    Therapeutic drug monitoring is a strategy utilized to optimize biological therapy. It consists in the drug level measurement before the next dose is due, when the drug concentration reaches the trough level, and includes the detection of potential antidrug antibodies. The monitoring makes it possible to adjust the therapy accordingly - to intensify or change the biologics applied to secure safe and highly effective therapeutics. Therapeutic optimization is based on the nature of therapy failure, which can be caused by pharmacokinetic or pharmacodynamic factors. Pharmacokinetic monitoring can be currently classified as reactive, measuring the drug level and antidrug antibodies during therapy failure, or adverse reactions to the drug applied, and proactive, monitoring patients in clinical remission to retain remission and prevents development of a secondary failure.

    Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF01:24

    Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

    Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

    Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

    Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

    Inflammatory Bowel Disease IV: Pharmacological Management

    Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

    Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

    Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

    A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

    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...
