An efficient protocol for assessing both the chemical and physical stability of cocrystalline forms of active pharmaceutical ingredients (APIs) is proposed. In this protocol, the cocrystalline material is used to prepare two standard formulations, mi

A model is presented for determining the time when an active pharmaceutical ingredient in tablets/powders will remain within its specification limits during an in-use period; that is, when a heat-induction sealed bottle is opened for fixed time perio

Three competing mathematical fitting models (a point-by-point estimation method, a linear fit method, and an isoconversion method) of chemical stability (related substance growth) when using high temperature data to predict room temperature shelf-lif

A proposed generalized relationship for the impact of excipients on the solid-state chemical stability of drug products is presented and shown to be consistent across multiple degradation products with two example drugs. In this model, when the numbe

The chemical reaction rate for solid-state product formation in a pharmaceutical case study was monitored by equilibration with either a 75%, 21.5%, 75% relative humidity (RH) cycle ("high-low-high", HLH) or a 21.5%, 75%, 21.5% RH cycle ("low-high-lo
