I don't know. Ask your doctor if Big Pharma is right for you.
I have been on (and off of) a number of heart medications over the past eight years or so, all of which were prescribed by my cardiologist. With rare exceptions, none of them would exist if "Big Pharma" had not invested in research and waded through the regulatory mire to get them approved. Should we begrudge them a profit?
Now if they knowingly suppress a substance or procedure that would be effective but render one of their products unnecessary (example: chelation therapy to remove plaque from arteries, so no need for statins, of which they sell megatons), that would need to be addressed. But if there is little or no profit to be made, why bother?
