A double-blind random study compared the effects of lorazepam and pantopon an intra-muscular premedication in healthy women for uterine curettage (D & C). Anxiety, as assessed by a self-rating test by the patient and by a trained observer, showed a significant reduction at one and one-half hours after lorazepam and a smaller reduction after pantopon, which was not significant. Sedation was satisfactory with no significant difference between the two drugs in the change before and after the premedication. Lorazepam showed much more amnesia than pantopon (p less than 0.001). The patients who had lorazepam required higher doses of thiopentone for the operation, and this, in part, led to longer intervals in recovery times after lorazepam. However, it is suggested that lorazepam itself was partly responsible for the longer recovery. Pantopon was followed by more nausea, vomiting and headaches, than lorazepam. The intra-muscular injection of lorazepam hurt more patients than did pantopon, but other local complications were negligible and comparable in both groups. The results of this study show that lorazepam produces better reduction of anxiety and much more amnesia than pantopon, with comparable sedation and much less nausea and vomiting. The only disadvantage of lorazepam is the lack of analgesia and, therefore, the need for more anaesthesia during the operation. The conclusion is that lorazepam is a very satisfactory premedication and warrants more use as such.

Lorazepam 2.5 mg was compared with promethazine 50 mg as oral premedication in a double-blind study in women. The premedication was given at the same time to all patients on each operating list, and both drugs continued to be effective 6 h after ingestion. A similar number of patients considered each drug to have relieved anxiety and the amnesic effect of lorazepam was confirmed. However, the use of lorazepam alone was accompanied by significantly more salivation during and after anaesthesia than the use of promethazine, especially in patients in whom the trachea was intubated. There was also a higher frequency of vomiting during and after operation with lorazepam (seven of 67 patients) than after promethazine (one of 71 patients). Promethazine produced dyskinetic side-effects in six of 71 patients.

The high incidence of postoperative emesis after strabismus surgery in pediatric outpatients can be reduced by the prophylactic administration of droperidol 75 micrograms/kg intravenously. However, this may be associated with profound sedation, delayed discharge, dysphoria, agitation, and extrapyramidal symptoms in this population. Because lorazepam used as an antiemetic in children during chemotherapy decreased the incidence of nausea and vomiting, we compared the antiemetic effects of lorazepam and droperidol in a randomized, double-blind, placebo-controlled study of 129 healthy children undergoing surgical correction of strabismus. The children, aged 1-13 yr, were randomly allocated into three groups. The children in group 1 received droperidol 75 micrograms/kg intravenously; those in group 2 received lorazepam 10 micrograms/kg intravenously; and those in group 3 received placebo. Anesthesia consisted of halothane, nitrous oxide in oxygen, and atracurium. Study drugs were administered intravenously after induction of anesthesia but before surgery. In children 3-13 yr old, administration of either lorazepam or droperidol was associated with a lower (P < 0.024) incidence of postoperative vomiting. There was no difference between the antiemetic effect of lorazepam and that of droperidol. The incidence of postoperative agitation was greater in the droperidol group (P < 0.001) than in the lorazepam and placebo groups. Postdischarge vomiting was less (P < 0.009) in children younger than 3 yr of age. Lorazepam, similar to droperidol, has an antiemetic effect in outpatient children 3-13 yr old undergoing strabismus correction, but it is associated with less postoperative agitation than is droperidol.

Lorazepam, dexamethasone and high-dose metoclopramide were given to 54 patients to prevent emesis induced by cisplatin (50-120 mg/m2) on day 1, while prochlorperazine and dexamethasone were administered on days 2 and 3 for control of delayed emesis. Nausea and emesis were recorded from day 1 to day 8. This combination was well tolerated. Prevention on day 1 was complete for 72% of patients and satisfactory (less than or equal to 2 emeses on day 1) in 85%. From days 2 to 8, no emesis, less than or equal to 2 and greater than 2 episodes occurred in 70, 11 and 19%, respectively. Overall control (days 1-8) was complete in 55.5% and satisfactory (less than or equal to 2 emeses on day 1 and/or less than or equal to 2 emeses from days 2 to 8) in 74%. Delayed emesis started on days 2-5. Mean duration was 2.6 days. Delayed nausea or emesis were more frequent when emesis occurred on day 1. Based on data previously reported and on these observations, better ways to prevent delayed events are discussed. Further trials must record systematically delayed side effects.

