EMSAM (selegiline transdermal system) is a transdermally administered antidepressant. When applied to intact skin, EMSAM (selegiline transdermal system) is designed to continuously deliver selegiline over a 24-hour period. Selegiline base is a colorless to yellow liquid, chemically described as (-)-(N)-Methyl- N-[(1 R)-1-methyl-2- phenylethyl]prop-2-yn-1-amine. It has an empirical formula of C13H17N and a molecular weight of 187.30. The structural formula is:

ProSom (estazolam), a triazolobenzodiazepine derivative, is an oral hypnotic agent. Estazolam occurs as a fine, white, odorless powder that is soluble in alcohol and practically insoluble in water. The chemical name for estazolam is 8-chloro-6-phenyl-4Hs-triazolo[4,3-?] [1,4]benzodiazepine. The empirical formula is C16H11ClN4. The structural formula is represented as follows:

Each tablet of Equagesic (meprobamate and aspirin) contains 200 mg meprobamate and 325 mg aspirin. The inactive ingredients present are cellulose, D&C Yellow 10, FD&C Red 3, FD&C Yellow 6, hydrogenated vegetable oil, magnesium stearate, polacrilin potassium, and starch.

ELAPRASE is a formulation of idursulfase, a purified form of human iduronate-2-sulfatase, a lysosomal enzyme. Idursulfase is produced by recombinant DNA technology in a human cell line. Idursulfase is an enzyme that hydrolyzes the 2-sulfate esters of terminal iduronate sulfate residues from the glycosaminoglycans dermatan sulfate and heparan sulfate in the lysosomes of various cell types.

VePesid (etoposide) (also commonly known as VP-16) is a semisynthetic derivative of podophyllotoxin used in the treatment of certain neoplastic diseases. It is 4'-demethylepipodophyllotoxin 9-[4,6-O-(R)-ethylidene-?-D-glucopyranoside]. It is very soluble in methanol and chloroform, slightly soluble in ethanol, and sparingly soluble in water and ether. It is made more miscible with water by means of organic solvents. It has a molecular weight of 588.56 and a molecular formula of C29H32O13.

Each tablet for oral administration contains 1 mg ergotamine tartrate, USP, and 100 mg caffeine, USP.

Soliris, a complement inhibitor, is a formulation of eculizumab which is a recombinant humanized monoclonal IgG2/4? antibody produced by murine myeloma cell culture and purified by standard bioprocess technology. Eculizumab contains human constant regions from human IgG2 sequences and human IgG4 sequences and murine complementarity-determining regions grafted onto the human framework light- and heavy-chain variable regions. Eculizumab is composed of two 448 amino acid heavy chains and two 214 amino acid light chains and has a molecular weight of approximately 148 kDa.

Extina (ketoconazole foam, 2%) Foam contains 2% ketoconazole USP, an antifungal agent, in a thermolabile hydroethanolic foam for topical application. The chemical name for ketoconazole is piperazine, 1-acetyl-4-[4-[[2-(2,4-dichlorophenyl) -2-(1H-imidazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]-, cis- with the molecular formula C26H28Cl2N4O4 and a molecular weight of 531.43. The following is the chemical structure:

Ethiodol, brand of ethiodized oil, is a sterile injectable radio-opaque diagnostic agent for use in hysterosalpingography and lymphography. It contains 37% iodine (475 mg/mL) organically combined with ethyl esters of the fatty acids (primarily as ethyl monoiodostearate and ethyl diiodostearate) of poppyseed oil. Stabilized with poppyseed oil, 1%. The precise structure of Ethiodol (ethiodized oil) is unknown at this time. Ethiodol (ethiodized oil) is a straw to amber colored, oily fluid, which because of simplified molecular structure, possesses a greatly reduced viscosity (1.280 specific gravity at 15 C yields viscosity of 0.5 - 1.0 poise). This high fluidity provides a new flexibility for radiographic exploration.

Entex LA (guaifenesin and phenylephrine) is an orange, scored, long-acting tablet for oral administration and contains
