Drug Classes and Categories

1.8K
Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

131
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Local Anesthetics: Common Agents and Their Applications

364
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Drug Nomenclature01:17

Drug Nomenclature

1.5K
During the development of a new pharmaceutical, the manufacturer initially assigns a code name to the drug. Once approved, the drug receives a United States Adopted Name (USAN)—a generic, nonproprietary designation. Upon being listed in the United States Pharmacopeia, this nonproprietary name becomes the drug's official name. Additionally, the manufacturer assigns a proprietary name or trademark, which serves as the brand name under which the drug is marketed. It is worth noting that...

Cardiovascular Drugs: Classification based on Therapeutic Indications

1.8K
Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However,...

Dose-Response Relationship: Potency and Efficacy01:22

Dose-Response Relationship: Potency and Efficacy

4.0K
The potency of a drug is the measure of its ability to produce a biological response and can be compared by looking at the half-maximum effective concentration or EC50 values of different drugs. A lower EC50 value indicates higher potency of the drug. In the dose–response curve of two antihypertensive drugs, candesartan and irbesartan, a significant difference is observed in their EC50 values. A lower EC50 value for candesartan indicates that it is more potent than irbesartan, as it...

    Summary
    This summary is machine-generated.

    Topical corticosteroids (TCS) are widely used for skin conditions but lack a universal potency classification. This review proposes a unified system to reduce confusion in prescribing these potent medications.

    Area of Science:

    • Dermatology
    • Pharmacology

    Background:

    • Topical corticosteroids (TCS) are a cornerstone therapy for numerous dermatologic conditions.
    • Their efficacy and tolerability are well-established, but a lack of standardized potency classification hinders optimal use.

    Purpose of the Study:

    • To review and synthesize existing literature on topical corticosteroid potency and classification systems.
    • To propose a novel, universal classification system for TCS that enhances clarity and consistency.

    Main Methods:

    • Comprehensive literature search and analysis of existing TCS potency data.
    • Evaluation of current international classification frameworks for topical corticosteroids.

    Main Results:

    • Current TCS classification systems are fragmented and lack universal acceptance.
    • Significant variability exists in how TCS potency is categorized across different regions.

    Conclusions:

    • A unified, universally accepted classification system for topical corticosteroids is needed.
    • The proposed system aims to simplify clinical decision-making and improve patient outcomes by reducing confusion in TCS selection.
