Terbutaline & Salbutamol
(bronchodlators. Saibutamol also used to today labour)
Agonists
Antagonists
Propranolol
(treats tachycardia)
Iso prenaline
(treats bradyc ardia , astham. contra-indicated for my ocardial ischemia)
adrena line
(increases HR, constrcts blood vessels, diates air pas sages.
actions vary by tissue type and expression of adrenergic rece ptors.
Sympathomimetcs = adrenergc agonists
sympathomimetcs=adrenergc a nta gonists
a receptors are in blood v essels, cause contraction, the refore increas e BP
B1 rec eptors are in heart: increase HR, CO
B2 rec eptors cause smooth muscle re laxation (bladder, bronchi, uterus)

Pilocarp ine
(used to treat glaucoma via M3)
Met hacho line
(diagnose asthma, causes bronchoconstr iction)
Bethanecol
(b ladder contraction, trats urinary retention via M3)
Atropine (treats muschroom poisoning , prevents bronchoconstr iction)
Hyoscine (anti- emetic . Motons ickness)
piren zepine (M1 , inhibits gastric acid sec retion - trests uicers)
Benztro pine ( anti - parkinson ian dyskinesia)
Ipratropium (bronchodillation - treats as thma)
Carbach ol (treat glaucome)
Su xametho nium
(depolar ising blocker - muscle relax ant .
Is a partial agonist- prevents further
depoler is ation so has antagon is tic effects)

Muscarinic AChR found in receptors
of Parasympathic Innervatiion
(exception - MACHR in Sweat
glands are sympathetic
M1 - neural & GI motility - excitation
M2 - Cardiac Inhbtion - Inhibition
M3 - glandular secretions and
vasodlation via No - excitation
Nicotonic AChR found
in Skeletal muscle and
all postgang fonic
neurone in ANS
AChE Inhibitors are indirect
chollnergic agonists - they
increase the effects of ACh
at the re Ceptor. Mainly M

This ANS drugs concept map nursing depicts autonomic drugs that can inhibit or enhance the parasympathetic and sympathetic nervous systems' functions. This type of medication can treat various conditions, including glaucoma, asthma, urinary, gastrointestinal, and cardiopulmonary disorders. Activating the parasympathetic nervous system can result in significant physiological effects such as an increase in the glandular secretion, an increase in smooth muscle contraction, and a decrease in both heart contractility and heart rate. Neurotransmission involves two types of nicotinic receptors and muscarinic receptors to achieve the aforementioned physiological effects. These two receptor groups can bind to the same neurotransmitter, acetylcholine, to relay neurotransmission in the synapse.
