A medication is a drug used to diagnose, cure, treat, or prevent disease. Drug therapy (pharmacotherapy) is an important part of the medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate management.
A prescription drug is a pharmaceutical drug that is permitted to be dispensed only to those with a medical prescription. In contrast, over-the-counter drugs can be obtained without a prescription. The reason for this difference in substance control is the potential scope of misuse, from drug abuse to practicing medicine without a license and without sufficient education. Different jurisdictions have different definitions of what constitutes a prescription drug.
The pharmaceutical industry is an industry in medicine that discovers, develops, produces, and markets pharmaceutical drugs for use as medications to be administered to patients, with the aim to cure and prevent diseases, or alleviate symptoms. Pharmaceutical companies may deal in generic or brand medications and medical devices. They are subject to a variety of laws and regulations that govern the patenting, testing, safety, efficacy using drug testing and marketing of drugs. The global pharmaceuticals market produced treatments worth $1,228.45 billion in 2020 and showed a compound annual growth rate (CAGR) of 1.8%.
Pharmacovigilance, also known as drug safety, is the pharmaceutical science relating to the "collection, detection, assessment, monitoring, and prevention" of adverse effects with pharmaceutical products. The etymological roots for the word "pharmacovigilance" are: pharmakon and vigilare. As such, pharmacovigilance heavily focuses on adverse drug reactions (ADR), which are defined as any response to a drug which is noxious and unintended, including lack of efficacy. Medication errors such as overdose, and misuse and abuse of a drug as well as drug exposure during pregnancy and breastfeeding, are also of interest, even without an adverse event, because they may result in an adverse drug reaction.
An essential medicines policy is one that aims at ensuring that people get good quality drugs at the lowest possible price, and that doctors prescribe the minimum of required drugs in order to treat the patient's illness. The pioneers in this field were Sri Lanka and Chile.
The Sri Lanka National Pharmaceuticals Policy was established in the 1970s following the submission of a report by Dr S.A. Wickremasinghe and Prof. Seneka Bibile. It aimed at ensuring that people get good quality drugs at the lowest possible price and that doctors would prescribe the minimum required drugs to treat the patient's illness. It was a pioneer in the field of rational National pharmaceuticals policy.
Essential medicines, as defined by the World Health Organization (WHO), are the medicines that "satisfy the priority health care needs of the population". These are the medications to which people should have access at all times in sufficient amounts. The prices should be at generally affordable levels. Since 1977, the WHO has published a model list of essential medicines, with the current (2019) list for adult patients containing over 400 medicines. Since 2007, a separate list of medicines intended for child patients has been published. Both the WHO adult and children's lists contain a notation indicating that a particular medication is "complementary", thus essentially there are two lists, the "core list" and the "complementary list". The core list presents a list of minimum medicine needs for a basic health care system, listing the most efficacious, safe and cost-effective medicines for priority conditions. Priority conditions are selected on the basis of current and estimated future public health relevance, and potential for safe and cost-effective treatment. The complementary list presents essential medicines for priority diseases, for which specialized diagnostic or monitoring facilities are needed. In case of doubt medicines may also be listed as complementary on the basis of higher costs or less attractive cost-effectiveness in a variety of settings. The list is important because it forms the basis of national drugs policy in more than 155 countries, both in the developed and developing world. Many governments refer to WHO recommendations when making decisions on health spending. Countries are encouraged to prepare their own lists taking into consideration local priorities. Over 150 countries have published an official essential medicines list.
The pharmaceutical industry in Bangladesh is one of the most developed technology sectors within the country. Manufacturers produce insulin, hormones, and cancer drugs. This sector provides 97% of the total medicinal requirement of the local market. The industry also exports medicines to global markets, including Europe. Pharmaceutical companies are expanding their business with the aim to expand the export market.
Many developing nations have developed national drug policies, a concept that has been actively promoted by the WHO. For example, the national drug policy for Indonesia drawn up in 1983 had the following objectives:
Pharmaceutical policy is a branch of health policy that deals with the development, provision and use of medications within a health care system. It embraces drugs, biologics, vaccines and natural health products.
The Ministry of Chemicals and Fertilizers in India is the federal ministry with administrative purview over three departments namely:
Pharmacy in China involves the activities engaged in the preparation, standardization and dispensing of drugs, and its scope includes the cultivation of plants that are used as drugs, the synthesis of chemical compounds of medicinal value, and the analysis of medicinal agents. Pharmacists in China are responsible for the preparation of the dosage forms of drugs, such as tablets, capsules, and sterile solutions for injection. They compound physicians', dentists', and veterinarians' prescriptions for drugs. Pharmacological activities are also closely related to pharmacy in China.
A formulary is a list of pharmaceutical drugs, often decided upon by a group of people, for various reasons such as insurance coverage or use at a medical facility. Traditionally, a formulary contained a collection of formulas for the compounding and testing of medication. Today, the main function of a prescription formulary is to specify particular medications that are approved to be prescribed at a particular hospital, in a particular health system, or under a particular health insurance policy. The development of prescription formularies is based on evaluations of efficacy, safety, and cost-effectiveness of drugs.
The Ministry of National Health Services, Regulation and Coordination is a cabinet level ministry of the government of Pakistan with responsibility for national public health.
