Large-scale production of liposomes containing monomeric zinc phthalocyanine by controlled dilution of organic solvents.

U Isele et al.

Journal of pharmaceutical sciences, 83(11), 1608-1616 (1994-11-01)

This work describes the development of an organic solvent dilution method suitable for the large scale manufacturing of small unilamellar liposomes containing the water-insoluble photosensitizer zinc phthalocyanine in the monomeric state. N-Methyl pyrrolidone (NMP)/tert-butyl alcohol was selected as water miscible
