Introduction to Human Anatomy Lecture 23 Notes: Autonomic Drugs 1


Today we have a 40 minute lecture, part 1 of 4, on drugs affecting the autonomic nervous system.  This ought to be an interesting mini-series.


The autonomic nervous system is the “rest and digest system.”

Parasymphatomimetic Drugs – muscarinic cholinergic agonists.  Mimics the effects of parasympathetic molecules on the body.  Agonists active.  Giving acetylcholine directly would have too short of an action time.

epinephrine is adrenalin.

Direct Acting Cholinergic Agonists

Prototype – evosac

pharmacodynamics activates all of the muscocarinic ACl receptor sites.

Pharmacokinetics is what the drug does to the body.

Clinical uses

Used to increase salivation for treatment of xerostomia or sjorgren’s syndrome.

Used to increase G motility to post operation atomy after general anesthesia

Used to increase emptying of the urinary bladder in the urinary bladder.

Decrease intra-ocular pressure in glaucoma.  During times of stress, the pressure in the eye increases.  Chronic increase is glaucoma.

Contraindication is a warning.  Don’t use if you have asthma.  This drug increases the parasympathetic response.  Broncoconstriction is also caused.

Warnings or Cautions are for effects on the entire body.  The drug slows the heart rate.

Can cause headaches, generalized vasociatation or bodily flushing, salivation, hypertension, abdominal cramps with diarrhea, sweating.  bradycardia slowing of the heart rate.

Miosis and cycloplegia – pupilary constriction and eye paralysis on near vision

Cautions – use the drug but you’ll see these sides

Contraindication – don’t use it

Blockage of GIT, rupture or intestine.  Obstruction of the urinary tract.  Ulcers, asthma, heart problems.

Parasympathlytic Drugs

Block ACh sites

belladonna alkaloids

Prototype: atropine sulfate, tropine

Decrease secretions, decreased salivation, dry air passages,

prior to surgery, during surgery and after surgery

colds hayfever

eye examps

increase heart rate

controlling aurethis or bed wetting

produce sedation

motion sickness

irritable bowel syndrome IBS


action terminated by renal excretion

dry as a bone, hot as a hare, red as a beet, blind as a bat

Block the parasympathetic into stress mode

Atrovant for asthma

block the parasympathetic, dilate airways.
