Autonomic nervous system drugs Flashcards
Autonomic drugs purpose
They are used clinically to either imitate or inhibit the normal functions of the sympathetic and parasympathetic nervous systems.
Central nervous system
👉Brain
👉Spinal cord
Peripheral nervous system
👉Nerve
👉Ganglion
what controls involuntary responses?
Autonomic nervous system
3 key components to the ANS
Two of which are of primary concern in
this discussion: the sympathetic nervous system
(SNS) and the parasympathetic nervous system
(PNS). The third component, the enteric nervous
system (ENS).
What are the autonomic drugs?
They are used clinically to either imitate or inhibit the normal functions of the sympathetic and parasympathetic nervous systems.
What happens if the ANS is damaged?
It can affect blood pressure, temperature control, digestion, bladder function and even sexual function.
Acetylcholinesterase
Enzyme responsible for the degradation of Ach.
Nonselective α-Adrenergic Blockers
Medications that block α1- and α2-adrenergic sites.
Nonselective β-Blockers
Medications that block β1- and β2-adrenergic sites.
Selective α-Adrenergic Blockers
Medications that block α1-adrenergic sites only.
Selective β-Adrenergic Blockers
Medications that block β1-adrenergic sites only.
How long does it take the nervous system to heal?
Most people improve within three to six months, but surgery may be needed based on the lack of clinical improvement and other tests, including an ultrasound and electromyography.
Can stress cause autonomic
Chronic real-life stress in humans appears associated to increased arterial pressure and to impaired autonomic regulation of cardiovascular functions.
What is the best vitamin for nervous system
Neurotropic B vitamins play crucial roles as coenzymes and beyond in the nervous system. Particularly vitamin B1 (thiamine), B6 (pyridoxine), and B12 (cobalamin) contribute essentially to the maintenance of a healthy nervous system.
Vitamin B12
Enhances Nerve Repair and Improves Functional Recovery After Traumatic Brain Injury by Inhibiting ER Stress-Induced Neuron Injury.
When the sympathetic system is not functioning correctly or the body is in a state of homeostatic imbalance, these drugs act at postganglionic terminals and synapses in the sympathetic efferent pathway
Sympathomimetic Drugs
Phenylephrine
Common sympathomimetic drugs
that is a common component of decongestants. It can also be used to dilate the pupil and to raise blood pressure.
Sympatholytic Drugs
Drugs that interfere with sympathetic function are referred to as sympatholytic, or sympathoplegic, drugs
β-blockers
These drugs are often used to treat cardiovascular disease because they block the β-receptors associated with vasoconstriction and cardioacceleration. By allowing blood vessels to dilate, or keeping heart rate from increasing, these drugs can improve cardiac function in a compromised system, such as for a person with congestive heart failure or who has previously suffered a heart attack
