The boundaries between these disciplines and with other sciences, such as biochemistry, are not always clear-cut.
Often, collaborative teams from various disciplines (pharmacists and other scientists) work together toward the introduction of new therapeutics and methods for patient care. However, pharmacy is not a basic or biomedical science in its typical form. Medicinal chemistry is also a distinct branch of synthetic chemistry combining pharmacology, organic chemistry, and chemical biology.

Those who wish to practice both pharmacy (patient-oriented) and pharmacology (a biomedical science requiring the scientific method) receive separate training and degrees unique to either discipline.
Pharmacoinformatics is considered another new discipline, for systematic drug discovery and development with efficiency and safety.
Pharmacogenomics is the study of genetic-linked variants that effect patient clinical responses, allergies, and metabolism of drugs.

Pharmacy support staff
Pharmacy technicians
Pharmacy technicians support the work of pharmacists and other health professionals by performing a variety of pharmacy-related functions, including dispensing prescription drugs and other medical devices to patients and instructing on their use. They may also perform administrative duties in pharmaceutical practice, such as reviewing prescription requests with medic's offices and insurance companies to ensure correct medications are provided and payment is received.
Legislation requires the supervision of certain pharmacy technician's activities by a pharmacist. The majority of pharmacy technicians work in
community pharmacies. In hospital pharmacies, pharmacy technicians may be managed by other senior pharmacy technicians. In the UK the role of a PhT in hospital pharmacy has grown and responsibility has been passed on to them to manage the pharmacy department and specialized areas in pharmacy practice allowing pharmacists the time to specialize in their expert field as medication consultants spending more time working with patients and in research. Pharmacy technicians are registered with the General Pharmaceutical Council (GPhC). The GPhC is the regulator of pharmacists, pharmacy technicians, and pharmacy premises.
In the US, pharmacy technicians perform their duties under the supervision of pharmacists. Although they may perform, under supervision, most dispensing, compounding and other tasks, they are not generally allowed to perform the role of counseling patients on the proper use of their medications. Some states have a legally mandated
pharmacist-to-pharmacy technician ratio The pharmacist-to-pharmacy technician ratio is a legal regulation that establishes the maximum number of pharmacy technicians that may be supervised by a licensed pharmacist at one given time. For example, a pharmacist-to-pharmacy technician ratio ...

Dispensing assistants
Dispensing assistants are commonly referred to as "dispensers" and in community pharmacies perform largely the same tasks as a pharmacy technician. They work under the supervision of pharmacists and are involved in preparing (dispensing and labelling) medicines for provision to patients.
Healthcare assistants/medicines counter assistants
In the UK, this group of staff can sell certain medicines (including pharmacy only and general sales list medicines) over the counter. They cannot prepare prescription-only medicines for supply to patients.

Hospital pharmacies can often be found within the premises of the hospital. Hospital pharmacies usually stock a larger range of medications, including more specialized medications, than would be feasible in the community setting. Most hospital medications are unit-dose, or a single dose of medicine. Hospital pharmacists and trained pharmacy technicians compound sterile products for patients including

s and other healthcare professionals to improve pharmaceutical care. Clinical pharmacists are now an integral part of the interdisciplinary approach to patient care. They often participate in patient care rounds for drug product selection. In the UK clinical pharmacists can also prescribe some medications for patients on the
National Health Services (NHS) or privately, after completing a non-medical prescribers course to become an Independent Prescriber.
The clinical pharmacist's role involves creating a comprehensive drug therapy plan for patient-specific problems, identifying goals of therapy, and reviewing all prescribed medications prior to dispensing and administration to the patient. The review process often involves an evaluation of the appropriateness of drug therapy (e.g., drug choice, dose, route, frequency, and duration of therapy) and its efficacy. Research shows that pharmacist led strategies reduce errors related to medication use. The pharmacist must also consider potential drug interactions, adverse drug reactions, and patient drug allergies while they design and initiate a drug therapy plan.
Ambulatory care pharmacy
Since the emergence of modern clinical pharmacy, ambulatory care pharmacy practice has emerged as a unique pharmacy practice setting. Ambulatory care pharmacy is based primarily on pharmacotherapy services that a pharmacist provides in a clinic. Pharmacists in this setting often do not dispense drugs, but rather see patients in-office visits to manage chronic disease states.
In the U.S. federal health care system (including the VA, the Indian Health Service, and
National Institute of Health (NIH)) ambulatory care pharmacists are given full independent prescribing authority. In some states, such as

, these pharmacist clinicians are given collaborative prescriptive and diagnostic authority. In 2011 the board of Pharmaceutical Specialties approved ambulatory care pharmacy practice as a separate board certification. The official designation for pharmacists who pass the ambulatory care pharmacy specialty certification exam will be Board Certified Ambulatory Care Pharmacist and these pharmacists will carry the initials BCACP.
Compounding pharmacy/industrial pharmacy
Compounding involves preparing drugs in forms that are different from the generic prescription standard. This may include altering the strength, ingredients, or dosage form. Compounding is a way to create custom drugs for patients who may not be able to take the medication in its standard form, such as due to an allergy or difficulty swallowing. Compounding is necessary for these patients to still be able to properly get the prescriptions they need.
One area of compounding is preparing drugs in new dosage forms. For example, if a drug manufacturer only provides a drug as a tablet, a compounding pharmacist might make a medicated
lollipop

