ABSTRACT
An open two weeks short term trial of Ipratropium Bromide (IB) inhalation (0.02 mg per dose) was carried out in 20 stable asthamatics to study its efficacy and safety. Early significant rise in PEFR (P < 0.001) and FEV1 (P < 0.05) was observed after 15 min of IB inhalation and reached significant peak (P < 0.01) after 1 hour which was persistent beyond three hours after IB inhalation. No side effects were observed. It was concluded that Ipratropium Bromide Imhalation is safe and has efficient bronchodilatory effect on short term basis in stable asthmatics.

Double blind randomized trial of oral conventional and sustained release bronchodilators was undertaken to observe comparative efficacy in 30 patients older than 15 years. All cases selected were stable asthmatics at least for last 2 years having FEV1 improvement > or = 20%. Basal Pulmonary functions like FEV1, FVC and PEFR were recorded before and after drug administration at 1/2, 1, 2, 3, 4, 6, 8, 10, 12 and 24 hours. Four drug regimens were given as a single dose in the morning on randomized crossover manner on 1st, 4th, 7th and 10th days, sustained release theophylline 300 mg+salbutamol 4 mg (Drug I), salbutamol 4 mg + theophylline 300 mg (Drug II), salbutamol sustained released (asthalin SA) 8 mg (Drug III), salbutamol sustained released (ventorlin CR) 8 mg (Drug IV). Mean FEV1 changes observed at 0, 6 and 12 hours for all the drugs were compared which showed no statistical significance (t = 2.3876). Therefore, we conclude that using single dose fixed combination of oral salbutamol and aminophylline either in a plain or slow released form have no additive bronchodilator effect as compared to salbutamol alone in stable asthmatics.

Sixty seven patients with coexistent tuberculosis and hepatitis were given a 3 drug regimen of streptomycin (SM), isonicotinic acid hydrazide (INH) and ethambutol (ETB) and observed for a period of 15 days. Total bilirubin as well as SGPT were repeated weekly and these showed a significant drop in a majority of patients when observed over this period. No patient developed any signs of fulminant hepatic failure. We conclude that a regimen of SM, INH and ETB can be given to patients who suffer from combined pathologies of pulmonary tuberculosis and active hepatitis without incurring the danger of increasing hepatocellular dysfunction/damage.
