Pharmacology is that the scientific study of drug action on biological systems. It is the study of the interactions between a living organism and drugs, defined as the branch of medicine concerned with the uses, effects, and modes of action of drugs

Biopharmaceutical Science contains the study of the drug discovery and their development, and along with their properties, both physical and chemical. It conjointly deals with the biological effects of the medicine like onset and period of action beside their intensity within the body. Bio pharmaceutics facilitate in calculative the bio availability and therapeutic activity of the medicine within the body

Formulation studies involve developing a preparation of the drug which is both stable and acceptable to the patient. For orally administered drugs, this usually involves incorporating the drug into a tablet or a capsule. It is important to make the distinction that a tablet contains a variety of other potentially inert substances apart from the drug itself, and studies have to be carried out to ensure that the encapsulated drug is compatible with these other substances in a way that does not cause harm, whether direct or indirect.

Pharmacovigilance is also known as drug safety, and it is  the practice of monitoring the effects of medical drugs after they have been licensed for use, especially in order to identify and evaluate previously unreported adverse drug reactions

Ethno medicine is a study or comparison of the traditional medicine based on bioactive compounds in plants and animals and practiced by various ethnic groups, especially those with little access to western medicines, e.g., indigenous peoples. The word ethno medicine is sometimes used as a synonym for traditional medicine

Pharmaceutical analytical techniques explain the process or different processes to identify and quantify a substance, the components of a pharmaceutical solution or mixture or the determination of the structures of chemical compounds used in manufacturing of the pharmaceutical product. The components monitored include process impurities, chiral or achiral drugs, residual solvents, degradation products, excipients such as preservatives, extractable and leachable from container and closure or manufacturing process, pesticide in drug product from plant origin, and metabolites.

Pharmacoepidemiology is the study of the utilization and effects of drugs in large numbers of people; it provides an estimate of the probability of beneficial effects of a drug in a population and the probability of adverse effects. It can be called a bridge science spanning both clinical pharmacology and epidemiology. Pharmacoepidemiology concentrates on clinical patient outcomes from therapeutics by using methods of clinical epidemiology and applying them to understanding the determinants of beneficial and adverse drug effects, effects of genetic variation on drug effect, duration-response relationships, clinical effects of drug-drug interactions, and the effects of medication non-adherence.

Phytochemistry is in the study of phytochemicals in plants and other natural sources. Phytochemicals are chemicals derived from plants. In other words the terms are often used to describe the large number of primary and secondary metabolic compounds found in plants. Phytochemicals have properties such as protection against insect attacks and diseases. They also exhibit a number of protective functions for human beings also.

Pharmacogenomics is the study of how genes affect a person’s response to drugs. This relatively new field combines pharmacology (the science of drugs) and genomics (the study of genes and their functions) to develop effective, safe medications and doses that will be tailored to a person’s genetic makeup.

Analytical and Bio analytical Techniques in which it includes analytical methods used for the characterization, release, and stability testing for chemical compounds and for new drugs also as well as the biotechnological/biological products and related to sciences and pharma.

Healthcare Management may be a totally different system within the management trade. In which it deals with the various field about leadership, management, administration of hospitals, hospital networks, etc. in Hospital Management it is a facility that the services are provided to the hospitals and patients.

Industrial Pharmacy mainly deals with the drug research, design, development and also testing, treatments of new medicines, and more over ensuring safety and quality of drugs. And it includes areas relates to different functions in the pharmaceutical industry and having contact with the areas like engineering and economics.

Drug Regulatory Affairs refers to all aspects within the pharmaceutical development process and how they are subject to various degrees of regulation. The pharmaceutical law frame, guidelines covering Quality, Safety and Efficacy as well as Health Authorities' attitudes and requirements etc. have a great influence on the drug development process and the success of it. Regulatory affairs professionals deal with these aspects

Industrial property (IP) rights are extremely important for the pharmaceutical industry. The use of the IP system by SMEs in the pharmaceutical industry depends largely on the business strategy of a company, its size, resources, innovative capacity, competitive context and field of expertise. Research-based, innovation-led companies that seek to develop new drugs improve or adapt existing drugs or develop new pharmaceutical/medical equipment or processes, tend to rely heavily on the patent system to ensure they recover the investments incurred in research and development
