title: Combined therapy with ipratropium and theophylline in asthma.
abstract: Ipratropium (40 micrograms) and theophylline (oxtriphylline 400 mg) were administered to 24 asthmatics in a randomized double-blind placebo controlled trial. The combination of these agents produced additive bronchodilation for up to two hours, with a 23 percent maximal increase in FEV1. This regimen promises to be safe, effective therapy for patients with asthma.
