Conditions:
Thimerosal is organomercury antiseptic and antifungal agent, used as a preservative in vaccines, immuloglobulins, nasal sprays, contact lens solutions. In USA, European Union countries thiomersal is no longer used in childhood vaccines due to public fears, although the FDA review of 1999 foud no evidence of harm from the use of thimerosal as a vaccine preservative, other than local hypersensitivity reactions. Thimerosal was used as a component of topical antiseptic solution and antiseptic ointment for treating cuts, nasal sprays, eye solutions, vaginal spermicides, diaper rash treatments, but re-evaluation of the drug in 1980-s demonstrated ineffectiveness and toxicity in topical pharmaceutical products, and topical thimerosal was withdrawn from the market. The mechanism of action of thimerosal has not been fully elucidated. It is believed that thimerosal inhibits sulfhydryl-containing active site of various enzymes and binds to sulfhydryl compounds, such as glutathione, cysteine, and SH groups of protein. In addition, thimerosal activates the InsP3 calcium channel on endoplasmic reticular membrane, thereby triggering the release of calcium from intracellular stores resulting in a calcium-induced calcium-influx of extracellular calcium. Consequently, thimerosal may induce or inhibit cellular functions dependent on calcium signaling.

Conditions:
SODIUM GLYCOLATE, a sodium salt of carboxymethyl ether, is used as a pharmaceutical grade dissolution excipient for solid dosage forms. It absorbs water rapidly, resulting in swelling which leads to the rapid disintegration of tablets and capsules. Without a disintegrant, these may not dissolve appropriately and may effect the amount of active ingredient absorbed, thereby decreasing effectiveness.

Conditions:
Alverine is a smooth muscle relaxant used for the treatment irritable bowel syndrome. Alverine may increase calcium influx during action potentials due to inhibition of the inactivation of L-type calcium channels, but may also suppress evoked activity by inhibiting the sensitivity of contractile proteins to calcium.

Sulfoxone is a water-soluble sulfone and is a competitive inhibitor of the bacterial enzyme dihydropteroate synthetase. Sulfoxone under the brand name Diasone was used as an antileprosy drug, for treatment of dermatitis herpetiformis, and to treat pulmonary tuberculosis. Presently, usage of diasone has been discontinued.

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.

Conditions:
Methionine is an non-polar, aliphatic, essential α-amino acid that is used in the biosynthesis of proteins. High levels of methionine can be found in eggs, sesame seeds, Brazil nuts, fish, meats and some other plant seeds; methionine is also found in cereal grains. Most fruits and vegetables contain very little of it. Most legumes are also low in methionine. However, it is the combination of methionine and cystine which is considered for completeness of a protein. There is scientific evidence that restricting methionine consumption can increase lifespans in some animals. However, since methionine is an essential amino acid, it cannot be entirely removed from animals' diets without disease or death occurring over time. For example, rats fed a diet without methionine developed steatohepatitis (fatty liver), anemia and lost two thirds of their body weight over 5 weeks. Administration of methionine ameliorated the pathological consequences of methionine deprivation.
