Phosphoric acid, also known as orthophosphoric acid, is used in dentistry and orthodontics to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed. In addition, this acid is a part of product ProcalAmine, which is indicated for peripheral administration in adults to preserve body protein and improve nitrogen balance in well-nourished, mildly catabolic patients who require short-term parenteral nutrition. In combination with dextrose (glucose) and levulose (fructose), phosphoric acid relieves nausea due to upset stomach from intestinal flu, stomach flu, and food or drink indiscretions. In addition, homeopathic product, Brain power contains also phosphoric acid and this product is used to temporarily relieve symptoms of general physical weakness and listlessness, including: fatigue; sore muscles & joints; dry skin; absence of sexual desire; occasional sleeplessness.

Hydroxocobalamin (also hydroxycobalamin, OHCbl) is a natural form, or vitamer, of vitamin B12. It is a member of the cobalamin family of compounds. Hydroxocobalamin, the active ingredient in Cyanokit, is cobinamide dihydroxide dihydrogen phosphate (ester), mono (inner salt), 3’-ester with 5,6-dimethyl-1-α-D-ribofuranosyl-1H-benzimidazole. The drug substance is the hydroxylated active form of vitamin B12 and is a large molecule in which a trivalent cobalt ion is coordinated in four positions by a tetrapyrol (or corrin) ring. It is a hygroscopic, odorless, dark red, crystalline powder that is freely soluble in water and ethanol, and practically insoluble in acetone and diethyl ether. Cyanokit contains hydroxocobalamin, an antidote indicated for the treatment of known or suspected cyanide poisoning. Cyanide is an extremely toxic poison. In the absence of rapid and adequate treatment, exposure to a high dose of cyanide can result in death within minutes due to the inhibition of cytochrome oxidase resulting in arrest of cellular respiration. Specifically, cyanide binds rapidly with cytochrome a3, a component of the cytochrome c oxidase complex in mitochondria. Inhibition of cytochrome a3 prevents the cell from using oxygen and forces anaerobic metabolism, resulting in lactate production, cellular hypoxia and metabolic acidosis. In massive acute cyanide poisoning, the mechanism of toxicity may involve other enzyme systems as well. Signs and symptoms of acute systemic cyanide poisoning may develop rapidly within minutes, depending on the route and extent of cyanide exposure. The action of Cyanokit is based on its ability to bind cyanide ions. Each hydroxocobalamin molecule can bind one cyanide ion by substituting it for the hydroxo ligand linked to the trivalent cobalt ion, to form cyanocobalamin, which is then excreted in the urine.

Synthetic glycerophosphates have been known for many years and have been prepared in several ways. The acid may exist in two isomeric forms, alpha and beta. The L-a-acid is the naturally occurring form; the b-acid, present in hydrolyzates of lecithins from natural sources, arises from migration of the phosphoryl group from the a-carbon atom. Dehydrogenation of L-glycerol 3-phosphate produces Dihydroxyacetone phosphate and is part of the entry of glycerol (sourced from triglycerides) into the glycolytic pathway.

Morphine is one of the most important and widely used opioid for the treatment of chronic and acute pain: the very wide interindividual variability in the patients’ response to the drug may have genetic derivations. Sulphate salt of morphine sold under the many brand names, one of them, DURAMORPH, which is indicated for the management of pain severe enough to require use of an opioid analgesic by intravenous administration, and for which alternative treatments are not expected to be adequate. In addition for the epidural or intrathecal management of pain without attendant loss of motor, sensory, or sympathetic function. Morphine is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of morphine is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with morphine. The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug. Morphine has a high potential for addiction and abuse. Common side effects include drowsiness, vomiting, and constipation. Caution is advised when used during pregnancy or breast-feeding, as morphine will affect the baby.

Discovered as natural products from actinomycetes soil bacteria, the tetracyclines were first reported in the scientific literature in 1948. They were noted for their broad spectrum antibacterial activity and were commercialized with clinical success beginning in the late 1940s to the early 1950s. By catalytic hydrogenation of Aureomycin, using palladium metal and hydrogen, the C7 deschloro derivative was synthesized, producing a compound of higher potency, a better solubility profile, and favorable pharmacological activity; it was subsequently named tetracycline. Tetracyclines are primarily bacteriostatic and exert their antimicrobial effect by the inhibition of protein synthesis by binding to the 30S ribosomal subunit. Tetracycline is active against a broad range of gram-negative and gram-positive organisms. Tetracycline is indicated in the treatment of infections caused by susceptible strains. To reduce the development of drug-resistant bacteria and maintain the effectiveness of tetracycline hydrochloride and other antibacterial drugs, tetracycline hydrochloride should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.

Kasal (Sodium Aluminum Phosphate, basic, non-leavening) is a white odorless powder comprised of an autogenous mixture of alkaline sodium aluminum phosphate and dibasic sodium phosphate. Kasal is used primarily as an emulsifier in the production of processed cheese.

Amiselimod (MT-1303) is a selective sphingosine 1-phosphate 1 (S1P1 ) receptor modulator which is currently being developed for the treatment of various autoimmune diseases. Unlike some other S1P receptor modulators, amiselimod seemed to show a favourable cardiac safety profile in preclinical, phase I and II studies. Amiselimod may be potentially useful for treatment of multiple sclerosis; inflammatory diseases; autoimmune diseases; psoriasis and inflammatory bowel diseases. Amiselimod is currently being developed by Mitsubishi Tanabe Pharma Corporation.

Fosquidone (also known as GR63178A), a pentacyclic pyrroloquinone that was developed as an anticancer agent. Fosquidone participated in phase II clinical trial for the treatment of patients with colorectal, renal and non-small cell lung cancer. However, the drug didn’t show significant antitumor activity. The further development of this drug was discontinued.

Fospirate is an organophosphorus insecticide used in veterinary as an anthelmintic agent.
