1. (Efficacy/potency) refers to the degree to which a drug is able to produce maximal effects. Which is correct?
Homework Answers
Answer: Efficacy refers to the degree to which a drug is able to produce maximal effects, efficacy measures the therapeutic effectiveness of the drug in humans. Efficacy depends upon the number of drug receptors complexes formed and coupling of the activation of the receptors. Whereas potency can be defined as the strength of the drug.

A drug loses decayrate percent
of its potency every month. Also, a drug is considered expired if
it loses more than 50% potency. Your goal is to write a function
WhenExpired(decayrate) that returns the number of months after
which the drug is considered expired.
Expected Value Notes WhenExpired(4.0) should return 6 16 WhenExpired(0.5) should return 16 1 WhenExpired(55.5) should return 3 When Expired(12) should return 3 | WhenExpired(0) should return 0 WhenExpired(-1.0) should return 0 O WhenExpired(100) should return 0...

Define pharmacodynamics and its relationship to the action of drugs on the body. Discuss dose-response relationships (e.g., basic features of the dose-response relationships, maximal efficacy, and relative potency), the effects drugs can produce, and the amount of drug needed to elicit an effect. Discuss properties of drug-receptor interactions (e.g., drug receptors, four primary receptor families, receptors and selectivity for drug action, theories of drug-receptor interaction, agonists, antagonists, partial agonists, and regulation of receptor sensitivity). Describe how receptors function in the...

In a study to evaluate drug efficacy, the manufacturer of a new type of generic drug for treating a disease wants to investigate the effectiveness of this generic drug as compared to the traditional brand name drug, At the present time, the brand name drug is the only approved treatment for the disease. Patients diagnosed with the disease have low concentration of a specific factor in their blood. Treatment with the brand name drug will result in an increase in...
