Do you know that Govt. of India has initiated a new scheme (see details at janaushadhi.gov.in) for manufacture and sale of generic medicines for diabetes (and many others). These are manufactured by top companies and sold at a very cheap price in govt. owned medicine shops. The rates are as following:
a. Metformin Hydrochlorides :Rs.7.72 per strip of 10 tablets of 1000 mg., Rs.6.03 per strip of 10 tablets of 500 mg.
b. Glimperide :Rs.11.81 per strip of 10 tablets of 2 mg., Rs.7.87 per strip of 10 tablets of 1 mg.
c. Glibenclamide: Rs. 1.38, 2.03, 2.68 and 3.96 per strip of 10 of 1.25, 2.5, 5.0 and 10 mg. respectively
However these are not available in formulations and also in sustained release type.
I have been using these and found them as good as branded ones.
If you want to try / buy these but do not have a janaushadhi shop near you, I can help as there is one in my city. Please contact me by email anilsaxena99@gmail.com
