Which outcome occurs when a desiccant fails during pharmaceutical lyophilization?

💡 Explanation

Product collapse happens because the desiccant's failure to maintain dryness enables ice crystal reformation during sublimation from water reabsorption; the mechanism is glass transition. Therefore, the product collapses rather than sublimates completely or risks vacuum pump failure.
