摘要:
Pharmaceutical compositions of crystalline azithromycin-containing multiparticulates having low concentrations of azithromycin ester degradants and exhibiting controlled release of the drug are achieved by inclusion of dissolution enhancers having low concentrations of acid and ester substituents.
摘要:
A multiparticulate for controlled release of a drug comprises crystalline drug, a glyceride having at least one alkylate substituent of at least 16 carbon atoms, and a poloxamer, wherein at least 70 wt % of the drug in the multiparticulate is crystalline.
摘要:
The present invention is related to an oral dosage form comprising an effective amount of an alkalizing agent and an azithromycin multiparticulate wherein said multiparticulate comprises azithromycin, a glyceride which comprises glyceryl monobehenate, glyceryl dibehenate, glyceryl tribehenate, or a mixture thereof and a poloxamer. Typically, the oral dosage form includes any suitable oral dosing means such as a powder for oral suspension, a unit dose packet or sachet, a tablet or a capsule.

摘要:
An oral dosage form comprising azithromycin and an effective amount of an alkalizing agent. Preferably, said oral dosage form comprises an effective amount of an alkalizing agent and an azithromycin multiparticulate wherein said multiparticulate comprises azithromycin, a mixture of glyceryl monobehenate, glyceryl dibehenate and glyceryl tribehenate, and a poloxamer. Typically, the oral dosage form includes any suitable oral dosing means such as a powder for oral suspension, a unit dose packet or sachet, a tablet or a capsule. Additionally disclosed is an oral suspension comprising azithromycin, an effective amount of an alkalizing agent and a vehicle. Preferably, the azithromycin is in multiparticulate form wherein said multiparticulate comprises azithromycin, a mixture of glyceryl monobehenate, glyceryl dibehenate and glyceryl tribehenate, and a poloxamer. Also disclosed is a method for reducing gastrointestinal side effects, associated with administering azithromycin to a mammal, comprising contiguously administering azithromycin and an effective amount of alkalizing agent to said mammal wherein the frequency of gastrointestinal side effects is lower than that experienced by administering an equal dose of azithromycin without said alkalizing agent. Further disclosed is a method of treating a bacterial or protozoal infection in a mammal in need thereof comprising contiguously administering to said mammal a single dose of an oral dosage form wherein said oral dosage form comprises azithromycin and an effective amount of an alkalizing agent. Additionally disclosed are azithromycin multiparticulates comprising azithromycin, a surfactant; and a pharmaceutically acceptable carrier.
摘要:
A process for forming multiparticulates of azithromycin and a controlled release dosage form comprising multiparticulates of azithromycin and a pharmaceutically acceptable excipient are disclosed. The dosage form decreases the incidence and/or severity of GI side effects relative to currently available immediate release azithromycin dosage forms that deliver an equivalent dose. The dosage forms operate by effecting azithromycin release at a rate sufficiently slow to ameliorate side effects, yet sufficiently fast to achieve good bioavailability.
