Severe skin reactions include erythema multiforme, acute systemic eruption impetigo, Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reactions with eosinophilia and systemic symptoms. The clinical study is a single-center, randomized, open, single-dose trial design. The clinical study plans to enroll 30 subjects to evaluate the incidence and severity of pain and pruritus after a single skin test in healthy subjects. A total of 30 subjects were randomly divided into 2 groups with 15 cases in each group. Erythromycin or azithromycin skin test will be performed on the left hand, and the same amount of normal saline will be injected into the right hand as the control. This clinical observation experiment helps improve the side effects and promotes upgrading macrolide antibiotics during clinical application.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'The study is conducted in healthy adults aged 18-65 years， and there is no gender restriction for the subjects.', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n* The age range of the subjects is from 18 to 65 years old, and there is no gender restriction for the subjects;\n* Male subjects weigh more than 50kg (including 50kg) and female subjects weigh more than 45kg (including 45kg);
