Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism01:21

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism

374
Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...

Factors Affecting Dissolution: Drug Permeability, Stability and Stereochemistry

248
Orally administered drugs primarily enter the systemic circulation via passive diffusion through the intestinal membranes. The drug's absorption is influenced by drug stability in the gastrointestinal GI tract, membrane permeability, the surface area available for absorption, luminal drug concentration, and residence time in the lumen. Drug permeability can be enhanced by adjusting the lipophilicity, polarity, or molecular size of the drug, promoting its passive transport across intestinal...

Antibody Structure and Classes01:25

Antibody Structure and Classes

3.2K
Antibodies, also known as immunoglobulins, are produced by B cells in response to foreign substances, such as bacteria and viruses. These proteins are critical for recognizing and neutralizing these substances, protecting the body from potential harm.
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibody Actions

1.3K
Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.
Neutralization
Antibodies can bind to pathogens, preventing them from infecting host cells. This process...

Area of Science:

  • Biopharmaceutical development
  • Protein chemistry
  • Drug formulation

Background:

  • Combined antibody therapeutics offer benefits for cancer and infectious diseases.
  • Fixed-dose coformulations are increasingly preferred for antibody drug delivery.
  • Protein-protein interactions in coformulations can impact antibody stability and degradation.

Purpose of the Study:

  • To investigate the stability profiles of antibodies within coformulations.
  • To understand the impact of antibody-antibody interactions on individual component stability.
  • To examine the overall stability convergence in antibody coformulations.

Main Methods:

  • Analysis of two specific antibody-antibody coformulations.
  • Assessment of individual antibody stability in isolation versus in mixture.
  • Evaluation of changes in degradation profiles within the coformulation.

Main Results:

  • The more stable antibody component enhanced the stability of the less stable component.
  • Conversely, the less stable antibody component decreased the stability of the more stable component.
  • Coformulations demonstrated an overall convergence of stability between antibody components.

Conclusions:

  • Antibody coformulations exhibit a dynamic interplay affecting individual component stability.
  • Stability convergence is a key characteristic of antibody-antibody coformulations.
  • Understanding these interactions is crucial for developing stable and effective fixed-dose antibody therapies.
