摘要:
A parenteral azole composition comprises a first solvent, made of benzyl alcohol and/or an acidified alcohol such as ethanol, and a lipophilic component such as PEG400, and the azole, or triazole, such as itraconazole or posaconazole dissolved in this first composite solvent vehicle that is essentially free of surfactants, particularly non-ionic surfactants, and has low levels of water, preferably less than 5% water. The composition may be further diluted with an infusion fluid, such as normal saline or 5% or 10% dextrose in water, before infusion into an immunocompromized mammal, preferably a human. The composition is useful for the treatment and suppression of infections caused by microbes such as yeast and molds that are sensitive to azoles, but it may be extended to dissolve other pharmaceutically active agents that can be used to treat other types of infectious diseases or other ailments, such as malignant and autoimmune diseases.
摘要:
There may be provided compositions of lipophilic pharmaceutical agents with improved solubility and stability. For example, there may be provided a non-aqueous composition that comprises a lipophilic pharmaceutical agent, and an amphiphilic polymeric solvent such as PEG400 but essentially free of organic solvents and non-solubilized particles. The composition may be further diluted with a desired aqueous diluent such as an infusion fluid for parenteral administration to a subject such as a human. The compositions may be useful for the treatment for diseases or conditions that are sensitive to lipophilic agents, such as infectious diseases, malignant or autoimmune diseases.

摘要:
A model of systemic mold/Aspergillus infection in a profoundly immunocompromised host has been established in the beagle dog. The beagle was rendered immunosuppressed using a combination of total body irradiation and daily steroids, which provided a window of time where the mold could be successfully inoculated through a bronchoscope. This created a localized infection in one lung lobe, which subsequently spread diffusely throughout the lung parenchyma, and uniformly resulted in the animal's death. The invention contemplates the further study of the pathophysiology of opportunistic mold infections in vivo and also provides examples for the development of new antifungal agents and more effective combinations of agents. Finally, the invention contemplates the development of technology for the early detection of systemic mold infections. The inventors envision, that the use of the model should help save patients from clinical trials of antifungal drugs that may be effective in vitro without living up to the expectations in a clinical setting.
摘要:
Stable parenteral formulations of busulfan for parenteral administration are disclosed. The improved bioavailability of the parenteral formulations optimizes high dose busulfan therapy against malignant disease and improves the safety of such therapy.
摘要:
An antifungal composition suitable for parenteral administration to a mammal includes an amount of pimaricin or an antifungal derivative thereof that is effective to inhibit the growth of a fungal infection in a mammal; a pharmaceutically acceptable dipolar aprotic solvent; and a pharmaceutically acceptable aqueous secondary solvent. The composition can be used in methods of preventing or treating a systemic fungal infection in a mammal. The composition can be prepared by dissolving pimaricin or an antifungal derivative thereof in the pharmaceutically acceptable dipolar aprotic solvent; adding to the solution a pharmaceutically acceptable aqueous secondary solvent; and in a preferred method, by subsequently lypohilizing the composition, whereby a dry, shelf-stable composition is produced. This dry composition can be reconstituted into an aqueous solution suitable for parenteral administration.
摘要:
Disclosed is a stable and effective formulation of a taxane analog, preferably paclitaxel. The formulation comprises a dimethylacetamide and polyethylene glycol solution of the drug that is diluted into an aqueous lipid emulsion prior to use. The formulation is effective as a parenterel drug against taxane sensitive tumors.
