Brief Summary:

Polycystic ovary syndrome affects a striking 9-18% of Australian reproductive aged women and has been associated with a number of metabolic abnormalities.

Given the strong correlation between metabolic abnormalities and increased sympathetic activity, we hypothesise that reducing this activity using medication (moxonidine) can help improve the metabolic abnormalities, and therefore improve outcomes in polycystic ovary syndrome.

Arm Intervention/treatment
Active Comparator: Active Drug: Moxonidine
0.2 mg/day moxonidine for 2 weeks 0.4 mg/day moxonidine for 3 months

Placebo Comparator: Placebo Drug: Placebo
Encapsulated lactose powder

Primary Outcome Measures :
  1. Microneurography [ Time Frame: 3 months ]
    Microneurography is a technique developed to measure the sympathetic activitiy directly from the peroneal nerve. Microneurography will be performed at baseline visit and at 3 months follow up visit.

Secondary Outcome Measures :
  1. Blood biochemistry measurement [ Time Frame: 3 months ]
    To assess the metabolic function of the participants we will be drawing fasting blood samples for biochemical analysis. These test will be performed at baseline and 3 months follow up visit

  2. Oral glucose tolerance test [ Time Frame: 3 months ]
    A standard 75g glucose tolerance test will be performed. Venous blood will be taken before and 2 hours after the glucose drink was given.
