Mupirocin Antibiotic Composition

Abstract

An antibiotic inhalation or irrigation composition for the treatment of bacterial infections especially in the respiratory tract, is provided. The antibiotic inhalation or irrigation composition may include a mixture of mupirocin as active pharmaceutical ingredient (API), and a micronized poloxamer composition as excipient. Micronized poloxamer composition may be produced by mixing poloxamer 188 and poloxamer 407 in an apparatus where a low-frequency acoustic field is applied to facilitate mixing. Antibiotic inhalation or irrigation composition may be obtained in powder or solution form. In other embodiments, antibiotic inhalation or irrigation composition may be employed to produce a topical formulation for the treatment of traumatic skin lesions. In some embodiments, other suitable poloxamers or sugar alcohols may be employed as excipients. Due to the synergistic effect of micronized poloxamer composition, antibiotic inhalation or irrigation composition may provide improved solubility and bioavailability of mupirocin, thus decreasing side effects and time of treatment.
