Liposomes containing lipophilic active ingredient are produced by dehydrating
a mixture of liposomes, lipophilic active ingredient and sugar, usually followed
by a rehydration step to form dehydration-rehydration vesicles. The lipophilic
drug is suitably paclitaxel. The sugar is usually sucrose. The liposome forming
compounds preferably include cholesterol and phosphatidylcholine, and optionally
an anionic lipid. The ratio of sugar:lipid is preferably at least 5:1 w/w. The
ratio of lipid:drug is preferably (up to 10):1 w/w.
