Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is a widely used tool for the depletion of neuropeptides from sensory C-fibres. Upon capsaicin treatment tachykinins are released, resulting in a variety of responses in the airways. We showed that after capsaicin (0.3 microM; 30 min) treatment of guinea pig tracheal smooth muscle preparations, the maximal contraction of the trachea after methacholine stimulation was strongly increased (capsaicin: 1.147 +/- 0.050 g vs. control: 0.717 +/- 0.047 g). This effect was completely nullified after pretreatment with capsazepine (2-[2-(4-chlorophenyl)ethyl-amino-thiocarbonyl]-7,8-dihydroxy-2,3, 4,5-tetrahydro-1H-2benzazepine; a vanilloid receptor antagonist) and YM38336 (a dual tachykinin NK1 and tachykinin NK2 receptor antagonist). Our results serve as a warning against using capsaicin as a putatively clean pharmacological tool to deplete the neuropeptides from pools on the C-fibres because we showed that capsaicin also strongly influences basal mechanisms in tracheal smooth muscle control.
