nanoemulsions

Overview

Nanoemulsions are advanced colloidal systems where minuscule droplets of one liquid (typically oil) are dispersed within another (usually water). These droplets are incredibly small, usually between 20 to 200 nanometers, which is about 500 times thinner than a human hair. Their small size contributes to their unique characteristics such as a larger surface area for drug interaction, leading to enhanced drug delivery efficiency.

Significance in Pharmaceutical Development:

  • NanoEmulsions are important in the development of modern pharmaceuticals, particularly for improving the solubility and bioavailability of drugs.
  • They are instrumental in overcoming common challenges associated with oral dosage forms, such as poor water solubility and inconsistent drug release profiles.
  • The technology enables the formulation of more effective and patient-friendly pharmaceuticals.

Advantages of NanoEmulsions for Oral Dosage Forms:

  • Superior Bioavailability: The nano-sized droplets facilitate a more efficient absorption process in the gastrointestinal tract, leading to higher bioavailability.
  • Stability and Longevity: NanoEmulsions protect the encapsulated drug from degradation, ensuring prolonged stability and effectiveness.
  • Adaptable Formulation: They can be engineered to carry a wide variety of drugs, making them a versatile option for many therapeutic categories.
  • Enhanced Patient Experience: Due to their small size and the potential for flavor masking, NanoEmulsions can significantly improve patient compliance.

Technology

High-Energy Preparation Techniques:

  • Ultrasonication: Renejix uses ultrasonic energy to produce cavitation in the liquid medium, leading to the formation of nano-sized droplets.

Low-Energy Preparation Techniques:

  • Phase Inversion Temperature (PIT): This technique induces spontaneous formation of nano-sized droplets as the system undergoes temperature changes.
  • Spontaneous Emulsification: This method allows for the natural diffusion of solvents, resulting in the formation of nano-sized oil droplets.

Manufacturing Process

  • Phase Preparation: Renejix scientists begins with precise preparation of the oil and aqueous phases, ensuring the compatibility and quality of the drug and excipients.
  • Emulsifiers Selection: The selection of surfactants and co-surfactants is crucial for the stability of the Nanoemulsion, and our scientists choose these based on the drug’s properties and the desired emulsion characteristics.
  • Primary Emulsion: High-shear mixing equipment combines the oil and aqueous phases to form a primary emulsion, setting the stage for nano-sizing.
  • Nano-Sizing: Renejix employs advanced high-energy methods like ultrasonication or high-pressure homogenization to reduce the droplet size to the nanometer range, ensuring uniformity and stability.
  • Quality Control: In-process controls are in place to monitor the emulsion’s characteristics, with adjustments made as needed to meet stringent specifications.
  • Stabilization: Post-size reduction, the Nanoemulsion is stabilized using cutting-edge techniques to ensure long-term stability and efficacy.
