A stable extemporaneous product is defined as one that retains at least 90% of the initial drug concentration throughout the sampling period. The study showed that allopurinol concentrations did not go below 93% of the label claim (initial drug concentration) at both temperatures studied. Viscosity and pH values also did not change significantly. This study demonstrates that allopurinol is physically and chemically stable in SuspendIt for 180 days in the refrigerator and at room temperature, thus providing a viable, compounded alternative for allopurinol in a liquid dosage form, with an extended beyond-use-date to meet patient needs.There is still an evident need for nonsterile compounded medications for pediatric and elderly patients in cases where patients require dose adjustments or have swallowing difficulties. Pharmacists generally have the choice between compounding capsules or oral liquids. In daily pharmacy practice, extemporaneous capsules are from time to time seen as a better alternative to oral liquid medication, although various published studies indicate that weight variation and/or uniformity of content can be significantly out of specification for compounded capsules. In contrast, analyses with the ready-to-use oral liquid vehicle SyrSpend SF in 104 different formulations with 89 unique active pharmaceutical ingredients showed results that all 6.414 samples analyzed were within specification. It can, therefore, be argued that SyrSpend SF could be a better way to assure content uniformity compared to manually compounded, small-batch extemporaneous capsules.In the formulation of parenteral dosage forms, pH is a critical factor and can be a complicated factor in compounding intravenous admixtures since the additives and the vehicle may have different pH values. This is especially important, as a significant number of parenteral medications require compounding involving dissolution of
