Major advances in the use of liposomes, conjugates, nanoparticles, and microspheres as vehicles delivering pharmacologic agents and enzymes to sites of disease have occurred in the past 10 years (1–3). Pegylated-STEALTH liposomal doxorubicin (Doxil, Caelyx) was the first liposomal anticancer drug to be approved by the Food and Drug Administration, whereas paclitaxel albumin-bound particle suspe...
The anti-tumor efficacy of liposomal formulations of cell cycle dependent anticancer drugs is critically dependent on the rates at which the drugs are released from the liposomes. Previous work on liposomal formulations of vincristine have shown increasing efficacy for formulations with progressively slower release rates. Recent work has also shown that liposomal formulations of vincristine wit...
The objective of this study was an interspecies comparison of free nystatin (NYS) and liposomal NYS (Nyotran) distribution in plasma. NYS and liposomal NYS at concentrations of 5, 10, and 20 microg of NYS/ml were incubated in human, dog, and rat plasma for 5, 60, and 180 min at 37 degrees C. Following these incubations, plasma samples were separated into their high-density lipoprotein (HDL), tr...
BACKGROUND Treatment of central nervous system relapse in adult acute lymphoblastic leukemia is a challenge and outcome is poor. Liposomal cytarabine has a prolonged half-life and, given intrathecally, has produced high response rates in patients with central nervous system relapse of non-Hodgkin's lymphoma. The aim of this study was to evaluate the efficacy and tolerability of liposomal cytara...
Liposomal anticancer agents can effectively deliver drugs to tumor lesions, but their therapeutic effects are enhanced in only limited number of patients. Appropriate biomarkers to identify responder patients to these liposomal agents will improve their treatment efficacies. We carried out pharmacological and histopathological analyses of mouse xenograft models bearing human ovarian cancers (Ca...
OBJECTIVES Traditional antibiotic therapy of staphylococcal osteomyelitis by a single drug or a drug combination is ineffective in producing complete sterilization of infected bones. The aim of this study was to develop a non-traditional delivery system of antibiotics for treatment of chronic experimental osteomyelitis. METHODS In the current work, ciprofloxacin and vancomycin were encapsulat...
We present a case of rhino-orbitary mucormycosis which progressed despite liposomal amphotericin and early surgical debridement. Combined echinocandin and high dose liposomal amphotericin, repeated debridement, prolonged therapy with hyperbaric oxygen and continued therapy with posaconazole, along with strict diabetic control, allowed cure without disfigurement.
Ultrasound sensitive (sonosensitive) liposomes represent a drug delivery system designed for releasing a drug load upon exposure to ultrasound (US). Inclusion of dioleoylphosphatidylethanolamine (DOPE) in liposome membranes was previously shown to induce sonosensitivity. Long blood circulation time of the liposomal drug is required for high tumour uptake and efficient US-mediated drug delivery....
Objective. This report describes a case in which the off-label use of liposomal bupivacaine (Exparel) in a peripheral nerve block resulted in marked improvement of a patient's vasoocclusive symptoms. The vasodilating and analgesic properties of liposomal bupivacaine in patients with ischemic symptoms are unknown, but our clinical experience suggests a role in the management of patients sufferin...
The vitamin E analogue alpha-tocopheryl succinate (alpha-TOS) is an efficient anti-cancer drug. Improved efficacy was achieved through the synthesis of alpha-tocopheryl maleamide (alpha-TAM), an esterase-resistant analogue of alpha-tocopheryl maleate. In vitro tests demonstrated significantly higher cytotoxicity of alpha-TAM towards cancer cells (MCF-7, B16F10) compared to alpha-TOS and other a...
