Hydralazine
Dobutamine
- Selective B1 receptor agonist
- Commonly used in treatment of shock and cardiac arrest
- Duration: roughly 2 minutes
- Acts fairly specifically on the heart (due to limited tissue distribution of b1 receptors); inotropic effects are much more prominent than chronotropic effects (relative to epinephrine)
- Used in stress tests to reveal cardiac abnormalities
Albuterol
- selective b2-adrenergic receptor agonist
- treatment of asthma
- Route: orally or by inhalation
- Duration: half-life of several hours (relatively poor substrate for MAO
- Side Effects: tachycardia, elevated blood glucose levels, and skeletal muscle tremor
- Contraindications: cardiac disease & diabetes
Clonidine
- a2-adrenergic receptor agonist
- treatment of hypertension, eyedrop solutions to reduce eye irritation (constrict inflamed blood vessels) or treat glaucoma (reduce intraocular pressure)
- Route: oral
- Duration: several hours
- MOA: anti-hypertensive effects via activation of presynaptic a2 receptors in CNS, which suppresses sympathetic activation
- Side Effects: dry mouth and sedation
Phenelzine
- Inhibits monoamine oxidase activity
- MOA: indirectly-acting sympathomimetic drugs
- Route: Oral
- Tx: depression, due to effects on CNS receptors
- Duration: half-life 24 hr
- Side Effects: potentially fatal hypertensive crisis if combined improperly with other sympathomimetics or with foods rich in amines (wine, cheese, beer, chocolate, etc.)
Methylphenidate (Ritalin)
- bind to re-uptake transporters (NET) and vesicular transporters (VMAT) to cause reverse catecholamine transport (Indirect acting)
- Route: oral
- Duration: half-life of several hrs
- Tx: attention deficit disorder (ADHD) and narcolepsy
- Side Effects: mild hypertension, tachycardia, insomnia and gastrointestinal problems
Pseudoephedrine
- amphetamine-like drugs that bind to transporters and cause catecholamine release (indirectly-acting)
- Route: oral
- Duration: half-life of several hrs
- Tx: Nasal decongestant
- does not efficiently cross the blood brain barrier and has few effects on the CNS, which is its major difference from methylphenidate and amphetamine
Propranolol (Inderal)
- non-selective b-adrenergic receptor antagonist
- Decreases cardiac output by reducing both heart rate, the strength of cardiac ventricular contraction,
- Route: oral
- Duration: half-life of several hours
- Tx: hypertension, heart disease, angina, cardiac arrhythmias and muscle tremor plus the inhibition of B1 receptors in the juxtaglomerular region of the kidney, which inhibits the release of renin
- Contraindications: asthma, since inhibition of b2 receptors in the lung may cause bronchoconstriction
Metroprolol (Lopressor)
- selective b1-adrenergic receptor antagonists
- Route: oral
- Duration: half-life of several hours
- Tx: hypertension, heart disease, angina and certain cardiac arrhythmias
Phentolamine
- non-selective a-adrenergic receptor antagonist
- Route: oral
- Duration: half-life of several hours
- Tx: pheochromocytoma, a tumor of the adrenal medulla that causes massive release of epinephrine and profound sympathetic over-activation (leading to severe hypertension, cardiac problems, etc.)
- induces severe hypotension
- reverses hypertensive crisis (patient on MAO inhibitors who consumes too much wine and cheese)
Prazosin
- selective a1-adrenergic receptor antagonists
- Route: oral
- Duration: half-life of several hours
- Tx: hypertension and BPH (the prostate is rich in a1 receptors, which when over-activated in the long-term accelerate cell growth)
Yohimbine
- selective a2-adrenergic receptor antagonist
- Route: oral
- Duration: half-life of several hours
- Tx: sexual dysfunction…mechanism of action is inhibition of a2 receptors in the CNS, so it’s the opposite of clonidine
- Side Effects: hypertension, sleep disturbances and various CNS effects…it can be dangerous to combine with sympathomimetics (esp. MAO inhibitors)
Reserpine
- binds to the vesicular monoamine transporter (VMAT) and blocks it, thereby blocking vesicular packaging and release of catecholamines (indirect acting)
- Route: oral
- Duration: long half-life (36 hours)
- Tx: Raynaud’s Syndrome (pathological, painful vasoconstriction of blood vessels in the distal limbs)
