Which lipid profile changes are associated with the use of nonselective β blockers?

Why are cardioselective β blockers preferred in treating asthma patients who use insulin?

True or False: There are clinically useful β2 antagonists available for use.

True or False: β blockers induce postural hypotension due to the blockade of α adrenoceptors.

True or False: Propranolol primarily blocks β1 receptors and has no effect on β2 receptors.

Nebivolol has no vasodilator properties mediated by nitric oxide.

Coldness of extremities is less frequent in patients treated with cardioselective β blockers.

Pindolol and acebutolol are pure antagonists with no intrinsic sympathomimetic activity (ISA).

Blocking β2 receptors leads to vasodilation.

Propranolol, when given at therapeutic doses, has a significant membrane-stabilizing effect on the heart.

Patients with hypertension may experience a gradual reduction in both systolic and diastolic blood pressures with long-term use of propranolol.

β blockers generally have a significant effect against ventricular arrhythmias, especially those induced by exercise.
