OCUCOAT (hydroxypropylmethylcellulose) is a sterile, isotonic, nonpyrogenic viscoelastic solution of highly purified, noninflammatory, 2% hydroxypropylmethylcellulose with a high molecular weight greater than 80,000 daltons. OCUCOAT (hydroxypropylmethylcellulose) is supplied in 1 mL syringes. Each mL provides 20 mg/mL of hydroxypropylmethylcellulose dissolved in a physiological balanced salt solution containing 0.49% sodium chloride, 0.075% potassium chloride, 0.048% calcium chloride, 0.03% magnesium chloride, 0.39% sodium acetate, 0.17% sodium citrate and water for injection. The osmolarity of OCUCOAT (hydroxypropylmethylcellulose) is 285 32 mOsM, the viscosity is 4000 1500 cst, and the pH is 7.20.4.

HORIZANT (gabapentin enacarbil) is a prodrug of gabapentin. Gabapentin enacarbil is described as (1-{[({(1RS)-1-[(2-Methylpropanoyl)oxy]ethoxy}carbonyl)amino]methyl} cyclohexyl) acetic acid. It has a molecular formula of C16H27NO6 and a molecular weight of 329.39. It is a recemate and has the following structural formula.

Heparin is a heterogeneous group of straight-chain anionic mucopolysaccharides, called glycosaminoglycans, having anticoagulant properties. Although others may be present, the main sugars occurring in heparin are: (1) _-L-iduronic acid 2-sulfate, (2) 2-deoxy-2- sulfamino-_-D-glucose 6-sulfate, (3) _-D-glucuronic acid, (4) 2 acetamido-2-deoxy-_-Dglucose and (5) _-L-iduronic acid. These sugars are present in decreasing amounts, usually in the order (2) > (1) > (4) > (3) > (5), and are joined by glycosidic linkages, forming polymers of varying sizes. Heparin is strongly acidic because of its content of covalently linked sulfate and carboxylic acid groups. In heparin sodium (heparin sodium injection preservative free) , the acidic protons of the sulfate units are partially replaced by sodium ions.

Humulin is synthesized in a special non-disease-producing laboratory strain of Escherichia coli bacteria that has been genetically altered to produce human insulin. Humulin 50/50 is a mixture of 50% Human Insulin Isophane Suspension and 50% Human Insulin Injection (rDNA origin). It is an intermediate-acting insulin combined with the more rapid onset of action of Regular human insulin. The duration of activity may last up to 24 hours following injection. The time course of action of any insulin may vary considerably in different individuals or at different times in the same individual. As with all insulin preparations, the duration of action of Humulin 50/50 is dependent on dose, site of injection, blood supply, temperature, and physical activity. Humulin 50/50 is a sterile suspension and is for subcutaneous injection only. It should not be used intravenously or intramuscularly. The concentration of Humulin 50/50 is 100 units/mL (U-100).

ZYDONE (hydrocodone bitartrate and acetaminophen tablets), for oral administration, contain hydrocodone bitartrate and acetaminophen in the following strengths:

Each HalfLytely and Bisacodyl Tablets (sodium chloride-sodium bicarbonate and potassium chloride) Bowel Prep Kit [Polyethylene glycol (PEG) 3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution and bisacodyl delayed release tablets] consists of one 2 liter bottle of HalfLytely (PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution) powder for reconstitution and two 5 mg bisacodyl, delayed release tablets.

pHisoHex, brand of hexachlorophene detergent cleanser, is an antibacterial sudsing emulsion for topical administration. pHisoHex contains a colloidal dispersion of hexachlorophene 3% (w/w) in a stable emulsion consisting of entsufon sodium, petrolatum, lanolin cholesterols, methylcellulose, polyethylene glycol, polyethylene glycol monostearate, lauryl myristyl diethanolamide, sodium benzoate, and water. pH is adjusted with hydrochloric acid. Entsufon sodium is a synthetic detergent.

The topical corticosteroids constitute a class of primarily synthetic steroids used as antiinflammatory and antipruritic agents. The steroids in this class include halcinonide. Halcinonide is designated chemically as 21-Chloro-9-fluoro-11?,16?, 17-trihydroxy-pregn-4-ene-3,20-dione cyclic 16,17-acetal with acetone. Graphic formula:

Levsin tablets (hyoscyamine sulfate tablets USP) contain 0.125 mg hyoscyamine sulfate formulated for oral administration.

Heparin is a heterogeneous group of straight-chain anionic mucopolysaccharides, called glycosaminoglycans having anticoagulant properties. Although others may be present, the main sugars occurring in heparin are: (1)? -L-iduronic acid 2-sulfate, (2) 2-deoxy-2-sulfamino-? -D-glucose 6-sulfate, (3) ?-D-glu-curonic acid, (4) 2-acetamido-2-deoxy-? -D-glucose and (5)? -L-iduronic acid. These sugars are present in decreasing amounts, usually in the order (2) > (1) > (4) > (3) > (5), and are joined by glycosidic linkages, forming polymers of varying sizes. Heparin is strongly acidic because of its content of covalently linked sulfate and carboxylic acid groups. In heparin sodium, the acidic protons of the sulfate units are partially replaced by sodium ions.
