Task: Question Generation
Input (English): Passage: Elimination Gabapentin is elimination (pharmacology) renally in the urine. It has a relatively short elimination half-life, with a reported value of 5.0 to 7.0 hours. Similarly, the terminal half-life of gabapentin enacarbil IR (as active gabapentin) is short at approximately 4.5 to 6.5 hours. The elimination half-life of gabapentin has been found to be extended with increasing doses; in one series of studies, it was 5.4 hours for 200 mg, 6.7 hours for 400 mg, 7.3 hours for 800 mg, 9.3 hours for 1,200 mg, and 8.3 hours for 1,400 mg, all given in single doses. Because of its short elimination half-life, gabapentin must be administered 3 to 4 times per day to maintain therapeutic levels. Conversely, gabapentin enacarbil is taken twice a day and gabapentin XR (brand name Gralise) is taken once a day.
Output (English): What hour is the shortest amount of time to take Gabapentin?
