ABSTRACT
Objective To evaluate the safety and efficiency of combined finasteride and metformin on benign prostatic hyperplasia (BPH) with type 2 diabetes mellitus(T2DM).Methods Totally 106 patients with BPH plus T2DM received finasteride and metformin treatment for over 12months.Before and after treatment,the side effects and following parameters were measured:prostatic volume (PV),prostate-specific antigen(PSA),international prostate symptom score (IPSS),quality of life (QOL),the maximum flow rate of urinary (Qmax),residual urine(RU),body mass index (BMI),cholesterol (TG).Results There were obvious changes in the following:PV decreased from (56.40±18.75)ml to(42.40± 19.68) ml,PSA decreased from(3.65± 1.08) μg/L to (1.76±0.66)μg/L,IPSS decreased from(22.58±9.45)to(16.67±7.56),QOL decreased from(4.22± ±0.87) to (2.36 ± 0.74),Qmax increased from(8.32±2.42)ml/s to(15.48±3.61)ml/s,RU decreased form(68.36±19.25)ml to(36.42±13.91)ml,BMI decreased from(28.52±3.73)kg/m2 to (19.76± 1.88)kg/m2,TG decreased from (2.52 ± 0.43) mmol/L to (1.38 ± 0.52) mmol/L.The changes of PV,PSA,IPSS,QOL,Qmax,RU,BMI and TG were statistically significant (all P＜0.05).Conclusions Long term combined finasteride and metformin treatment for BPH plus T2DM is effective and safe.And the two drugs may be improve the efficacy each other.
