Voltaren® Gel (diclofenac sodium topical gel) is a nonsteroidal anti-inflammatory drug (NSAID) for topical use only. It contains the active ingredient, diclofenac sodium, in an opaque, white gel base. Diclofenac sodium is a white to slightly yellow crystalline powder. Diclofenac sodium is a benzene–acetic acid derivative. The chemical name is 2-[ (2,6-dichlorophenyl)amino]benzeneacetic acid, monosodium salt. The molecular weight is 318.14. Its molecular formula is C14H10Cl2NNaO2. It has the following structural formula:

Voluven® (6% hydroxyethyl starch 130/0.4 in 0.9% sodium chloride injection) is a clear to slightly opalescent, colorless to slightly yellow, sterile, non-pyrogenic, isotonic solution for intravenous administration using sterile equipment.

Voltaren Ophthalmic (diclofenac sodium ophthalmic solution) 0.1% solution is a sterile, topical, nonsteroidal, anti-inflammatory product for ophthalmic use. Diclofenac sodium is designated chemically as 2-[(2,6-dichlorophenyl)amino] benzeneacetic acid, monosodium salt, with an empirical formula of C14H10Cl2NO2Na. The structural formula of diclofenac sodium is:

Hydroxyzine pamoate is designated chemically as 1-(p-chlorobenzhydryl) 4- [2-(2-hydroxyethoxy) ethyl] diethylenediamine salt of 1,1 -methylene bis (2 hydroxy- 3-naphthalene carboxylic acid).

VIRAZOLE is a brand name for ribavirin, a synthetic nucleoside with antiviral activity. VIRAZOLE (ribavirin) for inhalation solution is a sterile, lyophilized powder to be reconstituted for aerosol administration. Each 100 mL glass vial contains 6 grams of ribavirin, and when reconstituted to the recommended volume of 300 mL with sterile water for injection or sterile water for inhalation (no preservatives added), will contain 20 mg of ribavirin per mL, pH approximately 5.5. Aerosolization is to be carried out in a Small Particle Aerosol Generator (SPAG-2) nebulizer only.

The active component of VENTOLIN HFA is albuterol sulfate, USP, the racemic form of albuterol and a relatively selective beta2-adrenergic bronchodilator. Albuterol sulfate has the chemical name ?1-[(tert-butylamino)methyl]-4-hydroxy-m-xylene-?, ?' -diol sulfate (2:1)(salt) and the following chemical structure:

Vitravene† (fomivirsen sodium intravitreal injectable) is a sterile, aqueous, preservative-free, bicarbonate-buffered solution for intravitreal injection. Fomivirsen sodium is represented by the following structual formula:

Phytonadione is a vitamin, which is a clear, yellow to amber, viscous, odorless or nearly odorless liquid. It is insoluble in water, soluble in chloroform and slightly soluble in ethanol. It has a molecular weight of 450.70.

VAGIFEM® (estradiol vaginal tablets) are small, white, film-coated tablets containing 25.8?µg of estradiol hemihydrate equivalent to 25?µg of estradiol.

CHANTIX tablets contain varenicline (as the tartrate salt), which is a partial agonist selective for ?4?2 nicotinic acetylcholine receptor subtypes.
