Tetraethylammonium is an experimental drug with no approved indication or marketed formulation. Tetraethylammonium blocks of apamin-sensitive and insensitive Ca2(+)-activated K+ channels. It is a weak agonist of the nicotinic receptor. Tetraethylammonium produces transient reductions in blood pressure. Tetraethylammonium hydroxide is used as a soluble source of hydroxide ions and in the synthesis of ionic organic compounds.

TEA is a weak agonist of the nicotinic receptor. No single-channel clusters were observed at concentrations as high as 5 mM TEA or in the presence of a mutation which selectively increases the efficacy of the receptor. When coapplied with 1 mM carbamylcholine (CCh), TEA decreased the effective opening rate demonstrating that it acts as a competitive antagonist of CCh-mediated activation. Kinetic analysis of currents elicited by CCh and TEA allowed an estimate of receptor affinity for TEA of about 1 mM, while an upper limit of 10 s-1 could be set for the wild-type channel-opening rate constant for receptors activated by TEA alone. At millimolar concentrations, TEA inhibited nicotinic receptor currents by depressing the single-channel amplitude. The effect had an IC50 of 2-3 mM, depending on the conditions of the experiment, and resembled a standard open-channel block.
