Abstract
The present invention provides a composition comprising a cefditoren, or a salt, derivative, prodrug, or other form thereof, for example, cefditoren pivoxil, useful in the treatment and prevention of infections and related conditions. The invention provides a composition which comprises nanoparticulate particles comprising the cefditoren, or a salt, derivative, prodrug, or other form thereof and at least one surface stabilizer. The nanoparticulate particles have an effective average particle size of less than about 2000 nm. The invention provides also a composition that delivers a cefditoren, or a salt, derivative, prodrug, or other form thereof, or nanoparticles comprising the same, in a pulsatile or continuous manner.
