Tmax (time to maximum concentration)

Tmax, or "time to maximum concentration," is the period it takes for a drug to reach its highest level in the bloodstream after you take it. It helps determine how quickly a medication starts working. For example, if a drug has a Tmax of 2 hours, it reaches its peak effect two hours after ingestion. Understanding Tmax is important for dosing schedules and predicting how fast a drug will act, ensuring effective treatment while minimizing side effects.
