1 why are drugs classified in the

A Look at Drug Abuse. Drugs are classified according to a number of different criteria, depending on the group doing the classifying and the reason for classification. For instance, from a therapeutic standpoint, a drug might be classified by the way it is used to treat illness. Other classification systems might classify drugs by active ingredients or chemical composition.

The Federal Food, Drug, and Cosmetic Act Early on, the government developed a very basic classification system for medicines and offered a general classification system for drugs sold commercially for medicinal purposes.

The Act has been amended several times to allow 1 why are drugs classified in the considerations that are used to investigate the efficacy of drugs or to incorporate new types of issues or information, such as preparations for bioterrorism and for other regulations regarding new developments in the manufacturing of drugs.

The FFDCA is concerned with medicinal drugs or drugs that are designed to treat, prevent, and cure, or that are used in the diagnoses of illnesses or diseases in people or animals. Medicinal drugs are classified into two major categories: Prescription drugs that can only be dispensed with a written prescription from a qualified healthcare professional, such as a physician, dentist, etc. Chemical compounds are drugs that are manufactured by combining specific chemicals in fixed proportions.

These are the drugs that most of the big pharmaceutical companies market. They are often further broken down into: Brand-name drugs are patented and can only be manufactured and distributed by the company that holds the patent, such as Tylenol. Generic drugs are basically the same composition but manufactured by different companies under different names; often generic drugs are less expensive than the brand-name versions, such as acetaminophen, which is generic for Tylenol.

Biologic drugs are composed of a wide range of different therapeutic products, such as vaccines, gene therapy materials, recumbent therapeutic proteins, and so forth. Unlike chemical drugs, biologics are manufactured in some type of a living organism or living system, such as a plant, animal, or even in a microorganism like a bacterium.

Drug Classes

These products require very strict regulations as they are highly sensitive to environmental changes, and even the slightest alteration in the conditions under which they are manufactured can affect their composition. Under this category, there are: Patented biologics can be manufactured and marketed only by the company holding the patent. Biosimilars are simply generic versions of biologics. These are rare because it is difficult for a company to establish that a biosimilar drug is equivalent to the original biologic in terms of its effectiveness and composition.

Biologic drugs are typically marketed as prescription drugs and are most often specialty drugs that are designed to have very specific uses. Ready to leave addiction behind?

When one reads a drug guide or textbook on drugsthese materials will often use these types of grouping criteria to classify drugs into specific categories.

When drugs are classified by their mechanism of action or therapeutic effects, certain drugs may be classified in more than one group. This results in a large number of potential classes of drugs. For instance, antidepressant drugs are drugs that are primarily used for the treatment of clinical depression, although they have other uses as well.

Antidepressant drugs are also classified according to their mechanism of action. Selective serotonin reuptake inhibitors, such as Prozac or Paxil, are primarily antidepressant drugs that act on the neurotransmitter serotonin, whereas tricyclic antidepressants, such as Elavil, act on three different neurotransmitters dopamine, serotonin, and norepinephrine.

The Federal Food, Drug, and Cosmetic Act

In addition, certain selective serotonin reuptake inhibitors are used in the treatment of anxiety disorders and even personality disorders, and may be classified as drugs designed to treat those conditions as well. Systems that are used for classifying drugs according to their chemical composition or mechanism of action are not limited to source guides or textbooks.

Several organizations classify drugs according to these methods or methods similar to them.

  1. These drugs produce marked euphoria and mood changes in people who use them. Drugs such as amphetamine, cocaine, fentanyl, hydromorphone oxycodone, and hydrocodone are included in Schedule II.
  2. Drugs that accelerate the activity of the central nervous system.
  3. The situation has resulted in some interesting speculation; in some states, a person may legally possess marijuana according to local laws, but be in violation of federal statutes. The central nervous system CNS consists of the brain and spinal cord, and it functions as the communication network for the body.
  4. For instance, from a therapeutic standpoint, a drug might be classified by the way it is used to treat illness.
  5. Hallucinogenic drugs include psilocybin found in magic mushrooms , lysergic acid diethylamide LSD , peyote , and dimethyltryptamine DMT.

