Actions of prostaglandins on the respiratory tract of animals.

Abstract

Experimental data now strongly suggest that the PGs, by nature of their natural local occurrence and destruction, powerful effects on, and release from lung tissue are important in regulating both pulmonary homeostasis and dysfunction. Laboratory studies on their activity, potency, duration, preferred route of administration, mechanism and possible antiallergic effects, have been largely substantiated in humans. Structure activity studies on a large number of congeners of PGE, PGF, and PGA emphasize the critical importance of stereochemistry and various substituent groups on biologic activity in the lung.
