Adrenaline Pharmacology |
Adrenaline is a naturally occurring alpha and beta-adrenergic stimulant. Its actions are: * Increase heart rate by increasing firing rate of the SA node. * Increases the conduction velocity through the AV node * Increases the myocardial contractililty * Increases the irritability of the ventricles. * Causes bronchodilatation (beta 2) * Causes peripheral vasoconstriction (Alpha) |
|
|
Aspirin Pharmacology |
An Analgesic, antipyretic, anti-inflammatory and antiplatelet aggregation agent
Actions: * To minimise platelet aggregation and thrombus formation in order to retard the progression of coronary artery thrombosis in ACS. * Inhibits synthesis of prostaglandins - anti-inflammatory actions. |
|
|
Ceftriaxone Pharmacology |
Cephalosporin antibiotic |
|
|
Dextrose 10% Pharmacology |
A slightly hypertonic crystalloid solution Composition: Sugar - 10% dextrose and water Actions: Provides a source of energy, supplies the body with water |
|
|
Fentanyl Pharmacology |
A synthetic opioid analgesic. Actions: CNS Effects * Depression - leading to analgesia * Respiratory depression - leading to apnoea * Dependence (addiction) * Decreased conduction velocity through the AV node |
|
|
Glucagon Pharmacology |
Glucagon is a hormone naturally excreted by the pancreas. Actions: Causes an increase in blood glucose concentration by converted stored liver glycogen to glucose. |
|
|
Glyceryl Trinitrate (GTN) Pharmacology |
Principally, a vascular smooth muscle relaxant. Actions: * Venous dilation, promoting venous pooling, reducing venous return (decreased preload) * Arterial dilation reducing systemic vascular resistance (decreased after load) * Reduced myocardial O2 demand * Reduced systolic, diastolic and mean arterial pressure whilst usually maintaining coronary perfusion pressure. * Mild-collateral coronary arterial dilation may increase blood supply to ischemic area or myocardium. * Mild tachycardia secondary to a drop in BP * Preterm Labour: Uterine quiescence in pregnancy. |
|
|
Ipratropium Bromide Pharmacology |
Anticholinergic bronchodilator. Actions: Allows bronchodilations by inhibiting cholinergic bronchomotor tone. (i.e. blocks vagal reflexes which mediates bronchoconstriction). |
|
|
Lignocaine 1% Pharmacology |
Lignocaine is a local anesthetic agent. Actions: Prevents initiation and transmission of nerve impulses, causing local anesthesia (1% solution) |
|
|
Methoxyflurane Pharmacology |
Inhalation analgesic at low concentrations |
|
|
Midazolam Pharmacology |
Short acting CNS depressant Actions: * Anxiolytic * Sedative * Anti-convulsant |
|
|
Morphine Pharmacology |
An opioid analgesic Actions: CNS Effects * Depression (leading to analgesia) * Respiratory depression * Depression of cough reflex * Stimulation (changes of mood, euphoria or dysphoria, vomiting, pin-point pupils) * Dependence (addiction) * Vasodilation * Decreased conduction velocity through the AV node |
|
|
Naloxone Pharmacology |
An opioid antagonist Actions: * Prevents or reverses the effects of opioids |
|
|
Normal Saline Pharmacology |
An isotonic crystalloid solution Composition: * Electrolytes (sodium and chloride in a similar concentration to that of extracellular fluid) * Increases the volume of the intravascular compartment |
|
|
Paracetamol Pharmacology |
An analgesic and antipyretic agent |
|
|
Prochlorperazine Pharmacology |
An anti-emetic Actions: * Act on several central nervous neuro-transmitter systems |
|
|
Salbutamol Pharmacology |
A synthetic beta adrenergic stimulant with primarily beta 2 effects. Actions: * Causes bronchodilatation |
|
|
Water for Injection Pharmacology |
Water for injection is a clear, colourless, particle free, odourless and tasteless liquid. It is sterile, with a pH of 5.6 to 7.7 and contains no antimicrobial agents. |
|
|
Ondansetron Pharmacology |
Anti-emetic Action: 5HT3 antagonist which blocks receptors both centrally and peripherally. |
|
|
Oxytocin Pharmacology |
A synthetic oxytocic. Actions: Simulates smooth muscle of the uterus producing contractions. |
|
|
Heparin Pharmacology |
Anticoagulant, inactiaves clotting factors IIa (thrombin) and Xa by binding to antithrombin III. |
|
|
Tenecteplace Pharmacology |
Fibrinolytic, a modified form of a tissue plasminogen activator (tPA) that binds to fibrin and converts to plasminogen to plasmin. |
|
|
Dexamethasone Pharmacology |
A corticosteroid secreted by the adrenal cortex.
Actions: Relieves inflammatory reactions Provides immunosuppression. |
|
|
Ketamine Pharmacology |
Anaesthetic agent with analgesic properties at lower doses. Exact mechanism pf action is uncealr, but primarily works as an antagonist at N-methyl-D-asparate (NMDA) receptors. Ketamine may also interact with opioid, muscarinic and other receptors. Produces a trance-like dissociative state with amnesia, with preservation of laryngeal and pharyngeal reflexes. |
|
|
Olanzapine Pharmacology |
Atypical antipsychotic - antagonist at multiple receptor sites, particularly serotonin (5-HT), dopamine and histamine.
