Brief Summary

The goal of this clinical trial is to learn if Gabapentin works to treat flushing/erythema associated with rosacea. It will also learn about the safety of drug Gabapentin. The main questions it aims to answer are:

• Does drug Gabapentin reduce flushing and erythema associated with rosacea?
• What medical problems do participants have when taking drug Gabapentin? Researchers will compare Gabapentin to a positive control (minocycline plus hydroxychloroquine, a first-line treatment for rosacea) to see if drug Gabapentin works to reduce flushing and erythema associated with rosacea

Conditions

Rosacea; Rosacea Subtype 1 (Erythematotelangiectatic)

Keywords

rosacea

Outcome Measures

Primary Outcomes (1)

• the score of CEA ( Clinician Erythema Assessment )

  The reduction of the CEA score was compared before treatment, 4 weeks and 8 weeks, 12 weeks after treatment. The CEA score was assessed by a scale, 0 = clear, 1= almost clear, 2 =Mild, 3= Moderate,4= Severe.

  4 weeks, 8 weeks, 12 weeks after treatment

Study Arms (3)

minocycline combined with hydroxychloroquine

EXPERIMENTAL

Drug: minocycline combined with hydroxychloroquine

gabapentin 300mg bid

ACTIVE COMPARATOR

Drug: gabapentin 300mg bid

gabapentin 300mg tid

ACTIVE COMPARATOR

Drug: gabapentin 300mg tid

Interventions

gabapentin 300mg bid DRUG

Patients with rosacea were collected and randomly divided into three groups for treatment, one group was treated with minocycline combined with hydroxychloroquine, one group was treated with gabapentin 300mg Bid, and the other group was treated with gabapentin 300mg tid. Before treatment, 4 weeks after treatment, and 8 weeks after treatment, the patient's condition score was statistically analyzed, and the efficacy and difference of each group were observed
