Understanding Total Absorption: How 0.8 mg/hour Multiplies to 57.6 mg Over 72 Hours When evaluating drug bioavailability, one crucial metric is total absorption, a measure that determines how much of a drug enters the bloodstream over time. A common calculation used in pharmacokinetics is straightforward but powerful: multiplying the absorption rate by duration to find total absorbed dose. For example, if a medication is absorbed at a constant rate of 0.8 mg per hour, over a full 72-hour period, the total absorption is: 0.8 mg/hour × 72 hours = 57.6 mg
