Acetylcysteine solution is for inhalation (mucolytic agent) or oral administration (acetaminophen antidote), available as a sterile, unpreserved solutions (not for injection). The solutions contain 20% (Acetylcysteine Solution 20%) or 10% (Acetylcysteine Solution 10%) acetylcysteine, with disodium edetate in water for injection. Sodium hydroxide and/or hydrochloric acid is added to adjust to pH (range 6.0 - 7.5). Acetylcysteine is the N-acetyl derivative of the naturally-occurring amino acid, L-cysteine. The compound is a white crystalline powder with the molecular formula C 5 H 9 NO 3 S, a molecular weight of 163.2, and chemical name of N-acetyl-L-cysteine. Acetylcysteine has the following structural formula: This product contains the following inactive ingredients: edetate disodium, sodium hydroxide and water for injection. Chemical Structure

Entecavir is a guanosine nucleoside analogue with selective activity against HBV. The chemical name for entecavir is 2-amino-1,9-dihydro-9-[( 1S,3R,4S )-4-hydroxy-3- (hydroxymethyl)-2-methylenecyclopentyl]-6 H -purin-6-one, monohydrate. Its molecular formula is C 12 H 15 N 5 O 3 ∙H 2 O, which corresponds to a molecular weight of 295.3. Entecavir has the following structural formula: Entecavir is a white to off-white powder. It is slightly soluble in water (2.4 mg/mL), and the pH of the saturated solution in water is 7.9 at 25 °C ± 0.5 °C. Entecavir film-coated tablets are available for oral administration in strengths of 0.5 mg and 1 mg of entecavir. Entecavir 0.5 mg and 1 mg film-coated tablets contain the following inactive ingredients: lactose monohydrate, microcrystalline cellulose, crospovidone, povidone, and magnesium stearate. The tablet coating contains titanium dioxide, hypromellose, polyethylene glycol 400, polysorbate 80 (0.5 mg tablet only), and iron oxide red (1 mg tablet only). FDA approved dissolution test specifications differ from USP. Chemical Structure

The barbiturates are nonselective central nervous system (CNS) depressants which are primarily used as sedative hypnotics and also anticonvulsants in subhypnotic doses. The barbiturates and their sodium salts are subject to control under the Federal Controlled Substances Act (CIV). Barbiturates are substituted pyrimidine derivatives in which the basic structure common to these drugs is barbituric acid, a substance which has no central nervous system activity. CNS activity is obtained by substituting alkyl, alkenyl or aryl groups on the pyrimidine ring. Phenobarbital Sodium Injection, USP is a sterile solution for intramuscular or slow intravenous administration as a long-acting barbiturate. Each mL contains phenobarbital sodium either 65 mg or 130 mg, alcohol 0.1 mL, propylene glycol 0.678 mL and benzyl alcohol 0.015 mL in Water for Injection; hydrochloric acid added, if needed, for pH adjustment. The pH range is 9.2-10.2. Chemically, phenobarbital sodium is 2,4,6(1 H ,3 H ,5 H )-Pyrimidinetrione,5-ethyl-5-phenyl-, monosodium salt and has the following structural formula: C12 H 11 N 2 NaO 3 MW 254.22 The sodium salt of phenobarbital occurs as a white, slightly bitter powder, crystalline granules or flaky crystals; it is soluble in alcohol and practically insoluble in ether or chloroform.
