Maleic anhydride is used in the formulation of resins. Exposure to maleic anhydride may occur from accidental releases to the environment or in workplaces where it is produced or used. Acute (short-term) inhalation exposure of humans to maleic anhydride has been observed to cause irritation of the respiratory tract and eye irritation. Chronic (long-term) exposure […]

Bupivacaine, marketed under the brand name Marcaine among others, is a medication used to decrease feeling in a specific area. Bupivacaine is an amide-type, long-acting local anesthetic. Bupivicaine reversibly binds to specific sodium ion channels in the neuronal membrane, resulting in a decrease in the voltage-dependent membrane permeability to sodium ions and membrane stabilization; inhibition […]

Diatrizoate Meglumine is the meglumine salt form of diatrizoate, an organic, iodinated, radiopaque X-ray contrast medium used in diagnostic radiography. The iodine moiety of diatrizoate meglumine is not penetrable by X-rays, therefore blocks the X-ray film exposure by radiation. This makes it possible to distinguish on X-ray film, body parts that contain diatrizoate meglumine from […]

Acetylcysteine is a synthetic N-acetyl derivative of the endogenous amino acid L-cysteine, a precursor of the antioxidant enzyme glutathione. Acetylcysteine regenerates liver stores of glutathione. This agent also reduces disulfide bonds in mucoproteins, resulting in liquification of mucus. Some evidence suggests that acetylcysteine may exert an anti-apoptotic effect due to its antioxidant activity, possibly preventing […]

Aspirin or acetylsalicylic acid is perhaps the most commonly used analgesic and antipyretic medication worldwide, having been in clinical use for over 100 years. Aspirin can cause several forms of liver injury: in high doses, aspirin can cause moderate to marked serum aminotransferase elevations occasionally with jaundice or signs of liver dysfunction, and in lower […]

Alcuronium is an indole alkaloid of the curare family. A neuroblocker, it is often used in chloride form as an anesthesia adjuvant. It has a role as a muscle relaxant.

Allopurinol is a structural isomer of hypoxanthine. Allopurinol inhibits xanthine oxidase, an enzyme that converts oxypurines to uric acid. By blocking the production of uric acid, this agent decreases serum and urine concentrations of uric acid, thereby providing protection against uric acid-mediated end organ damage in conditions associated with excessive production of uric acid, i.e. […]

Amaranth is a dark red to dark purple powder. Almost no odor. Tastes salty. pH (1% solution in water) approximately 10.8. Used to dye wool and silk bright bluish-red from an acid bath.

A tetraiodofluorescein used as a red coloring in some foods (cherries, fish), as a disclosure of DENTAL PLAQUE, and as a stain of some cell types. It has structural similarity to THYROXINE.
