Long-term physicochemical stability of acyclovir 5 mg/mL solution stored in polypropylene bags as a simulated hospital stock preparation.

Purpose: To investigate the long-term chemical and physical stability of 5-mg/mL acyclovir solution in polypropylene bags stored at 5°C ± 3°C for 2 months in order to determine the feasibility of batch production by a centralized intravenous additive service.

Methods: Eight empty 100-mL polypropylene bags (bags A) and 8 empty 250-mL bags (bags B) were respectively filled with 60 mL and 200 mL of 5-mg/mL acyclovir and 0.9% sodium chloride injection (NaCl) under aseptic conditions through a semiautomated manufacturing process and vacuum packed before storage at 5°C ± 3°C.

Nucleotide lipid-based hydrogel as a new biomaterial ink for biofabrication.

One of the greatest challenges in the field of biofabrication remains the discovery of suitable bioinks that satisfy physicochemical and biological requirements. Despite recent advances in tissue engineering and biofabrication, progress has been limited to the development of technologies using polymer-based materials. Here, we show that a nucleotide lipid-based hydrogel resulting from the self-assembly of nucleotide lipids can be used as a bioink for soft tissue reconstruction using injection or extrusion-based systems.

Simulation program of a cytotoxic compounding robot for monoclonal antibodies and anti-infectious sterile drug preparation.

The aim of this study was to develop a specific simulation program for the validation of a cytotoxic compounding robot, KIRO® Oncology, for the preparation of sterile monoclonal antibodies and anti-infectious drugs. The impact of excipient formulations was clearly measured using simulation accuracy tests with worst case excipient (i.e.

Micro- and nano-formulations for bioprinting and additive manufacturing.

Recent developments in bioprinting have enabled an optimized formulation of bioinks by incorporating pharmaceuticals into cell-containing gel matrices. The proof-of-printability of a variety of forms has been provided, such as particles and fibers in the nanometric or micrometric range like dendrimers or micelles, although this is still lacking for some (liposomes for example). Resulting composite bioinks have the advantage of (i) improving cell growth and differentiation, (ii) delivering active molecules or (iii) improving mechanical properties of bioinks, printed scaffolds or the printing process.

Formulation and characterization of a 0.1% rapamycin cream for the treatment of Tuberous Sclerosis Complex-related angiofibromas.

Medicines for the treatment of rare diseases frequently do not attract the interest of the pharmaceutical industry, and hospital pharmacists are thus often requested by physicians to prepare personalized medicines. Tuberous Sclerosis Complex (TSC) is a rare disease that causes disfiguring lesions named facial angiofibromas. Various topical formulations of rapamycin (=sirolimus) have been proved effective in treating these changes in small case series.
