WebNov 1, 1990 · In rats, RTX (2 ng-5 micrograms/kg i.v.) failed to elicit the full reflex triad (apnea, systemic hypotension and bradycardia); RTX did, however, desensitize the pulmonary chemosensitive receptors to capsaicin and phenyldiguanide. This effect is not achievable upon acute capsaicin treatment. WebWhereas phenyldiguanide has little activity in the dog, lobeline is equi-potent in the dog and cat. It is proposed that lobeline in small doses stimulates sensory receptors in the pulmonary circulation that are pharmacologically and possibly anatomically distinct from those for the amidines and veratridine. It also stimulates receptors that are ...
