In a double-blind cross-over comparison of two mild analgesic compound tablets patients in moderate or severe pain showed a significant preference for the pentazocine-paracetamol compound tablet. Side effects were of a minor nature only and no patient dropped out of the trial because of them. It is concluded that significantly more patients (p <0.01) prefer the pentazocine-paracetamol compound to the dextropropoxyphene-paracetamol compound.

Butorphanol (1 mg and 2 mg) and meperidine (40 mg and 80 mg), given intravenously, were evaluated for analgesic efficacy and safety in a double-blind randomized study employing 200 consenting pre-partum patients in moderate to severe pain during the late first stage of labour. Both drugs provided adequate relief of pain to the mothers. There was no significant difference in the rate of cervical dilation, the foetal heart rate, the Apgar score, pain relief or neonatal neurobehavioural scores between those receiving butorphanol and those receiving meperidine. Twenty-two mothers who received butorphanol and eleven who received meperidine nursed their infants with no adverse effects observed. Side-effects were generally infrequent in this study; however, more side-effects were reported by the patients and observed by the investigator in the meperidine-treated cases (13%) than in the cases treated with butorphanol (2%).

A double-blind, randomized trial was conducted with 124 post-operative patients to compare the analgesic activity and possible side-effects of a new synthetic analgesic—butorphanol tartrate (1, 2, and 4 mg)—and pentazocine lactate (30 and 60 mg), administered intramuscularly. Butorphanol was determined to be 16 times more potent than pentazocine, on a weight basis. Both medications provided maximum pain relief within one hour after administration, and had comparable durations of action. Drowsiness was the most common side-effect, and it appeared to be dose-related in all test groups.

This study compared prazepam with diazepam, chlorazepate dipotassium, and placebo in the treatment of anxious out-patients. Patients were screened for participation in the study to be sure they met the criteria for inclusion. Patients were excluded if they had complicating physical or mental problems. All patients signed an informed consent. Seventy-three patients entered the study, thirteen did not complete at least two weeks of treatment and were not used in the data analysis. Of these thirteen, ten did not return and were lost to follow-up, two entered the hospital for reasons unrelated to the drug study, and one patient on diazepam was terminated because of increased anxiety. Sixty patients were used in the data analysis, thirty-six males and twenty-four females with an age range of 21–61 years. Side-effects were minimal. Drowsiness was reported by two people in the placebo group, one taking chlorazepate dipotassium, three on prazepam and one on diazepam. One diazepam patient reported nausea and vomiting. Scores on the Zung Self-Rating Scale for Anxiety showed all three drug groups to be superior to placebo. The Hopkins Symptom Check-list found prazepam and diazepam to be superior to placebo and chlorazepate. No differences among the groups were found in the Hamilton Anxiety Scale. Prazepam may offer advantages over the other available benzodiazepines since it may be more readily absorbed than chlorazepate and has less side-effects than diazepam.

The onset, quality and duration of analgesia and side-effects of a single bolus dose of either epidural pethidine 50 mg or fentanyl 100 mcg, administered immediately post-delivery, were compared in a randomised, double-blind study of fifty-five women undergoing epidural caesarean section. The onset of effect was more rapid with fentanyl, a significantly larger number of women achieving complete pain relief fifteen minutes post-administration (P<0.05). The quality of analgesia was good in both groups and the quality and duration of effective analgesia not significantly different. The incidence and severity of side-effects were low, with no significant difference between groups. One patient in the pethidine group experienced early onset respiratory depression; however, she did not require active treatment. Epidural fentanyl 100 mcg appears to offer a small clinical advantage over pethidine 50 mg for intraoperative use during caesarean section.

