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.

OBJECTIVE: To evaluate the physical compatibility and chemical stability of paclitaxel at concentrations of 0.3 and 1.2 mg/mL with cisplatin 0.2 mg/mL in NaCl 0.9% injection and with carboplatin 2 mg/mL in NaCl 0.9% injection and dextrose 5% injection over 7 days at 4, 23, and 32°C. DESIGN: The test samples were prepared in polyolefin bags of the infusion solutions at the required drug concentrations. Evaluations were performed initially and after 4 hours, and 1, 3, 5, and 7 days of storage at temperatures of 4, 23, and 32°C for physical and chemical stability. Physical stability was assessed by using visual observation in normal light and using a high-intensity monodirectional light beam. In addition, turbidity and particle content were measured electronically. Chemical stability of the three drugs was evaluated by using three stability-indicating HPLC analytical techniques. RESULTS: All samples were physically stable through 1 day. However, microcrystalline precipitation of paclitaxel occurred in 3 days in some samples and within 5 days in all samples. Paclitaxel concentrations remained above 90% in all samples throughout the study. Cisplatin admixtures exhibited paclitaxel concentration-dependent decomposition with cisplatin losses of approximately 5–8% in 4 hours and approximately 20% in 1 day at 23 and 32°C in the paclitaxel 1.2 mg/mL admixtures. With paclitaxel 0.3 mg/mL in the admixtures, cisplatin losses were about 10% in 7 days at these temperatures. Carboplatin in admixtures with both concentrations of paclitaxel was stable for 7 days at 4°C, but sustained losses of about 10% and 12% in 3 days at 23 and 32°C, respectively. CONCLUSIONS: Admixtures of paclitaxel 0.3 and 1.2 mg/mL with cisplatin and carboplatin are limited in their utility time by both paclitaxel microcrystalline precipitation and decomposition of cisplatin and carboplatin. The admixture of paclitaxel 1.2 mg/mL with cisplatin 0.2 mg/mL in NaCl 0.9% injection exhibits unacceptable cisplatin loss in 24 hours. All other combinations were physically and chemically stable for at least 24 hours at 4, 23, and 32°C.

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.

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.

OBJECTIVE: To evaluate the physical compatibility and chemical stability of paclitaxel at concentrations of 300 and 1200 μg/mL with doxorubicin hydrochloride 200 μg/mL in NaCl 0.9% injection and dextrose 5% injection over 7 days at 4, 23, and 32 °C. DESIGN: The test samples were prepared in polyolefin bags of the infusion solutions at the required drug concentrations. Evaluations were performed initially and after 4 hours, and 1, 3, 5, and 7 days of storage at 4, 23, and 32 °C for physical and chemical stability. Physical stability was assessed by using visual observation in normal fluorescent light and a high-intensity monodirectional light beam. In addition, turbidity and particle content were measured electronically. Chemical stability of the two drugs was evaluated by using two stability-indicating HPLC analytic techniques. RESULTS: All samples were physically stable through 1 day. However, microcrystalline precipitation of paclitaxel occurred within 3 days in some samples and within 5 days in all samples. Paclitaxel concentrations remained at more than 97% in all samples throughout the study. Doxorubicin hydrochloride also was stable throughout the study period, remaining above 90% in all samples at all storage temperatures. CONCLUSIONS: Admixtures of paclitaxel 300 and 1200 μg/mL with doxorubicin hydrochloride are limited in their utility time by paclitaxel microcrystalline precipitation. All combinations were physically and chemically stable for at least 24 hours at 4, 23, and 32 °C.

Abstract Purpose To evaluate the physical and chemical compatibilities of treprostinil sodium and dopamine hydrochloride. Methods Treprostinil sodium (4,000, 76,000, and 500,000 ng/mL) were mixed with dopamine hydrochloride (0.6, 3.2, 6, and 40 mg/mL). Samples were obtained at hours 0, 1, 2, and 4 for physical compatibility and chemical stability testing. Physical compatibility was assessed by visual examination and measurements of turbidity and pH. Drug concentrations were assessed using stability-indicating liquid chromatography mass spectrophotometry (LCMS) for treprostinil sodium and stability-indicating high-performance liquid chromatography (HPLC) for dopamine hydrochloride. Results Treprostinil sodium 4,000 and 76,000 ng/mL, when mixed with dopamine hydrochloride 0.6, 3.2, 6, and 40 mg/mL, were stable for 4 hours. Treprostinil sodium 500,000 ng/mL was stable when mixed with dopamine hydrochloride 0.6 mg/mL for 4 hours, but when mixed with dopamine hydrochloride 3.2, 6, and 40 mg/mL, significant precipitation was seen. Conclusion Treprostinil sodium 4,000 and 76,000 ng/mL were stable for 4 hours during simulated Y-site coadministration with dopamine hydrochloride 0.6, 3.2, 6, and 40 mg/mL. Treprostinil sodium 500,000 ng/mL is stable when mixed with dopamine hydrochloride 0.6 mg/mL.

