The bronchodilating effect of two doses of peroral enprofylline was compared with placebo in 24 asthmatic patients. Enprofylline produced significantly greater bronchodilatation than placebo. A dose of 2 mg/kg b.wt. and 4 mg/kg b.wt. caused a mean maximal increase in FEV1 of 26% and 35%, respectively. The degree and the incidence of headache and nausea were estimated by means of a scoring system. Dose-related effects on both parameters were observed. Other side effects were negligible. In seven patients the mean plasma half-life of enprofylline was found to be 113 min. It is suggested that enprofylline should be studied further in patients suffering from obstructive lung disease.
