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.

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.
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 .
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 ]
The term "steroid dementia" was coined by Varney et al. (1984) in reference to the effects of long-term glucocorticoid use in 1,500 patients. [3] While the condition generally falls under the classification of Cushing's syndrome , the term "steroid dementia syndrome" is particularly useful because it recognizes both the cause of the syndrome ...
Many tricyclic antidepressants, tetracyclic antidepressants, antipsychotics, ergolines, and some piperazines like buspirone, trazodone, nefazodone, etoperidone, and mepiprazole antagonize α 1-adrenergic receptors as well, which contributes to their side effects such as orthostatic hypotension.
However, in clinical trials, high blood pressure was reported in just one percent of patients taking 2.5-milligram tadalafil and three percent of patients taking the 5-milligram dose.
In the mid-1960s, albuterol or salbutamol was discovered, followed by tributalin and fenoterol a few years later. Albuterol and terbutaline gave fewer side effects, such as increased heart rate, than isoproterenol. The pharmaceutical company Glaxo discovered salmeterol, a long-acting β 2-agonist that had bronchodilation activity for up to 12 ...
