Need a pharmacy directory...

Hello everyone, I have been searching for a hospital directory for India but in vain. My sister who is an asthma patient and me are going to India on vacation and we fear that she may fall ill there and that’s why we are looking for a hospital directory in case she doesn’t feel well. Thus, I will then be able to locate the nearest pharmacy. Our parents are not coming with us.
While searching, I came across an India pharmacy directory on http://www.drugdelivery.ca/xx-...-and-Diu-Pharmacy.aspx where you can get the address and the phone number of the local pharmacies in India grouped by cities but I have no information on the hospitals there. Can someone please tell me where I can get the information I am looking for please?
