According to several studies, liposomes can enhance the absorption of water-soluble active substances compared to when they are not encapsulated in liposomes. Liposomes, which mimic natural cell membranes, have been extensively studied as drug carriers due to their entrapment capacity, biocompatibility, and safety.
Research has shown that liposomal technology can improve the breakdown and absorption of both oil and water-soluble molecules in target cells. This enhancement in absorption is particularly beneficial for water-soluble compounds that may have lower bioavailability or face challenges in crossing biological barriers.
The incorporation of water-soluble active pharmaceutical ingredients (APIs) into liposomes has been found to increase their oral absorption. Studies have investigated the effect of liposomes on the absorption of water-soluble APIs, such as salbutamol sulfate and other pharmaceutical substances, and have reported positive results.
It is important to note that the effectiveness of liposomes in enhancing absorption may depend on various factors, including the specific active substance, liposome formulation, dosage form, and route of administration.

PureNSM can create the above liposomes for water soluble actives like described above, however we would like the end product to be liquid. If you want to create liposomes with hydrophobic (oil soluble) ingredients, see below, then we can both deliver them in powder or liquid form. If you choose powder form then we recommend inclusion with cyclodextrin. Much like with liposomes, cyclodextrins prefer hydrophobic actives. What is very interesting is that once we have the cyclodextrin with the actives, we can then create an Extended-Slow-Release tablet.
We would recommend we mix both non-liposomal and liposomal actives with the cyclodextrin.
Liposomes created with oil-soluble actives are stronger and more robust than those created with water-soluble actives due to the nature of liposomes themselves. Liposomes are lipid-based vesicles composed of a phospholipid bilayer, which is essentially a double layer of fats. Since oil-soluble actives have a similar lipid structure, they can easily be incorporated into the lipid bilayer of liposomes without compromising the stability and integrity of the vesicles.
On the other hand, water-soluble actives do not readily integrate into the lipid bilayer of liposomes because of their hydrophilic (water-loving) nature. Incorporating water-soluble actives into liposomes often requires additional steps, such as altering the composition of the liposome formulation or using specialized techniques like thin-film hydration or reverse-phase evaporation.
By contrast, the lipophilic (fat-loving) nature of oil-soluble actives allows them to seamlessly integrate into the lipid bilayer of liposomes, resulting in a more straightforward encapsulation process. This compatibility simplifies the formulation process and enhances the stability and bioavailability of oil-soluble actives within liposomal delivery systems.
