Week 2 Assignment – Half-Life Calculation
Assignment Instructions
Imagine you are trying to help a colleague understand some basic concepts about psychopharmacology. Write a brief paper to address the following:
- Explain the concept of half-life for a drug.
- Differentiate between half-life and steady state.
- Explain the difference between potency and effectiveness of a drug.
- Respond to the following scenario:
- If a drug has a half-life of six hours, how long will it take for the drug to be eliminated from the body after administration of a single dose? Explain how you arrived at that particular cutoff score for complete elimination. Show your calculations on a timeline or graphs to illustrate the changes from 100 percent of the initial dose to your endpoint for complete elimination.
Additional Requirements
- Length: 2–3 pages of content plus title, abstract, and reference pages.
- References: Include at least one current, scholarly reference from a peer-reviewed academic journal or academic book. References should be no older than 5 years.
- Formatting: Use current APA formatting, including correct in-text citations, proper punctuation, double spacing throughout, proper headings and subheadings, no skipped lines before headings and subheadings, proper paragraph and block indentation, no bolding, and no bullets. You must also use the proper APA style to list your references. Refer to APA Style and Format (linked in Resources) for more information.
- Avoid stigmatizing language.
