Pharmaceutical compositions and methods for producing alpha.sub.2 antagonism utilize, as active ingredients, 6-halo-N-substituted 2,3,4,5-tetrahydro-1H-3-benzazepines. These compositions are particularly useful for lowering intraocular pressure and for the treatment of abnormal cardiovascular conditions such as, for example, congestive heart failure, angina pectoris and thrombosis. The compositions and compounds of this invention, also, produce a reduction in blood pressure in hypertensive subjects and are, therefore, useful as antihypertensive agents.
