Buspirone hydrochloride, USP is a white crystalline powder. It is very soluble in water; freely soluble in methanol and in methylene chloride; sparingly soluble in ethanol and in acetonitrile; very slightly soluble in ethyl acetate and practically insoluble in hexanes. Its molecular weight is 422. Chemically, buspirone hydrochloride is 8-[4-[4-(2-pyrimidinyl)-1-piperazinyl]butyl]-8-azaspiro[4.5]decane-7,9-dione monohydrochloride. The molecular formula C21H31N5O2•HCl is represented by the following structural formula: Each buspirone hydrochloride tablet intended for oral administration contains 5 mg or 7.5 mg or 10 mg or 15 mg or 30 mg buspirone hydrochloride (equivalent to 4.6 mg, 6.85 mg, 9.1 mg, 13.7 mg, and 27.4 mg of buspirone free base, respectively). In addition, each tablet contains the following inactive ingredients: colloidal silicon dioxide, lactose monohydrate, magnesium stearate, microcrystalline cellulose and sodium starch glycolate. The 5 mg and 10 mg tablets are scored so they can be bisected. Thus, the 5 mg tablet can also provide 2.5 mg dose, and the 10 mg tablet can provide a 5 mg dose. The 15 mg and 30 mg tablets are scored so they can be either bisected or trisected. Thus, a single 15 mg tablet can provide the following doses: 15 mg (entire tablet), 10 mg (two thirds of a tablet), 7.5 mg (one half of a tablet), or 5 mg (one third of a tablet). A single 30 mg tablet can provide the following doses: 30 mg (entire tablet), 20 mg (two thirds of a tablet), 15 mg (one half of a tablet), or 10 mg (one third of a tablet). Structural formula
