Methods for quality control and optimizing the formation and characterization of micelles, vesicles or other aggregates are described herein. Pharmaceutically relevant peptides may be modified to form glycopeptide surfactants which form micelles or other aggregates with another surfactant. Glycopeptide and glycolipid surfactants can aggregate to form particles that enhance drug delivery. The glycopeptide surfactants may be drugs or prodrugs which are delivered via the micelles or other aggregated structures.

The present invention relates to pharmaceutical compositions having improved stability.

The present invention relates to pharmaceutical compositions having improved stability.

The application describes stable aqueous compositions comprising relatively high concentrations of carbetocin and a solubilizer and/or surface active agent. The disclosed carbetocin compositions are effective in the treatment of a neurodevelopmental disorder, such as Prader-Willi syndrome. Additionally, the disclosed carbetocin compositions show improved stability at room temperature and/or under accelerated conditions of stress.

A pharmaceutical or cosmetic carrier for topical administration substantially consists of phosphatidylcholine, monoglyceride, fatty acid ester of C.sub.1-C.sub.3 alcohol; volatile solvent selected from ethanol and its combinations with C.sub.3-C.sub.4 alcohol and/or volatile silicone oil. Also disclosed are pharmaceutical and cosmetic compositions comprising the carrier and pharmaceutically or cosmetically active agent(s).

A liquid pharmaceutical composition for intravenous administration that includes vasopressin or a pharmaceutically acceptable salt thereof. The formulation further includes a lactate buffer or lactic acid, optionally in combination with a pH adjuster. The pharmaceutical composition can have a pH of from about 3.0 to about 4.1 and demonstrates improved stability for long term storage, particularly at room temperature.
