Captopril, an angiotensin-converting enzyme inhibitor used to manage congestive heart failure in the paediatric population, has limited data on efficacy and safety. Its variety of liquid formulations dispensed by different pharmacies poses a challenge in optimizing captopril dosing in patients. Fourteen tertiary paediatric centre pharmacies across Canada were contacted to decipher the type of captopril formulation they dispense, their recipe and the stability of each formulation. Of the 14 centres surveyed, four dispensed solid tablets, two dispensed either solid tablets or liquid formulations, and eight dispensed extemporaneously prepared liquid formulations. There was also great variety in the solutions used to prepare the liquid formulations. The bioequivalence of these preparations has not been studied. As a result, physicians cannot be certain about the effective dose of captopril. Uniformity is recommended among paediatric pharmacies in Canada when preparing medications such as captopril. Proper testing of the stability and bioequivalence of medications is recommended.

Poly(DL-lactide-co-glycolide) (PLGA) and N-methyl-2-pyrrolidone (NMP)-based in situ forming implants are liquid formulations that solidify through phase separation following injection into the body. Drug is dissolved or suspended in the final formulation liquid prior to injection. Depending on the polymers used, the depots formed can deliver drug over different periods of time.

Turmeric (Curcuma longa L.) has gained significant attention for its medicinal properties, yet its therapeutic applications are often limited by low aqueous solubility and susceptibility to environmental factors. This study investigates the formulation of a curcumin-rich turmeric extract-β-cyclodextrin inclusion complex (TUE-β-CD) to enhance its bioactivity and stability.

Precision medicine in less-defined subtype diffuse large B-cell lymphoma (DLBCL) remains a challenge due to the heterogeneous nature of the disease. Programmed cell death (PCD) pathways are crucial in the advancement of lymphoma and serve as significant prognostic markers for individuals afflicted with lymphoid cancers. To identify robust prognostic biomarkers that can guide personalized management for less-defined subtype DLBCL patients, we integrated multi-omics data derived from 339 standard R-CHOP-treated patients diagnosed with less-defined subtype DLBCL from three independent cohorts.

Chronic diabetic wound poses a pressing global healthcare challenge, necessitating an approach to address issues such as pathogenic bacteria elimination, blood sugar regulation, and angiogenesis stimulation. Herein, we engineered a BiWO@CuO-GOx bio-heterojunction (BWCG bio-HJ) with exceptional cascade catalytic performance and impressive sonosensitivity to remodel the wound microenvironment and expedite the diabetic wound healing. Specifically, the Z-scheme junctions of BiWO@CuO significantly augmented carrier separation dynamics, leading to the highly efficient generation of reactive oxygen species (ROS) upon US irradiations.
