tetraethylammonium + quinine + tolbutamide

This is a combination of three small molecule drugs: - **Tetraethylammonium** is a quaternary ammonium compound primarily used as an experimental pharmacological agent. It acts as a non-selective blocker of various potassium channels, blocks autonomic ganglia, and inhibits nicotinic acetylcholine receptors. Historically, it was investigated for use as a vasodilator and in neurological conditions but is not approved for any indication due to toxicity concerns[1][2][4]. - **Quinine** is an alkaloid with antimalarial properties that also has activity as a sodium channel blocker and can affect cardiac conduction. - **Tolbutamide** is an oral first-generation sulfonylurea antidiabetic agent used to lower blood glucose in type 2 diabetes mellitus by stimulating insulin release from pancreatic β-cells[7][10]. No evidence was found that this specific triple combination (tetraethylammonium + quinine + tolbutamide) has been developed or marketed under any brand or code name. Each component has distinct mechanisms of action.
