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,...

Site-Targeted Drug Delivery Systems: Polymeric Carriers

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells. Monoclonal...
Ophthalmic Drug Delivery Systems01:23

Ophthalmic Drug Delivery Systems

Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

Area of Science:

  • Pharmaceutical Sciences
  • Biotechnology
  • Ophthalmology

Background:

  • Biocompatible lipid nanocarriers enhance solubility of poorly soluble drugs for ophthalmic diseases.
  • Micro-/nanoemulsions, solid lipid nanoparticles (SLN), and nanostructured lipid carriers (NLC) improve drug stability and ocular bioavailability.
  • Current trial-and-error methods hinder fine-tuning nanoparticle populations for ocular delivery, impacting regulatory approval.

Purpose of the Study:

  • To review the application of design of experiments (DoE) in optimizing lipid-based nanocarriers for ophthalmic administration.
  • To highlight strategies for predictable quality and specifications in nanocarrier production.
  • To introduce DoE as a valuable tool for nanomedicine research and industrial development.

Main Methods:

  • Literature review focusing on the implementation of design of experiments (DoE) for nanocarrier formulation.
  • Discussion of quality-by-design (QbD) principles in contrast to quality-by-testing (QbT).
  • Explanation of multivariate approaches using statistical DoE for process optimization.

Main Results:

  • DoE enables mathematical modeling to predict nanoparticle characteristics based on process variables.
  • This approach optimizes drug delivery platforms, reducing research costs and time.
  • DoE facilitates a deeper understanding of the nanocarrier production process.

Conclusions:

  • Design of experiments (DoE) offers a systematic approach to overcome challenges in ocular nanomedicine development.
  • Implementing DoE leads to predictable quality and efficient optimization of lipid-based nanocarriers.
  • This methodology is crucial for advancing nanotherapeutic development and regulatory success in ophthalmology.
