Phenylephrine, midodrine | Alpha 1 agonist |
Doxazosin | Alpha 1 antagonist |
Clonidine | Alpha 2 agonist |
Dobutamine | beta 1 agonist |
Salbutamol | beta 2 agonist |
Mirabegron | Beta 3 agonist |
Metoprolol | Beta 1 antagonist |
Adrenaline is a beta agonist used for: | Asystole |
What is dobutamine and what is it used for | Beta 1 agonists used to treat cariogenic shock |
Salbutamol and its uses | Selective beta 2 agonists for asthma and delay of premature labour |
Problems with salbutamol | Acts on beta 2 receptors causing vasodilation which initiates the baroreceptor reflex which increases HR and can cause tachycardia and arrythmias |
What is salmeterol | Longer lasting salbutamol for more severe asthma |
Phenylephrine alpha agonist | vasoconstriction |
Doxazosin alpha 1 | Causes vasodilation to treat hypertension and raynaud's syndrome |
Beta blockers e.g. proranolol beta 1&2 metoprolol beta 1 and at | Negative chronotropic actions decreasing work done by the heart and anit-platelet aggregation |
Carvedilol | Mixed alpha and beta adrenoreceptor antagonist |
Other uses of antagonist | hypertension (doxaszosin) |
tyramine, ephedrine, amphetamine act as indirect | sympatheticomimetics |
Phenelzine and iproniazd | MAO blockers |
2 main subtypes | MAO A MAO B |
Selegiline | Selective MAO b inhibitor |
Entacapone | catechol o-methyltransferase |
Corticosteroids split into | Glucocorticoids and mineralcorticoids |
Corticostreroids are synthesied in the | adrenal medulla |
What is our endogenous glucocorticoid | Cortisol |
