Anti-inflammatory action of drugs that raise adenosine-3',5'-cyclic monophosphate and putrescine levels in-vivo.

Isoprenaline and salbutamol, two beta-adrenoceptor agonist drugs, and 3-isobutyl-methyl xanthine and thioacetamide have been shown to be anti-inflammatory. Their mode of action is probably due to an increase in the levels of the three endogenous substances adenosine-3',5'-cyclic monophosphate and putrescine and spermidine in-vivo.
