Drug Classification
Drug sorting is a way to organize and categorize drugs based on various criteria. This includes their chemical composition, how they work in the body (mechanism of action), the condition or disease they treat (therapeutic indication), and whether they require a prescription or can be purchased over the counter. Let's explore these categories in detail.
1. Chemical Classification
The chemical classification of drugs is based on the chemical structure of the active ingredients. For example, antibiotics can be classified as penicillins, cephalosporins, quinolones, among others, based on their chemical structure. This classification is useful for healthcare professionals, as drugs with similar chemical structures tend to have similar properties and side effects.
2. Classification by Mechanism of Action
Classification by mechanism of action refers to how a drug works in the body to produce its effect. For example, blood pressure medications can be classified as diuretics, beta blockers, calcium channel blockers, etc., based on how they work to lower blood pressure.
3. Therapeutic Classification
The therapeutic classification of drugs is based on the condition or disease they are used to treat. For example, drugs can be classified as antidiabetics, antipsychotics, analgesics, and so on, based on the condition they treat. This classification is useful for patients and healthcare professionals as it allows for easy identification of the appropriate drug for a given condition.
4. Classification by Prescription or Over-the-counter
Drugs are also classified based on whether they require a prescription or can be purchased without a prescription. Prescription drugs are those that can only be obtained with a doctor's prescription because of their potential for serious side effects or misuse. On the other hand, over-the-counter medications are those that can be purchased without a prescription, as they are considered safe to use without medical supervision.
