Iodide I-131 (as Sodium iodide I-131) is a radioisotopic drug used for the treatment and palliation of thyroid malignancy. Iodine-131 is notable for causing mutation and death in cells that it penetrates, which is due to its mode of beta decay. Iodide I-131 can be detected by gamma cameras for diagnostic imaging, however, it is rarely administered for diagnostic purposes only, imaging will normally be done following a therapeutic dose. Major uses of 131I include the treatment of thyrotoxicosis (hyperthyroidism) due to Graves' disease, and sometimes hyperactive thyroid nodules (abnormally active thyroid tissue that is not malignant). Iodine-131, in higher doses than for thyrotoxicosis, is used for ablation of remnant thyroid tissue following a complete thyroidectomy to treat thyroid cancer. The 131I isotope is also used as a radioactive label for certain radiopharmaceuticals that can be used for therapy, e.g. 131I-metaiodobenzylguanidine for imaging and treating pheochromocytoma and neuroblastoma. Because of the carcinogenicity of its beta radiation in the thyroid in small doses, I-131 is rarely used primarily or solely for diagnosis. Instead, the more purely gamma-emitting radioiodine iodine-123 is used in diagnostic testing. The longer half-lived iodine-125 is also occasionally used when a longer half-life radioiodine is needed for diagnosis, and in brachytherapy treatment, where the low-energy gamma radiation without a beta component makes iodine-125 useful.

Dimoxamine is a memory adjuvant. Dimoxamine hydrochloride has been reported to facilitate the performance of naive rats in a massed trial shuttle box task. At doses that facilitated shuttle box responding, dimoxamine had no effect on unacclimated motor activity of rats nor on the rate of continuous avoidance responding by rats. Dimoxamine has a psychopharmacological profile that is different from other phenylalkylamines such as S-amphetamine and R-DOM. Dimoxamine may prove beneficial in the treatment of individuals having low or deteriorated levels of certain types of associative and psychomotor abilities. Dimoxamine substituted completely for LSD. Dimoxamine can be classified as a partial agonist of 5-HT receptors in sheep umbilical arteries.

There is no much available information related to the biological and pharmacological application of imidoline, but this compound has been found to be as potent as chlorpromazine in increasing striatal DOPA accumulation and prolactin secretion in vivo. Imidoline exhibited only weak inhibitory activity towards dopamine-sensitive adenylate cyclase and 3H-spiroperidol binding to striatal membranes in vitro. A proposed active conformation involves intramolecular hydrogen bonding between the protonated dimethylamino group and the oxygen of the imidazolidinone ring. The spatial relationship between the amine nitrogen and phenyl ring in this conformation allows proper fit of imidoline with key dimensions described for the dopamine receptor.

Mazapertine (RWJ-37796) is an arylpiperazine antipsychotic with high affinity to dopamine D2 and D3, serotonin 5-HT1A and alpha 1A-adrenergic receptors. It was being studied in the treatment of schizophrenia.

Furosemide is a non-antibiotic bacterial urease inhibitor that can be used in the control of H. pylori-associated gastroduodenal disease.

Idrapril is an inhibitor of the angiotensin-converting enzyme the last is responsible for recurrent myocardial infarction in patients with left ventricular dysfunction. Idrapril participated in phase II clinical trials in essential hypertensive patients, where was shown that the drug was well tolerated. In addition, it was involved in preclinical studies as a potential drug to treat heart failure and postmyocardial infarction. However, the development of the drug was discontinued.

Carcainium is phenylcarbamoylmethyl derivative with local anesthetic and potent anti-tussive activity. In preclinical studies Carcainium significantly reduced the spontaneous and histamine-evoked discharges in Aδ-fibres originating from airway, rapidly adapting stretch receptors (RARs) without affecting histamine-evoked bronchoconstriction. Acute pre-treatment of guinea-pigs with aerosols of Carcainium prevent of capsaicin-evoked and citric acid-induced coughs.

Cefmepidium is a semisynthetic cephalosporin with broad antibacterial activity against penicillin-resistant strains.

Butopyrammonium is organic cationic compound.

Benzindopyrine belongs to anticholinergic agents. It was studied as an antipsychotic drug.
