Here are some frequently asked questions about Lipid-Based Drug Delivery

What is a lipid-based drug delivery system?
  1. A lipid-based drug delivery system is a method of delivering drugs that uses lipids as carriers. These systems can improve the solubility and absorption of drugs, particularly those that are poorly soluble in water. They can also protect drugs from degradation in the gastrointestinal tract.
How does Renejix enhance the bioavailability of poorly water-soluble drugs using lipid-based drug delivery systems?
  1. Renejix uses advanced formulation techniques to create lipid-based drug delivery systems that can enhance the bioavailability of poorly water-soluble drugs. These techniques can include the use of liposomes, nanoemulsions, or solid lipid nanoparticles. By encapsulating the drug in a lipid carrier, it can be more easily absorbed in the gastrointestinal tract.
What types of lipid excipients are commonly used in Renejix’s lipid-based drug delivery systems?
  1. Renejix uses a variety of lipid excipients in their drug delivery systems, including natural and synthetic lipids. These can include phospholipids, triglycerides, fatty acids, and cholesterol. The choice of lipid excipient depends on the properties of the drug and the desired release profile.
What are the key considerations when Renejix formulates a lipid-based oral dosage?
  1. When formulating a lipid-based oral dosage, Renejix considers factors such as the physicochemical properties of the drug, the desired release profile, the stability of the formulation, and the manufacturability of the dosage form.
