THALLOUS OXIDE (Thallium (1) Oxide) has been used in the manufacturing of glass of a high coefficient of refraction for optical purposes (thallium flint glass) and for artificial gems. Thallium oxide is black in color and is the inorganic compound of Thallium and Oxygen. THALLOUS OXIDE compounds are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics (e.g. tablets) and in light weight structural components in aerospace and electrochemical applications such as fuel cells. THALLOUS OXIDE is toxic by ingestion. It has previously been used as rat poison and ant killer, but its use is prohibited since 1972.

Pizotifen (INN) or pizotyline (USAN), trade name Sandomigran, is a benzocycloheptene-based drug used as a medicine, primarily as a preventative to reduce the frequency of recurrent migraine headaches. Pizotifen is a serotonin antagonist acting mainly at the 5-HT2A and 5HT2C receptors. It also has some activity as an antihistamine as well as some anticholinergic activity. The main medical use for pizotifen is for the prevention of vascular headache including migraine and cluster headache. Pizotifen is one of a range of medications used for this purpose, other options include propranolol, topiramate, valproic acid and amitriptyline. While pizotifen is reasonably effective, its use is limited by side effects, principally drowsiness and weight gain, and it is usually not the first choice medicine for preventing migraines, instead being used as an alternative when other drugs have failed to be effective. It is not effective in relieving migraine attacks once in progress. Pizotifen has also been reported as highly effective in a severe case of erythromelalgia, a rare neurovascular disease that is sometimes refractory to the other drugs named above. Side effects include sedation, dry mouth, drowsiness, increased appetite and weight gain. Occasionally it may cause nausea, headaches, or dizziness. In rare cases, anxiety, aggression and depression may also occur. Pizotifen is well absorbed from the gastro-intestinal tract, peak plasma concentrations occurring approximately 5 hours after oral administration. The absorption of pizotifen is fast (absorption half life 0.5 to 0.8 hours) and nearly complete (80%). Over 90% is bound to plasma proteins. Pizotifen undergoes extensive metabolism. Over half of a dose is excreted in the urine, chiefly as metabolites; a significant proportion is excreted in the faeces. The primary metabolite of pizotifen (N-glucuronide conjugate) has a long elimination half-life of about 23 hours.

Balofloxacin (Q-35), is an orally active fluoroquinolone antibiotic. It has been developed for the treatment of urinary tract infection. The bactericidal action of Balofloxacin results from interference with the enqyme DNA gyrase which is needed for the synthesis of bacterial DNA. Balofloxacin is efficacious against Gram-negative bacteria. It also has enhanced activity against Gram positive bacteria, including MRSA and Streptococcus pneumoniae. Side effects of Balofloxacin are: sensitivity to light, abdominal pain, nausea, heartburn, urticarial, irritation when applied locally. Balofloxacin may interact with the following medicines and salts: antacids, non-steroidal anti-inflammatory drug, quinolones, theophylline.

Kainic acid (kainate) is a natural marine acid present in some seaweed. Kainic acid is a potent neuroexcitatory amino acid that acts by activating receptors for glutamate, the principal excitatory neurotransmitter in the central nervous system. Kainic acid is commonly injected into laboratory animal models to study the effects of experimental ablation. Kainic acid is a direct agonist of the glutamic kainate receptors and large doses of concentrated solutions produce immediate neuronal death by overstimulating neurons to death. Such damage and death of neurons is referred to as an excitotoxic lesion. Thus, in large, concentrated doses kainic acid can be considered a neurotoxin, and in small doses of dilute solution kainic acid will chemically stimulate neurons. Kainic acid is utilised in primary neuronal cell cultures and acute brain slice preparations [5] to study of the physiological effect of excitotoxicity and assess the neuroprotective capabilities of potential therapeutics. Kainic acid is a potent central nervous system excitant that is used in epilepsy research to induce seizures in experimental animals, at a typical dose of 10–30 mg/kg in mice. In addition to inducing seizures, kainic acid is excitotoxic and epileptogenic. Kainic acid induces seizures via activation of kainate receptors containing the GluK2 subunit and also through activation of AMPA receptors, for which it serves as a partial agonist.

DODICIN (Tego-51), one of the amphoteric surfactants based on the dodecyl-di( aminoethyl)-glycine, has been considered as an effctive disinfectant having a broad specturn of antimicrobial activity. Tego-51 disinfectant was effective for the disinfection of commonly isolated bacteria and yeast from hospital. It may be recommended that Tego-51 should be used at concentration greater than 0.1% for the effective disinfection of skin, instruments and hospital floors.

Cadrofloxacin hydrochloride was studied for the treatment of bacterial infections. The compound was originally developed by UBE and Daiichi Sankyo. However, this study was discontinued. The compound currently was developed by Hengrui. Cadrofloxacin showed potent bactericidal activity against S. aureus, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa.

Laninamivir ocatanoate is a prodrug of Laninamivir (R-125489), a new neuraminidase (NA) inhibitor, was discovered, and in this study, its NA inhibitory activities against various influenza viruses including oseltamivir-resistant viruses are reported. Laninamivir octanoate has been approved for use in Japanese clinics for the treatment and prevention of influenza in both adults and children. The inhaled laninamivir octanoate is converted into its active form, laninamivir, in the lungs where a high concentration persists for a long period of time.

Ethamsylate (2,5-dihydroxy-benzene-sulfonate diethylammonium salt) is a synthetic hemostatic drug indicated in cases of capillary bleeding. Ethamsylate acts on the first step of hemostasis by improving platelet adhesiveness and restoring capillary resistance. In addition it inhibits prostaglandin biosynthesis. Well-controlled clinical trials clearly showed the therapeutic efficacy of ethamsylate in dysfunctional uterine bleeding, with the magnitude of blood-loss reduction being directly proportional to the severity of the menorrhagia. Other well-controlled clinical trials showed therapeutic efficacy of ethamsylate in periventricular hemorrhage in very low birth weight babies and surgical or postsurgical capillary bleeding.

Cefteram is a semisynthetic cephalosporin formulated for oral administration as the prodrug ester, cefteram pivoxil. The mechanism of action of cefteram is inhibition of bacterial cell wall synthesis. Cefteram exerts its bactericidal activity by strongly binding to penicillin-binding protein (PBP) 3, 1A, and 1Bs. The drug is available in Japan and is used for the treatment of bacterial infections.

Zabicipril is an ethyl ester prodrug that is converted in vivo to zabiciprilat. Zabicipril induced an early, potent, and long-lasting converting enzyme inhibition. Furthermore, zabicipril did not affect plasma catecholamines and atrial natriuretic factor. It is antihypertensive and peripheral vasodilator. In normal men, zabicipril increases the renal fraction of cardiac output in the absence of a concomitant change in systemic haemodynamics. This specific effect of zabicipril on the kidney may be less important with advancing age.
