Lopinavir and Ritonavir Tablets, USP is a co-formulation of lopinavir USP and ritonavir USP. Lopinavir USP is an inhibitor of the HIV-1 protease. As co-formulated in lopinavir and ritonavir, ritonavir USP inhibits the CYP3A-mediated metabolism of lopinavir USP, thereby providing increased plasma levels of lopinavir USP. Lopinavir USP is chemically designated as [1 S -[1 R *, ( R *),3 R *,4 R *]]- N -[4-[[(2,6-dimethylphenoxy) acetyl]amino]-3-hydroxy-5-phenyl-1-(phenylmethyl)pentyl]tetrahydro-alpha-(1-methylethyl)-2-oxo-1(2 H )-pyrimidineacetamide. Its molecular formula is C 37 H 48 N 4 O 5 , and its molecular weight is 628.80. Lopinavir USP is a white to off-white powder. It is practically insoluble in water, freely soluble in methanol, ethanol and in isopropyl alcohol. Lopinavir USP has the following structural formula: Ritonavir USP is chemically designated as 2,4,7,12-tetraazatridecan-13-oic acid, 10-hydroxy-2-methyl-5-(1-methylethyl)-1-[2-(1-methylethyl)-4-thiazolyl]-3,6-dioxo-8,11-bis(phenylmethyl)-5-thiazolylmethyl ester, [5S-(5R*,8R*,10R*,11R*)]. Its molecular formula is C 37 H 48 N 6 O 5 S 2 , and its molecular weight is 720.94. Ritonavir USP is a white to off-white powder. It is freely soluble in methanol, methylene chloride, sparingly soluble in acetonitrile and practically insoluble in water. Ritonavir USP has the following structural formula: Lopinavir and ritonavir film coated tablets USP are available for oral administration in two strengths: • Yellow tablets containing 200 mg of lopinavir USP and 50 mg of ritonavir USP • Yellow tablets containing 100 mg of lopinavir USP and 25 mg of ritonavir USP The yellow, 200 mg lopinavir/50 mg ritonavir, tablets contain the following inactive ingredients: colloidal silicon dioxide, copovidone, sodium stearyl fumarate, sorbitan monolaurate and opadry yellow which contains colloidal anhydrous silica, hypromellose, hydroxypropyl cellulose, iron oxide yellow, polyethylene glycol, polysorbate 80, talc and titanium dioxide. The yellow, 100 mg lopinavir/25 mg ritonavir, tablets contain the following inactive ingredients: colloidal silicon dioxide, copovidone, sodium stearyl fumarate, sorbitan monolaurate and opadry yellow which contains colloidal anhydrous silica, hypromellose, hydroxypropyl cellulose, iron oxide yellow, polyethylene glycol, polysorbate 80, talc and titanium dioxide. lopiandritotabstructure1 lopiandritotabstructure2
