MUSTARGEN (mechlorethamine hcl) , an antineoplastic nitrogen mustard also known as HN2 hydrochloride, is a nitrogen analog of sulfur mustard. It is a light yellow brown, crystalline, hygroscopic powder that is very soluble in water and also soluble in alcohol.

Each Asacol HD delayed-release tablet for oral administration contains 800 mg of mesalamine, an antiinflammatory drug. Asacol HD delayed-release tablets have an outer protective coat consisting of a combination of acrylic based resins, Eudragit S (methacrylic acid copolymer B, NF) and Eudragit L (methacrylic acid copolymer A, NF). The inner coat consists of an acrylic based resin, Eudragit S, which dissolves at pH 7 or greater, releasing mesalamine in the terminal ileum and beyond for topical anti-inflammatory action in the colon. Mesalamine (also referred to as 5-aminosalicylic acid or 5-ASA) has the chemical name 5-amino-2-hydroxybenzoic acid; its structural formula is:

Methylin® (methylphenidate HCl) is a mild central nervous system (CNS) stimulant, available as 2.5 mg, 5 mg and 10 mg chewable tablets for oral administration. Methylphenidate hydrochloride is methyl ? -phenyl-2-piperidineacetate hydrochloride, and its structural formula is

Myfortic® (mycophenolic acid) delayed-release tablets are an enteric formulation of mycophenolate sodium that delivers the active moiety mycophenolic acid (MPA). Myfortic (mycophenolic acid) is an immunosuppressive agent. As the sodium salt, MPA is chemically designated as (E)-6-(4hydroxy-6-methoxy-7-methyl-3-oxo-1,3-dihydroisobenzofuran-5-yl)-4-methylhex-4-enoic acid sodium salt.

Metronidazole Injection, USP RTU®, is a parenteral dosage form of the synthetic antibacterial agent 1-(??-hydroxyethyl)-2-methyl-5-nitroimidazole.

OVIDE Lotion contains 0.005 g of malathion per mL in a vehicle of isopropyl alcohol (78%), terpineol, dipentene, and pine needle oil. The chemical name of malathion is (±) - [(dimethoxyphosphinothioyl) - thio] butanedioic acid diethyl ester. Malathion has a molecular weight of 330.36, represented by C10H19O6PS2, and has the following chemical structure:

METAGLIP™ (glipizide and metformin HCl) Tablets contain 2 oral antihyperglycemic drugs used in the management of type 2 diabetes, glipizide and metformin hydrochloride.

Megace® ES (megestrol acetate) oral suspension contains megestrol acetate, a synthetic derivative of the naturally occurring steroid hormone, progesterone. Megestrol acetate is a white, crystalline solid chemically designated as 17-Hydroxy-6-methylpregna-4,6-diene-3,20-dione acetate. Solubility at 37° C in water is 2 µg per mL, solubility in plasma is 24 µg per mL. Its molecular weight is 384.52.

ProQuad (measles mumps rubella varicella vaccine live) * is a combined attenuated live virus vaccine containing measles, mumps, rubella, and varicella viruses. ProQuad (measles mumps rubella varicella vaccine live) is a sterile lyophilized preparation of (1) the components of M-M-R*ll (Measles, Mumps and Rubella Virus Vaccine Live): Measles Virus Vaccine Live, a more attenuated line of measles virus, derived from Enders' attenuated Edmonston strain and propagated in chick embryo cell culture; Mumps Virus Vaccine Live, the Jeryl Lynn™ (B level) strain of mumps vims propagated in chick embryo cell culture; Rubella Virus Vaccine Live, the Wistar RA 27/3 strain of live attenuated rubella virus propagated in WI-38 human diploid lung fibroblasts; and (2) Varicella Virus Vaccine Live (Oka/Merck), the Oka/Merck strain of varicella-zoster virus propagated in MRC-5 cells. The cells, virus pools, bovine serum, and human albumin used in manufacturing are all tested to provide assurance that the final product is free of potential adventitious agents.

Mycamine is a sterile, lyophilized product for intravenous (IV) infusion that contains micafungin sodium. Micafungin sodium is a semisynthetic lipopeptide (echinocandin) synthesized by a chemical modification of a fermentation product of Coleophoma empetri F-l 1899. Micafungin inhibits the synthesis of 1, 3-?-D-glucan, an integral component of the fungal cell wall.
