(1) The intramuscular neuroleptic of choice for the treatment of agitated schizophrenic patients and patients with acute mania is haloperidol, at a dose of 5 mg. Olanzapine is now marketed in France for hospital use in both these indications. (2) In two comparative trials in patients with schizophrenia, olanzapine 10 mg was shown to be no better than haloperidol 7.5 mg (a high dose). Control of agitation was satisfactory in three-quarters of patients after a single injection of either neuroleptic. (3) Olanzapine has not been compared with other neuroleptics in the treatment of acute mania. In one trial, olanzapine acted faster than lorazepam for injection (used at a rather low dose). (4) In one trial, patients given olanzapine had a lower incidence of acute dystonia and extrapyramidal symptoms (about 1%) than patients given haloperidol (about 6-7%), but the haloperidol dose (7.5 mg) was higher than recommended in the SPC (5 mg). The incidence of postural hypotension was significantly higher among patients given olanzapine (about 12%) compared with haloperidol (about 3%). (5) In practice, haloperidol remains the intramuscular neuroleptic of choice for the treatment of agitated patients with schizophrenia or acute mania.

The objective of this study was to obtain dehydrated liposomes using a novel procedure that involves freeze-drying (FD) of liposomes with TBA/water cosolvent systems. The effects of TBA on the integrity/stability of vesicles of HSPC (or SPC):Cholesterol (4:1) were investigated. TBA used as a cosolvent was detrimental to SPC liposomes, leading to increased particle size and leakage of trapped calcein. However, this was not the case for HSPC liposomes. The vesicle size and the retention of trapped calcein after lyophilization from cosolvents were similar to those after FD from water alone. Moreover, the addition of TBA can significantly enhance the sublimation of ice resulting in short FD cycles. The resulting lyophilized cake can form a loose powder upon agitation, which flowed well enough to be easily poured from the vial. Thus FD of HSPC liposomes using TBA/water cosolvent systems can provide sterile powder for specialized applications. In addition, in conjunction with a modified injection method, this FD technology might be used to produce dehydrated HSPC liposomes on a large scale.
