This second neuron does not synapse with only a single cell in the effector organ; rather, it branches out, each branch making en passant contacts with several cells. At these junctions the nerve axons form enlargements (varicosities) resembling beads on a string.
Because this response is not immune mediated, such “pseudoallergic” reactions are a potential hazard with all NSAIDs. PG also regulate renal blood flow as functional antagonists of angiotensin II and norepinephrine. If release of the latter two is increased (e. g. , in hypovolemia), inhibition of PG production may result in reduced renal blood flow and renal impairment.

 

Due to their cationic amphiphilic nature, the TCA exert membrane-stabilizing effects that can lead to disturbances of cardiac impulse conduction with arrhythmias as well as decreases in myocardial contractility. All TCA lower the seizure threshold. Weight gain may result from a stimulant effect on appetite.

Fear of this situation would prompt intake of higher doses than necessary. Strictly speaking, the aim is a prophylactic analgesia.
