The present invention provides a pH dependent vaginal composition delivering a therapeutically effective amount of at least one active essentially at a pH above 4.5. The composition provides a diagnostic visual pH indication of the presence of vulvovaginitis at pH above 4.5. In the absence of such indication, the treatment may be discontinued. Another visual signal is the retrieval of the unchanged composition, which also points to a normal pH at or below 4.5 and absence of vulvovaginitis.

Docetaxel and doxorubicin can be formulated in liposomal pharmaceutical compositions. In various embodiments, the pharmaceutical compositions include (i) a first liposome type comprising a first lipid layer comprising an unsaturated phospholipid, cholesterol or a cholesterol derivative, DC-cholesterol, a cationic lipid, and preferably a pegylated phospholipid, and a first active pharmaceutical ingredient (API) comprising docetaxel in the first lipid layer; and (ii) a second liposome type comprising a second lipid layer, an aqueous interior, and a second API comprising doxorubicin crystallized in the aqueous interior, (iii) where the first liposome type does not comprise doxorubicin and the second liposome type does not comprise docetaxel. The pharmaceutical composition can be used to treat a subject, for example, a human subject having cancer. The cancer can be, for example, a lung cancer, preferably non-small cell lung cancer (NSCLC), colon cancer, breast cancer, or liver cancer, preferably hepatocellular carcinoma (HCC).

A liposome composition, which is obtained by mixing a water-miscible organic solution in which a phospholipid and cholesterol are contained in a total concentration of 100 to 200 w/v % in a water-miscible organic solvent with a first aqueous phase solution in an amount of 3/1 to 12/1 in terms of volume ratio to the water-miscible organic solution, thereby obtaining an emulsion in which the total concentration of the phospholipid and cholesterol in the resulting mixed phase is 15 to 50 w/v %, followed by subjecting the emulsion to external solution exchange with a second aqueous phase solution, wherein an ion gradient is formed between an aqueous phase in an internal region of a liposome membrane, including the first aqueous phase solution, and an aqueous phase in an external region of the liposome membrane, including the second aqueous phase solution, and a drug can be introduced in a high encapsulation amount.

Compositions and methods for the treatment of tuberculosis, as well as other mycobacterial and gram positive bacterial infections are disclosed. These compositions contain a highly potent and selective oxazolidinone encapsulated with high efficiency to maximize dosing potential of low toxicity drugs, and are stable in the presence of plasma. The compositions are long circulating and retain their encapsulated drug while in the circulation following intravenous dosing to allow for efficient accumulation at the site of the bacterial or mycobacterial infection. The high doses that can be achieved when combined with the long circulating properties and highly stable retention of the drug allow for a reduced frequency of administration when compared to daily or twice daily administrations of other drugs typically utilized to treat these infections.

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.