For example, the National Drug File — Reference Terminology is a system of classification used by the United States Department of Veterans Affairs that classifies drugs based on four categories: Many drug manuals follow this particular classification system without regard to the potential for abuse of or addiction to the drug. The International Drug Evaluation and Classification Programan organization of law enforcement professionals, classifies drugs according to seven categories that are used to identify and clarify the types of drugs a particular suspect may have been taking.

Drug class

The categories of drugs are listed by their major behavioral effects to allow training for law enforcement professionals that enables them to quickly determine what type of drugs a person may have been taking based on behavioral observations of the person.

These seven major categories include: Central nervous system depressants: The central nervous system CNS consists of the brain and spinal cord, and it functions as the communication network for the body.

These drugs do not necessarily cause one to become depressed although taken in sufficient doses, they might have that effect on some people ; however, they depress or dampen the communication channels between neurons and nerves. This results in reduced heart rate, reduction in breathing, lower blood pressure, etc. Drugs in this category include alcohol, benzodiazepines anti-anxiety drugs barbiturates minor tranquilizersmany antidepressant medications although some classification systems give antidepressant medications their own categorymany drugs used in the treatment of psychosis although some classifications placed drugs used to treat psychosis in their own category, calling them antipsychotic drugsand others.

In larger doses, they may result in extreme hyperactivity, cause hallucinations, and lead to delusional or even psychotic behavior. Drugs in this category include amphetamines, cocaine crackcaffeine, methamphetamine, and many diet aids.

Introduction to Drug Utilization Research: Chapter 5: Drug classification systems

Hallucinogens are drugs that are often used as sleep aids or hypnotic enhancers. These drugs affect the CNS, alter perception of reality, and may have a sedating effect; however, they can also have a stimulating effect. Many of these drugs were originally used as sleep aids or by psychiatrists as aids for therapy. These drugs are used to inhibit the perception of pain.

What is the drug classification system?

They also distort perception, especially vision and hearing, and produce a feeling of being detached dissociated from the environment, hence their classification. Ketamine special KPCP, and similar drugs are examples. Narcotic analgesics are medications that are primarily used in the treatment of pain and derived from opium or from the poppy plant or synthetic chemicals similar to opium. These drugs produce marked euphoria and mood changes in people who use them. This category includes a wide range of breathable substances that are typically not sold as medications or drugs but marketed for other purposes.

This category also includes anesthetics that are administered in the form of breathable gases.

How Are Drugs Classified in America?

Examples include rubber cement, gasoline, paint thinner, hairspray, paint, etc. This includes all products that contain the active ingredient delta-9 tetrahydrocannabinol THC. This category includes marijuana, hashish, and synthetic drugs such as dronabinol. Many pharmaceutical texts add to the above classes by including specific categories for antidepressant medications, antipsychotic medications, antihistamines, and so forth.

This is 1 why are drugs classified in the case in many textbooks and on various drug information websites. Schedule I Substances Drugs in this classification are considered: To have a high potential to be abused To have no accepted medical treatment usage To lack an accepted safe protocol for use The drugs in this schedule are illegal to own, manufacture, or distribute except under conditions specified by the DEA this also includes synthetic versions of these substances.

Drugs in listed in Schedule I include: Certain opioid derivatives, such as heroin Certain hallucinogenic drugs, such as cannabis derivatives e. The situation has resulted in some interesting speculation; in some states, a person may legally possess marijuana according to local laws, but be in violation of federal statutes.

Schedule II Substances These substances are considered to: Have a high potential for abuse Have accepted medical use for treatment but typically only under certain conditions Result in severe physical dependence or psychological dependence if abused Except under extreme conditions, no drug appearing on Schedule II may be dispensed without a prescription, and some may not be dispensed to the general public at all e.

A few drugs under this designation include: Cocaine, which is still used in some cases as a topical anesthetic Amphetamines, including Adderall, Dexedrine, Ritalin, Concerta, and methamphetamine Certain narcotic drugs, including morphine, opium, codeine, fentanyl, methadone, oxycodone, and hydrocodone e.
