Looking at alternatives to clomiphene citrate treatment for women with polycystic ovary syndrome.
Experts have identified a drug that can effectively treat women with polycystic ovary syndrome (PCOS) who are resistant to clomiphene citrate (CC) therapy.
Almost a quarter of all women with PCOS fail to ovulate in response to CC treatment.
In the search for alternative drugs, recent attention has turned to those with insulin-sensitizing actions, such as metformin and N-acetyl cysteine.
Aboubakr Elnashar (Benha University Hospital) and team found that of these two drugs, only metformin effectively induced ovulation in women with PCOS who resisted CC treatment.
Sixty-one infertile women with PCOS were assigned to either 1500 mg/day metformin or 1.8 g/day N-acetyl cysteine, for 6 weeks.
Women receiving metformin experienced a significant decrease in fasting glucose and fasting insulin levels while women in the N-acetyl cysteine group experienced no such effects.
Ovulation was significantly better in women who took metformin, at 51.6 percent compared with 6.7 percent in those who took N-acetyl cysteine.
The scientists conclude: "Metformin alone is an effective drug for inducing ovulation in CC-resistant PCOS, whereas N-acetyl cysteine alone is not.
"N-Acetyl cysteine may be an adjuvant to CC, but not an alternative."
