Prescription drugs are divided into three categories: controlled substances, non-controlled substances, and over-the-counter (OTC) drugs. Controlled substances, such as opioids and stimulants, have high potential for abuse and are regulated by the Drug Enforcement Administration.
Non-controlled substances are medications that do not cause physical dependence or alteration of one’s mental state, but are still regulated by the FDA and require a prescription from a medical doctor.
Examples include antibiotics, antidiabetic drugs, anti-inflammatory medications, and antidepressants. OTC drugs are medications that can be purchased without a prescription, such as ibuprofen, acetaminophen, and certain cold and allergy medicines.
However, some OTC medications should still be taken with caution as they can also have serious side effects with incorrect or overuse.

What are the three 3 classification of drugs?
The three classifications of drugs are prescribed drugs, over-the-counter drugs, and illicit drugs. Prescribed drugs are those that are given to a patient by their healthcare provider and are typically used to treat a specific medical condition.
Over-the-counter drugs are medications that are available without a prescription. These drugs usually treat minor illnesses and conditions such as coughs, colds, allergies, etc. Illicit drugs are substances that are not approved for use by the government and can be harmful to the user.
These typically include drugs such as cocaine, methamphetamine, and heroin.
What are the major medication categories?
The major medication categories are as follows:
1. Antibiotics: These medications treat infections caused by bacteria and other microorganisms. Examples include penicillin, tetracycline, and ciprofloxacin.
2. Antivirals: These are medications used to treat infections caused by viruses. Examples include acyclovir, famciclovir, and valacyclovir.
3. Antifungals: These medications are used to treat fungal infections such as athletes foot and ringworm. Examples include fluconazole, itraconazole, and terbinafine.
4. Antiparasitics: These medications are used to treat and prevent infections caused by parasites. Examples include mebendazole and ivermectin.
5. Antiseptics: These medications are used to reduce the growth of harmful microorganisms on the skin or other surfaces. Examples include chlorhexidine and povidone-iodine.
6. Pain relievers: These medications are used to relieve pain, reduce fever, and reduce inflammation. Examples include paracetamol, aspirin, and ibuprofen.
7. Antihistamines: These medications are used to treat allergies and other conditions related to the body’s immune system. Examples include loratadine, cetirizine, and fexofenadine.
8. Vitamins and Minerals: These medications are used to replenish essential nutrients in the body. Examples include multivitamin tablets, calcium supplements, and iron supplements.
9. Hormones: These medications are used to treat conditions, such as hypothyroidism, caused by an imbalance of hormones. Examples include thyroxine and corticosteroids.
10. Antidepressants: These medications are used to treat depression and other mood disorders. Examples include selective serotonin reuptake inhibitors (SSRI’s) and tricyclic antidepressants.
How are medications grouped?
Medications are generally grouped into categories by therapeutic use, route of administration, chemical structure, or mechanism of action. Therapeutic use classifications group drugs based on the condition or symptoms they are intended to treat, such as antibiotics, analgesics, and cardiovascular medications.
Drugs that are administered in the same way will typically fall under the same route of administration classification, for example oral, topical, or nasal. Chemical structure classifications group medications based on their chemical structure and can include categories such as steroids, anticonvulsants, and analgesics.
Lastly, mechanism of action classifications group medications based on the biological processes they affect, such as receptor agonists, enzyme inhibitors, and hormone blockers.
By grouping medications in this way, it makes it easier for healthcare providers to quickly determine which drugs may be suitable for a particular patient. Additionally, it helps them to recognize potential drug interactions and identify when a patient may benefit from combining two or more medication therapies.
How many categories are there in medicine?
There are a wide variety of specialties within the field of medicine, including both primary care and specialty care. Primary care physicians provide basic healthcare needs such as preventive care and general treatment of acute and chronic illnesses, while specialty care physicians focus on specific areas such as cardiovascular disease, endocrinology, and infectious diseases.
Within each of these broad categories are numerous subspecialties. For example, within the field of cardiology there are specialties such as interventional cardiology, electrophysiology, and pediatric cardiology.
In addition, many other medical disciplines exist outside of the traditional primary and specialty care areas. These include allied health professions such as nurses, dentists, pharmacists, physical therapists, and other health care professionals with specialized knowledge and skills.
Altogether, there are more than 120 distinct medical specialties and subspecialties across the world. With the growth of technology, the number of specialized areas within medicine is constantly changing and expanding.
How many medication classifications are there?
There are 8 primary medication classifications, which are organized according to the main body systems they affect. These main classifications are: 1) Central Nervous System medications; 2) Cardiovascular medications; 3) Hormones; 4) Immunomodulators; 5) Anti-infectives; 6) Gastrointestinal medications; 7) Respiratory medications; and 8) Pain medications.
Each of these main classifications are further organized into more specific sub-categories, further breaking down into categories such as antibiotics, antacids, diuretics, anticoagulants, and more. Within these sub-categories, there are thousands of different medications and treatments that are available, making the number of possible medication classifications virtually endless.
What do the three classes of drugs stand for?
The three classes of drugs refer to the broad categories of legal and illegal substances which are regulated and controlled by the government. The first class of drugs, controlled substances, includes drugs like marijuana and cocaine that are illegal, addictive, and highly dangerous.
The second class, prescription drugs, includes drugs that can only be obtained with a prescription from a healthcare provider. They are considered safe for use when taken as prescribed, but when taken without a healthcare provider’s knowledge, can lead to dependence and addiction.
The last class, over-the-counter drugs, consists of beverages (alcohol) and medications that can be bought without a prescription. Examples are analgesics, sleep aids, antihistamines, and dietary supplements.
These drugs are generally safe when used as directed, but some can have dangerous side effects if used improperly.
What are 3 critical components that should be included on every prescription label?
1. Patient Name & Address: This should include the patient’s full legal name and address in order to identify the patient and ensure accurate record-keeping.
2. Drug Name & Strength: This should include the name of the drug prescribed, along with the dosage and strength to provide clear instructions for the patient.
3. Directions for Use: This should include detailed instructions on how to take the prescription, including the dosage and frequency. This is particularly important for more complex medications, such as those commonly used to treat chronic conditions.
Other important instructions may include proper storage and disposal of the drug, how to monitor for adverse effects and when/how to seek medical attention.
