Digoxin (Lanoxin) - Exerts positive inotropic action on myocardium (inc force of myocardial contraction) l/t improve mechanical efficiency of heart as blood pumping organ. Slows AV node conduction. Ultimately reduce heart size (negative chronotropic effect) & improved renal blood flow. Propranolol (Inderal) - Blocks sympathetic (adrenergic) stimulation l/t decreased heart rate, reduce contractility & slows electrical conduction in heart. Dilitiazem HCl (Cardizem) - Reduce influx o...

The study of the biochemical and physiological effects of drugs and the molecular mechanisms by which those effects are produced. • Pharmacokinetics: the impact of the body on drugs. There are four pharmacokinetic processes - drug absorption, drug distribution, drug metabolism, and drug excretion • Pharmacotherapeutics: the use of drugs to diagn...

1. -Discuss the use of metered-dose inhalers (MDIs) and the sequencing of medications. - ..• Metered-dose inhalers (MDIs) are small, hand-held, pressurized devices that deliver a measured dose of drug with each actuation. Dosing is usually accomplished with 1 or 2 puffs. When 2 puffs are needed, an interval of at least 1 minute should separate the first puff from the second. When using an MDI, the patient must begin to inhale prior to activating the device. Hence, hand-lung coordination is r...
