Pharmacology Year 1 Lvl 2 Flashcards
Adrenergic Agents (sympathomimetic)
Meds that mimic NE, cause they mimic axn produced by SNS.
Adrenergic Blocking Agents
inhibit or reduce SNS activity adrenergic activity. (eg. beta blockers “olol”)
Cholinergic Agents (Parasympathomimetics)
Meds that mimic ACH, cause they mimic axns produced by PNS.
Gabapentine
Helps with nerve pain (neuralgia, or shingles)
Anticholinergic drugs
drugs block or inhibit cholinergic axns (block PNS axns)
Classification of sleep pattern disturbances
Transient (lasting a few nights) Short Term (less than three weeks, travel/ anxiety) Chronic (longer than 1 month)
Insomnia (3 types)
Initial: inability to fall asleep
Intermittent: inability to stay asleep
Terminal: early awakening but inability to fall asleep again
Sedatives
Drug that calms and gives feelings of rest and relaxation, not necessarily accompanied by sleep. eg. ativan
Hypnotic
Produces sleep, normal awakening, no hangover effect, no danger of habit formation.
Barbiturates
Axn: Cause CNS depression which is reversible. Sedative and Hypnotic effects. Often used for seizure disorders. eg. phenobarbital
Benzodiazepines
CNS depressant but more site specific, hypnotic and sedative effect. Think “zzz” eg. ativan
Examples of Non Barbiturate, Non Benzodiazepines Sedative/Hypnotic agents
Melatonin, Benadryl, Dimenhydrinate (Gravol), Diphenhydramine (Benadryl)
Parkinson’s Medication Function
Drugs that aim to replace or block destruction of dopamine.
Selegiline & Rasagiline
Causes neuroprotective factors that interfere with the degeneration of dopaminergic neurons
Monoamine Oxidase Inhibitors
Blocks destruction of monoamines serotonin, dopamine, and NE to prolong their effect
Helpful for depression and parkinson’s
Antiparkinsonians
AXN: drug crosses blood brain barrier and metabolizes into dopamine increasing the levels in the brain.
Levadopa and Sinemet (Levadopa & Carbidopa)
Dopamine Agonists (Apomorphine)
AXN: dopamine agonists slow destruction of dopamine and aids in release of of dopamine from its storage site
Do not administer IV
Anticholinergic Agent
Realigns the balance between dopamine and ACH, and decreases ACH in the brain.
Will reduce drooling, and tremors. Slowing PNS so be mindful of side effects could occur, eg. constipation.
Alzheimer’s Agents (Cholinesterase inhibitors)
AXN: Blocks the breakdown of the NT ACH. (Slows progression of ACH destruction. Memory, learning and thinking)
eg. Aricept
Serotonin
NT that helps regulate memory and learning, associated with feelings of happiness, and relaxation.
Melatonin
Is a hormone that is secreted by the pineal gland that helps to regulate sleep schedule and circadian rhythm.
Selective Serotonin Reuptake inhibitor (SSRI)
AXN: decreases the breakdown of serotonin at the synaptic cleft to allow more serotonin available for the neurons.
Serotonin Syndrome
Toxicity of serotonin
S&S: irritability, increased muscle tones, shivering, seizures, myoclonus, tachycardia, reduced consciousness.
Tricyclic Antidepressants
AXN: prolong the axn of NE, dopamine, and serotonin to varying degrees by blocking the reuptake of these NT in the synaptic cleft between neurons. eg . amitriptyline
Miscellaneous Agents - Wellbutrin HCL
Prolongs the axn of NE, dopamine, and serotonin by blocking reuptake (less than tricyclics)
Diuretic
Causes the body to ride itself of excess fluids and sodium through urination
3 types of Diuretics and drugs names
- Loop Diuretic (Furosimide)
- Potassium Sparing Diuretic (Spironolactone)
- Thiazide/ Thiazide - like agents (Hydrochlorothiazide)
Loop Diuretic
Furosemide (Lasix)
Potassium Sparing Diuretic
Spironolactone (Aldactone)
Thiazide/ Thiazide - like agents
Hydrochlorothiazide (Esidrix, Hydrodiuril)
ACE Inhibitors
Expands blood vessels and decreases resistance by lowering levels of angiotensin II. Allows blood to flow more easily and makes the heart’s work easier or more efficient.
“Prils”
Common ones, Benzapril (Lotensin), Ramipril (Altace)
Beta Adrenergic blocking agents
“Beat Blockers” "lol" Decrease HR and cardiac OP, which lowers blood pressure and makes the heart beat more slowly with less force. Atenolol (Tenormin) Metoprolol (Lopressor, Toprol XL) Propranolol (Inderal)
Drug Classes that can be used for Hypertension ABCD?
Diuretics
Beta blockers
ACE inhibitors
Calcium channel blockers
Drugs used for Heart Failure
Vasodilators Inotropic agents Diuretics ACE inhibitors Beta blockers Calcium channel blockers
Most common drug used for HF
Digitalis Glycosides: Digoxin/ Lanoxin
Digitalis Glycosides
Increases the cardiac contractility and slows heart rate.
What must nurses always do before administering Digoxin?
Take apical pulse for one minute and ensure HR is more that 60bpm.
Digitalis Toxicity
Build up of digoxin in body.
S&S
Blurred vision
Anorexia
N&V
Dysrhythmias
a disturbance in the normal conduction of the heart causing abnormal contraction or HR.
Antiarrhythmic Drugs (Common)
Quinidine is the most common class one drug for dysrhythmias
Class 2 beta blockers
Class 4 Calcium Channel Blockers (Diltiazem, Verapamil)
Digitalis Glycoside
Serum Electrolytes
Potassium
Sodium
Chloride
Bicarbonate
Drugs used to treat Angina Pectoris
Nitrates (FOCUS ON THIS PRIMARILY)
Calcium channel blocker
Beta Blocker
Hyperlipidemia
Elevated levels of cholesterol and triglycerides in the blood that can lead to atherosclerosis
Medication Routes
Oral Transdermal Suppository Intramuscular Subcutaneous Buccal Ophthalmic/ intraocular Enteral (GI tract, oral, rectal) Percutaneous (through skin, occular, patch, inhaler, buccal) Parenteral (Bypass GI, IV, IM, Subq, NEEDLES)
