Check on medication

Hi 

My Dad has cancer of oesophagus and more recently diagnosed heart failure. Please can a nurse confirm whether he should be taking 10mg both these medications dapagliflozin and lisinopril. He does had diabetes which until the cancer symptoms kicked in he controlled with diet and exercise? 

We have appt with cardiology this week and I've asked gp when  called out to check him over last week plus hospice nurse today whether any issue on the two types of tablet to be taken?  

Thank you
