Theophylline is structurally classified as a methylxanthine. It occurs as a white, odorless, crystalline powder with a bitter taste. Anhydrous theophylline has the chemical name 1H-Purine-2,6-dione,3,7-dihydro-1,3-dimethyl-, and is represented by the following structural formula:

OSMITROL Injection (Mannitol Injection, USP) is a sterile, nonpyrogenic solution of Mannitol, USP in a single dose container for intravenous administration. It contains no antimicrobial agents. Mannitol** is a six carbon sugar alcohol prepared commercially by the reduction of dextrose. Although virtually inert metabolically in humans, it occurs naturally in fruits and vegetables. Mannitol is an obligatory osmotic diuretic. The pH is adjusted with sodium hydroxide or hydrochloric acid. Composition, osmolarity, and pH are shown in Table 1.

Plasma-Lyte® 56 and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) is a sterile, nonpyrogenic solution for fluid and electrolyte replenishment and caloric supply in a single dose container for intravenous administration. Each 100 mL contains 5 g Dextrose Hydrous, USP*, 234 mg Sodium Chloride, USP (NaCl); 128 mg Potassium Acetate, USP (C2H3KO2); and 32 mg Magnesium Acetate, Tetrahydrate (C4H6MgO4•4H2O). It contains no antimicrobial agents. pH 5.0 (4.0 to 6.5). The pH is adjusted with hydrochloric acid.
