Actions and Uses
Actions, uses, and receptors for specific drug categories/meds
Term | Definition |
---|---|
Antipsychotic Uses | Disordered thought processes prolonged N/V Intractable Hiccups |
Antiseizure Uses | prevent/treat seizures prophylactic- brain trauma/surgery psychiatric disorders neuropathies migraines |
Cholinergic Uses | urinary retention myastenia gravis alzheimers glaucoma reverse neuromuscular blockers |
Antipsychotic Action | occupy or block dopamine or serotonin or glutamine receptors |
Antidepressant Action | normalize neurotransmission system |
Antiepileptic Action | stabilize neruonal membrans and decrease neural firing in response to stimuli alter mvmt of Na and/or Ca and/or Mg enhance GABA Lower glutamate |
Alpha Blocker Action | dilate BVs and Lower PVR |
Vasodilator Action | relax smooth muscles in BVs |
Beta Blocker Action | ↓HR ↓Contractillity ↓CO ↓BP ↓Automaticity slow AV conduction ↓glucose metabolism bronchoconstrict cardioprotective |
Cholinergic Action | ↓HR Vasodilate ↑GI tone and secretions ↑Bladder tone ↑bonchoconstrict ↑resp secretions miosis |
Antiadrenergic Action | Block SNS stimulation Block Alpha, Beta 1 or Beta 2 lower BP |
Anticholinergic Action | CNS stimulation then depression ↓Response to vagal stimulation bronchodilate ↓secretions antispasmodic-GI relax bladder mydriasis ↓sweating |
Muscle Relaxer Action | block nerve impulses that cause increased muscle tone and contraction |
Anesthesia Action | Depress CNS function and interfere with nerve transmission loss of sensation loss of consciousness |
Benzodiazepines Action | bind with receptors in the brain stabilize cells and/or enhance GABA |
Adrenergic Uses | *someone is dying cardiac arrest hypotension shock asthma decongestion allergies relax uterine muscles vasoconstriction mydriasis |
Beta 1 Targets | Heart |
Beta 2 Targets | Lungs |
Cholinergic Receptors | nicotinic muscarinic- GI and urinary |
Alpha Receptors | Heart and BVs Affect on BP |
Dopamine Receptors <3 mcg/kg/min | vasodilate (BVs) |
Dopamine Receptors 5-10 mcg/kg/min | increases heart contractility (heart) |
Dopamine Receptors >10 mcg/kg/min | vasocontrict (BP) |
