[The influence of pipemidic acid on epinephrine and collagen induced platelet aggregation in vitro]. 1985

H D Reuter, and S Thiele

Concentrations of pipemidic acid (Deblaston) similar to maximal levels obtained in the serum of patients with intact renal function after application of therapeutic doses do not influence epinephrine (adrenaline)- or collagen-induced aggregation in vitro. With 20 micrograms/ml pipemidic acid, corresponding 4- to 5-fold maximal serum levels epinephrine-induced aggregation is reduced significantly, while aggregation by collagen is not affected. A significant reduction of epinephrine-induced aggregation as well as of collagen-induced aggregation is brought about only with doses of pipemidic acid as high as 100 micrograms/ml. But these changes still occur within the normal range. Therefore we conclude from our study, that platelet aggregation is not affected in a clinically relevant manner by pipemidic acid.

D010974	Platelet Aggregation	The attachment of PLATELETS to one another. This clumping together can be induced by a number of agents (e.g., THROMBIN; COLLAGEN) and is part of the mechanism leading to the formation of a THROMBUS.	Aggregation, Platelet
D003094	Collagen	A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of SKIN; CONNECTIVE TISSUE; and the organic substance of bones (BONE AND BONES) and teeth (TOOTH).

D004837	Epinephrine	The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.
