What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Guanxin Shutong CapsuleDrug
3 capsules three times a day; Duration: 4 weeks. Number of Cycles: until progression or unacceptable toxicity develops.
Placebo CapsuleDrug
3 capsules three times a day; Duration: 4 weeks.
nitroglycerineDrug
Adults: 0.25mg-0.5mg (half pill or 1 pill) once, sub-lingual. One more pill per 5 minutes untill pain relief. If total dose is 3 pills in 15 minutes and the pain is still in, please seek medical advice urgently.
The participators in both arms who have agina symptom will take Nitroglycerine. So the accumulated consumption of participators is the one of the maesuremnts.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Guanxin Shutong Capsule and nitroglycerine in people with Angina, Stable, run by Shaanxi Buchang Pharmaceutical Co., Ltd at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: status not confirmed, as of the sponsor's last update on 3 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
