Pharmacist

A pharmacist, also known as a chemist in Commonwealth English, is a healthcare professional who is knowledgeable about preparation, mechanism of action, clinical usage and legislation of medications in order to dispense them safely to the public and to provide consultancy services. A pharmacist also often serves as a primary care provider in the community and offers services, such as health screenings and immunizations.

Pharmacists undergo university or graduate-level education to understand the biochemical mechanisms and actions of drugs, drug uses, therapeutic roles, side effects, potential drug interactions, and monitoring parameters. In developing countries, a diploma course from approved colleges qualifies one for pharmacist role. This is mated to anatomy, physiology, and pathophysiology. Pharmacists interpret and communicate this specialized knowledge to patients, physicians, and other health care providers.

Among other licensing requirements, different countries require pharmacists to hold either a Bachelor of Pharmacy, Master of Pharmacy, or a Doctor of Pharmacy degree.

The most common pharmacist positions are that of a community pharmacist (also referred to as a retail pharmacist, first-line pharmacist or dispensing chemist), or a hospital pharmacist, where they instruct and counsel on the proper use and adverse effects of medically prescribed drugs and medicines. In most countries, the profession is subject to professional regulation. Depending on the legal scope of practice, pharmacists may contribute to prescribing (also referred to as "pharmacist prescribers") and administering certain medications (e.g., immunizations) in some jurisdictions. Pharmacists may also practice in a variety of other settings, including industry, wholesaling, research, academia, formulary management, military, and government.

Historically, the fundamental role of pharmacists as a healthcare practitioner was to check and distribute drugs to doctors for medication that had been prescribed to patients. In more modern times, pharmacists advise patients and health care providers on the selection, dosages, interactions, and side effects of medications, and act as a learned intermediary between a prescriber and a patient. Pharmacists monitor the health and progress of patients to ensure the safe and effective use of medication. Pharmacists may practice compounding; however, many medicines are now produced by pharmaceutical companies in a standard dosage and drug delivery form. In some jurisdictions, pharmacists have prescriptive authority to either independently prescribe under their own authority or in collaboration with a primary care physician through an agreed upon protocol called a collaborative practice agreement.

Increased numbers of drug therapies, aging but more knowledgeable and demanding populations, and deficiencies in other areas of the health care system seem to be driving increased demand for the clinical counseling skills of the pharmacist. One of the most important roles that pharmacists are currently taking on is one of pharmaceutical care. Pharmaceutical care involves taking direct responsibility for patients and their disease states, medications, and management of each to improve outcomes. Pharmaceutical care has many benefits that may include but are not limited to: decreased medication errors; increased patient compliance in medication regimen; better chronic disease state management, including hypertension and other cardiovascular disease risk factors; strong pharmacist–patient relationship; and decreased long-term costs of medical care.

Pharmacists are often the first point-of-contact for patients with health inquiries. Thus pharmacists have a significant role in assessing medication management in patients, and in referring patients to physicians. These roles may include, but are not limited to:

The role of pharmacy education, pharmacist licensing, and continuing education vary from country to country and between regions/localities within countries. In most countries, pharmacists must obtain a university degree at a pharmacy school or related institution, and/or satisfy other national/local credentialing requirements. In many contexts, students must first complete pre-professional (undergraduate) coursework, followed by about four years of professional academic studies to obtain a degree in pharmacy (such as Doctorate of Pharmacy). In the European Union, pharmacists are required to hold a Masters of Pharmacy, which allows them to practice in any other E.U. country, pending professional examinations and language tests in the country in which they want to practice. Pharmacists are educated in pharmacology, pharmacognosy, chemistry, organic chemistry, biochemistry, pharmaceutical chemistry, microbiology, pharmacy practice (including drug interactions, medicine monitoring, medication management), pharmaceutics, pharmacy law, pathophysiology, physiology, anatomy, drug delivery, pharmaceutical care, nephrology, hepatology, and compounding of medications. Additional curriculum may cover diagnosis with emphasis on laboratory tests, disease state management, therapeutics and prescribing (selecting the most appropriate medication for a given patient).