Double Blind Crossover Study

A double-blind crossover comparative study between carbuterol 3 mg thrice daily, carbuterol 2 mg thrice daily and salbutamol 4 mg thrice daily by the oral route was conducted in thirty patients suffering from bronchial asthma, selected at random, with more than 20% reduction in airway obstruction following isoprenaline inhalation. Each patient received all three drugs consecutively, each for 6 days, with a wash-out period in-between. The present study established a relative superiority of carbuterol 3 mg thrice daily over carbuterol 2 mg and salbutamol 4 mg thrice daily as evidenced by a higher percentage of subjective improvement (78.8%), preference shown by more cases (17/27), and need of additional drugs in a minimum number of cases (6/27), and significant improvement in FEV and MMEFR (p < 0.05). Salbutamol is known to produce tachycardia and a rise in blood pressure. There were no adverse side-effects on the cardiovascular system but unlike salbutamol, carbuterol produced a fall in pulse rate and blood pressure which should make carbuterol more acceptable to patients, especially on prolonged usage. There was an absence of significant side-effects on the haemopoietic system and kidneys; other side-effects observed with all three types of treatment were of a minor nature and did not necessitate withdrawal of the drug. Thus, carbuterol is an effective and safe selective beta-adrenergic stimulant, is relatively free from side-effects, and has a sustained bronchodilator effect, an advantage in therapeutic application, and is, as a result, a new effective drug in the management of bronchial asthma.

The first clinical experience with the new contrast medium, iohexol, in shoulder arthrography is reported. A double-blind comparison of iohexol and meglumine iothalamate, a conventional medium in standard use for arthrography, was carried out in a consecutive series of 60 adult patients forming two groups of 30 subjects each. No difference in the radiographic quality was seen immediately after contrast injection but in exposures at 20 min iohexol gave a significantly better arthrographic quality. Practically no adverse effects occurred during the examinations. Although minor side effects were numerous in both groups during the two days following arthrography, they were somewhat more frequent in patients given iothalamate

Thirty-nine patients suffering front arthrosis of the knee were randomly allocated to either pirprofen 400 mg b.i.d. or indomethacin 50 mg b.i.d., the treatment being double-blind. Assessments for pain and joint stiffness were made after 2 and 4 weeks. Both treatments appeared to be equally effective and induced side-effects in a limited number of patients. Similar observations were made in those patients who continued the treatment over longer periods of time.

Cardiovascular Stability

Butorphanol tartrate, a synthetic morphinan which has analgesic agonist and antagonist properties, was compared with meperidine for balanced anaesthesia. The two agents were found to be comparable in efficacy, maintenance of cardiovascular stability, and incidence of side-effects. Butorphanol has the advantage of being non-narcotic and having a lower propensity for addiction. Because of its antagonist properties, there appears to be a limit to its depressant effects on respiration.

And Behavior

Traditional clinical monitoring of children with epilepsy does not appear to be sufficiently sensitive to cognitive functioning and behavioral problems. Although subtle, these changes may alter a child's ability to perform well in school and in society. Physicians must prevent seizures without producing intolerable side effects, and ways of more appropriately assessing these side effects must be developed. In this double-blind, counter-balanced, crossover study of 21 children, the effects of phenobarbital and valproic acid on cognitive functioning and behavior were measured. There was no difference in seizure control between the drugs, and each medication was maintained in the therapeutic range for 6 months (mean phenobarbital level, 21.2 µg/mL; mean valproic acid level, 94.1 µg/mL). Children were treated with each drug for 6 months. Differences between the drugs were seen on measurements of cognitive function and behavior. On four tests of neuropsychologic function, children performed significantly less well while receiving phenobarbital (P &lt; .01). There was no evidence that the patients were sedated or less able to perform continuous performance tasks while receiving phenobarbital. Parental assessment of behavior indicated significantly worse behavior with the phenobarbital regimen for three items (P &lt; .01) and children were measureably more "hyperactive" (P &lt; .05). Routine clinical assessment of the patients did not reveal differences between the drugs with respect to routine laboratory measurements or side effects as assessed by history or physical examination. Although children may appear to tolerate a medication without clinically apparent problems, subtle but significant changes in intellectual function and behavior may be occurring. Additional, more sensitive, methods of monitoring patients while receiving these drugs is necessary.

Rate of recovery and incidence of complications were compared among three intravenous sedation techniques for colonoscopy. Sixty patients were randomized to receive diazepam and meperidine, midazolam and fentanyl, or propofol and fentanyl with a continuous infusion of propofol. Patients were sedated to a standard end-point using a double-blinded technique. There were no differences in rate of recovery or incidence of minor side effects among the three groups. The techniques were equally effective in providing sedation and analgesia for colonoscopy. All groups developed significant oxygen desaturation measured by continuous pulse oximetry. Over 20% of patients required supplemental oxygen due to persistent desaturation below 85% following administration of sedatives. The authors conclude that oxygen should be administered to all patients undergoing colonoscopy.
