Axitirome (also known as CGS 26214), a thyroid hormone receptor β selective agonist and an LDL receptor function stimulant, has a cholesterol-lowering activity. This drug was in phase I clinical trials for the treatment of hyperlipidemia, but studies were discontinued because of the unexpected side effects.

Tropodifene (Tropaphen) is an α-Adrenergic receptor blocking agent. Clinical trials have shown that tropaphen has a beneficial effect on hypertension. Tropaphen has a very marked adrenolytic and vasodilator action. It greatly lowers the tone of the peripheral vessels. The preparation is effective starting with a dose of 0.1 mg/kg. After injection of the drug in a dose of 0.25 mg/kg, a considerable and gradually progressive decrease in the perfusion pressure takes place. The pressure falls by 30-35% and remained at a low level for 90-100 min. With a dose of tropaphen of 0.5 mg/kg, the perfusion pressure falls by 40-45% and remains low for 120 min or more. Strong vasodilatation is also observed after injection of tropaphen into intact rabbits.

Terciprazine was developed as an antihypertensive agent that has never been marketed. Information about the current use of this drug is not available.

Dezinamide is a potential antiepileptic drug that binds to the voltage-sensitive sodium channel. It is a metabolite of fluzinamide. It was active in preventing maximal seizures induced in mice or rats by electroshock and threshold seizures induced in mice by metrazol, bicuculline, and picrotoxin. It was predominantly active against tonic-clonic seizures. Adverse experiences included headache, ataxia, blurred vision, diplopia, dizziness, lightheadedness, and mild confusion. Dezinamide development was discontinued because of toxicity problems not observed with the metabolite.

FLOSATIDIL is an antihypertensive drug discontinued in Phase II for angina pectoris.

Fluperamide was developed as an antiperistaltic agent for the treatment of diarrhea. However, information about the current use of the drug is not available.
