Doryx MPC (doxycycline hyclate delayed-release tablets) for oral use, contain doxycycline hyclate, a tetracycline class drug synthetically derived from oxytetracycline, in a delayed-release formulation consisting of pellets with a modified polymer enteric coat that has increased acid resistance. The structural formula for doxycycline hyclate is: with a molecular formula of C 22 H 24 N 2 O 8 , HCl, ½ C 2 H 6 O, ½ H 2 O and a molecular weight of 512.9. The chemical name for doxycycline hyclate is [4S(4aR,5S,5aR,6R,12aS)]-4-(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro-3,5,10,12,12a-pentahydroxy-6-methyl-1,11-deoxonaphthacene-2-carboxamide monohydrochloride, compound with ethyl alcohol (2:1), monohydrate. Doxycycline hyclate is a yellow crystalline powder soluble in water and in solutions of alkali hydroxides and carbonates. Doxycycline has a high degree of lipid solubility and a low affinity for calcium binding. It is highly stable in normal human serum. Doxycycline will not degrade into an epianhydro form. Each tablet contains doxycycline 60 mg (equivalent to doxycycline hyclate 69.4 mg) or doxycycline 120 mg (equivalent to doxycycline hyclate 138.8 mg). Inactive ingredients in the tablet formulation are: lactose monohydrate; microcrystalline cellulose; sodium lauryl sulfate; sodium chloride; talc; anhydrous lactose; corn starch; crospovidone; magnesium stearate; cellulosic polymer coating. Each DORYX MPC 60 mg Tablet contains 3.6 mg (0.157 mEq) of sodium. Each DORYX MPC 120 mg Tablet contains 7.2 mg (0.313 mEq) of sodium. Chemical Structure
