Try to find a developer who can help you merge pharmaceutical business in blockchain.
My idea would be to come up with my own tokens and reward each and every individual with some rebates over their spendings they would do with my tokens whether online (through pharmaceutical sites) or offline (hospitals and/or clinics). For that, you need to collaborate with a lot of people and make them understand the whole concept you have in your mind, then ask them whether they would be ready to support your project by accepting your tokens at their place? This will surely get you a lot of exposure. Don't forget to implement proper buyback schemes to keep your customers remain with you forever.
