Hello Aspirant,

Pharmacology is my favorite subject and i could tell you that it's very interesting when you have proper grip in Anatomy, physiology and pathophysiology in a proper way,
First start with system wise preparation ,
Like
Cardiovascular system drugs,
Central nervous system ,
Autonomic nervous system ,
Drugs acting on peripheral nervous system,
Hormones and related drugs ,
Drugs acting on kidneys,
Gastrointestinal drugs,
Antibacterial and antifungals and so on....

So in this way if you study about drugs in a system wise then it will become more interesting and easier for you to learn and remember the concepts easily ,

For pharmacology you can refer the KD. TRIPATHI book,
Pharmacology by katzung ,
Pharmacotherapy by Ravi shankar ,

The above mentioned 3 books are good to learn and also understand concepts properly ,

I hope the above information is useful to you,

Good luck ,


All the best !
