Distinct pharmacokinetic profile and safety of a fixed-dose tablet of sumatriptan and naproxen sodium for the acute treatment of migraine.

Objective: To describe the pharmacokinetic and safety profiles of sumatriptan 85 mg formulated with RT Technology (RT) and naproxen sodium 500 mg in a fixed-dose combination tablet (sumatriptan/naproxen sodium) that targets both serotonergic dysmodulation and inflammation in migraine.

Methods: Six open-label, crossover studies were conducted in healthy volunteers (Studies 1, 2, 3, 4, 5) or patients with migraine (Study 6).

Results: Consistently across studies, naproxen administered as a component of sumatriptan/naproxen sodium demonstrated a delayed-release profile similar to that of an enteric-coated product.

Effects of cilomilast, a selective phosphodiesterase 4 inhibitor, on esophageal motility and pH, and orocecal and colonic transit: two single-center, randomized, double-blind, placebo-controlled, two-part crossover studies in healthy volunteers.

Background: Phase IIb studies have reported that cilomilast, a selective phosphodiesterase 4 inhibitor being developed for the treatment of chronic obstructive pulmonary disease, is associated with gastrointestinal (GI) adverse effects (AEs) in a small proportion (approximately 5%) of individuals.

Objectives: The aims of these 2 studies were to investigate the effects of cilomilast 15 mg BID on: (1) lower esophageal sphincter pressure (LESP) and esophageal body motility and pH (study 1); and (2) orocecal and whole-gut transit times (OCTT and WGTT, respectively) (study 2) in healthy volunteers.

Methods: These 2 randomized, double-blind, placebo-controlled, 2-part crossover studies were conducted at the Neurogastroenterology Unit, Wythenshawe Hospital, Manchester, United Kingdom (study 1) and GlaxoSmithKline, Harlow, United Kingdom (study 2).
