The Canada-pitch plaster (Emplastrum PicisCanadensis) is employed for the same conditions as the plaster ofBurgundy pitch. PITUITARY GLAND. The posterior lobe (infundibulum) of the pituitary gland is nowlargely used in medicine. In dried form it is official in the U. S. Hypophysis Sicca, and a liquid extract is also official as LiquorHyphophysis, U. S. The preparation in liquid form most generallyused for all purposes is called pituitrin. The physiological action of this substance when given intraven-ously is almost identical with adrenalin in that it is a stimulant tothe muscular coats of the bloodvessels, but its action, althoughmore prolonged than that of adrenalin, is less powerful andless sudden in onset. It slows the pulse-rate. Locally applied to PITUITARY GLAND 449. o . to 29 450 DRUGS mucous membranes it induces a similar ischemia to that caused byadrenalin.

It increases urinary flow,not by stimulating the epithelium of the kidney, but by increasingthe blood-pressure in the renal vessels. It also in some cases increasesthe secretion of milk. Therapeutics.—Pituitrin for the reasons just given finds its chiefuse as an oxytoxic which is not to be given until the os is dilated tothe size of a quarter of a dollar and until the physician is sure thatthe birth canal is not obstructed. Its action is so prompt that afterit is given the physician should not leave the patient.
