Definition
- Vasoconstriction à Increase BP, keeps blood at vital organsàalpha 1
- Cardiac Stimulation à Increase HR, stimulates heart to work, increases force of contraction
- Bronchodilation à Increase oxygen ventilation à Beta 2
- Glycogenolysis à breaks down glycogen from liver to glucose – diabetics must be carefully monitored

Term
|
Definition
| Anaphylaxis Hypotension à shock Nasal Congestion Dilated Pupils à vision problems are cues to cardio problems Relax Bronchi |
|
|
Term
Adrenergic Adverse Effects? |
|
Definition
| Hypertension Tachycardia – expected affect Reflex bradycardia à adverse reaction Increase blood glucose Necrosis with extravasation à tissue damage/death |
|
|
Term
|
Definition
| Cardiac Depression Peripheral vasodilation Some smooth muscle relaxation (GI, Bladder) Bronchial constriction |
|
|
Term
Antiadrenergic Clinical uses? |
|
Definition
| Hypertension Dsyrhythmias Heart Failure – pump mechanism Angina (relax of blood vessels) Benign prostatic hypertrophy |
|
|
Term
Antiadrenergic Adverse Effects? |
|
Definition
| Dysrhthmias Heart Failure Reflex tachycardia Orthostatic hypotension – “1st dose syncope” – fainting |
|
|
Term
|
Definition
- Nicotinic: skeletal muscle – contractions; enhanced transmission of impulses
- Muscarinic : Heart rate, blood vessels, BP – slows HR, vasodilation, BP changes
- Respiratory and GI secretions – increase resp. and GI secretions Pupils constrict
- Smooth muscle tone in GI tract, bladder, and bronchi – side effect = diarrhea
- GU and GI sphincters – relax

Term
Cholinergic Clinical uses? |
|
Definition
| Diagnose and treat myasthenia gravis (MG) – can cause respiratory failure Reverse neuromuscular blockade Treat urinary retention Relieve postoperative abdominal distention Treat Alzheimer's disease (AD) |
|
|
Term
Cholinergic Adverse Effects? |
|
Definition
| Bronchospasm Cardiac dysrhythmias, Hypotension GI distress Sweating Convulsions |
|
|
Term
|
Definition
- CNS –stimulation and then depression
- Decreased Muscle tone in GI tract, bladder, and bronchi
- Decrease in Respiratory and GI secretions
- Increased Urinary sphincter tone
- Increased Heart rat
- Pupil dilation

Term
Anticholinergic Adverse effects? |
|
Definition
| Blurred vision, increase in IOP (intra ocular pressure) à don’t give to pt’s with glaucoma Constipation Dry mouth Pee à Urinary retention Tachycardia – increased HR BCDPT |
|
|
Term
|
Definition
| CNS –stimulation and then depression Muscle tone in GI tract, bladder, and bronchi – decreased Urinary sphincter tone –increased Heart rate -increased Respiratory and GI secretions – decreased Pupils –dilation |
|
|
Term
Anticholinergic Clinical uses? |
|
Definition
| Asthma – opens airways, decreased secretions (controversial use) Overactive bladder Treat or prevent bradycardia , heart block Decrease resp/gi secretions in surgery Treat peptic ulcer disease – decrease in GI secretions à acid, bile, enzymes help reduce trauma Dilate pupil for exam, surgery – optometrist |
