[[File:AUC.png|right|frameless]]
'''C<sub>max</sub>''' represents the maximum or peak concentration of a drug in the bloodstream after administration. It is a critical [[Pharmacokinetic|pharmacokinetic]] parameter used to assess the drug’s behavior in the body, alongside others like AUC (Area Under the Curve) and T<sub>max</sub> (the time at which C<sub>max</sub> is observed).

===Importance of C<sub>max</sub>===
*'''Efficacy and Safety:''' C<sub>max</sub> is pivotal for determining the safety and efficacy of a drug, as the therapeutic effect of a drug is often related to its concentration in the blood, and excessively high concentrations can lead to adverse effects or toxicity.
*'''Dose Adjustment:''' It is vital for adjusting dosages to avoid subtherapeutic or toxic levels and is instrumental in optimizing drug formulations and dosing regimens during drug development.
*'''Drug Development:''' Understanding C<sub>max</sub> helps researchers in the drug development process optimize the drug’s formulation and dosing regimen.

===Measurement of C<sub>max</sub>===
C<sub>max</sub> is determined through a series of blood samples taken at different times after the administration of the drug. The highest recorded concentration of the drug is deemed the C<sub>max</sub>.

===Relation to Other Parameters===
*'''[[Tmax|T<sub>max</sub>]]:''' Represents the time at which C<sub>max</sub> is observed.
*'''[[Area Under the Curve (AUC)]]:''' Represents the total drug exposure over time, providing information about the overall exposure, reflecting both the extent of absorption and the elimination rate of the drug.

===Considerations===
The value of C<sub>max</sub> can vary significantly between individuals due to factors such as metabolism, age, weight, sex, and the presence of other medications. It is typically presented as a range or average value in pharmacokinetic studies.