Results of a randomized trial on antiemesis for cisplatin (CDDP) and non-CDDP chemotherapy-induced vomiting are reported. One hundred and sixty-three outpatients received 282 chemotherapy courses (141 with CDDP and 141 without CDDP). Patients were randomly assigned to receive either high-dose metoclopramide plus methylprednisolone (arm A) or the same drugs plus lorazepam (arm B). In both arms a high protection rate for vomiting was obtained, on the whole without statistically significant differences. Patients who received lorazepam had, however, significantly fewer nausea episodes during first day post-chemotherapy (p less than 0.05). Arm B was also superior in anxiety control during the first day of chemotherapy (p less than 0.01). Both regimens were significantly more effective in patients who had not been given chemotherapy previously (p less than 0.01). No differences in antiemetic protection were found between CDDP and non-CDDP courses. No significant differences were found in premonitory vomiting control between the two arms of the trial. Toxicity was very mild with both regimens, although sedation was significantly higher in arm B (p less than 0.001). We conclude that high-dose metoclopramide plus methylprednisolone is a highly effective combination for chemotherapy-induced nausea and vomiting, and that it is quite suitable for outpatient use. Lorazepam did not significantly increase the antiemetic potency of the combination, nor did it improve premonitory vomiting control, although it gave a better control of acute nausea and anxiety.

High dose metoclopramide is an effective anti-emetic for use with cisplatin containing chemotherapy regimens but can cause extrapyramidal reactions. Lorazepam and dexamethasone are increasingly being used to alleviate chemotherapy induced emesis. This trial has assessed the contribution of high dose metoclopramide to anti-emetic control when given with dexamethasone and lorazepam. Eight-one patients receiving chemotherapy, mainly for gynaecological malignancy, entered a randomised double blind cross-over trial comparing dexamethasone and lorazepam with or without a 24 h metoclopramide infusion. This was followed by oral dexamethasone with or without oral metoclopramide for three further days depending on the initial randomisation. Sixty-one patients were fully evaluable. Fifty-five received cisplatin containing regimens and six non-cisplatin regimens. There was a significant reduction in the number of episodes of vomiting during the first 24 h in patients receiving the metoclopramide combination (P = 0.0001). On first exposure to chemotherapy 45% of patients receiving dexamethasone, lorazepam and high dose metoclopramide had no vomiting while 67% had two episodes or less ('major control'). This compared to 11% total control and 25% major control in those receiving dexamethasone, lorazepam and placebo. The control of nausea in the first 24 h was also improved (P = 0.0001). There was no difference in the degree of nausea or vomiting during the following three weeks between those receiving oral dexamethasone alone and those receiving dexamethasone and metoclopramide. Both groups showed a significant increase in nausea in the three weeks following the second course of treatment when compared to the first (P = 0.0007). Extrapyramidal reactions were recorded in 11.5% of patients receiving metoclopramide. More patients stated a preference for the metoclopramide combination although this was not statistically significant (chi 2(1) = 0.29, P = 0.59). In conclusion the combination of dexamethasone and lorazepam can give major control of emesis in 25% of patients receiving very emetogenic chemotherapy. The addition of metoclopramide increases this to 67% on first exposure to chemotherapy, but at the expense of extrapyramidal reactions in 11.5%.

Lorazepam, oxazepam, and methylprednisolone were compared for antiemetic efficacy in patients receiving cisplatin chemotherapy. Three consecutive courses of cisplatin-containing chemotherapy were administered at equal doses so that each patient acted as his own control. Of 100 patients randomized, 85 received at least two of the three agents and were evaluable for analysis. Lorazepam significantly reduced the number of patients with more than ten vomits compared to either oxazepam (P less than 0.05) or methylprednisolone (P less than 0.001). Lorazepam also significantly reduced the number of patients with the most severe degrees of vomiting compared to either oxazepam or methylprednisolone (both P less than 0.005). The duration of vomiting was reduced significantly after the first 48 hours postchemotherapy for those patients receiving lorazepam over those receiving methylprednisolone (P less than 0.05). Lorazepam significantly reduced the number of patients with severe nausea compared to both oxazepam and methylprednisolone (both P less than 0.05), but there were no significant differences in duration of nausea among the groups. The results of linear analogue self-assessment scores indicated a strong patient preference for lorazepam over both oxazepam and methylprednisolone. Drowsiness was significantly more common with both lorazepam and oxazepam compared to methylprednisolone (both P less than 0.001). Patients who received lorazepam or oxazepam also experienced significantly more severe drowsiness than those patients receiving methylprednisolone (both P less than 0.001). Lack of recall was significantly more common with lorazepam than with oxazepam and methylprednisolone (both P less than 0.001) and was more profound when lorazepam was compared with oxazepam (P less than 0.05) and with methylprednisolone (P less than 0.001). Methylprednisolone was administered with minimal side effects. The results of this randomized cross-over study indicate that, in the dosage/schedule used, lorazepam is a significantly superior premedicant than is either oxazepam or methylprednisolone in alleviating the distress of cytotoxic-induced emesis in patients receiving cisplatin-containing chemotherapy.

