What is the gold standard for initial drug selection? CORRECT ANSWERS✅ - pharmacokinetic factors -pharmacodynamics factors -therapeutic factors -safety -cost to society -pt factors -provider factors -alternative therapies What are some pharmacodynamics factors that influence drug selection? CORRECT ANSWERS✅ -ease of medication titration is influenced by the dose- response curve of the drug -therapeutic index: narrow is more difficult to manage vs wide is safer and requires less monitoring /wide range of safe doses What are the 5 pharmacokinetic factors that influence drug selection? CORRECT ANSWERS✅ -bioavailability (%, ex. Digoxin -CYP 450 metabolism -renal elimination (if high, may not be app for CKD pt for example) -dose-concentration curve -half life How is the safety profile of a drug initially determined, and where in the drug monograph may safety concerns be found? CORRECT ANSWERS✅ clinical trials. outlined in the cautions and precautions section of the drug monograph. also pay attention to medwatch report and FDA advisories

2: cannot be refilled 3: telephone prescription okay 4:telephone prescription okay 5: same as all prescription drugs Identify measures that prescribers can use to ensure the security of their DEA number and prescription pads.

Define Electronic prescribing or "e-prescribing". CORRECT ANSWERS✅ sending a prescription from computer or printing from computer without writing it What are benefits of E-prescribing?

CORRECT ANSWERS✅ they have to be a patient, not a family or friend, pt must have been assessed and there should be a record of this in chart that is linked to prescription What two groups are at the highest risk for adverse drug reactions (ADRs)? CORRECT ANSWERS✅ infants/children. the elderly What actions by the prescriber can reduce the possibility of drug-drug interactions, and subsequent ADRs? CORRECT ANSWERS✅ -consider what medications the pt is on, pay attention to who is at high risk for ADR, always document the med, strength, and FRREQUENCY of med taken by pt, Identify the recognized types of ADRs, definition, cause, and examples of each. CORRECT ANSWERS✅ type A: dose dependent. r/t effects of drug. e.g. insulin and BS too low
type B: drug allergy or hypersensitivity. not dose dependent or predictable/preventable. type 1- type C: r/t cumulative dose of med. relatively uncommon. type D: delayed rxn that is apparent some time after drug is used (teratogenic/carcinogenic) type E: r/t withdrawal of drug type F: unexpected failure of drug. can be caused by drug interactions The presence and severity of teratogenesis depends upon what 3 factors? CORRECT ANSWERS✅ 1. Genetic susceptibility -interpatient variation in susceptibility exists. This means that not every baby exposed to a teratogen will exhibit effects of the drug.
