PH-Neutral Oxygen Absorbers for Pharmaceutical Stability: How Medshield Prevents Drug Polymerization

In pharmaceutical packaging, the stability of active ingredients is not just about oxygen control—it's also deeply tied to pH balance. Many drug formulations are sensitive to even minor shifts in acidity, especially when stored in sealed environments where moisture and chemical interactions are unavoidable.

Traditional oxygen absorbers often release acidic byproducts during oxidation, creating a localized acidic environment within the packaging. This can disrupt the pH equilibrium of the drug, accelerating polymerization reactions—particularly in protein-based therapeutics, biologics, and certain injectable solutions. The result? Premature degradation, reduced shelf life, and potential efficacy loss.

At Medshield, we’ve addressed this challenge through proprietary technology that ensures our oxygen absorbers remainpH-neutral or slightly alkalineduring the entire absorption process. By designing materials that activate under low-humidity conditions and maintain stable pH levels, we prevent the cascade of acid-induced polymerization that compromises drug integrity.This innovation is particularly critical for:

• Monoclonal antibodies(e.g., anti-inflammatory biologics)

• Peptide-based drugs(e.g., insulin analogs)

• Highly concentrated IV solutions(e.g., fat emulsions, amino acid mixtures)

• Lyophilized productswhere reconstitution pH is tightly controlled

OurMedshield Liquid Application seriesis engineered to absorb oxygen without introducing pH destabilization, making it ideal for use in sensitive formulations where regulatory compliance and long-term stability are non-negotiable.

Unlike generic oxygen absorbers that may compromise product quality through unintended chemical interactions, Medshield’s solution supports bothoxygen reductionandpH stability, ensuring your pharmaceuticals remain effective from manufacturing to patient use.
