A drug lacking vasodilatory propeies that is effective in angina is:
Isosorbide dinitrate (IDN)
Metoprolol
Nifedipine
Verapamil
Beta blockers act in angina by decreasing exercise induced myocardial work by reducing HR. These do not cause vasodilation. Nitrates (IDN) and CCBs (Nifedipine, Verapamil) act by causing vasodilation.
