Hey Pratham,
Hope you are fine,
As you have mentioned in the question, A little bit of quiet difference in the courses you have already mentioned in the question.
BSc. IT is a bachelor's degree ( Bachelor of Science in Information technology field) while D. Pharmacy is a diploma course duration is 2 years. Yes, you can do D.pharma after this.
Hope it might be helpful to you...
Thank you.
