The feasibility of producing proliposomes containing curcumin, as well as liposome dispersions, using different mixtures of purified and nonpurified soybean phospholipids was studied. Proliposomes were produced through coating of micronized sucrose and physicochemically characterized over 30 days of storage. In addition, the possible interactions among the components were investigated using X-ray powder diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The proliposomes demonstrated a low propensity of water adsorption and low hygroscopicity. In addition, the curcumin content retained in the powders ranged from 67 to 92%. The liposomes were produced following proliposome hydration. Atomic force microscopy indicated the vesicles presented spherical shapes and photon correlation spectroscopy detected that their hydrodynamic diameters ranged from 207 to 222 nm. Finally, the curcumin-loaded liposomes preserved up to 63% of the bioactive compound but remained stable for only 15 days of storage.

This study presents a novel approach using polyol-based proliposome to produce marine phospholipids nanoliposomes. Proliposomes were formulated by blending glycerol with phospholipids across varying mass ratios (2:1 to 1:10) at room temperature. Analysis employing polarized light microscopy, FTIR, and DSC revealed that glycerol disrupted the stacked acyl groups within phospholipids, lowering the phase transition temperature (T).

Drug delivery via aerosolization for localized and systemic effect is a non-invasive approach to achieving pulmonary targeting. The aim of this study was to prepare spray-dried proliposome (SDP) powder formulations to produce carrier particles for superior aerosolization performance, assessed via a next generation impactor (NGI) in combination with a dry powder inhaler. SDP powder formulations (F1-F10) were prepared using a spray dryer, employing five different types of lactose carriers (Lactose monohydrate (LMH), lactose microfine (LMF), lactose 003, lactose 220 and lactose 300) and two different dispersion media.

Pulmonary tuberculosis (TB) is a worldwide life-threatening infection. Therecommended anti-TB regimen contains oral administration of classical first-line drugs suchas rifampin for 6-24 months which often leads to low patient compliance due to high adverseeffects; therefore, lung localized pulmonary delivery of anti-TB agents may be a suitablealternative. Proliposomes free-flowing powders are well-known carriers for lung delivery sincethey can form liposomes by hydration.

Biological activity of essential oils (EOs) has been extensively reported; however, their low aqueous solubility, high photosensitivity, and volatility compromise a broad industrial use of these compounds. To overcome these limitations, we proposed a nanoencapsulation approach to protect EOs, that aims to increase their stability and modulate their release profile. In this study, drug-in-cyclodextrin-in-liposomes encapsulating two essential oils ( and ) and their respective major compounds (thymol and eugenol) were produced by ethanol injection and freeze-dried to form proliposomes and further physicochemically characterized.

Introduction: Ketoprofen (K) was synthesized in 1968. K belongs to nonsteroidal anti-inflammatory drugs (NSAIDs) and has analgesic, anti-inflammatory and antipyretic properties. K is commonly used due to rapid absorption, simple metabolism, high antinociceptive activity and fast blood brain barrier crossing.
