Pharmacokinetics of a granisetron transdermal system for the treatment of chemotherapy-induced nausea and vomiting

Abstract

Objective: To determine the pharmacokinetic (PK) profile of granisetron transdermal formulation and examine its possible relationship with age, gender, and renal function.

Methods: This article describes a Phase I PK study and a post hoc pooled population PK analysis. The Phase I study was a randomized, cross-over study that assessed PK parameters of three granisetron patch sizes and oral granisetron. The pooled population PK analysis included data from three trials in healthy subjects (n = 48) and from Phase II and III studies in patients with cancer (n = 793). The population PK model was used to investigate granisetron exposure and its possible relationship with age, gender, and renal function.

Results: Following oral dosing, plasma granisetron concentration was quantifiable at 1 h, and maximal mean concentration (4.7 ng/mL) was reached 2 h after administration. With transdermal application, maximal concentration was reached 48 h post-application; t(1/2) was 36 h. With oral dosing, overall exposure after 5 days was 306 ng/mL.h, and C(avg) 2.6 ng/mL. This corresponded to an AUC(0-infinity) for the 52 cm(2) patch of 420 ng/mL.h and C(avg) 2.2 ng/mL over 6 days. Clearance was not affected by age, gender, weight, or renal function.

Conclusion: The 52 cm( 2) granisetron patch achieves a similar exposure to that of a 2 mg oral dose and provides continuous delivery of granisetron over 6 days. The patch may have utility in treating chemotherapy-induced nausea and vomiting where prolonged drug delivery is advantageous. No dose adjustments would be needed based on age or renal function.
