Pharmacology

Both specializations have unique advantages. Pharmaceutics focuses on drug formulation, delivery systems, and manufacturing processes, while Pharmacology emphasizes drug action, clinical trials, and therapeutic outcomes.

If you are inclined toward research and drug production, Pharmaceutics is more suitable. On the other hand, if you aim to enter clinical research, regulatory roles, or test new drugs, Pharmacology might be a better choice. Your career goals should guide the decision.

Pharmaceutics focuses on formulation and design of drugs for masses also teaching students how to create effective medicines in different forms. 

But Pharmacology, on other hand, is study and not process. It is a study of how drugs affect and work with human body. 

Pharmacognosy is the study of medicinal drugs obtained from natural sources such as plants, animals, and minerals, focusing on their identification, extraction, and quality evaluation.

Pharmacology, in contrast, examines how drugs act on the body and their therapeutic applications. 

Pharmacovigilance primarily involves monitoring drug safety, adverse effects, and side effects. While they complement one another, each discipline serves a distinct role in pharmacy education and practice.

Pharmacognosy focuses on natural drug sources (mostly plants) and their medicinal properties, emphasizing the extraction and identification of bioactive molecules. However, Pharmacology is the study of drug effects on the body, and then Pharmaceutical Chemistry is the chemistry of turned into drugs, or the making of drugs and drug formulation. Consequently, Pharmacognosy connects nature to drug discovery, which makes it distinctive.

If you've done BHMS, you can usually apply for the Modern Pharmacology course no matter which state you're from. It's not strictly limited to those registered in Maharashtra. But, if the course is run by a Maharashtra-based institute, they might prefer candidates registered in the state. It's not the same everywhere, so it's better to directly ask the institute offering the course to be sure.
