Liposomes Definition and background10 Liposomes were discovered in the early 1960’s and subsequently studied as cell membrane models. They have since gained recognition in the field of drug delivery. Liposomes are spherical vesicles which can be thought of as a hollow sphere they are composed of a bilayer membrane which entraps an aqueous core. The particle size of liposomes ranges from 20 nm to 10 μm in diameter. Liposomes vary in charge and in size depending on their manufacturing protocol

developed a process for creating small molecules that acted as selected agonists (activators) or antagonists (blockers) for specific purine receptors in the cell membrane. Purinex’s goal was to develop products that evoked a receptor-specific pharmacodynamic effect without producing undesirable outcomes that could result from interactions with other receptors. The company had 14 employees and maintained a chemistry laboratory a few miles from its main office. Purinex’s intellectual-property portfolio

hypoxanthine to xanthine to uric acid. At therapeutic concentrations it does not inhibit other enzymes involved in purine and pyrimidine synthesis. Its key pharmological action is that is reduces serum uric acid levels in the body. Uloric’s pharmacodynamic properties include a dose dependent decrease in 24-hour mean serum uric acid concentrations and an increase in 24-hour mean serum xanthine concentrations. In addition‚ it decreases daily urinary uric acid excretion and an increase in total daily
