Lowest concentration
- Peak and trough levels indicate drug levels in an individual’s body. A peak is the highest level of a medication in the blood, while a trough level indicates the lowest concentration. Troughs of medication concentration occur after the drug has been broken down and metabolized by the body.

In medicine and pharmacology, a trough level or trough concentration (C trough) is the concentration reached by a drug immediately before the next dose is administered, [1] [2] often used in therapeutic drug monitoring.
As mentioned previously, the trough is a single exposure point estimate at the end of the dosing interval. For vancomycin and most drugs, the trough concentration just prior to the next dose is the lowest concentration observed in the dosing interval.
A trough level is drawn when the drug is at its lowest in the bloodstream, right before the next scheduled dose is given. Medications have a predicted reference range of normal values for peak and trough levels.

The term ‘trough concentration’ implies that a blood sample is taken immediately before the next dose is due. In practice, there is a large variability in the timing of ‘trough’ sampling [14]. For a drug with a half-life of approximately 6 h (as in normal renal function), variability in timing of blood sampling can add to imprecision in ...
Oct 31, 2023 · Osmoconformers decrease the net flux of water into or out of their bodies from diffusion. They maintain internal solute concentrations within their bodies at a level equal to the osmolarity of the surrounding medium. The body is subject to a continual intake and loss of water and electrolytes.
Mar 29, 2021 · Both graphs have two main peaks – at the blue-violet region and the red region of the light spectrum. Both graphs have a trough in the green-yellow region of the light spectrum. An overlay of the photosynthetic absorption and action spectra shows there is a strong cumulative correlation.
