Fentanyl pectin nasal spray in breakthrough cancer pain.

Abstract Fentanyl pectin nasal spray (FPNS) is being developed to improve analgesic onset, treatment efficacy, and satisfaction/acceptability in treating breakthrough cancer pain (BTCP). Patients (n = 114) were entered into a randomized, placebo-controlled, double-blind, multicenter study. Patients who successfully titrated (n = 83) entered a double-blind phase; 10 episodes of BTCP were treated with the effective dose (7) or placebo (3).
