P-32 is a radioactive isotope of phosphorus with a half-life of 14.29 days. Radioactive decay of P-32 produces beta-particles (electrons) which are able to penetrate tissue at a range of 3-8 mm. Phosphate ion P-32 has many applications in medicine and biology. P32 sodium phosphate was approved by the FDA for the treatment of polycythemia vera, chronic myelocytic leukemia, and chronic lymphocytic leukemia. P32-phosphate may also be used in the palliative treatment of selected patients with multiple areas of skeletal metastases. As metabolic uptake of phosphorus is selectively increased in malignant tissues, P-32 was also used for cancer diagnostics.

Propoxyphene is a centrally acting opiate analgesic. Propoxyphene is an odorless, freely soluble in water, white crystalline powder with a bitter taste. In vitro studies demonstrated propoxyphene and the metabolite norpropoxyphene inhibit sodium channels (local anesthetic effect) with norpropoxyphene being approximately 2 fold more potent than propoxyphene and propoxyphene approximately 10 fold more potent than lidocaine. Propoxyphene and norpropoxyphene inhibit the voltage-gated potassium current carried by cardiac rapidly activating delayed rectifier (hERG) channels with approximately equal potency. It is unclear if the effects on ion channels occur within therapeutic dose range. Propoxyphene is indicated for the relief of mild to moderate pain.

LEVAMFETAMINE the levorotatory form of amphetamine. L-amphetamine, is a central nervous system (CNS) stimulant known to increase wakefulness and concentration in association with decreased appetite and fatigue. Pharmaceuticals that contain levoamphetamine are currently indicated and prescribed for the treatment of attention deficit hyperactivity disorder (ADHD), obesity, and narcolepsy in some countries. L-Amphetamine succinate was sold in Hungary between 1952 and 1955 under the brand name Cydril.

Aniledrine is a narcotic pain reliver. The drug was prescribed as an analgesic in anaesthesia (Leritine brand name), however, it is no longer available on the market. Although the exact mechanism is not fully understood, aniledrine appears to elicit its action by binding to endorphine receptors in CNS.

Ethoheptazine is an analgesic, which belongs to the proheptazine group. It was used either alone (Zactane trade name) or in combination with meprobamate and aspirin (Equagesic) for the pain relief in patients with headache or musculoskeletal disorders. Currently all mediactions containing ethoheptazine are withdrawn from the market. The exact target of ethoheptazine is unknow, but it is believed that it may have modulatory effect on opioid receptors.

Benactyzine, an anticholinergic drug, had been used as an antidepressant in the treatment of depression and associated anxiety. It is no longer used in medicine due to its ineffectiveness but is widely used in scientific research. Benactyzine is a muscarinic antagonist which also inhibits the nicotinic acetylcholine receptor.
Promazine (Sparine) is a phenothiazine neuroleptic used for short-term management of moderate to severe psychomotor agitation and treatment of agitation and restlessness in the elderly. Promazine is an antagonist at types 1, 2, and 4 dopamine receptors, 5-HT receptor types 2A and 2C, muscarinic receptors 1 through 5, alpha(1)-receptors, and histamine H1-receptors. Promazine's antipsychotic effect is due to antagonism at dopamine and serotonin type 2 receptors, with greater activity at serotonin 5-HT2 receptors than at dopamine type-2 receptors. This may explain the lack of extrapyramidal effects. Promazine does not appear to block dopamine within the tuberoinfundibular tract, explaining the lower incidence of hyperprolactinemia than with typical antipsychotic agents or risperidone. Antagonism at muscarinic receptors, H1-receptors, and alpha(1)-receptors also occurs with promazine. Promazine is not approved for human use in the United States. It is available in the US for veterinary use under the names Promazine and Tranquazine.

Conditions:

Docusate, also known as docusate salts or dioctyl sulfosuccinate, prevents/relieves dry hard stool and thus is used to treat constipation. Results usually occurs 1 to 3 days after the first dose. In North America, docusate and a stimulant laxative such as sennosides are commonly used in bowel treatment protocols associated with institutionalized elderly and oncology treatments. A paucity of evidence is available to support the use of the stool softener docusate yet it continues to be prescribed in everyday clinical practice for the aforementioned populations. While the actual cost of docusate is low, additional costs associated with its administration (i.e. nursing time) and its widespread use can be significant. Docusate is absorbed into the bloodstream and excreted via the gallbladder after undergoing extensive metabolism. The effect of docusate may not necessarily be all due to its surfactant properties. Perfusion studies suggest that docusate inhibits fluid absorption or stimulates secretion in the portion of the small intestine known as the jejunum
