Investigating the physical stability of repackaged medicines stored into commercially available multicompartment compliance aids (MCAs)

Abstract

BackgroundCompliance aids are devices which have been developed and are currently used to assist individuals in their medicines management. The use of compliance aids involves the transfer of medicines from the manufacturers' original packaging and repackaged into an multicompartment compliance aid (MCA). MCAs do not guarantee the same level of protection compared to manufacturer's original packaging.ObjectiveThe aim of this study was to investigate the stability profile of atenolol, aspirin and lansoprazole dosage forms repackaged together in two different commercially available MCAs.MethodsIn a laboratory in the United Kingdom, the physical stability of the formulations repackaged into two commercially available brands of MCAs was evaluated. After 8 weeks of storage (under controlled ambient conditions), changes in the disintegration (tablets only) and dissolution properties (all formulations) were examined in accordance with British Pharmacopoeia (BP) specifications.Key findingsFindings from this study confirm that changes in solid‐dosage form quality are observed when repackaged into MCAs compared to manufacturers packaging resulting in differences in in‐vitro dissolution performance. However, even with these changes, overall product performance was acceptable and within BP specifications.ConclusionThere is a need for greater collaboration in this area between manufacturers, hospital and community pharmacists, academics and policymakers to increase the data available on the physical stability and in turn performance of medicines repackaged into MCAs.

“…This custom packaging saves volume and mass, but could affect pharmaceutical stability by altering exposure to heat, light, humidity, and gases; the packaging itself could interact with the medications as well [32] [38][39] [64]. The accelerated degradation of medications in previous studies has been attributed to repackaging [32], although the effects of repackaging on pharmaceutical stability are not fully understood [65]. The protective, compatible, safety, and performance capabilities of container closure systems should be decided according to the routes of administration and dosage forms [64].…”

“…Multidrug formulations could reduce drug dosage and potential side effects whilst simplifying administration regimens (Aljuffali et al, 2016;Okuda & Kidoaki, 2012;Das et al, 2010). Such products can often be prepared as physical mixtures of the active pharmaceutical ingredients (APIs) in the desired dose, although the resulting multiphase system might be difficult to process and to store over time (Raimi-Abraham et al, 2017). Alternatively, a stable crystalline phase can be obtained by combining multiple active ingredients in a cocrystal (Kavanagh et al, 2019a;Bordignon et al, 2017).…”
