Document Content and Description Below

Factors that Determine the intensity of drug responses a Prescribed Dose (Administration) 1 Dosage size, route, & timing of administration are important determinants of drug responses 2 Because of... poor patient adherence & medication errors, drugs are not administered as they are prescribed 3 Toxicity = drug is too high; Treatment failure = drug is too low b Administered Dose (Pharmokinetics) 1 Determines how much of administered dose gets to its site of action 2 Four major processes: absorption, distribution, metabolism, & excretion 3 Impact of body on drugs c Concentration at sites of action (Pharmodynamics) 1 Determines nature and intensity of response 2 Impact of drugs on the body 3 Drug-receptor interaction, patient’s functional state, & placebo effects d Sources of Variation: 1 Drug Interactions 2 Physiological Variables (age, gender, weight) 3 Pathological Variables (diminished functions of kidneys and liver, major organs of drug elimination) 4 Genetic Variable (can alter metabolism of drugs and predispose patient to unique interactions) Because all patients are unique, drug therapy must be tailored to each individual.
