Water-resistant materials are used in pharmaceutical packaging which must be resistant to water, and this is because it is a critical matter that affects the efficacy and safety of drugs through several mechanisms:
Waterproofing materials create blockades that thwart entry of moisture into the packaging. Moisture may trigger chemical disintegration in those drugs, especially those sensitive to dampness, however this material maintains dry surroundings for the pharmaceutical product so as no to affect its chemical stability.
Pharmaceuticals can be affected physically with moisture like dissolution rate, hardness and disintegration time of tablets or capsules.
Waterproof materials contribute towards preventing microbial contamination. Microorganisms flourish in damp conditions and their presence can ruin drug sterility. These materials prevent microbial growth by building a water and moisture barrier thus keeping the product safe.
Moisture proof packaging not only saves from wetting but also prevents various external contaminants such as dust particles among other pollutants from finding their way into the drug. This is necessary for maintaining the quality and purity of pharmaceutical products thereby avoiding contamination that can tamper with their safety and usefulness.
Their ability to resist water and environmental factors contributes towards long life span of pharmaceuticals. Water resistant packagings protect drugs from rapid deterioration via effects of moisture or other external factors thus remaining potent and effective during their intended storage period.
Some medicines are very responsive to any variation in moisture content which interferes with bioavailability. Water-resistant packages help maintain bioavailability of drugs through preventing changes in solubility or dissolutions rates due to wetness.
Stability requirements for drugs such as the way they should be stored to ensure their safety and effectiveness have been set by pharmaceutical regulatory authorities. At the same time, water-resistant materials help meet these demands for drugs since they provide a protective barrier that sustains the drug’s stability over time.
Water-proof materials are essential because they prevent interference of external factors on a drug as well as leaching harmful content out of or into the drug from its container.
