    Antifungal Agents

    Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
    Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents01:24

    Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents

    In the intricate landscape of the gastric lumen, excessive acid secretion disrupts the natural defense mechanisms, weakening the mucus-bicarbonate barrier. This vulnerability allows pepsin to infiltrate epithelial cells, digesting mucosal proteins and triggering erosion, leading to ulcer formation.
    In this scenario, mucosal protective agents like sucralfate play an essential role. Sucralfate, a complex of sulfated sucrose and aluminum hydroxide, demonstrates its usefulness in acidic conditions,...

    Drugs for Treatment of Ulcerative Colitis in IBD

    Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide generation. 
    Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors01:13

    Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors

    Peptic ulcers, often induced by H. pylori infections or NSAID usage, arise from disruptions in the delicate balance of gastric acid production. Peptic ulcers stem from heightened gastric acid levels due to H. pylori infections or NSAID use. The protective mucus layer diminishes in the presence of these factors, allowing gastric acid to erode the stomach lining and form ulcers.
    Gastric acid, a potent cocktail of hydrogen and chloride ions, is produced in specialized parietal cells within the...

    Drugs for Peptic Ulcer Disease: Prostaglandin Analogs as Mucosal Protective Agents

    The gastric mucosa produces prostaglandins E2 (PGE2) and prostacyclin (PGI2), crucial in maintaining gastric health. They exert cytoprotective effects, including increasing bicarbonate secretion, releasing protective mucin, reducing gastric acid output, and preventing harmful vasoconstriction. These effects are mediated through various receptors, such as EP1, EP2, EP3, and EP4.
    Non-steroidal anti-inflammatory drugs (NSAIDs) can induce peptic ulcers by inhibiting cyclooxygenase, decreasing...

    Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy

    Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...
