Study: NCT02376088

Intervention type: DRUG
Intervention: Methimazole
Description: All enrolled subjects with GD were treated with methimazole. The initial dose for the GA1 and GB1 sungroups were 30 mg/d (10 mg, tid), TH levels were tested every month, and the dose was titrated accordingly over a period of 2-3 months, the dose was then decreased to 15-20 mg/d and thyroid function was monitored periodically until it eventually reached the maintenance dose of 2.5 mg-5.0 mg/d. The dose and adjustment method for GA2 and GB2 were the same with GA1 and GB1, while the dose for GA3 and GB3 was gradually decreased to 2.5-5.0 mg/d. All subjects underwent a treatment course over a period of 6 months.
