Docetaxel is an antineoplastic agent belonging to the taxoid family. It is prepared by semisynthesis beginning with a precursor extracted from the renewable needle biomass of yew plants. The chemical name for docetaxel (anhydrous) is (2R,3S)-N-carboxy-3-phenylisoserine,N-tert-butyl ester, 13-ester with 5?-20epoxy-1,2?,4,7?,10?,13?-hexahydroxytax-11-en-9-one 4-acetate 2-benzoate. Docetaxel (anhydrous) has the following structural formula:

Duagen (dutasteride) is a synthetic 4-azasteroid compound that is a selective inhibitor of both the type 1 and type 2 isoforms of steroid 5?-reductase (5AR), an intracellular enzyme that converts testosterone to 5?-dihydrotestosterone (DHT).

Each capsule of DYAZIDE (hydrochlorothiazide and triamterene) for oral use, with opaque red cap and opaque white body, contains hydrochlorothiazide 25 mg and triamterene 37.5 mg, and is imprinted with the product name DYAZIDE (hydrochlorothiazide and triamterene) and SB. Hydrochlorothiazide is a diuretic/antihypertensive agent and triamterene is an antikaliuretic agent.

Cardizem (diltiazem hydrochloride) is a calcium ion cellular influx inhibitor (slow channel blocker or calcium antagonist). Chemically, diltiazem hydrochloride is 1,5-Benzothiazepin4(5H)-one, 3-(acetyloxy)-5-[2-(dimethylamino)ethyl]-2, 3-dihydro-2-(4-methoxyphenyl)-, monohydrochloride,(+)-cis-. The chemical structure is:

Deconsal DM (phenylephrine, pyrilamine maleate, and dextromethorphan hbr) Tannate Chewable Tablets are an antihistamine/nasal decongestant/antitussive combination for oral administration as a chewable tablet. Each Deconsal DM (phenylephrine, pyrilamine maleate, and dextromethorphan hbr) Tannate Chewable Tablet in a grape-flavored, dye-free, mottled brown-colored, scored tablet for oral administration contains:

The ATRIDOX (doxycycline hyclate) product is a subgingival controlled-release product composed of a two syringe mixing system. Syringe A contains 450 mg of the ATRIGEL Delivery System, which is a bioabsorbable, flowable polymeric formulation composed of 36.7% poly(DLlactide) (PLA) dissolved in 63.3% N-methyl-2-pyrrolidone (NMP). Syringe B contains 50 mg of doxycycline hyclate which is equivalent to 42.5 mg doxycycline. The constituted product is a pale yellow to yellow viscous liquid with a concentration of 10% of doxycycline hyclate. Upon contact with the crevicular fluid, the liquid product solidifies and then allows for controlled release of drug for a period of 7 days. Doxycycline is a broad-spectrum antibiotic synthetically derived from oxytetracycline.
