Abstract:
To investigate the safety and efficacy of Adenoscan injection 60 mg (adenosine), a pharmacologic stress agent that can be used for coronary vasodilation in patients unable to exercise adequately, the drug use results survey was conducted by consecutive patients-survey method in 166 nationwide medical institutes from 2006 to 2008. Adverse drug reactions (ADRs) occurred at the rate of 16.0% (343/2,150 patients), most of which disappeared shortly with no need for treatment. Major ADRs were chest discomfort at the rate of 4.9%, chest pain 2.0%, atrioventricular block 1.8% and dyspnea 1.4%. There were no differences in the incidences of ADRs between the elderly and the non-elderly. The overall efficacy rate was 97.9% (2,104/2,150 patients) according to the efficacy judgment of each primary physician. The sensitivity, specificity and diagnostic accuracy of myocardial perfusion scintigraphy in 608 patients who underwent coronary angiography were 70.8%, 58.1% and 65.0%, respectively. We conclude that adenosine stress is safe and useful for myocardial perfusion scintigraphy to detect ischemic heart disease for patients who are unable to exercise adequately.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Adrenergic Agonists: Therapeutic Classification
Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).
Bronchodilators: β2-agonists can relax bronchial muscles and widen airways. They are commonly used for treating obstructive pulmonary...
Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
Adrenergic Antagonists: Pharmacological Actions of ɑ-Receptor Blockers
α1-blockers: These drugs inhibit α1-adrenoceptors on smooth muscle cells, resulting in vasodilation. This vasodilation lowers blood pressure, making α1-blockers valuable in treating hypertension. Additionally, α1-blockers effectively address urinary obstruction...
