Abstract

Insights

Chemoprevention clinical trials in familial adenomatous polyposis (FAP) have established a basis for using drugs like sulindac and celecoxib. These trials also provide a foundation for studying chemoprevention in non-familial adenomas.

Area of Science:

  • Gastroenterology and Oncology
  • Clinical Pharmacology

Background:

  • Primary prevention, or chemoprevention, of adenomas is a key consideration in managing colorectal cancer risk.
  • Familial adenomatous polyposis (FAP) serves as a crucial model for studying chemoprevention strategies.
  • Numerous agents and combinations have demonstrated potential in clinical trials.

Purpose of the Study:

  • To review the current state of chemoprevention in familial adenomatous polyposis (FAP) from a clinical perspective.
  • To highlight the role of FAP chemoprevention trials in guiding clinical drug use.
  • To establish how FAP trials can inform future research in non-familial adenomas.

Main Methods:

  • Focus on randomized clinical chemoprevention trials.
  • Systematic literature search of PubMed from 1980 to present.

Main Results:

  • Established the clinical utility of sulindac and celecoxib as adjuncts in FAP management.
  • Demonstrated the value of FAP trials in providing a foundation for broader chemoprevention research.
  • Highlighted the role of short-term drug administration (3-12 months) in assessing adenoma regression.

Conclusions:

  • FAP trials are essential for evaluating new chemopreventive agents.
  • Adenoma regression in retained rectal segments is a key endpoint.
  • Findings from FAP studies can be extrapolated to non-familial adenoma chemoprevention.

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

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.

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.

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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 Disease...
