A run chart showing how Plasma Hydromorphone Concentration (ng/mL) (on the y-axis) changes over time (on the x-axis) for pain patients that ingest one dosage of 32 mg OROS hydromorphone. The Concentration is measured in ng/mL from 0.0001 to 10.0000 but is not drawn to scale. The Time is measured in hours from 0 to 30 in 6 hour increments and is drawn to scale. The data shows that the dosage of hydromorphone takes approximately 2 hours to climb from zero (presumably) to 0.1000 ng/mL climbs steadily for another 4 hours until it reaches 3.0000 ng/mL climbs steadily for another 6 hours until it reaches 5.0000 ng/mL then drops steadily for the next 18 hours until it reaches 2.0000 ng/mL. Exact values in ng/mL are not listed however and the idiosyncratic scaling makes precise readings difficult. The background is white and gray with graphic elements in blue and text in black.
