Abbott Healthcare Pvt. Ltd — ppg 0.3 fragile medicine. but within expiry date

Address:

I bought PPG 0.3 on 2 sep 2017 from medicine shop, near Barasat station north 24 pgs. which showed batch number HTB0245 and MFG date NOV 2016 &exp date.. OCT 2018 but during consumption noticed that the tablet is fragile to some extent. Its a tablet for diabetes. and I took same medicine from same shop for last 2 years. I want to know is that medicine is genuine? what is my method of approach to get proper judgment. Thanks