OBJECTIVE: To evaluate the physical and chemical stability of cefepime (as the hydrochloride) 1 g/100 mL and 4 g/100 mL admixed in NaCl 0.9% injection and packaged in AutoDose Infusion System bags. DESIGN: Triplicate test samples of cefepime hydrochloride in NaCl 0.9% injection were packaged in ethylene vinyl acetate plastic containers, AutoDose bags, designed for use in the AutoDose Infusion System. Samples were stored protected from light and evaluated at appropriate intervals for up to 7 days at room temperature of approximately 23 °C and 30 days under refrigeration at 4 °C. Physical stability was assessed using turbidimetric and particulate measurement, as well as visual inspection. Chemical stability was assessed by HPLC. RESULTS: All of the admixtures were initially clear and light yellow when viewed in normal fluorescent room light and with a Tyndall beam. Measured turbidity and particulate content were low initially but increased over time, eventually becoming a yellow or orange precipitate. The higher concentration precipitated earlier; refrigeration slowed precipitation for both test concentrations. HPLC analysis found that the 1-g/100 mL concentration maintained adequate stability for 2 days at 23 °C and up to 30 days at 4 °C. The 4-g/100 mL concentration maintained adequate stability for 1 day at room temperature and 7 days under refrigeration; however, unacceptable drug loss and precipitation developed after those time points. CONCLUSIONS: Cefepime hydrochloride exhibited physical and chemical stability consistent with previous stability studies. The AutoDose Infusion System bags were not found to affect adversely the physical and chemical stability of this drug.

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).

BACKGROUND: Palonosetron HCl is a selective 5-HT3 receptor antagonist used for the prevention of chemotherapy-induced nausea and vomiting. Palonosetron HCl may be administered with other drugs by Y-site administration, including doxorubicin HCI and epirubicin HCI. Consequently, stability and compatability information are needed to verify the acceptability of such Y-site administration. OBJECTIVE: To evaluate the physical and chemical stability of undiluted palonosetron HCl 50 μg/mL with doxorubicin HCl 1 mg/mL and epirubicin HCl 0.5 mg/mL during simulated Y-site administration. METHODS: Triplicate samples of palonosetron HCl with each of the anthracycline chemotherapy drugs were tested. Samples were stored and evaluated for up to 4 hours at room temperature near 23°C. Physical stability was assessed using turbidimetric and particulate measurement, as well as visual inspection. Chemical stability was assessed by HPLC. RESULTS: All of the admixtures were clear and red—orange when viewed in normal fluorescent room light and with a Tyndall beam. Measured turbidity and particulate content were low initially and remained low throughout the study. The drug concentration was unchanged in any of the samples throughout the study. CONCLUSIONS: Palonosetron HCl is physically and chemically stable with doxorubicin HCl and epirubicin HCl during simulated Y-site administration of these drugs over 4 hours at ambient room temperature.

Purpose: Intravenous (IV) admixtures of diphenhydramine are widely used in hospitalized patients to prevent or treat hypersensitivity reactions. However, there is limited data to support the admixture preparation in this manner. This study was designed to investigate the stability and compatibility of diphenhydramine in IV admixtures with a goal to establish a 14-day beyond-use dating with storage under refrigeration. Methods: The commercially available 50 mg/mL diphenhydramine hydrochloride injection vials were used to prepare the 0.2 and 1.0 mg/mL IV admixtures in 0.9% sodium chloride injection and 5% dextrose injection in 50 mL polyvinyl chloride (PVC) bags. The IV bags were sealed and stored under refrigeration (2°C-8°C) for the stability study. At each predetermined time point, samples were taken for visual inspection, pH measurement, and analysis by a stability-indicating high-performance liquid chromatography (HPLC) method. Results: The freshly prepared IV admixtures appeared clear, colorless, and particulate-free with pH readings of 4.44 to 4.60. The initial drug concentrations of all samples were confirmed by HPLC to be within 101.8% to 103.6% of the label claims. Over the 14 days of the study period, there was no significant change in the appearance or pH values for all stability samples. The HPLC results also confirmed that there was no more than ±2% change of the initial drug concentration in any stability samples. Conclusion: Diphenhydramine hydrochloride IV admixtures of 0.2 and 1.0 mg/mL are compatible with 0.9% sodium chloride injection and 5% dextrose injection in PVC bags. These IV admixtures are stable chemically and physically for up to 14 days when stored under refrigeration (2°C-8°C).