that contains the drug. Patients who have difficulty swallowing the tablet may prefer to suck the medicated lollipop instead.
Another form of compounding is by mixing different strengths (g, mg, mcg) of capsules or tablets to yield the desired amount of medication indicated by the

clinical pharmacist practitioner. This form of compounding is found at community or hospital pharmacies or in-home administration therapy.
Compounding pharmacies specialize in compounding, although many also dispense the same non-compounded drugs that patients can obtain from community pharmacies.
Consultant pharmacy
Consultant pharmacy practice focuses more on medication regimen review (i.e. "cognitive services") than on actual dispensing of drugs. Consultant pharmacists most typically work in

s, but are increasingly branching into other institutions and non-institutional settings. Traditionally consultant pharmacists were usually independent business owners, though in the United States many now work for a large pharmacy management company such as
Omnicare,
Kindred Healthcare or
PharMerica. This trend may be gradually reversing as consultant pharmacists begin to work directly with patients, primarily because many elderly people are now taking numerous medications but continue to live outside of institutional settings. Some community pharmacies employ consultant pharmacists and/or provide consulting services.
The main principle of consultant pharmacy was developed by Hepler and Strand in 1990.
Veterinary pharmacy
Veterinary pharmacies, sometimes called ''animal pharmacies'', may fall in the category of hospital pharmacy, retail pharmacy or mail-order pharmacy. Veterinary pharmacies stock different varieties and different strengths of medications to fulfill the pharmaceutical needs of animals. Because the needs of animals, as well as the regulations on

, are often very different from those related to people, in some jurisdictions veterinary pharmacy may be kept separate from regular pharmacies.
Nuclear pharmacy
Nuclear pharmacy focuses on preparing radioactive materials for diagnostic tests and for treating certain diseases. Nuclear pharmacists undergo additional training specific to handling radioactive materials, and unlike in community and hospital pharmacies, nuclear pharmacists typically do not interact directly with patients.
Military pharmacy

Military pharmacy is a different working environment to civilian practise because military pharmacy technicians perform duties such as evaluating medication orders, preparing medication orders, and dispensing medications. This would be illegal in civilian pharmacies because these duties are required to be performed by a licensed registered pharmacist. In the US military, state laws that prevent technicians from counseling patients or doing the final medication check prior to dispensing to patients (rather than a pharmacist solely responsible for these duties) do not apply.
Pharmacy informatics
Pharmacy informatics is the combination of pharmacy practice science and applied information science. Pharmacy informaticists work in many practice areas of pharmacy, however, they may also work in information technology departments or for
healthcare information technology vendor companies. As a practice area and specialist domain, pharmacy informatics is growing quickly to meet the needs of major national and international patient information projects and health system interoperability goals. Pharmacists in this area are trained to participate in medication management system development, deployment, and optimization.
Specialty pharmacy
Specialty pharmacies supply high-cost injectable, oral, infused, or inhaled medications that are used for chronic and complex disease states such as cancer, hepatitis, and rheumatoid arthritis. Unlike a traditional community pharmacy where prescriptions for any common medication can be brought in and filled, specialty pharmacies carry novel medications that need to be properly stored, administered, carefully monitored, and clinically managed. In addition to supplying these drugs, specialty pharmacies also provide lab monitoring, adherence counseling, and assist patients with cost-containment strategies needed to obtain their expensive specialty drugs. In the US, it is currently the fastest-growing sector of the pharmaceutical industry with 19 of 28 newly
Food and Drug Administration (FDA) approved medications in 2013 being specialty drugs.
Due to the demand for clinicians who can properly manage these specific patient populations, the Specialty Pharmacy Certification Board has developed a new certification exam to certify specialty pharmacists. Along with the 100 questions computerized multiple-choice exam, pharmacists must also complete 3,000 hours of specialty pharmacy practice within the past three years as well as 30 hours of specialty pharmacist continuing education within the past two years.

, and lowers costs, while the opposite causes those things. Research in various places reports mixed outcomes in different circumstances.
Environmental impacts
In 2022 the
Organisation for Economic Co-operation and Development (OECD) proposed that pharmaceutical companies should be required to collect and destroy unused or expired medicines that they have put on the market in order to reduce public health risks around the misuse of medicines obtained from waste bins, the development of antimicrobial resistant bacteria from the discharge of antibiotics into environmental systems and "economic losses" from wasted healthcare resources. Potentially harmful concentrations of pharmaceutical waste has been detected in more than a quarter of water samples taken from 258 rivers around the world. OECD recommend that medicines should be collected separately from household waste and that "marketplaces and redistribution platforms for unused close-to-expiry-date medicines" should be set up. Such extended producer responsibility schemes are already running in France, Spain and Portugal.
The future of pharmacy

. Rather than simply dispensing medication, pharmacists are increasingly expected to be compensated for their patient care skills. In particular,
Medication Therapy Management (MTM) includes the clinical services that pharmacists can provide for their patients. Such services include a thorough analysis of all medication (
prescription, non-prescription, and herbals) currently being taken by an individual. The result is a reconciliation of medication and patient education resulting in increased patient health outcomes and decreased costs to the health care system.
This shift has already commenced in some countries; for instance, pharmacists in

National Institute for Health (NIH) shows "pharmacy based interventions improved patients' medication adherence rates by 2.1 percent and increased physicians' initiation rates by 38 percent, compared to the control group".
