Intestinal lymphatic drug delivery has been widely studied because drugs can bypass the first-pass metabolism in the liver via the lymphatic route, which increases oral bioavailability. Various lipid-based nanoparticles have been used to deliver hydrophobic drugs to the lymphatic pathway. This review focuses on the liposomal delivery systems used for intestinal lymphatic drug transport. Liposom...

We report the penetration of liposomal amphotericin B into the pleural fluid of a patient with pulmonary zygomycosis and empyema. The ratio of area under the concentration-versus-time curve in pleural fluid (AUC(pleural fluid)) to that in serum (AUC(serum)) for liposomal amphotericin B over 24 h was 9.4%, with pleural fluid concentrations of 2.12 to 4.91 microg/ml. Given the relatively low leve...

Tumor-specific targeting is a critical goal in the research area of liposomal drug delivery. Identification of the specific interactions between ligands and target tumor cells is a principle prerequisite in achieving this goal. Generally, tumor cells aberrantly express tumor-associated antigens that can be utilized as appropriate target molecules. Monoclonal antibodies against tumor-associated ...

Cerebral malaria (CM) is a major cause of death of Plasmodium falciparum infection. Misdiagnosis of CM often leads to treatment delay and mortality. Conventional brain imaging technologies are rarely applicable in endemic areas. Here we address the unmet need for a simple, non-invasive imaging methodology for early diagnosis of CM. This study presents the diagnostic and therapeutic monitoring u...

Liposomal amphotericin B is a "true" liposomal formulation of amphotericin B with greatly reduced nephrotoxicity and minimal infusion-related toxicity. This broad spectrum polyene is well tolerated and effective against most invasive fungal infections. In view of the current limitations on diagnostic capability of invasive fungal infections, most clinicians are often compelled to use antifungal...

Pegylated liposomal doxorubicin is a formulation of doxorubicin in which the molecule itself is packaged in a liposome made of various lipids with an outer coating of polyethylene glycol. Liposomal technology is being used in increasing amounts in the therapy of a variety of cancers, including ovarian cancers. This article reviews the mechanistic actions of this formulation, the Phase II and Ph...

Glucocorticoids are highly potent anti-arthritic drugs. However, despite their efficacy a major drawback is their non-specific activity, which can result in a variety of adverse effects. We encapsulated prednisolone phosphate in PEG-liposomes aiming at enhanced local therapeutic activity at inflammatory sites and reduced systemic activity upon i.v. injection. Whole body radioscintigraphy in rat...

The aim of current study was to investigate the effect of Brij decoration of liposomes on in vitro and in vivo characteristics of the nanocarriers. Two hydrophilic Brij surfactants (Brij 35 and Brij 78) with almost similar molecular weight but differing in acyl chain were incorporated into liposomal bilayers at two percentages (5% and 10%). Conventional liposomes (CL) containing egg phosphatidy...

The liposomal cream formulation of diclofenac, an NSAID, is an effective, safe, and convenient way to treat localized areas of inflammation in horses. The results of this study reveal urinary and serum concentrations of diclofenac following topical administration of 1% liposomal diclofenac cream for 10 days at the labeled dose and at 2X and 4X the labeled dose. These results demonstrate the slo...
