Question

Quizplus · Accepted Answer

β₁ agonists are typically used to treat conditions such as asthma and bronchospasm, and thus they cause bronchodilation. However, they also activate β1-adrenergic receptors which can cause an increase in blood pressure and heart rate (tachycardia). Constipation is a common effect of these drugs due to their actions on smooth muscle cells in the gastrointestinal tract. Option A is incorrect because these drugs typically cause an increase in blood pressure and cardiac workload, not a decrease. Option B is incorrect because it incorrectly states that these drugs cause increased vasoconstriction, when in fact they cause vasodilation in some vascular beds. Pupil dilation is also not a common effect of β₁ agonists. Option D is incorrect because although tremor is a common effect of these drugs, bronchodilation and tachycardia are the more consistent effects.