The influence of fluid intake and hydration rate on the frequency of vomiting was evaluated during 254 outpatient cisplatin infusions administered to 60 patients. The basic antiemetic regimen was consistent and used metoclopramide hydrochloride (Reglan) 2 mg/kg/dose (means = 150 mg) starting 30 minutes before cisplatin for a total of three doses; dexamethasone (Decadron) mean - 15 mg - and lorazepam (Ativan) 1 mg intravenous bolus before cisplatin, along with thiethlperazine maleate (Torecan) given routinely throughout the treatment beginning the evening before. Only 20% (38/192) of patients experienced symptoms of vomiting when hydrated at a rate of greater than 333 cc/hour as opposed to 44% (27/62) patients hydrated at a rate of 300 cc/hour or less (p = 0.01). Patients whose oral intake ranged from 400 cc to 1000 cc experienced noticeably less vomiting (14%) than patients who either refused fluids (39%, p = 0.001) or exceeded 1000 cc oral intake (36%, p less than 0.05) during treatment. Manipulation of total fluid intake (IV plus oral), although not statistically significant, seemed to affect the incidence of vomiting. By maintaining a positive intake/output ratio greater than 1, patients were able to decrease their vomiting episodes. Patients who gained weight during the treatment experienced significantly fewer episodes of vomiting (29%) than those who either lost or maintained their weight (71%). Findings suggest that manipulating both oral and IV fluid intake as well as the IV fluid rate may reduce symptoms of vomiting in the outpatient cisplatin setting.

Combinations of metoclopramide and dexamethasone given intravenously control vomiting caused by high doses of cisplatin. Lorazepam and diphenhydramine are useful adjuncts to antiemetics. In a double-blind trial, 120 patients receiving high-dose cisplatin (120 mg/m2) for the first time were randomly assigned to receive either lorazepam (1.5 mg/m2) or diphenhydramine (50 mg) intravenously, 45 minutes prior to cisplatin. In addition, all patients received intravenous dexamethasone (20 mg) 40 minutes prior to chemotherapy along with metoclopramide (3 mg/kg) 30 minutes before and 90 minutes after cisplatin. Patients were directly observed in the hospital after cisplatin administration and completed a subjective assessment questionnaire. Overall, 60% of patients experienced no vomiting, and 83% had two or fewer emetic episodes during the study. There were no significant differences in objective antiemetic control between the two regimens. Only 3% of patients receiving lorazepam experienced treatment-related restlessness as opposed to 19% given diphenhydramine (P = 0.007). Less recall of chemotherapy administration (P less than 0.001), more sedation (P = 0.003), and transient enuresis while sedated (P = 0.0002) were characteristic of patients receiving lorazepam. Patient-generated ratings revealed less anxiety (P = 0.0001) for those individuals given the lorazepam-containing combination. Both regimens were well accepted, with 89% of patients receiving the lorazepam combination and 83% of those given the diphenhydramine regimen wishing to receive the same drugs in the future. Some degree of delayed vomiting occurred in 85% of patients during the 4-day period following this study. During the time that patients are at the greatest risk for emesis, the 24 hours immediately following cisplatin, three drug antiemetic combinations of either lorazepam or diphenhydramine with metoclopramide plus dexamethasone stopped cisplatin-induced emesis for the majority of patients and lessen other treatment-related side effects. Less restlessness and anxiety were observed among individuals receiving the lorazepam-containing combination.

There currently is no pharmacologic approach to the problem of anticipatory nausea and vomiting (ANV). Lorazepam (Ativan, Wyeth Laboratories, Philadelphia) is an interesting candidate drug if it could block the recall of the unpleasant events associated with chemotherapy, especially if it also has antiemetic properties. Since ANV is a conditioned (learned) response, it may well depend on a memory imprint of the stimulus. This pilot study was designed to use intravenous lorazepam given before and after cisplatin infusion in 32 patients, and to make detailed measurements of nausea, vomiting, recent memory, anxiety, and sedation as well as toxicity. Satisfactory responses occurred in about 70%, as rated separately both by investigator and patient. Forty-six percent did not even recall receiving chemotherapy, regardless of whether or not they vomited; 80% had no significant anxiety after chemotherapy. Adverse reactions included some cases of perceptual disturbance, urinary incontinence, diarrhea, hypotension, and one case of severe transient amnesia. No long-term adverse effects were noted.
