Study Notes
Peak & Trough Levels
- Utilize peak and trough levels to assess drug concentrations in the body, ensuring patient safety and effectiveness of treatment.
- Essential for determining if a drug dosage needs adjustment due to potential toxicity or inadequate therapeutic effect.
Peak
- Represents the maximum concentration of a drug in the bloodstream.
- Timing is crucial when drawing peak levels; understanding the duration to reach max concentration aids in effective monitoring.
Highest Concentration
- Knowing the maximum concentration level is vital to prevent organ damage, particularly to the liver and kidneys.
- Determining draw times for peak levels depends on several factors, including the drug type, administration method, extended-release properties, and half-life.
Trough
- Trough levels reflect the lowest concentration of a medication before the next dose is administered.
- Typically measured 30 minutes before the scheduled next dose to ensure therapeutic levels are maintained.
Lowest Level of Therapeutic Range
- Medications possess varied therapeutic ranges, indicating the safe and effective dosage needed for treatment.
- Staying within the nontoxic range is crucial for patient safety and treatment efficacy.
Obtain Before Next Dose
- Trough levels are drawn prior to the next medication dose to evaluate if adjustments are necessary.
- Findings may lead to skipping the next dose or reducing the amount for patient safety as indicated by concentration levels.
Half-Life
- Refers to the duration required for the body to eliminate half of the drug's active dose.
- Critical for managing medication drips, especially in cardiac treatments; shorter half-life drugs require more rapid titration compared to those with longer half-lives.
