Treatment
Verapamil HCl, capsules for oral administration, 80mg, TID, for 8 weeks Verapamil HCl: Verapamil represents a calcium channel blocker which binds to the alpha subunit of L-type voltage dependent calcium (Cav1) channels thereby blocking the influx of calcium ions into the host cell. While Verapamil is classically used to promote the relaxation of cardiac and smooth muscle cells, recent evidence has suggested that it may also function as an immunomodulator in astrocytes, hepatocytes, and T-cells. Further research has demonstrated that Verapamil is capable of specifically reducing Th2 associated inflammation in asthma. These findings raise the provocative question as to whether Verapamil could also be effective in reducing inflammation in chronic rhinosinusitis with nasal polyps.

Placebo, capsules for oral administration, TID, for 8 weeks Placebo: Capsule with the same characteristics (size, color, smell) as Verapamil HCl.
