What Is The Difference Between R Cin 600 And R Cinex 600 And Can I Switch From One Medicine To The Other?

Hello Doctor, My doctor prescribed me R cinex 600 and the pharmacist gave me R cinex 600 tablet. I was using R cinex 600 about 50 days. Dr advise me continue 4 month. But later another pharmacist gave me R cin 600 capsule. What is the difference between R cin 600 and Rcinex 600? Can I take R cix 600. Please help me out. Thank you
