what are adrenergic agents
|
Adrenergics are a large group of both exogenous (synthetic) and endogenous (naturally occurring) substances.
Stimulate the sympathetic nervous system Called adrenergic agonist or sympathomimetics Mimic the effects of the SNS neurotransmitters norepinephrine and epinephrine (catecholamines) |
|

|
|
what are endogenours adrenergic drugs
|

|
what are beta 1 adrenergic receptors
|
adrenergic receptors are on the myocardium and in the conduction system of the heart, the SA node, and the AV node. When the Beta 1-adrenergic receptors are stimulated by an adrenergic drug, and increased force of contraction (positive
|
|
|
what are beta2 adrenergic receptors
|
produces relaxation of the bonchi (bronchodilation) and uterus, stimulate glycogenolysis and increase renin secretion I
|
|
|
what are respiratory indications
|
2 –adrenergic receptors affect the bronchial, uterine, and vascular smooth muscles
Some common bronchial dilators are: albuterol, bitolterol, ephedrine, epinephrine, isoproterenol, levalbuterol, terbutaline. beta 2 are usuful in asthama and bronchitis |
|
|
what are nasal decongestants indications
|
affect alpha1-adrenergic receptors
|
|
|
what are ophthalmic indications
|
work on the vasculature of the eyes and stimulate alpha-adrenergic receptors located on small arterioles in the eye. Reduce ocular pressure
|
|
|
what are the side effects of adrenergic drugs
|
CNS effects of alpha-adrenergic agents are headache, restlessness, excitement, insomnia, euphoria, hypertension, tachycardia, and palpitations, or dysrhythmias.
Beta-adrenergic agents cause tremors, headache, nervousness, and dizziness, palpitations, sweating, nausea, vomiting, and muscle cramps Toxic effects are seizures, hypertension, stroke |
