Locoid Lipocream contains hydrocortisone butyrate, a non-fluorinated hydrocortisone ester [Pregn-4-ene-3, 20-dione, 11, 21-dihydroxy-17- [(1-oxobutyl) oxy (11?)-] for topical dermatologic use.

LIPITOR (atorvastatin calcium) is a synthetic lipid-lowering agent. Atorvastatin is an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. This enzyme catalyzes the conversion of HMG-CoA to mevalonate, an early and rate-limiting step in cholesterol biosynthesis.

Levoleucovorin is the levo isomeric form of racemic d,l-leucovorin, present as the calcium salt. Levoleucovorin is the pharmacologically active isomer of leucovorin [(6-S)-leucovorin].

MEVACOR (Lovastatin) is a cholesterol lowering agent isolated from a strain of Aspergillus terreus. After oral ingestion, lovastatin, which is an inactive lactone, is hydrolyzed to the corresponding ?hydroxyacid form. This is a principal metabolite and an inhibitor of 3-hydroxy-3-methylglutarylcoenzyme A (HMG-CoA) reductase. This enzyme catalyzes the conversion of HMG-CoA to mevalonate, which is an early and rate limiting step in the biosynthesis of cholesterol.

Seasonale® (levonorgestrel/ethinyl estradiol tablets) is an extended-cycle oral contraceptive consisting of 84 pink active tablets each containing 0.15 mg of levonorgestrel, a synthetic progestogen and 0.03 mg of ethinyl estradiol, and 7 white inert tablets (without hormones).

Dianeal Low Calcium peritoneal dialysis solutions are sterile, nonpyrogenic solutions in Ambu-Flex III containers with flanged port for intraperitoneal administration only. They contain no bacteriostatic or antimicrobial agents or added buffers.

Lodine® (etodolac) is a member of the pyranocarboxylic acid group of nonsteroidal anti-inflammatory drugs (NSAIDs). Each tablet and capsule contains etodolac for oral administration. Etodolac is a racemic mixture of [+]S and [-]R-enantiomers. Etodolac is a white crystalline compound, insoluble in water but soluble in alcohols, chloroform, dimethyl sulfoxide, and aqueous polyethylene glycol.

LIMBITROL (chlordiazepoxide amitriptyline ds tablets) combines for oral administration, chlordiazepoxide, an agent for the relief of anxiety and tension, and amitriptyline, an antidepressant. It is available in DS (double strength) white, film-coated tablets, each containing 10 mg chlordiazepoxide and 25 mg amitriptyline (as the hydrochloride salt); and in blue, film-coated tablets, each containing 5 mg chlordiazepoxide and 12.5 mg amitriptyline (as the hydrochloride salt). Each tablet also contains corn starch, hydroxypropyl cellulose, hyproxypropyl methylcellulose, lactose, magnesium stearate, polyethylene glycol, povidone and propylene glycol; LIMBITROL (chlordiazepoxide amitriptyline ds tablets) tablets contain the following colorant system-FD&C Blue No. 1, aluminum lake and titanium dioxide. LIMBITROL (chlordiazepoxide amitriptyline ds tablets) DS tablets contain titanium dioxide.

Xopenex (levalbuterol HCI) Inhalation Solution is a sterile, clear, colorless, preservative-free solution of the hydrochloride salt of levalbuterol, the (R)-enantiomer of the drug substance racemic albuterol. Levalbuterol HCl is a relatively selective beta2-adrenergic receptor agonist (see CLINICAL PHARMACOLOGY). The chemical name for levalbuterol HCl is (R)-?1-[[(1,1-dimethylethyl)amino]methyl]-4-hydroxy-1,3-benzenedimethanol hydrochloride, and its established chemical structure is as follows:

Lindane Shampoo, USP 1%, is an ectoparasiticide and ovicide effective against Pediculosis humanis capitis (head lice), Pthirus pubis(crab lice), and their ova. In addition to the active ingredient, lindane, it contains triethanolamine lauryl sulfate, polysorbate 60, hydrochloric acid, acetone and purified water to form a shampoo base. The pH may be adjusted with 10% hydrochloric acid solution and/or 10% sodium hydroxide solution. Lindane is the gamma isomer of 1,2,3,4,5,6 hexachlorocyclohexane having the following structural formula:
