Method of producing a cationic liposomal preparation comprising a lipophilic compound

A cationic liposomal suspension having a pH of between about 3 and 7 and comprising at least one cationic lipid of at least 30 mol %, optionally at least one further amphiphile of up to about 69.9 mol %, a lipophilic active compound of at least 2 mol % and a stabilizing agent of about 0.1% (m/v) to about 20% (m/v), wherein said lipophilic active compound is physically and chemically stable for at least 12 hours at about 2 to 8° C., or at least 4 hours at ambient temperature.
