Pharmacology of Co-trimoxazole

by
Co-trimoxazole

Introduction Co-trimoxazole—a combination of sulfamethoxazole and trimethoprim—has been a cornerstone antibacterial agent for decades. The synergy between these two drugs proves highly effective against a broad range of Gram-positive and Gram-negative microorganisms. First introduced in the 1960s, co-trimoxazole quickly rose to prominence, offering a potent yet pragmatic solution for infections spanning the respiratory, urinary, and gastrointestinal tracts, among others (Goodman & Gilman, 2018). As antibiotic resistance … Read more

Pharmacology of Aminoglycoside antibiotics

by
Aminoglycosides

INTRODUCTION Aminoglycoside antibiotics are a class of potent, broad-spectrum bactericidal agents that have played a critical role in the management of serious bacterial infections for decades. First derived from microbial sources in the mid-20th century, these compounds quickly became indispensable, especially for treating infections caused by aerobic Gram-negative bacteria. Despite the rise of newer antimicrobial … Read more

Pharmacology of Fluoroquinolones

by
Fluoroquinolones

Fluoroquinolones are one of the most significant classes of broad-spectrum antimicrobial agents used in modern medicine. With their ability to target both Gram-positive and Gram-negative bacteria, these agents are frequently employed in various clinical scenarios, from community-acquired respiratory infections to complicated hospital-acquired pathogens. Developed from the original compound nalidixic acid in the 1960s, fluoroquinolones have evolved to exhibit increased potency, improved … Read more

Pharmacology of Macrolides

by
Macrolides

Macrolides are a group of antibiotics characterized by a macrocyclic lactone ring attached to various amino or neutral sugars. They are widely used in clinical medicine, particularly against respiratory pathogens and certain atypical organisms. Erythromycin was the first macrolide discovered (isolated from Streptomyces erythreus in the 1950s), followed by newer “second-generation” and “third-generation” agents such … Read more

Principles of Antimicrobial Chemotherapy

by
Antimicrobial Resistance

Antimicrobial chemotherapy has transformed modern medicine, providing effective treatments for a wide array of infectious diseases. Its rational application relies on core scientific and clinical principles to optimize use, minimize harm, and combat resistance. Introduction Antimicrobial agents target bacteria, fungi, viruses, and parasites. Their selection and use are guided by principles aiming at maximal efficacy, minimal harm, … Read more

Antimicrobial resistance

by
antimicrobial resistance

Antimicrobial resistance is a leading global health threat, characterized by the ability of microbes (bacteria, fungi, viruses, parasites) to withstand drugs formerly effective against them. The emergence and spread of AMR threatens the effectiveness of essential medical treatments, increases morbidity and mortality, and imposes substantial costs on healthcare systems and societies. What is Antimicrobial Resistance? … Read more

The history and evolution of antimicrobial agents

history of antimicrobial agents

The development of antimicrobial agents stands as one of the most significant achievements in medical history. From ancient remedies to the modern era of targeted chemotherapeutics, the journey of these life-saving drugs illustrates remarkable ingenuity, scientific progress, and ongoing challenges such as antimicrobial resistance. Early Observations and Ancient Remedies Humans used moulds, plant extracts, and … Read more

Physiology of the Thyroid Gland

by
Physiology of thyroid gland

Introduction The thyroid gland plays a pivotal role in human physiology, modulating metabolism, growth, and development through the production and secretion of thyroid hormones. These hormones, primarily triiodothyronine (T3) and thyroxine (T4), influence virtually every tissue in the body, from skeletal muscle to neural tissue. Understanding thyroid physiology is paramount for grasping how the body maintains metabolic equilibrium, how it responds … Read more
