Summary The influence of ponsinomycin on the pharmacokinetics of theophylline has been studied in 12 young healthy volunteers. They received 10 doses of theophylline 200 mg every 8 h p.o., successively in the absence and then in the presence of ponsinomycin. This new macrolide, structurally related to midecamycin, was given in the therapeutic dose of 800 mg b.d. for 5 days, starting 2 days before the second phase of treatment with theophylline. The pharmacokinetic parameters of theophylline, calculated from its plasma concentration at steady-state, were not affected by the co-treatment. In particular, there was no significant difference between the peak and trough plasma levels, apparent clearance or apparent elimination half-life of theophylline in the absence and the presence of ponsinomycin. Only renal clearance was slightly (27%) but significantly increased by the co-treatment. The results suggest that ponsinomycin would be a good choice if a macrolide antibiotic were needed in patients being treated with theophylline.
