Pharmacology Flashcards
What is the general pharmacology for adrenaline?
Synthetic alpha and beta stimulant.
Beta1: increases SA node firing rate
Increase conduction velocity in AV node
Increase myocardial contract ability
Increase ventricles irritability
Beta 2: bronchodilation
Alpha: peripheral Vaso constriction
What is the general pharmacology for glucagon ?
Naturally converts stored liver glycogen into glucose.
What is the general pharmacology for GTN?
Vascular smooth muscle relaxant. Reduces myocardial oxygen demand.
Causes venous and arterial dilation (reduces preload and afterload).
Reduces
What is the general pharmacology for atrovent?
Blocks vagal reflexes which mediate broncho constriction
What is the general pharmacology for salbutamol?
Synthetic beta adrenergic stimulant for beta 2 effects.
What are the 8 critical illnesses for oxygen therapy?
Cardiac arrest Major trauma/ head injury Carbon monoxide poisoning Shock Severe sepsis Anaphylaxis Decompression illness Status epilepticus
What is the general pharmacology for aspirin?
4A ‘s: analgesia, anti platelet aggregation, anti inflammatory, antipyretic.
Inhibits prostaglandin synthesis
What is the general pharmacology for ceftriaxone?
Cephalosporin antibiotic
What is the general pharmacology for fentanyl?
A synthetic opioid analgesic has 3 CNS effects and 1 cardiovascular effect. CNS depression, respiratory depression, dependence, decrease conduction velocity of AV node
What is the general pharmacology for Maxalon?
Antiemetic- dopamine receptor antagonist
Accelerates gastric emptying and peristalsis
What is the general pharmacology for midazolam?
Short acting CNS depressant which acts as a sedative and an anti convulsant
What is the general pharmacology for misoprostol?
A synthetic prostaglandin which enhances uterine contraction
What is the general pharmacology for morphine?
An opioid analgesic
CNS depression
Respiratory depression
Depression of cough reflex
Vasodilation
Decrease conduction velocity of AV node
