Summary

Obstructive sleep apnoea syndrome (OSAS) is characterised by repeated episodes of upper airway occlusion during sleep.It can cause cycles of hypoxia reoxygenation. And it was postulated that intermittent hypoxia seems to resemble ischemia-reperfusion.Many study suggest that ischemia-reperfusion represents an oxidative stress causing increased generation of reactive oxygen species, especially superoxide anions.It is one of the most important mechanisms of cardiovascular diseases, including hypertension, coronary artery disease and cerebrovascular accident complication with OSAS.So many individuals approve OSAS is an Oxidative Stress disease.

Continuous positive airway pressure (CPAP) is the first-line of treatment method in moderate/severe OSA.But poor adherence to CPAP treatment is very common.The failure rate with CPAP treatment is more than 50%.So we are searching a new treatment for that patients. Carbocysteine is a antioxidant.It can not only scavenges the free radicals but also replenishes glutathione(GSH)which is has double antioxidant capacity. However, Carbocysteine is cheaper than other which has double antioxidant capacity drugs,such as N-acetylcysteine.The purpose is to evaluate efficacy of oral intake of Antioxidant Carbocysteine witch can reduce oxidative stress and improve the symptom of OSAS.It recover the imbalance in the oxidant-anti-oxidant status may reduce cardiovascular abnormalities in Patients with OSAS.

Conditions

  • Obstructive Sleep Apnoea

Interventions

DRUG

Carbocysteine

carbocisteine (2×250 mg, three times daily) for 6 weeks. The tablets are provided by Baiyunshan Pharmaceutical, China. patients will interviewed after 3 weeks to check their adherence to the study regimen by collecting and counting the number of remaining tablets, record adverse events, and refill study tablets for the next 3 weeks.

DEVICE

Continuous Positive Airway Pressure

Patients will interviewed after 3 weeks and the end of trial.We will check their compliance to device memory download , record adverse events and pressure .
