Serum Triamcinolone Levels following Cervical Interlaminar Epidural Injection

Figure 2

Graph of triamcinolone plasma concentration versus time comparing cervical versus lumbar epidural administration of triamcinolone acetonide. The black circles and gray diamonds represent the mean plasma levels of cervical and lumbar administration, respectively. While the pharmacokinetic profile is similar, the T_max is earlier and T_1/2 is shorter for the cervical compared to the lumbar ESI. The lumbar data are from previously published data [7].
