In a randomized, double-blind crossover study, 40 patients with postherpetic neuralgia were given single oral doses of clonidine, 0.2 mg, codeine, 120 mg, ibuprofen, 800 mg, or inert placebo. Pain relief and side effects were recorded for 6 hours. Patients reported significantly more relief after clonidine than after the other three treatments. Codeine and ibuprofen were ineffective. Sedation, dizziness, and other side effects were more frequent after clonidine (74%) or codeine (69%) than after placebo (36%) or ibuprofen (28%). Reported pain relief was greater during trials in which side effects were present. A single, mild side effect was associated with as much additional pain relief as multiple, severe side effects. Clonidine's superiority to codeine, which had a similar incidence of side effects, argues for a specific analgesic effect. In addition, side effects may have contributed to clonidine analgesia, perhaps by suggesting to patients that they had received a potent drug.

Somatization implies a tendency to experience and communicate psychological distress in the form of somatic symptoms and to seek medical help for them. So defined, it is neither a disorder nor a diagnostic category but a generic term for a set of experimental, cognitive, and behavioral characteristics of patients who complain of physical symptoms in the absence of relevant medical findings. Such patients are ubiquitous in all medical care settings, pose difficult diagnostic and management problems, and overutilize health care thus contributing to its cost. Somatization may be transient or persistent, and may or may not be associated with a diagnosable medical or psychiatric disorder. The most common concurrence of somatization is with affective and anxiety disorders, and, to a lesser degree, the somatoform disorders. Persistent somatization poses a serious clinical, social, and economic problem and hence early identification of potential chronic somatizers should be attempted to avoid its development. Pain, fatigue, dizziness, and dyspnea are the commonest symptoms. Etiology of somatization is multifactorial and so should be its management.

The efficacy and tolerance of 1200 mg/day oxaprozin and 100 mg/day diclofenac sodium were compared in 40 patients with ankylosing spondylitis in a 6-week open study. Overall improvement was seen in the patients in both treatment groups. Oxaprozin-treated patients showed significant improvement in spontaneous pain of the vertebral spine and in morning stiffness after 6 weeks' treatment. There were no statistically significant differences between the treatment groups. Therapy was discontinued in 10 patients; five treated with oxaprozin (three because of intolerance and two because of worsening of symptoms) and five taking diclofenac sodium (four because of intolerance and one because of worsening of symptoms). Five (25%) oxaprozin-treated patients and six (30%) diclofenac sodium-treated patients had side-effects, with gastro-intestinal disturbances and dizziness reported most frequently. There were no statistically significant differences between the groups in the frequency of side-effects. These results indicate that oxaprozin is a promising therapeutic agent for ankylosing spondylitis.

Voluntary abortions in day hospitals fulfill the need for shorter hospital stays and minimal interference with patient activities; on the other hand, it makes it more difficult to evaluate the possible complications of anesthesia. 1820 patients who received general anesthesia for voluntary abortion were given a questionnaire before they were discharged; items queried included drowsiness, headache, dizziness, nausea or vomiting, sore throat or mouth, abdominal cramps, pain at IV site, backache or muscular cramps, inability to perform daily activities. Only 465 patients returned the questionnaire. The most frequent complaint was sleepiness or drowsiness (19.8%), headache (7.1%), dizziness (15.1%), nausea or vomiting (8.2%), abdominal cramps (24.7%), and backache (16.7%). There seems to be less nausea or vomiting with the use of pentothal rather than alothane. Ketamine was never used on its own. The findings seen to suggest that the simplest combinations of drugs result in fewer and less severe complications than the use of several drugs.

The acute analgesic effect of single oral doses of 150 and 300 mg propyphenazone, 1000 mg acetylsalicylic acid (ASA) and placebo was investigated in 210 patients with pain following dental surgery. At most time points over the 3-hour observation period all the active medications had a significantly greater analgesic effect than placebo according to all the methods of pain assessment used. Both doses of propyphenazone reached their peak activity sooner than ASA, and their duration of action tended to be shorter. On a per milligram basis, the relative analgesic potency of propyphenazone was about twice that of ASA. All test substances were well tolerated. Side effects, such as tiredness, nausea, headache, dizziness etc., were reported by less than 20% of the patients. The nature of the adverse reactions was similar for all medications, and as they were recorded most frequently after placebo, they cannot therefore be definitely ascribed to one or the other of the active test substances.

