Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Chronic Stable Angina
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Drug:NicorandilPatients would be advised 10mg bd nicorandil for the first seven days. Drug will be titrated to 20 mg bd after one week, atenolol 50 mg will be given along with nicorandil from day 1
Drug:AtenololPatients in the control arm would be advised atenolol 50 mg od
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
Nicorandil test armNicorandil is given with atenolol therapy.
Atenolol control armAtenolol 50 mg OD is given.
