This study will be an investigator-blinded, patient-blinded, assessor-blinded, parallel-group, randomized clinical trial. It aims to evaluate the efficacy of one-week twice-daily application of topical papaya leaf extract ointment compared to mupirocin ointment in achieving clinical cure among patients with impetigo.

Primary Outcome Measures:
  • Clinical clearance after 1 week of treatment [ Time Frame: 1 week ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • time to clinical clearance [ Time Frame: 1 week ] [ Designated as safety issue: No ]
  • score in the 6-point grading system [ Time Frame: 1 week ] [ Designated as safety issue: No ]

    The 6-point grading system will assess clinical response based on each of the following six paramaters. One point will be assigned for each of the following parameters present in a patient, with the maximum possible score on this grading system being 6. A patient need not satisfy all six parameters. A decrease in score on this grading system compared to baseline will indicate clinical improvement, while an increase in score will indicate clinical worsening.

    • erythema
    • edema
    • vesiculation
    • pustulation
    • crusting
    • scaling

  • change in size of lesion compared to baseline [ Time Frame: 1 week ] [ Designated as safety issue: No ]
  • presence or absence of recurrence on any part of the body 2 weeks after starting treatment [ Time Frame: 1 week ] [ Designated as safety issue: No ]
  • presence or absence of adverse events during treatment [ Time Frame: 1 week ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 128
Study Start Date: August 2013
Estimated Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)
