1

Actions

Acetylsalicylic Acid (Aspirin)

Irreversibly inactivates cyclooxygenase and blocks platelet aggregation, thus reducing propagation of clot in coronary vessels during MI. Blocks pain impulses in the CNS as a NSAID.

2

Actions

Adenosine (Adenocard)

Adenosine is a naturally occurring substance present in all cells that slows conduction through the AV node of the heart. Because of its rapid onset of action and short half-life, the administration of Adenosine is sometimes referred to as "chemical cardioversion".

3

Actions

Abuterol (Proventil)

A synthetic sympathomimetic that causes bronchodilation with reduced Beta 1 effects. Beta 2 adrenergic.

4

Actions

Amiodarone (Cardorone)

Prolongs phase 3 of the action potential, duration, and refractory period in myocardial cells; acts as noncompetitive inhibitor of alpha- and beta- adrenergic receptors. It also has sodium and potassium channel blocker actions.

5

Actions

Atropine Sulfate

* blocks acetylcholine receptors in organophosphate poisonings * reveres suspected vagal tone in bradycardia, asystole, and PEA

6

Actions

Calcium Chloride 10%

* increases myocardial contractile force and ventricular automaticity * balances hyperkalemia * aids in the re-entry of calcium into muscle when given for calcium channel blocker or magnesium sulfate toxicity

7

Actions

Dextrose 50%, 25%, 10%

increases blood glucose levels

8

Actions

Diazepam (Valium)

increases the inhibitory processes in the cerebral cortex

9

Actions

Diltiazem (Cardizem)

* inhibits the influx of calcium (Ca2+) ions during membrane depolarization of cardiac and vascular smooth muscle. The therapeutic benefits of diltiazem in SVTs are related to its ability to slow AV nodal conduction time and prolong AV nodal refractoriness. * decreases sinoatrial and atrioventricular conduction and has a negative inotropic effect.

10

Actions

Diphenhydramine HCL (Benadryl)

* block histamine receptor sites in allergic reactions. * reverses side effects of dystonic reactions caused by phenothiazines

11

Actions

Dopamine (Intropin)

  • @ 2-5 ug/kg/min, increases perfusion to kidneys and abdominal organs
  • @ 5-10 ug/kg/min, increases force and rate of ventricular contractions (Beta 1 effects)
  • @ 10-20 ug/kg/min, peripheral vasoconstrictor (alpha 1 effects)

12

Actions

Enalaprilat (Vasotec)

Inhibits conversion of angiotensin I to angiotensin II. Resulting in decreased afterload and decreased aldosterone sectretion

13

Actions

Epinephrine HCL 1:1000 and 1:10,000

A potent alpha and beta stimulant that increases HR, contractile force, myocardial electrical activity, systemic vascular resistance, BP, and automaticity. Increases myocardial oxygen demand.

14

Actions

Etomidate (Amidate)

Believed to have GABA like effects. The exact mechanism is unknown

15

Actions

Fentanyl (Sublimaze)

binds to opioid receptors

16

Actions

Furosemide (Lasix)

* A potent diuretic that inhibits sodium re-absorption by the kidneys. * Vasodilation of the pulmonary veins

17

Actions

Glucagon HCL

* converts stored glycogen to glucose, increasing blood glucose levels. * improves cardiac contractility and increases heart rate

18

Actions

Glucose, oral

Carbohydrate

19

Actions

Haloperidol (Haldol)

Tranquilizer. Anti-psychotic.

20

Actions

Hydrocortisone (Solu-Cortef)

Glucocorticoid steroid

21

Actions

Hydroxocobalamin (Cyanokit)

Antidote. B12 precursor.

22

Actions

Ipratropium Bromide (Atrovent)

Anticholinergic. Bronchodilator.

23

Actions

Ketamine (Ketalar)

General Anesthetic

24

Actions

Labetalol (Normodyne)

Alpha and Beta blocker

25

Actions

Lidocaine HCL (Xylocaine)

Antiarrhythmic. Local Anesthetic.

26

Actions

Magnesium Sulfate

Electrolite. Anticonvulsant.

27

Actions

MethylPrednisolone (Solu-Medrol)

Anti-inflammatory Steroid

28

Actions

Midazolam HCL (Versed)

Benzodiazepine

29

Actions

Morphine Sulfate

Narcotic. Analgesic.

30

Actions

Naloxone HCL (Narcan)

Narcotic antagonist

31

Actions

Nitroglycerin (Nitrostat)

Nitrate. Vasodilator

32

Actions

Ondansetron (Zofran)

Potent Anti-emetic

33

Actions

Oxygen

binds with hemoglobin and is used in cellular aerobic respiration

34

Actions

Pralidoxime Chloride (2-Pam Chloride)

  • reactivates cholinesterase which has been deactivated by chemical nerve agents and organophosphate poisons.
  • relieves paralysis of the respiratory muscles following chemical nerve agent or organophosphate exposure

35

Actions

Prednisone

reduces inflammation

36

Actions

Prochlorperazine (Compazine0

common neuroleptic actions that result in a decrease in nerve stimulation

37

Actions

Racemic Epinephrine

stimulates both alpha and beta receptors reducing edema and producing bronchodilation

38

Actions

Sodium Bicarbonate

  • drives serum potassium back into the cell
  • enhances urinary excretion of trycyclic acidosis
  • neutralizes acidosis

39

Actions

Sodium Chloride 0.9% (Normalsaline)

Fluid and sodium replacement

40

Actions

Tetracaine HCL

blocks the initiation and conduction of nerve impulses

41

Actions

Tranexamic Acid (TXA Cyklokapron)

Inhibits both plasminogen activation and plasmin activity, thus preventing clot break-down rather than promoting new clot formation. With massive bleeding this may help stabilize clot formation and decrease extravascular bleeding. Onset of action withing 4 hours after IV administration. Exact time of onset unclear and variable.
