Parmacology

9 important questions on Parmacology

What other organs are involved in excretions

liver, GI tract, lungs, exocrine glands

What are 4 concepts relevant to drug effectiveness

Onset peak and duration of drug action, therapeutic range, bioavalibility, concentration of drug at target sites

Define onset, peak, and duration

onset-time needed for drug to reach high enough blood level for its effects to appear, duration- time the med has a pharmacological effect, peak- the meds highest levels

What is therapeutic range

onset of action, serum of drug level is minimal

What is therapeutic level

blood serum produces desires effect without toxicity

What is biological half-life of a medication

amount of time it takes for half the drug to be eliminated

What are some factors that affect pharmacokinetics

age: young-sm dose old-large dose, weight: more weight higher the dose, sex: women have less muscle and different hormones, environment, pregnancy, rout of admin: rout influences the amt of drug absorbed, timing of admin: absent of food affects oral meds and their actions, fluid: dehydration affects absorption

What are primary effects

(therapeutic) predicted, intended, and desired. short and the reason the drug was prescribed

What are secondary effects

(non-therapeutic) unintended unpredictable and undesirable
