Mechanism of action

  1. Atropine
    Increases heart rate, Competes reversibly with acetylcholine.
  2. Adenosine
    Slows the conduction of electrical impulses at the AV node.
  3. Albuterol
    Stimulates Beta 2 adrenergic receptors (relaxes bronchial smooth muscles)
  4. Amiodarone
    Delays repolarziation and increases the duration of the action potential. Slows sinus rate, increases PR and QT intervals, decreases peripheral vascular resistance.
  5. Aspirin
    Prevents formation of thromboxane A2 (platelet inhibitor) Anti-inflammatory.
  6. Calcium Chloride
    Increases cardiac contractility.
  7. Ditiazem (Cardizem)
    Prolongs conduction of electrical impulses through the AV node. Causes vasodilation. Decreases rate of ventricular response. Decreases myocardial oxygen demand.
  8. D50W
    Increases blood glucose concentrations.
  9. Diazepam (Valium)
    Enhances the effects of GABA. Can produce any level of CNS depression (including sedation, muscle relaxation, anticonvulsant activity)
