These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Purpose This study evaluated the stability of diluted insulin aspart solutions (containing insulin aspart and preservatives) at their most commonly used concentration in intensive care units (1 unit/mL), in 2 container types: cyclic olefin copolymer (COC) vials and polypropylene (PP) syringes. Methods Insulin aspart solution (1 unit/mL, diluted in 0.9% sodium chloride injection) was stored for 365 days in COC vials with gray stoppers and PP syringes at refrigerated (5±3°C) and ambient temperatures (25°C ± 2°C at 60% ± 5% relative humidity and protected from light). Chemical testing was conducted monthly using a validated high-performance liquid chromatography method (quantification of insulin aspart, phenol, and metacresol). Physical stability was evaluated monthly via pH measurements, visible and subvisible particle counts, and osmolality measurements. Sterility testing was also performed to validate the sterile preparation process and the maintenance of sterility throughout the study. Results The limit of stability was set at 90% of the initial concentrations of insulin aspart, phenol, and metacresol. The physicochemical stability of 1-unit/mL insulin solutions stored refrigerated and protected from light, was unchanged in COC vials for the 365-day period and for 1 month in PP syringes. At ambient temperature, subvisible particulate contamination as well as the chemical stability of insulin and metacresol were acceptable for only 1 month’s storage in PP syringes, while insulin chemical stability was maintained for only 3 months’ storage in COC vials. Conclusion According to our results, it is not recommended to administer 1-unit/mL pharmacy-diluted insulin solutions after 3 months’ storage in COC vials at ambient temperature or after 1 month in PP syringes at ambient temperature. The findings support storage of 1-unit/mL insulin aspart solution in COC vials at refrigerated temperature as the best option over the long term. Sterility was maintained in every condition. Both sterility and physicochemical stability are essential to authorize the administration of a parenteral insulin solution.

Background Cytarabine is widely used to treat leukemia and lymphoma. Currently, Cyrabol®, powder for injection, is one of the specialties marketed in Tunisia. However, no stability data when diluted with 0.9% NaCl are available. The aim of this study is to evaluate the physical and chemical stability of cytarabine (Cyrabol®) solution after dilution in 0.9% NaCl (1 mg/mL, 5 mg/mL and 10 mg/mL) in polypropylene syringes under different storage conditions. Methods Cytarabine solutions (1 mg/mL, 5 mg/mL and 10 mg/mL) in 0.9% NaCl were prepared in polypropylene syringes and stored for 28 days under different conditions. Cytarabine preparations in glass containers were prepared as a control to detect any adsorption. Chemical stability was assessed by a stability-indicating high-performance liquid chromatography method. The stability-indicating capacity of the method was proved by forced degradation tests. Linearity, precision and limit of detection and quantification were performed according to the International Conference on Harmonisation recommendations. Physical stability was checked by visual inspection. Results The method was proven to be a validated stability-indicating assay. At 2–8°C, all tested solutions were chemically stable for 28 days. However, at 25°C, the main degradation product gradually increased during the study and the chemical stability of 1 mg/mL, 5 mg/mL and 10 mg/mL solutions was 14 days, 8 days and 5 days, respectively. Similar results were observed in the glass containers. Conclusion The highest physical and chemical stability of cytarabine diluted in 0.9% NaCl in polypropylene syringes was observed at 2–8°C. At 25°C, better stability was found in the 1 mg/mL solution compared with those at higher concentrations (5 mg/mL and 10 mg/mL).

Objective: At present, the nail preparation to cure onychomycosis, caused by non-dermatophyte molds, is not commercially available in Thailand. The physical and chemical stability of amphotericin B (AmB) extemporaneous preparations in the presence of 30% dimethyl sulfoxide (DMSO) and their in vitro nail permeation was evaluated. Methods: AmB extemporaneous preparations in the presence of 30% DMSO were prepared from a commercial sterile injection product, and cream or hydrophilic ointment. Physical stability was tested at 30°C for 2 months, or using 6 heating-cooling cycles. The chemical stability and in vitro nail permeation of AmB content were analyzed using high-performance liquid chromatography (HPLC). In vitro nail permeation was performed by applying 3.5 mg/mm2 of the tested formulation on nail clippings for 5 consecutive days. Results: The AmB cream and ointment extemporaneous preparations containing 30% DMSO, a permeation enhancer, were homogeneous and pale yellow to yellow cream or ointment. The AmB ointment was stable for up to 60 days. The ointment preparation allows in vitro penetration through nails up to 14.17 μg/cm2. The ointment preparation allows significantly better penetration through than the cream preparation due to the presence of DMSO, sodium lauryl sulfate (SLS), and water in the ointment preparation. Conclusion: The AmB extemporaneous ointment was successfully compounded from a commercial sterile injection product with a beyond-use date of 60 days. The ointment preparation is currently under further investigation for in vivo efficacy.

