Patients who are suffering from chronic inflammatory lung diseases such as asthma or COPD may be treated with medication targeted to induce more smooth muscle relaxation in the lungs and less contraction of the heart, including first-generation drugs like salbutamol (albuterol) and later-generation medications in the same class.
Salbutamol, also known as albuterol and sold under the brand name Ventolin among others, [1] is a medication that opens up the medium and large airways in the lungs. [8] It is a short-acting β 2 adrenergic receptor agonist that causes relaxation of airway smooth muscle . [ 8 ]
Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. [1] The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine ), which function as both neurotransmitters and hormones .
An FDA-approved medication already used to treat people who have type 2 diabetes and chronic kidney disease may also help lower their stroke and heart attack risk, a new study has found.
The precise function of these receptors has not been established. However, all β adrenergic agonist drugs can produce a significant cardiovascular effect in some patients, as measured by pulse rate, blood pressure, and restlessness symptoms, and/or electrocardiographic (ECG).
More severe effects, such as pulmonary edema, myocardial ischemia, and cardiac arrhythmia, are exceptional.) [6] [7] [1] Overuse of β 2 agonists and asthma treatment without proper inhaled corticosteroid use has been associated with an increased risk of asthma exacerbations and asthma-related hospitalizations.

β2-agonist e.g. albuterol because it may increase the efficacy of albuterol on the cardiovascular system. Medicines that affect norepinephrine (e.g. venlafaxine, imipramine, mirtazapine) should be used with caution when administered with atomoxetine due to possible synergy or synergistic effects on pharmacodynamic effects.
The suppression of contractions is often only partial and tocolytics can only be relied on to delay birth for a matter of days. Depending on the tocolytic used, the pregnant woman or fetus may require monitoring (e.g., blood pressure monitoring when nifedipine is used as it reduces blood pressure; cardiotocography to assess fetal well-being ...