Flurbiprofen (Ansaid, Upjohn), a substituted phenyl propionic acid, is a new analgesic/anti-inflammatory agent. To evaluate its relative efficacy in noninflammatory pain, 159 hospitalized women with moderate or severe postpartum uterine cramps were given single oral doses of 50 mg of flurbiprofen, 650 mg of aspirin, 60 or 120 mg of codeine sulfate, or placebo in a parallel, stratified, randomized block, placebo-controlled, double-blind trial. Patients rated pain intensity, pain relief, and side effects in uniform interviews for six hours after treatment. All measures of peak and summed analgesia exhibited significant differences among the five treatments. Flurbiprofen and aspirin showed the greatest analgesic response and were significantly superior to placebo. Results of codeine treatment were equivocal with no evidence of a positive dose response. Side effects were unremarkable except for dizziness and drowsiness after the 120-mg codeine dose. These findings suggest that flurbiprofen as an analgesic for patients with postpartum uterine pain is equivalent to aspirin and superior to codeine.

Twenty patients were treated with zidometacin by either the oral or the rectal route in a double-blind, short-term, balanced cross-over study, using the techniques of the double dummy. They suffered from osteoarthritis of the hip or knee or both. Zidometacin was administered at the daily doses of 400 mg p.o., and 600 mg by rectal route. The duration of each treatment was ten days. Zidometacin either as capsules or as suppositories showed a statistically significant influence on pain and functional indices even in this short-term evaluation. The side-effects reported by patients were three cases of dizziness and one case of nausea with capsules and one case of anal burning with suppositories, none of them requiring the interruption of the treatment.

The dihydroketo and dihydromonohydroxy analogues of carbamazepine (GP 47680 and GP 47779) were tested against carbamazepine for efficacy and tolerability in 13 patients (6 male and 7 female, mean age 69 years) and 11 patients (5 male and 6 female, mean age 64 years), respectively, all of whom were suffering from trigeminal neuralgia. Both derivatives brought about freedom from symptoms or a marked reduction in the pain in all patients. Onset of effect was observed within 48 h in most cases. For both analogues the effective dose was between 10 and 20 mg/kg body weight in most patients. There was a linear relationship, with a correlation coefficient of 0.83 (n = 36; p less than 0.001), between the doses and the serum level. Doses almost twice as high as those of carbamazepine are needed in order to achieve freedom from symptoms with the carbamazepine analogues. Since unwanted effects, in the form of dizziness and ataxia, occur much less frequently than with carbamazepine, the analogues can be administered in higher doses.

Interscalene brachial plexus block was performed on 40 patients for prophylactic pain relief after shoulder surgery. A dose of 1.25 mg/kg of 0.5% bupivacaine was injected for the block (Group 1) and continued with an infusion of 0.25% bupivacaine 0.25 mg/kg/h (Group 2). If the postoperative analgesia was insufficient, the patients received i.m. oxycodone 0.15 mg/kg. In Group 1, one patient managed without oxycodone supplementation during the 24-h observation period compared with eight patients in Group 2 (P less than 0.01). The rest of the patients received 3.8 +/- 1.6 doses (Group 1) and 2.5 +/- 1.2 doses (Group 2) of oxycodone (P less than 0.05). At 30 min, the mean bupivacaine plasma concentration was 1.0 microgram/ml in Group 1 and 0.9 microgram/ml in Group 2. The mean plasma level of bupivacaine increased from 0.7 microgram/ml after 180 min to 1.1 micrograms/ml (P less than 0.01) after 24 h of infusion, providing some evidence of accumulation during infusion. The dizziness and confusion experienced by three patients could be associated with the local anaesthetic, as they obtained relief after the infusion was stopped.

The efficacy, tolerance and acceptability of a single i.m. injection of 50 mg bromocriptine retard (in polylactic acid microspheres), given within 12 h after delivery for suppression of lactation, were investigated in 47 mothers not willing to breast-feed. Slight to moderate breast discomfort was noticed during the first postpartum days in 23% of the patients but lactation was indeed prevented in all cases and no rebound lactation occurred in any case. Only six patients exhibited at least two symptoms of mammary engorgement (congestion and pain or milk let-down): in this group, blood mean PRL levels were significantly less suppressed on postpartum days 2, 6, 21 and 28 (p less than 0.05 to p less than 0.001) than in the group of mothers completely free of any mammary symptoms. Slight side-effects (mostly dizziness), as mentioned at systematic request, were recorded in 34% of the patients; only 3 patients required treatment for their side-effects. Recovery of ovarian function was evident quite early (by day 28 in 72% of the patients), thus requiring early onset of contraception.
