The in vivo biodistribution for (N-methyl[11C])pyrilamine in mice is reported for various times after i.v. bolus injection, together with estimates of the radiation absorbed dose for the same radiotracer in man. More than 60% of the injected dose was excreted via the kidneys in urine after 90 min post injection. The brain regional distribution in mice showed a favorable hypothalamus-to-cerebellum ratio, indicative of H-1 receptor binding, encouraging in vivo histamine H-1 receptor imaging studies in man.
