Azithromycin multiparticulate dosage forms by liquid-based processes |
| abstract |
Liquid-based processes are disclosed for forming azithromycin multiparticulates having minimal amounts of azithromycin esters. A liquid-based process for the formation of multiparticulates comprising the steps: (a) forming a mixture comprising azithromycin, a pharmaceutically acceptable carrier, and at least one liquid having a boiling point of less than about 150 C; (b) forming particles from said mixture of step (a) by a method selected from (i) atomization of said mixture, and (ii) coating seed cores with said mixture; and (c) removing a substantial portion of said liquid from said particles of step (b) to form said multiparticulates wherein the following expression is satisfied: [A] <= 0.04/(1-x), where [A] is the concentration of acid/ester substitution on the carrier in meq/g azithromycin, and x is the weight fraction of the azithromycin in said multiparticulates that is crystalline. |