The objective of this study was to evaluate the physical and chemical stability of imipenem-cilastatin sodium 250 mg/100 mL and 500 mg/100 mL (of each drug component) admixed in 0.9% sodium chloride injection packaged in AutoDose Infusion System bags. Triplicate test samples were prepared by bringing the required amount of imipenem-cilastatin sodium injection to volume with 0.9% sodium chloride injection. A total of 100 mL of each of the test solutions was packaged in each of three ethylene vinyl acetate (EVA) AutoDose bags designed for use in the AutoDose Infusion System for each storage condition. Samples were protected from light and evaluated at appropriate intervals for up to three days at 23°C and 14 days at 4°C. Physical stability was assessed using a multistep evaluation procedure that included turbidimetric and particulate measurement in addition to visual inspection. Chemical stability was assessed with stability-indicating high performance liquid chromatography (HPLC) analytical techniques, based on initial drug concentrations and concentrations at appropriate intervals over the study periods. The admixtures were clear throughout the study when viewed in normal fluorescent room light and with a Tyndall beam. Measured turbidity and particulate content were low initially and exhibited little change throughout the study. HPLC analysis revealed extensive decomposition in the samples, with imipenem being the less stable component. The instability of the imipenem-cilastatin sodium admixtures is consistent with previous studies. Admixtures stored under refrigeration should be used immediately upon warming to room temperature due to the rapid rate of imipenem decomposition. The AutoDose Infusion System bags were not found to affect adversely or improve the physical and chemical stability of this drug.

The objective of this study was to evaluate the physical and chemical stability of vincristine sulfate diluted to a variety of concentrations in 0.9% sodium chloride injection and packaged in minibags and 30 mL syringes, to help deter inadvertent intrathecal injection of the drug. Test samples were prepared by diluting vincristine sulfate quantities of 0.5 mg, 1 mg, 2, mg, and 3 mg in 0.9% sodium chloride injection. These quantities were selected to span the range of doses normally expected for this cytotoxic drug. The vincristine was diluted with 0.9% sodium chloride injection in volumes of 25 mL and 50 mL packaged in polyvinyl chloride minibags and to 20 mL packaged in 30 mL polypropylene syringes. Physical and chemical stability evaluations were performed initially and after 1, 3, and 7 days of storage at 4°C followed by an evaluation at 9 days after 2 additional days of storage at a temperature of 23°C. Physical stability was assessed using visual observation in normal light and a high-intensity monodirectional light beam. In addition, turbidity and particle content were measured electronically. Chemical stability of the drug was evaluated by using a stability-indicating high performance liquid chromatographic (HPLC) analytical technique. No physical instability was noted and no unacceptable loss of vincristine sulfate concentration was found in any sample throughout the study period. The use of vincristine sulfate doses diluted in infusion volumes of 0.9% sodium chloride injection and packaged in minibags or in 30 mL syringes to help deter inadvertent intrathecal administration may be performed with no unacceptable physical or chemical instability occurring.

Abstract 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. Four bags A and 4 bags B were tested for chemical stability via a stability-indicating high-performance liquid chromatography (HPLC) method immediately after preparation (time 0) and after 7, 14, 21, 28, 35, 42, and 63 days. Samples for microbiological assay were collected on days 0 and 63 from 4 bags A and 4 bags B immediately after breaking the vacuum. Osmolality, pH, and physical stability were assessed by visual examination, Subvisible particle counting was performed on 6 additional bags (3 each of bags A and B). Results Mean percentage loss of acyclovir relative to the mean experimental concentration at time 0 was below 5% over the 63-day study period.. No significant differences of pH, no change in color and no precipitate were observed during the study. Subvisible particle counts were compliant with European Pharmacopoeia requirements. Acyclovir solutions remained sterile over the 63 days of the study. Conclusion Extemporaneously prepared acyclovir 5 mg/mL solutions in 0.9% NaCl stored in polypropylene bags were chemically and physically stable over 63 days when stored at 5°C ± 3°C.

BACKGROUND: Postoperative patient-controlled analgesia provides pain relief, encourages early mobilization, and results in a shortened hospital stay. Patient-controlled analgesia involves the mixing of different types of drugs. When using patient-controlled analgesia, it is important to confirm the microbiological and physicochemical stability of each drug in a mixture to guarantee that the drug is delivered to the patient in an unaltered form. OBJECTIVES: To confirm the microbiological and physicochemical stability of various drug mixtures for intravenous patient-controlled analgesia. STUDY DESIGN: An in vitro protocol to examine the microbiological and physicochemical stability of the most commonly used postoperative intravenous patient-controlled analgesia mixtures at our institution. SETTING: In vitro laboratory study. METHODS: Each mixture contained a total of 4 drugs: fentanyl 400 µg, ketorolac 30 mg, either hydromorphone 4 mg or oxycodone 10 mg, and either ramosetron 0.3 mg or ondansetron 10 mg. Each mixture was placed in a portable patient-controlled analgesia system containing 0.9% saline and stored at a constant temperature of 24°C for 96 hours. Physical properties (color, transparency, and sedimentation) were observed with the naked eye and optical microscopy. Sterility testing was performed to assess microbiological contamination in the drug mixture during the 96-hour study period. The pH of each mixture was evaluated for up to 96 hours after mixing. The concentration of each drug was evaluated by high-performance liquid chromatography every 24 hours until 96 hours after mixing. RESULTS: All mixtures appeared visibly transparent, and no sediments were visible under the microscope. Bacterial or fungal growth was not observed in any of the samples after 14 days of incubation. The pH variations in all mixtures were maintained within 0.25 over the 96-hour study period. The concentration of drugs, except ketorolac, ranged from 90–110% of the initial concentration up to 96 hours after mixing. In the mixtures with a pH of 4.21–4.39, the concentration of ketorolac significantly decreased at 24 hours and 48 hours. LIMITATIONS: Confirmation of the stability of drugs in vitro does not automatically ensure that the pharmacokinetics and pharmacodynamics of the drugs are not altered in vivo. CONCLUSION: With the exception of ketorolac, the drugs used in the intravenous patient-controlled analgesia drug mixtures in this study were physicochemically stable up to 96 hours after mixing. The concentration of ketorolac decreased in more acidic mixtures.
