PYRROBUTAMINE is a potent H1-antihistamine. H1-antihistamines interfere with the agonist action of histamine at the H1 receptor and are administered to attenuate the inflammatory process in order to treat conditions such as allergic rhinitis, allergic conjunctivitis, and urticaria.

Dimoxyline is the synthetic analogue of papaverine, Acute toxicity studies show it to be less toxic than papaverine. No analgesic action and no tolerance development in experimental animals by repeated administration. But Dimoxyline does not appear to be as potent as papaverine in comparable dosage. Dimoxyline is indicated for the treatment of patients with angina pectoris. Also, significant amount of benefit was claimed in patients with acute or chronic phlebitis, arterial thrombosis or embolism, Raynaud’s phenomena and early thromboangiitis obliterans or arteriosclerosis obliterans. Detected adverse events are: nausea or abdominal cramps.

Diethanolamine (DEA) is an amino alcohol commonly used in the preparation of soaps and surfactants, agricultural chemicals and in textile processing. DEA and DEA-Derivatives are used in other products besides cosmetics and personal care products. For example, DEA and DEA-derivatives have been approved for several food-related applications, primarily food packaging.

Adenosine monophosphate (AMP) is a nucleotide, consisting of a phosphate group, the sugar ribose, and the nucleobase adenine. AMP is an activator of several enzymes in the tissues. In the glycolytic pathway, the enzyme phosphofructokinase is inhibited by ATP but the inhibition is reversed by AMP, the deciding factor for the reaction being the ratio between ATP and AMP. In medicine, AMP is used mainly as an alternative to adenosine for treatment of ischemia and as a tool compound to measure hyperresponsiveness of airways.

Pentaquine is an 8-aminoquinoline that was used in the 1950s to treat malaria and trypanosomiasis. Pentaquine showed no significant sporontocidal activity against P. gallinaceum in Aedes aegypti. In the experimental animals, the antimalarial effect of pentaquine, its pharmacology and toxicology have been investigated (1, 2). Activity, 80 to 128 times that of quinine and two to eight times that of pamaquin in avian malaria. It has adverse effects very similar to those of primaquine. In mammals it is rapidly absorbed from the gastro-intestinal tract. In acute, and in short term chronic toxicity studies, pentaquine was from one-fourth to one-half as toxic as pamaquin. In the dog, pamaquin in large doses produces severe anorexia, emaciation and ocular paralysis due to central impairment of the sympathetic innervation of the eye. In high dosages pamaquin produces leukopenia, neutropenia, anemia, methemoglobinemia, emaciation, depression, and liver damage in the monkey, effects which are not produced with pentaquine in this species.

Antazoline is an antagonist of histamine H1 receptors. It selectively bind to but does not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine. Antazoline in combination with naphazoline (VASOCON-A®) is indicated to relieve the symptoms of allergic conjunctivitis.

Octodrine is a stimulant that is structurally similar to amphetamine and is included in several so-called “pre-workout” and “fat-burning” supplements. Octodrine, has a history of use as a pharmaceutical drug. It was originally developed in the United States as an aerosolized treatment for bronchitis, laryngitis and other conditions Initially approved by the FDA in 1946 as Eskay’s Oralator, this inhaler appeared only in the 1949 edition of the Physicians’ Desk Reference. Octodrine was combined with several other medications, including theophylline, 3-octopamine, and adenosine, in multi-ingredient tablets sold between the early 1960s through the mid-2000s under the trade names Ambredin, Ordinal, Ordinal Retard and Ordinal Forte. Some proponents say octodrine is a safer alternative to other stimulants like ephedra and Dimethylamylamine (DMAA), but there is no scientific information to support this claim. Originally developed in the early 1950’s as a remedy to nasal congestion and as a possible anti-tumor drug, Octodrine has resurfaced as a key ingredient in dietary supplements for its stimulant and thermogenic benefits.

Cerous iodide is a salt of lanthanide metal cerium (III) and iodide ion. In 1920s solution of cerous iodide for intravenous injection (called "introcid") was used as an antimicrobial agent for treating puerperal fever. It has shown prophylactic activity against sepsis, and was explored for its antineoplastic properties in patients with lymphogranulomatosis or inoperable solid tumors. According to the clinical reports, it has been applied with remarkable benefit, as indicated by tumor shrinkage and improved quality of life in several cases of locally advanced or metastatic tumors of different origin.

Silver iodide is an inorganic compound with the formula AgI. It is used as a photosensitive agent in photography, as a local antiseptic, as a chemical intermediate, and in cloud seeding for rain-making. The major hazards encountered in the use and handling of silver iodide stem from its toxicologic properties. Effects from exposure may include skin rashes, conjunctivitis, argyria (a permanent ashen-gray discoloration of skin, conjunctiva, and internal organs), headache, fever, hypersensitivity, laryngitis, and bronchitis.

Hesperidin is a flavanone glycoside found in citrus fruits. Its aglycone form is called hesperetin. Its name is derived from the word "hesperidium", for fruit produced by citrus trees. Hesperidin was first isolated in 1828 by French chemist Lebreton from the white inner layer of citrus peels (mesocarp, albedo). As a flavanone found in citrus fruits (such as oranges, lemons or pummelo fruits), hesperidin is under laboratory research for possible biological properties. One area of research is focused on the possible chemopreventive effects of hesperidin, but there is no current proof that hesperidin has this role in human cancer mechanisms. Hesperidin was effective in an animal model of Alzheimer's, alleviating pathological changes induced by aluminum. Early research suggests that taking one tablet of a specific product (Daflon 500, Les Laboratoires Servier) containing hesperidin and diosmin by mouth for 45 days decreases blood sugar levels and improves blood sugarcontrol in women with type 2 diabetes. For Rheumatoid arthritis (RA): early research suggests that drinking a beverage containing alpha-glucosyl hesperidin for 12 weeks improves symptoms of RA. Orally, hesperidin can cause gastrointestinal side effects, including abdominal pain, diarrhea, and gastritis. Headache can also occur in some patients. The possible anti-inflammatory action of hesperidin is probably due to the possible anti-inflammatory action of its aglycone hesperetin. Hesperetin appears to interfere with the metabolism of arachidonic acid as well as with histamine release. Hesperetin appears to inhibit phospholipase A2, lipoxygenase and cyclo-oxygenase. There is evidence that hesperetin inhibits histamine release from mast cells, which would account for the possible anti-allergic activity of hesperidin. The possible hypolipidemic effect of hesperidin is probably due to hesperetin's possible action in lipid lowering. Hesperetin may reduce plasma cholesterol levels by inhibition of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, as well as acyl coenzyme A: cholesterol acytransferase (ACAT). Inhibition of these enzymes by hesperetin has been demonstrated in rats fed a high cholesterol diet. The mechanism of hesperidin's possible vasoprotective action is unclear. Animal studies have shown that hesperidin decreases microvascular permeability. Hesperidin, itself or via hesperetin, may protect endothelial cells from hypoxia by stimulating certain mitochondrial enzymes, such as succinate dehydrogenase. The mechanism of hesperidin's possible anticarcinogenic action is also unclear. One explanation may be the inhibition of polyamine synthesis. Inhibition of lipoxygenase and cyclo-oxygenase is another possibility.
