0.5%) into human aqueous humour.
