Starch, corn
|
DB11599 |
[Corn starch refers to the starch extracted from the corn grain that is commonly used as a food ingredient and chemical additive. Starch is any of a group of polysaccharides of the general formula (C6-H10-O5)n, composed of a long-chain polymer of glucose in the form of amylose and amylopectin. Starch is the chief storage form of energy reserve (carbohydrates) in plants. Corn starch may be added in some food products as a thickening agent or anti-caking agent, and is sometimes found in topical drugs as a skin protectant.] |

Human Rho(D) immune globulin
|
DB11597 |
[Human Rho(D) immune globulin is a medicine given by intramuscular or intravenous injection that is used to prevent the immunological condition known as Rh disease (or hemolytic disease of newborn). Rho (D) immune globulin is available as a sterile, lyophilized or liquid gamma globulin (IgG) fraction containing antibodies to the Rh0 (D) antigen (D antigen) under the name Rhophylac (IM/IV). Immune globullin was purified via ion-exchange chromatography method and prepared from pools of human plasma, where the donors are Rho (D)-negative donors who have been immunized with Rho(D)-positive RBCs. It was approved by FDA as treatment for suppression of rhesus (Rh) isoimmunization or chronic immune thrombocytopenic purpura (ITP) in adults.] |

Levoleucovorin
|
DB11596 |
[Levoleucovorin is the enantiomerically active form of Folinic Acid (also known as 5-formyl tetrahydrofolic acid or leucovorin). Commercially available leucovorin is composed of a 1:1 racemic mixture of the dextrorotary and levorotary isomers, while levoleucovorin contains only the pharmacologically active levo-isomer. In vitro, the levo-isomer has been shown to be rapidly converted to the biologically available methyl-tetrahydrofolate form while the dextro form is slowly excreted by the kidneys. Despite this difference in activity, the two commercially available forms have been shown to be pharmacokinetically identical and may be used interchangeably with limited differences in efficacy or side effects (Kovoor et al, 2009).
As folate analogs, levoleucovorin and leucovorin are both used to counteract the toxic effects of folic acid antagonists, such as methotrexate, which act by inhibiting the enzyme dihydrofolate reductase (DHFR). They are indicated for use as rescue therapy following use of high-dose methotrexate in the treatment of osteosarcoma or for diminishing the toxicity associated with inadvertent overdosage of folic acid antagonists. Levoleucovorin, as the product Fusilev (FDA), has an additional indication for use in combination chemotherapy with 5-fluorouracil in the palliative treatment of patients with advanced metastatic colorectal cancer.
Folic acid is an essential B vitamin required by the body for the synthesis of purines, pyrimidines, and methionine before incorporation into DNA or protein. However, in order to function in this role, it must first be reduced by the enzyme dihydrofolate reductase (DHFR) into the cofactors dihydrofolate (DHF) and tetrahydrofolate (THF). This important pathway, which is required for de novo synthesis of nucleic acids and amino acids, is disrupted when high-dose methotrexate is used for cancer therapy. As methotrexate functions as a DHFR inhibitor to prevent DNA synthesis in rapidly dividing cells, it also prevents the formation of DHF and THF. This results in a deficiency of coenzymes and a resultant buildup of toxic substances that are responsible for numerous adverse side effects of methotrexate therapy. As levoleucovorin and leucovorin are analogs of tetrahydrofolate (THF), they are able to bypass DHFR reduction and act as a cellular replacement for the co-factor THF, thereby preventing these toxic side effects.] |

Thimerosal
|
DB11590 |
[Thiomersal (INN), commonly known in the U.S. as thimerosal, is an organomercury compound. This compound is a well-established and widely used antiseptic and antifungal agent.
Developed in 1927, thimerosal has been and is still being used as a preservative in some cosmetics, topical pharmaceuticals, and biological drug products, which includes vaccines. There has been significant concern regarding its safety and toxicity in the last several decades. Although thimerosal is banned in several countries, it continues to be included as a preservative in some vaccines in the United States and many vaccines in the developing world [L1685].] |

Ubidecarenone
|
DB09270 |
[Ubidecarenone, also called coenzyme Q10, is a 1,4-benzoquinone. From his name (Q10), the Q refers to the constitutive quinone group, and 10 is related to the number of isoprenyl subunits in its tail.[A7874] It is a powerful antioxidant, a lipid-soluble and essential cofactor in mitochondrial oxidative phosphorylation.[A31413] The ubidecarenone is the coenzyme destined for mitochondrial enzyme complexes involved in oxidative phosphorylation in the production of ATP. It is fundamental for cells that have a high metabolic demand.[L1062] Ubidecarenone is sold as a dietary supplement and is not FDA approved as a drug thus, it is not meant to treat, cure or prevent any disease. FDA does not approve this dietary supplements before sold nor regulate the manufacturing process.[L1063]] |

Doxofylline
|
DB09273 |
[Doxofylline is a methylxanthine derivative with the presence of a dioxolane group in position 7. As a drug used in the treatment of asthma, doxofylline has shown similar efficacy to theophylline but with significantly fewer side effects in animal and human studies. In contrast with other xanthine derivatives, doxofylline does not significantly bind to adenosine alpha-1 or alpha-2 receptors and lacks stimulating effects. Decreased affinity for adenosine receptors may account for the better safety profile of doxofylline compared to theophylline [L1169]. Unlike theophylline, doxofylline does not affect calcium influx and does not antagonize the actions of calcium channel blockers which could explain reduced cardiac adverse reactions associated with the drug [A7885]. The anti-asthmatic effects of doxophylline are mediated by other mechanisms, primarily through inhibiting the activities of the phosphodiesterase (PDE) enzyme.] |

Eluxadoline
|
DB09272 |
[Eluxadoline is a mixed mu-opioid receptor agonist, kappa-opioid receptor agonist, and a-delta opioid receptor antagonist indicated for use in diarrhea-predominant irritable bowel syndrome (IBS-D). The mu-, kappa-, and delta-opioid receptors mediate endogenous and exogenous opioid response in the central nervous system and peripherally in the gastrointestinal system. Agonism of peripheral mu-opioid receptors results in reduced colonic motility, while antagonism of central delta-opioid receptors results in improved analgesia, making eluxadoline usable for the symptoms of both pain and diarrhea characteristic of IBS-D.
Marketed under the tradename Viberzi (FDA), eluxadoline is an antimotility agent that decreases bowel contractions, inhibits colonic transit, and reduces fluid/ion secretion resulting in improved symptoms of abdominal pain and reductions in the Bristol Stool Scale.] |

Activated charcoal
|
DB09278 |
[Activated charcoal, or activated carbon, is an amorphous form of carbon prepared from incomplete combustion of carbonaceous organic matter. It is activated by an oxidizing gas flow at high temperature passed over its surface to make a fine network of pores, producing a material with large surface area and high affinity for various substances. It is used as a gastric decontaminant and emergency medication to treat poisonings following excessive oral ingestion of certain medications or poisons by absorbing most drugs and toxins. However its effects is rendered poor on some compounds including strong acids or bases, methanol and substances with limited absorptive capacity (including iron, lithium, arsenic). It works by binding to the poison in the gastric contents in a reversible fashion thus may be adminstered together with a cathartic to reduce the small intestine transit time. The clinical applications of activated charcoal occured in the early 1800's. While this management for acute poisoning is considered fairly invasive, it is on the World Health Organization's List of Essential Medicines that includes the most important medications needed in a basic health system.] |
