Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This multi-center, randomized controlled study aims to evaluate the effects of pentoxifylline on proteinuria in Korean type 2 diabetic patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators will recruit adults patients with type 2 diabetes aged over 20 years with spot urine albumin to creatinine ratio over 30mg/g in two consecutive measurements.

Enrolled patients will be randomly assigned to receive pentoxifylline (400mg three times daily) or placebo for 24 weeks.

Fasting blood and spot urine will be collected at baseline, 12 weeks and 24 weeks.

The investigators will evaluate the impact of pentoxifylline on proteinuria in type 2 diabetic patients.
