ABSTRACT

Objective:

To study the relationship between CYP2D6*10 gene polymorphism and metoprolol therapeutic effect for hypertension.

Methods:

A total of 60 patients with essential hypertension (EH) received metoprolol 47.5mg/d for 3d. After 3d the plasma metoprolol concentration after oral 2h was measured. Polymorphism of CYP2D6*10 gene was detected by PCR-RFLP. According to results of gene detection, the patients were divided into CC genotype group (wild type homozygote, fast metabolism type, n=14), CT genotype group (heterozygous mutation, intermediate metabolism type, n=25) and TT genotype group (homozygous mutation, slow metabolism, n=19). Metoprolol dosage was adjusted according to CYP2D6*10 genotype. After one week, plasma concentration of metoprolol after oral 2h was measured again, and mean heart rate and blood pressure were measured before and after gene-directed therapy.

Results:

Before gene-directed therapy, compared with CC and CT group there was significant increase in plasma concentration of metoprolol [(26.57±19.40) ng/ml vs. (23.88±12.86) ng/ml vs. (64.74±32.94) ng/ml, P0.05 all; Compared with before gene-directed therapy, there was significant increase in plasma concentration of metoprolol, and significant decrease in mSBP, mDBP and mHR in CC group (P0.05).

Conclusion:

CYP2D6*10 gene polymorphism affects metoprolol metabolism and its therapeutic effect on hypertension, gene-directed therapy can significantly improve drug therapeutic effect and reach ideal therapeutic goal in short time.
