hi,

see you may apply for gate exam from any of the stream, irrespective of your bachelors course stream, you have to self study for that particular gate syllabus and appear in exam, but based on gate exam m.tech admission and psu hiring is done. in some of the stream m.tech admission, it is required to pass bachelors in the specified stream.

however there is no paper of pharmaceutical technology in gate , upto 2021 gate syllabus. you may chose any other stream as per comparing the syllabus.

however I would suggest you to apply for engineering sciences, however you should consult with the faculty member to get their suggestion as well.

I have given a link to gate brochure, you may check it and go through the syllabus|:

Hello,

You can do Mtech in pharmaceutical technology or chemical engineering. Because you are doing BTech in pharmaceutical technology so you are good in medicine related Technology. So you can go for this branches. And if you give GATE examination then after qualifying you are eligible for Mtech.

All the best.
