Theophylline pharmacokinetics before and after rifampicin administration was studied in 10 healthy volunteers. It was seen that Rifampicin significantly increased the volume of distribution of theophylline by 23.41% (p < 0.01) and its metabolic clearance by 47.65% (P < 0.05). This has got clinical significance in the treatment of patients of pulmonary tuberculosis with chronic obstructive airways disease where both the drugs may have to be given concurrently.
