Current cannabidiol (CBD) formulations are challenged with unpredictable release and absorption. Rational design of a rectal colloid delivery system can provide a practical alternative In this study the inherent physiochemical properties of transferosomes were harnessed for the development of a nano-sized transfersomes to yield more stable release, absorption, and bioavailability of CBD as a rectal colloid. Transfersomes composed of soya lecithin, cholesterol, and polysorbate 80 were synthesized via thin film evaporation and characterized for size, entrapment efficiency (%), morphology, CBD release, ex vivo permeation, and physicochemical stability. The optimized formulation for rectal delivery entrapped up to 80.0 ± 0.077% of CBD with a hydrodynamic particle size of 130 nm, a PDI value of 0.285, and zeta potential of -15.97 mV. The morphological investigation via SEM and TEM revealed that the transfersomes were spherical and unilamellar vesicles coinciding with the enhanced ex vivo permeation across the excised rat colorectal membrane. Furthermore, transfersomes improved the stability of the encapsulated CBD for up to 6 months at room temperature and showed significant promise that the transfersomes promoted rectal tissue permeation with superior stability and afforded tunable release kinetics of CBD as a botanical therapeutic with inherent poor bioavailability.

Phytochemicals have been effectively used to enhance the growth and productivity of farm animals, while the potential roles of essential oils and their nano-emulsions are limited. This plan was proposed to investigate the impacts of orally administered moringa oil (MO) or its nano-emulsion (NMO) on the growth, physiological response, blood health, semen attributes, and sperm antioxidant-related genes in rams. A total of 15 growing Rahmani rams were enrolled in this study and allotted into three groups.

Ulcerative colitis is a recurring condition that causes inflammation and sores in the digestive system. Current clinical treatments for ulcerative colitis have limitations due to side effects and poor patient compliance. This study investigates the therapeutic potential of a novel drug delivery system, CA-Gel, which comprises caffeic acid (CA) stabilized by pectin nanoparticles within a poloxamer thermosensitive gel for rectal administration.

Background: Budesonide (BUD) is a BCS class II medication with poor water solubility and limited oral bioavailability. In this study, innovative solid self-microemulsifying drug delivery systems (BUD-SMEDDS) were developed for effective local management of distal ulcerative colitis (UC).

Methods: Based on solubility and emulsification tests, the components of the self-microemulsifying drug delivery system (SMEDDS) were Capryol™ 90, Tween 80, and Transcutol HP.

Article Synopsis
  • Patchouli essential oil (PEO) shows promise for managing ulcerative colitis (UC) but is limited by poor absorption and stability.
  • A new nanoemulsion of PEO (PEONE) was created to improve its effectiveness for rectal delivery using a dual-sensitive hydrogel that helps target the inflammation site.
  • The PEONE@RTH formulation has been shown to reduce inflammation and oxidative stress in UC while also being safe and biocompatible, offering a potential new treatment strategy for UC and related intestinal disorders.
