Brief summary
Cefixime is an orally active third generation cephalosporin indicated for the treatment of acute exacerbations of chronic bronchitis, acute otitis media, uncomplicated acute cystitis and uncomplicated pyelonephritis. Cefixime acts by inhibiting the action of proteins involved in the synthesis of bacterial cell walls, which leads to bacterial cell lysis and cell death. Due to lack of bioequivalence between tablet/capsule and suspension formulation of cefixime, consideration needs to be given if the oral suspension is to be substituted for the tablet/capsule. This study is designed to assess whether test SKF101804 cefixime 400 milligrams (mg) capsule is bioequivalent to reference cefixime 400 mg capsule under fasting conditions in healthy adults. Subjects will be randomized in crossover manner to receive single oral doses of treatment A (SKF101804 cefixime test capsules) and treatment B (reference cefixime capsules), followed by a washout period of 7-14 days. Approximately 26 subjects will be included in the study and total duration in the study for each subject will be approximately 5 to 7 weeks.
Interventions
SKF101804/cefixime test capsule will be given with a single dose of 400 mg administered orally along with 240 mL of water. It will be available as a dark purple head and off white body locking type capsule with GSK' printed on cap and 400MG printed on body of capsule.
Cefixime reference capsule will be given with a single dose of 400 mg administered orally along with 240 mL of water. It will be available as red/orange hard gelatin size 0 capsule with Cefspan 400 mg printed on body of capsule.
