Sustained-release compositions comprising a therapeutic agent for treating depression or anxiety and uses thereof
The present invention relates to a pharmaceutical composition comprising at least one liposome and a therapeutic agent for treating depression or anxiety, with a therapeutic agent to lipid ratio equal to or higher than about 0.15. The pharmaceutical composition improves the pharmacokinetic profile and sustains the release of the therapeutic agent. Also provided is the method for treating depression or anxiety using the pharmaceutical composition disclosed herein.
LIPOSOME COMPOSITIONS COMPRISING WEAK ACID DRUGS AND USES THEREOF
The present invention relates to a pharmaceutical composition comprising a weak acid drug, with the use of a bicarbonate salt to achieve a high incorporation of the drug into the liposome and a better therapeutic efficacy. Also disclosed is a method for treating a respiratory disease using the pharmaceutical composition disclosed herein.
STABLE NANOLIPOPROTEIN PARTICLES AND RELATED COMPOSITIONS METHODS AND SYSTEMS
Nanolipoprotein particles having at least a scaffold protein component and a membrane lipid component and related compositions, methods and systems are described. The membrane lipid component includes at least one or more membrane forming lipids, one or more polymerized lipids and/or one or more polymerizable lipids.
Acid stable liposomal compositions and methods for producing the same
The present invention relates to a liposomal formulation for oral delivery of a bioactive agent that considers pH stability and oxidative stability of a bioactive ingredient. These lipid formulations are superior to conventional liposomes due to their stability, thereby circumventing the need for intra-venous delivery of bioactive agents. In one embodiment, the methods and compositions of the present invention relate to the oral delivery of insulin or a prodrug thereof.
REMOTE LOADING OF SPARINGLY WATER-SOLUBLE DRUGS INTO LIPOSOMES
The present invention provides liposome compositions containing sparingly soluble drugs that are used to treat life-threatening diseases. A preferred method of encapsulating a drug inside a liposome is by remote or active loading. Remote loading of a drug into liposomes containing a transmembrane electrochemical gradient is initiated by co-mixing a liposome suspension with a solution of drug, whereby the neutral form of the compound freely enters the liposome and becomes electrostatically charged thereby preventing the reverse transfer out of the liposome. There is a continuous build-up of compound within the liposome interior until the electrochemical gradient is dissipated or all the drug is encapsulated in the liposome. However, this process as described in the literature has been limited to drugs that are freely soluble in aqueous solution or solubilized as a water-soluble complex. This invention describes compositions and methods for remote loading drugs with low water solubility (<2 mg/mL). In the preferred embodiment the drug in the solubilizing agent is mixed with the liposomes in aqueous suspension so that the concentration of solubilizing agent is lowered to below its capacity to completely solubilize the drug. This results in the drug precipitating but remote loading capability is retained. The process is scalable and, in liposomes in which the lipid composition and remote loading agent are optimized, the resulting drug-loaded liposomes are characterized by a high drug-to-lipid ratios and prolonged drug retention when the liposome encapsulated drug is administered to a subject.
Stabilizing Camptothecin Pharmaceutical Compositions
Irinotecan phospholipid liposomes with improved storage stability are provided, with related methods of treatment and manufacture. The irinotecan liposomes can have reduced formation of lyso-phosphatidylcholine (lyso-PC) during storage, and prior to administration to a patient.
Thermosensitive nanoparticle formulations and method of making the same
The present invention relates to a formulation of thermosensitive liposomes, and more specifically to a formulation of liposomes comprising phospholipids and a surface active agent, wherein the liposomes support long term storage at temperatures less than or equal to about 8 C., control degradate formation to maximize product potency and release their contents at mild hyperthermic temperatures. Methods of making formulations are also described.
RGD PEPTIDE AND PENETRATING PEPTIDE R8 CO-MODIFIED ERGOSTEROL AND CISPLATIN ACTIVE DRUG-LOADING LIPOSOME
The presently disclosed subject matter is directed to an RGD peptide and penetrating peptide R8 co-modified ergosterol and cisplatin active drug-loading liposome that is prepared by means of the incubation of an ergosterol and cisplatin active drug-loading liposome, RGD cyclic peptide, and penetrating peptide R8 in a water bath. The ergosterol and cisplatin active drug-loading liposome is prepared from an ergosterol liposome and a cisplatin solution serving as the raw materials. The ergosterol liposome is prepared from 8 wt % to 15 wt % ergosterol and 85 wt % to 92 wt % liposomes, and the liposomes consist of lecithin and cholesterol.
Liposome composition
The present invention provides a novel liposome composition containing eribulin or its pharmacologically permissible salt, and its method of manufacture.
Compositions and methods for treating or preventing multiple organ dysfunction syndrome
A PN composition for treating multiple organ dysfunction syndrome (MODS) comprises a lipophilic or hydrophobic component, an amphiphilic emulsifier, a polar liquid carrier, and one or more electrolytes, where the amphiphilic emulsifier forms micelles having a lipophilic or hydrophobic core comprising the lipophilic or hydrophobic component in the polar liquid carrier, and/or liposomes organized as a lipid bilayer and/or other particle configurations. This is a PN composition that takes up nitric oxide and releases it with enhanced rapidity enabling it to shift the balance of nitric oxide from one that exacerbates organ damage and decreased survivability to one that reverses and/or inhibits organ damage and increases survivability.
