Detailed Clinical Trial Description
In combined NAC-CC group group,patients received NAC (200 mg per sachet, SEDICO, Egypt) for 5-6 weeks from the 1st day of of spontaneous or induced menstruation (in a dose of 1.8 g orally in three divided doses, 3 sachets per dose). All patients in other group received metformin HCl (Cidophage®; Chemical Industries Development, Egypt), 500 mg thrice daily for 5-6 weeks from the 1st day of spontaneous or induced menstruation. Then after the end of this period, patients in either group received 100 mg CC (Clomid®; Global Napi Pharmaceuticals,Cairo, Egypt) for 5 days starting from day 3 of spontaneous or induced menstruation. With persistent anovulation, it was increased by 50 mg for the next cycle.
Patients continued treatment for three successive cycles using the same protocol. NAC and metformin were stopped only when pregnancy was documented.
Intervention(s) in this Clinical Trial
- Drug: combined N-acetyl cysteine -CC
- N-acetyl cysteine(1.8 g orally daily)for 5-6 weeks from the 1st day of spontaneous or induced menstruation followed by 100 mg CC for 5 days from day 3 of spontaneous or induced menstruation. With persistent anovulation,CC increased by 50 mg for the next cycle. Treatment continued for three successive cycles
- Drug: combined metformin-CC
- Patients received metformin HCl (1500 mg daily) for 5-6 weeks from the 1st day of spontaneous or induced menstruation, followed by 100 mg CC for 5 days starting from day 3 of spontaneous or induced menstruation. With persistent anovulation,CC increased by 50 mg for the next cycle. Treatment continued for three successive cycles
Arms, Groups and Cohorts in this Clinical Trial
- Experimental: combined N-acetyl cysteine - CC
- N-acetyl cysteine(1.8 g orally daily)for 5-6 weeks from the 1st day of spontaneous or induced menstruation followed by 100 mg CC for 5 days from day 3 of spontaneous or induced menstruation. With persistent anovulation,CC increased by 50 mg for the next cycle. Treatment continued for three successive cycles
- Active Comparator: combined metformin-CC
- Patients received metformin HCl (1500 mg daily) for 5-6 weeks from the 1st day of spontaneous or induced menstruation, followed by 100 mg CC for 5 days starting from day 3 of spontaneous or induced menstruation. With persistent anovulation,CC increased by 50 mg for the next cycle. Treatment continued for three successive cycles.
