1 RESULTS: Both substance P binding and Ca2+ increase were inhibited half-maximally by approximately 1 mM bupivacaine at pH 7.5, whereas tetracaine, lidocaine, and benzocaine were slightly less potent at inhibiting binding. Bupivacaine tachykinin 1 Mus musculus
2 Concentration-dependent substance P-binding studies showed that bupivacaine"s inhibition was not competitive. Bupivacaine tachykinin 1 Mus musculus
3 Inhibition of substance P binding by bupivacaine increased with increasing pH, but the protonated species appears to have some inhibitory activity, and quaternary lidocaine also inhibited binding. Bupivacaine tachykinin 1 Mus musculus
