The relationship between bovine tracheal muscle contraction and phosphoinositide metabolism was studied with the muscarinic agonists, methacholine, oxotremorine, and McN-A-343. Analysis of the dose-response curves for contraction and inositol phosphates accumulation with these agonists demonstrated a direct relationship between the two parameters, with a considerable reserve of inositol phosphate production for the full contractile agonists, methacholine and oxotremorine, and no reserve for the partial agonist, McN-A-343.
