    摘要: A pharmaceutical composition includes erythromycin A or a derivative thereof and alginic acid. The alginic acid provides taste masking of the erythromycin A or derivative. The erythromycin A derivative may be clarithromycin and the alginic acid may be one or both of alginic acid and its salt. The salt may be one or more of sodium alginate and calcium alginate. The pharmaceutical composition may further include one or more of a binder, a disintegrant, a flavoring agent, and a coating. The pharmaceutical composition also may include one or more active ingredients, including omeprazole, metronidazole, amoxicillin, rifampicin, lansoprazole, ciprofloxacin, ethambutol, and ritonavir. The erythromycin A or a derivative thereof and the one or more active ingredients may be combined in a single pharmaceutical composition.

    摘要: A pharmaceutical composition in the form of a tablet or a capsule for the controlled release of diltiazem, comprises about 30 to about 97% by weight of a hydrophilic polymer, about 0.5 to about 30% by weight of an enteric (pH-dependent) polymer, and about 2.5 to about 60% by weight of diltiazem or a pharmaceutically acceptable salt or ester thereof. The ratio of hydrophilic polymer to enteric polymer is in the range of about 1:1 to about 15:1. Such a pharmaceutical composition releases diltiazem at a rate that allows effective plasma levels of diltiazem to be maintained over a period of twenty-four hours after administration to human adult subjects.
