Hospital study of transferable drug resistance.

Verapamil in Angina-PhearBuD m 741 reduction of glyceryl trinitrate intake on verapamil was 16.1 tablets a week, suggesting that glyceryl trinitrate was used rather arbitrarily and not only for angina.Neither trial corresponds to the ordinary conditions of ambulant treatment. Summary and ConclusionsA double-blind trial is reported of verapamil in 20 outpatients with angina.The dose of verapamil was 80 mg.three times daily for a fortnight, with a similar period on placebo tablets.No significant relief of angina by verapamil was found.I am grateful to Dr. F. J. A. Bateman, of Pfizer Ltd., for supplies of verapamil (Cordilox) and control tablets.
