RT Journal Article SR Electronic T1 SPECIFIC BLOCKADE OF THE ADRENAL MEDULLA JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 340 OP 345 VO 130 IS 3 A1 Gardier, Robert W. A1 Abreu, Benedict E. A1 Richards, Alice B. A1 Herrlich, Herman C. YR 1960 UL http://jpet.aspetjournals.org/content/130/3/340.abstract AB N,N-diisopropyl- N'-isoamyl-N'-diethylaminoethylurea (P-286) reverses the pressor response to acetyicholine in the atropinized dog. This reversal is due to selective blockade of the action of acetyicholine in the adrenal medulla. P-286 possesses a transient vasodepressor action per se, has weak ganglionic blocking action, and is not an adrenergic blocking agent.
