Comparison of intravenous and aerosol salbutamolAerosol salbutamol has a prolonged bronchodilator effect' and is more potent than an equal intravenous dose.2We have studied both routes of administration in asthmatic patients to compare their length of action. Patients, methods, and resultsFive patients with well controlled asthma were studied.Their asthma showed no significant diurnal variation.All were being treated with salbu- tamol by regular inhalation, and three took prednisone.They were studied on two consecutive mornings, having stopped bronchodilator drugs for 12 hours. CommentThese results indicate that routine heparin treatment during standard haemodialysis three times a week caused no significant acute change in the SGPT activity.Moreover, the range of SGPT values was not significantly different from that of the normal population, suggesting that chronic, intermittent heparin treatment does not cause on 4 July 2023 by guest.
