    摘要: The present invention relates to a process for preparation of a delta-9-tetrahydrocannabinol compound or derivative thereof involving treating a first intermediate compound with an organoaluminum-based Lewis acid catalyst, under conditions effective to produce the delta-9-tetrahydrocannabinol compound or derivative thereof. Another aspect of the present invention relates to a process for preparation of a cannabidiol or cannabidiolate compound involving reacting a first starting compound with a second starting compound in the presence of a metal triflate catalyst, under conditions effective to form the cannabidiol or cannabidiolate compound. The present invention also relates to a compound of the formula: where R8, R9, and R10 are the same or different and independently selected from the group consisting of H, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, or halo, with R1, R2, and R3 defined herein.

    摘要: The present invention relates to a dry blend, used for forming azithromycin tablets by direct compression, comprising non-dihydrate azithromycin and at least one pharmaceutically acceptable excipient. This invention also relates to an azithromycin tablet comprising non-dihydrate azithromycin and at least one pharmaceutically acceptable excipient. Preferably, the azithromycin tablet is formed by directly compressing the dry blend, of the present invention, to form said azithromycin tablet. Preferably, the azithromycin tablet, of the present invention, contains a dosage of 250 mgA, 500 mgA or 600 mgA of azithromycin. This invention further relates to an azithromycin tablet which is produced by forming a dry blend of a non-granulated azithromycin form A and at least one pharmaceutically acceptable excipient. The azithromycin tablet is then formed by directly compressing the dry blend.

    摘要: This invention relates to a powder for oral suspension, and an oral suspension made therefrom, which comprises non-dihydrate azithromycin and an azithromycin conversion stabilizing excipient, wherein said excipient reduces the conversion of the form of azithromycin, when placed in suspension, to another form of azithromycin. This invention further relates to a method for reducing the conversion of a form of non-dihydrate azithromycin, in an oral suspension, by adding a surface tension reducing excipient that reduces the surface tension of the aqueous vehicle. Furthermore, this invention relates to a method for reducing the conversion of a non-dihydrate azithromycin, in an unflavored oral suspension, by raising the viscosity of the oral suspension, and in a flavored oral suspension by lowering the viscosity of the oral suspension.
