Parenteral Drug Delivery Systems: Injectables, Implants, and Infusion Devices01:28

Parenteral Drug Delivery Systems: Injectables, Implants, and Infusion Devices

Parenteral drug delivery systems play a crucial role in modern therapeutics by enabling the direct administration of drugs into the systemic circulation, bypassing the gastrointestinal tract. These systems are particularly valuable for poorly absorbed oral medications that are unstable in the digestive environment or require rapid onset or sustained therapeutic levels. Delivery is achieved through intravenous, intramuscular, or subcutaneous routes, each selected based on the drug's properties...
Bioavailability Enhancement: Drug Permeability Enhancement01:27

Bioavailability Enhancement: Drug Permeability Enhancement

After oral administration, poor permeability often limits the rate at which drugs are absorbed through the intestinal epithelium. Enhancing drug permeability is crucial for effective therapy, and several strategies have been developed to overcome this challenge.One effective strategy involves the use of lipid-based formulations. These formulations enhance dissolution and solubility, targeting physiological mechanisms to increase drug absorption. This includes stimulating bile salt secretion,...

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...

Summary

Lipid emulsions in parenteral nutrition can impact immune function. Newer formulations using fish oil, olive oil, or coconut oil may offer improved immune modulation compared to traditional soybean oil emulsions.

Area of Science:

  • Clinical Nutrition
  • Immunology
  • Biochemistry

Background:

  • Total parenteral nutrition (TPN) is crucial for severe intestinal failure.
  • Lipid emulsions are primary calorie sources in TPN but linked to adverse immune effects.
  • Soybean oil emulsions, high in n-6 PUFAs, may have proinflammatory potential.

Purpose of the Study:

  • To review the immunologic characteristics of various lipid emulsions used in TPN.
  • To compare the immune effects of different lipid formulations.
  • To synthesize current knowledge on lipid emulsion impact on host defenses and inflammation.

Main Methods:

  • Literature review of studies on lipid emulsions in parenteral nutrition.
  • Analysis of fatty acid composition and immunologic data.
  • Synthesis of research on soybean oil, coconut oil, olive oil, and fish oil emulsions.

Main Results:

  • Soybean oil emulsions' high n-6 PUFA content is a concern for inflammation.
  • Alternative oils (coconut, olive, fish) are explored to modulate immune responses.
  • Fish oil emulsions show promise in beneficially altering immune-mediated conditions.

Conclusions:

  • Different lipid emulsions possess distinct immunologic characteristics.
  • Alternative lipid formulations may offer advantages over traditional soybean oil emulsions.
  • Further research and availability of novel emulsions are needed to optimize TPN support.
