Pharmacy is the science and technique of preparing and dispensing drugs. It is a health profession that links health sciences with chemical sciences and aims to ensure the safe and effective use of pharmaceutical drugs.
Dispensing is the part of pharmacy practice in which a pharmacist supervises drug treatment of his/her patient.
The principal goal of pharmaceutical care is to achieve positive outcomes from the use of medication which improves patients’ quality of life with minimum risk. Pharmacists strive to:
- Eliminate or reduce symptoms
- Arrest or slow a disease process
- Prevent disease; Diagnose disease
- Alter physiological processes for desirable result in the patient’s health.
Role of a Pharmacist
"PHARMACISTS PLAY A VITAL ROLE IN THE HEALTH CARE SYSTEM THROUGH THE MEDICINE AND INFORMATION THEY PROVIDE."
While responsibilities vary among the different areas of pharmacy practice, the bottom line is that pharmacists help patients get well. Pharmacists practice in nearly all areas and specialties in healthcare – sometimes behind the scenes and not obvious to the public eye, but as the medication expert on the healthcare team, pharmacists are necessary in all facets of healthcare. Pharmacist responsibilities include a range of care for patients, from dispensing medications to monitoring patient health and progress to optimize their response to medication therapies. Pharmacists also educate patients on the use of prescriptions and over-the-counter medications, as well as provide population based care in institutional settings. Pharmacists educate and advise physicians, nurses, and other health professionals on medication therapy decisions. Pharmacists also provide expertise about the composition of drugs, including their chemical, biological, and physical properties and their manufacture and use. They ensure drug purity and strength and make sure that drugs do not interact in a harmful way. Pharmacists are medication experts ultimately concerned about their patients’ health and wellness.
Industrial Pharmacy. By definition Industrial Pharmacy is a discipline which includes manufacturing, development, marketing and distribution of drug products including quality assurance of these activities.
Importance and scope of Industrial Pharmacy
Industrial pharmacy is a complex, multi-factorial environment, with the overall aim of manufacturing, developing and marketing safe and efficacious medicines including quality assurance of these activities. Research in industrial pharmacy is done both locally and under the guidance of Faculty of Pharmacy. Industrial pharmacist is responsible for determining the medication developed by pharmaceutical companies have both right ingredient and correct amount of these ingredients. The pharmaceutical industry is made up of a large number of different areas which all form part of the journey of drug discovery to marketing and sales of a medicine. Pharmacists are in the fortunate position of being able to contribute professionally at almost any point along this journey Within every pharmaceutical company the regulatory affairs team support the progression of a drug product through from clinical studies, launch and post marketing and ensure that all means of advertisement and publicity regarding the product are compliant with the various regulatory bodies such as the Food and Drug Administration (FDA) and the Medicines and Healthcare Products Regulatory Agency (MHRA). Regulatory affairs teams also ensure that all intellectual property enclosing a product is adequately protected by patent laws and is competitive within the identified market. Many of the industrial pharmacists have not remained in one specific area of the pharmaceutical industry, rather they have utilised the ability to perform diverse roles and develop experience in all sectors. In the industrial sector the pharmacy qualification is of a quality superior to many other disciplines.
Physical pharmacy is a fundamental course that leads to proper understanding of subsequent courses in Pharmaceutics and pharmaceutical technology.
Physical pharmacy integrates knowledge of mathematics, physics and chemistry and applies them to the pharmaceutical dosage form development.
Basic Physical Pharmacy provides a thorough yet accessible overview of the principles of physical pharmacy and their application in drug formulation and administration. This definitive guide to physical pharmacy covers all types of pharmaceuticals, from traditional forms and dosages to nanotechnology-based novel dosage design.
Authored by two nationally recognized pharmaceutical scientists and active pharmacy faculty, Basic Physical Pharmacy is clearly organized into four sections: Physical Pharmacy in Solutions; Solid Dosage Forms; Polyphasic Systems; and Drug Delivery and Novel Drug Delivery Systems. Students can build upon their chemistry education to learn the physicochemical properties of drugs and their therapeutic effects on the body. With a highly accessible approach, Basic Physical Pharmacy will help students comprehend and apply the principles of physical pharmacy in clinical practice.
Covers major drug products and delivery systems
Features current trends in pharmaceutical research and development, including nanotechnology-based dosage design
Includes many examples of useful equations and formulation methods
Contains over 200 illustrations, photos, and tables
Biopharmaceutics examines the interrelationship of the physical/chemical properties of the drug, the dosage form (drug product) in which the drug is given, and the route of administration on the rate and extent of systemic drug absorption. The importance of the drug substance and the drug formulation on absorption, and in vivo distribution of the drug to the site of action, is described as a sequence of events that precede elicitation of a drug's therapeutic effect.
Despite the paucity of biopharmaceutic and pharmacokinetic data for many old drugs, these areas of scientific research have demonstrated an immense value in clinical medicine, and can be expected to expand man's knowledge of drug action and the influence of physiological function of drug disposition. Illustrated in this report are four major areas where biopharmaceutics and pharmaco-kinetics have contributed significantly to the field of medicine. Foremost among these contributions are: 1. the assessment of bioavailability and bioequivalence of new drugs and generic marketed drugs, respectively; 2. the pharmacolinetic characterization of new drugs and new drug delivery systems; 3. adjustment of dosing regimen; 4. assessment of kinetic profile of drugs in diseases state and dose adjustment thereof. Patient-drug pharmacokinetic profile designed to avoid toxicity is illustrated.
