Hi John,
I'm sorry, I do not know how you could purchase this from an online website.
I have had some interaction with an organisation, based in Delhi,India, which deals in importing lifesaving onco drugs to India, their website also mentions that they deal in Indian generics probably for the international market.

You could send an enquiry. This may be more reliable than an online purchase.
Hope this helps. All the Best!!
