Pharmacosomes Development Services

Pharmacosomes are amphiphilic lipid vesicle systems containing phospholipid complexes with the potential to enhance the bioavailability of poorly water-soluble and poorly lipophilic drugs. Protheragen-ING is a leading provider of integrated development services for pharmacosomes, delivering innovative solutions to pharmaceutical companies worldwide. Our team of experts is dedicated to assisting you at every stage of pharmacosomes development, from concept to commercialization.


Pharmacosomes can be defined as neutral molecules with optimal ratios of polyphenols to phospholipids in both positively and negatively charged, hydrophilic and lipophilic properties as well as complex forms. Drugs are present as dispersions in these lipid-based drug delivery systems, bound by electron pair sharing and electrostatic forces or by forming hydrogen bonds with lipids.

Pharmacosomes are the system of vesicles in which the drug binds to the carrier. These lipid-conjugated vesicles can exist as colloids, nanosized micelles, vesicles, or can exist as hexagonal assemblies with functional hydrogen atoms based on the structure of the complex.

Materials for Pharmacosomes

The following components may be utilized for the preparation of pharmacosomes.

Component Requirement
Drugs Functional hydrogen atoms from amino, carboxyl, or hydroxyl groups that can be esterified
Solvents  High purity, volatile, and intermediate polarity
Lipid Phospholipids-phosphoglyceride or sphingolipids

Preparation of Pharmacosomes

To form pharmacosomes, drug-lipid complexes are required. The salt form of the drug is converted to an acidic form to expose functional hydrogen atoms and form complexes. The aqueous solution of the drug was acidified, extracted with chloroform, and then recrystallized. The equimolar phospholipid concentration was then dissolved in an organic solvent and then evaporated under a vacuum at a certain temperature. The complex is collected as a dry residue after being placed in a desiccator overnight.

Generally, there are two methods for the preparation of the pharmacophore.
