aspirin
class description |
CLASS: Analgesic, anti-inflammatory, antipyretic, antiplatelet
DESCRIPTION: Aspirin decreases inflammation, blocks pain impulses in the central nervous system, dilates peripheral vessels, and decreases platelet aggregation. The use of aspirin is strongly recommended for all patients with acute myocardial infarction. |

DOSAGE AND ADMINISTRATION
Adult: Mild pain and fever: 325-650 mg PO q 4 hr Myocardial infarction: 160-325 mg PO (chewing is preferable to swallowing) Pediatric (over 12 years of age): Mild pain and fever—40-100 mg/kg/day in divided doses SPECIAL CONSIDERATIONS Pregnancy safety: Category D Should be given as soon as possible to the patient with acute myocardial infarction |

atropine
class description |
CLASS: Anticholinergic agent
DESCRIPTION: Atropine sulfate (a potent parasympatholytic) inhibits actions of acetylcholine at postganglionic parasympathetic (primarily muscarinic) receptor sites. Small doses inhibit salivary and bronchial secretions; moderate doses dilate pupils and increase heart rate. Large doses decrease gastrointestinal motility, inhibit gastric acid secretion, and may block nicotinic receptor sites at the autonomic ganglia and at the neuromuscular junction. Blocked vagal effects result in increased heart rate and enhanced atrioventricular conduction with limited or no inotropic effect. In emergency care, atropine primarily is used to increase the heart rate in life-threatening or symptomatic bradycardia and to antagonize excess muscarinic receptor stimulation caused by organophosphate insecticides or chemical nerve agents (e.g., sarin and soman). |

ONSET AND DURATION
Onset: Rapid Duration: 2-6 hr INDICATIONS: Hemodynamically significant bradycardia, Asystole, Pulseless electrical activity with absolute bradycardia Organophosphate or nerve gas poisoning CONTRAINDICATIONS: Tachycardia, Hypersensitivity to atropine, Obstructive disease of gastrointestinal tract, Obstructive uropathy, Unstable cardiovascular status in acute hemorrhage with myocardial , ischemia, Narrow-angle glaucoma, thyrotociosis |

ADVERSE REACTIONS: Tachycardia, Paradoxical bradycardia when pushed too slowly or when used at doses , less than 0.5 mg,
Palpitations, Dysrhythmias, Headache, Dizziness, Anticholinergic effects (dry mouth/nose/skin, photophobia, blurred vision, urinary retention, constipation), Nausea and vomiting, Flushed, hot, dry skin, Allergic reactions, DRUG INTERACTIONS: Use with other anticholinergic agents may increase vagal blockade. Potential adverse effects may occur when administered with digitalis, cholinergics, neostigmine. The effects of atropine may be enhanced by antihistamines, procainamide, quinidine, antipsychotics and antidepressants, and thiazides. Increased toxicity: Amantadine |

HOW SUPPLIED
Parenteral: There are various injection preparations. In emergency care, atropine usually is supplied in prefilled syringes containing 1 mg in 10 mL of solution. SPECIAL CONSIDERATIONS Pregnancy safety: Category C Follow endotracheal tube administration with several positive-pressure ventilations. Atropine causes pupillary dilation, rendering the pupils nonreactive; pupil response may not be useful in monitoring central nervous system status. |

DOSAGE AND ADMINISTRATION
Bradydysrhythmias Adult: 0.5 mg every 3-5 min for desired response (max total dose: 3 mg Pediatric: 0.02 mg/kg IV/IO/endotracheal tube (diluted to 3-5 mL); min dose: 0.1 mg; max single dose of 0.5 mg for a child and 1 mg for an adolescent; may be repeated in 5 min for a max total dose of 1 mg for a child and 2 mg for an adolescent Asystole or Pulseless Electrical Activity Adult: 1 mg IV, endotracheal tube (2-3 mg diluted to a total of 10 mL of NS); may be repeated every 3-5 min (max: 0.03-0.04 mg/kg) Pediatric: Efficacy has not been established. Anticholinesterase Poisoning Adult: 1-2 mg IV push every 5-15 min until atropine effects are observed; then every 1-4 hr for at least 24 hr Pediatric: 0.02-0.05 mg/kg/dose (usual dose 1-5 mg) IV; may be repeated every 10-20 min until atropine effect is observed; then 1-4 hr for at least 24 hr |

morphine
class description |
DESCRIPTION: Morphine sulfate is a natural opium alkaloid that has a primary effect of analgesia. It also increases peripheral venous capacitance and decreases venous return (chemical phlebotomy). Morphine sulfate causes euphoria and respiratory and central nervous system depression. Secondary pharmacological effects of morphine include depressed responsiveness of alpha-adrenergic receptors (producing peripheral vasodilation) and baroreceptor inhibition. In addition, because morphine decreases preload and afterload, it may decrease myocardial oxygen demand. The properties of this medication make it extremely useful in emergency care. Morphine sulfate is a Schedule II drug.

ADVERSE REACTIONS: Hypotension, Tachycardia, Bradycardia, Palpitations, Syncope, Facial flushing, diaphoresis, itching, Respiratory depression, Euphoria, Bronchospasm, Dry mouth, Allergic reaction
DRUG INTERACTIONS Central nervous system depressants may potentiate effects of morphine (respiratory depression, hypotension, sedation). Phenothiazines may potentiate analgesia. MAO inhibitors may cause paradoxical excitation. |

how supplied dosage & administration |
HOW SUPPLIED
Morphine is supplied in tablets, suppositories, and solution. In emergency care, morphine sulfate usually is administered IV. Parenteral preparations are available in many strengths. A common preparation is 10 mg in 1 mL of solution, ampules and Tubex syringes. DOSAGE AND ADMINISTRATION Adult: 2-4 mg slow IV over 1-5 min every 5-30 min; titrated to effect Pediatric: 0.1-0.2 mg/kg/dose IV (max total dose: 15 mg) |

SPECIAL CONSIDERATIONS
Pregnancy safety: Category B (if not used for prolonged periods or in high doses at term); narcotics rapidly cross the placenta Safety in neonates has not been established. Use with caution in the elderly, those with asthma, and in those susceptible to central nervous system depression. Morphine should be used with caution in chronic pain syndromes. Morphine may worsen bradycardia or heart block in inferior myocardial infarction (vagotonic effect). Naloxone should be readily available. |
