RT Journal Article SR Electronic T1 ON THE ABSORPTION OF LOCAL ANESTHETICS THROUGH THE GENITO-URINARY ORGANS JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 435 OP 448 VO 16 IS 6 A1 DAVID I. MACHT YR 1921 UL http://jpet.aspetjournals.org/content/16/6/435.abstract AB 1. The local anesthetics, cocain, alypin and apothesin, were studied in regard to their penetration through and absorption from various genito-urinary organs. 2. It was found that these drugs are more or less readily absorbed through the urethra, ureters, pelvis of the kidney, praeputium and vagina. 3. It was found that while the local anesthetics are readily and rapidly absorbed from the urethra, they are very poorly absorbed from the urinary bladder.
