Adrenergic Drugs
Term | Definition |
---|---|
The body's nervous system is divided into 2 major branches | CNS and PNS |
The CNS contains | The brain and spinal cord |
The PNS is subdivided into | Somatic and autonomic nervous systems |
the autonomic is subdivided into | parasympathetic (cholinergic) and sympathetic (adrenergic) |
Adrenergic compounds include | exogenous (synthetic) and endogenous (produced naturally in body) substances. They have a wide variety of therapeutic uses dependent on site of action and effect on adrenergic receptors. |
The 3 endogenous SNS neurotransmitters are | norepinephrine, epinephrine, dopamine |
chemically classified as catecholamines (produced naturally in body) | norepinephrine, epinephrine, dopamine |
exogenous catecholamine (synthetic) | dobutamine |
At these receptors, adrenergic drugs bind and produce effects | ADRENERGIC RECEPTORS |
receptor sites for the catecholamines norepinephrine and epinephrine throughout the body are referred to as | adrenergic receptors |
The beta-adrenergic receptors are all located | on postsynaptic effector cells |
