Action Flashcards
(25 cards)
What is the action of Glucose Gel?
Principal energy source for body cells, especially the brain
What is the action of Adrenaline?
• Stimulates the ALPHA and BETA receptors of the sympathetic nervous system to produce the “Fight” or “Flight” reaction
• ALPHA stimulation causes peripheral vasoconstriction. It raises the perfusion pressure of vital organs during cardiac arrest and it decreases capillary permeability and increases blood pressure in anaphylaxis
• BETA 1 stimulation causes increased myocardial excitability, tachycardia, and increased myocardial contractility
• BETA 2 stimulation causes bronchodilation
What is the action of Glucagon?
Converts liver glycogen to glucose. Glucagon may not work if liver glycogen is depleted due to starvation or chronic liver disease
What is the action of GTN?
• Dilates coronary arteries
• Dilates systemic veins and arteries
• Decreases preload, afterload and blood pressure
What is the action of Compound sodium lactate(Hartmann’s)?
Following intravenous infusion it is distributed throughout the extracellular fluid space. Approximately 25% of the volume infused stays in the intravascular space for a variable period of time.
What is the action of Metaclopramide?
Blocks central dopamine receptors
What is the action of Morphine?
• Decreases pain perception and anxiety
• Causes peripheral vasodilation
What is the action of Naloxone?
Reverses symptoms caused by opioid analgesics:
• Respiratory depression
• Sedation
• Hypotension
What is the action of Salbutamol?
Stimulates beta 2 receptors in bronchial smooth muscle resulting in bronchodilation
What is the action of Aspirin?
•Inhibits platelet aggregation thereby limiting thrombus enlargement in acute coronary syndrome
• Reduces production of prostaglandins thereby relieving pain and fever
What is the action of Midazolam?
Reduces seizure activity and has a tranquillising and amnesic effect
What is the action of Methoxyflurane?
Central nervous system depressant
What is the action of Oxygen?
Essential element for aerobic metabolic needs and sustaining life
What is the action of Paracetamol?
Temporary relief of pain and discomfort in arthritis, headache, muscular and neuralgic conditions; also reduces fever
What is the action of Ipratropium Bromide?
• Bronchodilation
• Blocks vagal reflexes which mediate bronchoconstriction
• Synergistic when used in combination with salbutamol
What is the action of Fentanyl?
• Potent analgesic
• Effective drug for intranasal use because it is rapidly absorbed across mucous membranes
What is the action of Benzyl Penicillin?
Inhibits bacterial cell wall synthesis and causes cytolysis when the bacterium tries to divide
What is the action of the Influenza Vaccine?
Induces antibodies against the surface antigens of the influenza virus
What is the action of Ibuprofen?
• Provides anti-inflammatory and analgesic effects
What is the action of Tenecteplase?
• Dissolves coronary artery thrombi facilitating myocardial reperfusion
• Activates the fibrinolytic system to degrade the fibrin matrix of a thrombus
What is the action of Enoxaparin Sodium?
• Reduces reinfarction & ischaemia complications after lysis of STEMI
• Inhibits thrombin generation
• Inhibits coagulation factors Xa and thrombin
• Induces a sustained release of tissue factor pathway inhibitor
What is the action of Glucose 10%?
Principal energy source for body cells, especially the brain
What is the action of Ondansetron?
Blocks central and peripheral 5-HT3 receptors
What is is the action of Fexofenadine?
Non-sedating anti-histamine
