I haven't done any research as to drugs coming from India, but I've read and saw a documentary indicating that they have excellent hospitals and doctors over there and surgeries and procedures (including rehab and aftercare) are performed for a fraction of the cost.
Having been to both private and government-run hospitals in India - I can tell you the documentary you saw is as truthful as Michael Moore selling us on the superiority of healthcare in Cuba.
Private hospitals are ala carte and you have to pay for your care in advance after paying bribes. Government hospitals are worse - with bribes required and wait times measured in entire days with care that is almost subhuman. I cannot even begin to describe what the government hospital in Kakinada was like without getting nauseous remembering it. The private hospital was a bit better and cleaner (by Indian standards) and while the cost of care is a fraction of what it is here (my wife's emergency room visit with IVs for vomiting and dehydration was only $35 US), but when it comes to major healthcare issues such as heart attack, you are into them for multiple thousands of dollars that have to be paid in advance of any treatment being administered to you.
Also, I noticed when living there, that the doctors tend to throw medicine at their many patients. A lot of diseases have become drug-resistant over there due to the over-prescribed antibiotics and other medicines, most of which we also discovered were frauds - sugar pills in cases that were listed to be blood thinners. Fraud is rampant there and hospital pharmacies tend to dish out the corruption as readily as a vendor on the street.
But if you have money - and will wave it around - and you can hide your caste if you are a dalit, you can get whatever you want to find in India.
