In an open, comparative multicentre trial, 96 patients with arthritis of the large joints were treated with 75 mg diclofenac in one single dose in the morning, 50 mg diclofenac given twice daily, or 250 mg naproxen administered twice a day. It was noted that the length of history of pain was significantly longer in this naproxen group. Duration of the study was 14 days. Clinical parameters showed that the best degree of improvement was obtained with the diclofenac 50 mg twice-daily dosage regime. Diclofenac, in this study, showed better tolerability than naproxen.

A double-blind trial compared diclofenac with placebo in 44 outpatients. On from each group dropped out with dyspepsia, and one (placebo group) with ineffective treatment. Twenty completers received diclofenac. Dosage was one tablet (25 mg diclofenac) three times daily during the first week. In the second (final) week, most patients had four or six tablets. Diclofenac had significantly greater effect on pain, grip, morning stiffness, joint tenderness and swelling, and in comparison to previous treatments, even though the placebo group required significantly more rescue anaglesic. A few patients in each group had slight dyspepsia. One in the active and six in the placebo group complained of minor central nervous system symptoms. There were no serious side-effects. Haematological, biochemical and urinary analyses showed no clinically important changes. It is concluded that, in the short term, diclofenac (Voltarol) is effective in relieving the symptoms of inflammatory polyarthritis. It is well tolerated as placebo medication, and had no detrimental haematological or biochemical effects.

Analgesic response, incidental pain and pain mechanism were evaluated in order to predict the chances of pain relief in advanced cancer patients. In an observation period of about 2 months, 130 patients were followed at home until death using only a pharmacological approach to control pain according to the WHO ladders. Ninety-eight patients were considered. Pain relief was considered good if less than moderate. Pain was assessed during the course of examinations (2-3 a week) by independent observers. If other techniques were needed the result was considered negative. The patients were tested with an NSAID (Diclofenac) and assigned to group 1 if the pain became slight in 3 days. If the response was negative, a 4-day trial with opioids was started. If the pain was slight the patient was included in group 3, otherwise in group 5. Every patient belonging to these groups but with incidentical pain was included in groups 2, 4 and 6, respectively. For each group a subdivision was made according to the pain characteristics. There was a progressive worsening in pain relief in groups 4, 5 and 6, suggesting a good correlation between response to the drugs and future chances of pain control in a period of 2 months. This study demonstrates that incidental pain reduces the possibility of pain control (50%) with the exclusive administration of analgesics in patients with a mean life expectation of about 2 months. This negative influence is counterbalanced by the possible individual response to analgesics administered sequentially during a 1-week period (85.8% good pain relief with NSAID, 74% with opioids).(ABSTRACT TRUNCATED AT 250 WORDS)

Epidural morphine is used for postcesarean analgesia, and nonsteroidal antiinflammatory drugs are frequently administered to relieve uterine cramps after vaginal delivery. To assess the efficacy of a combination of low-dose epidural morphine and intramuscular diclofenac sodium in postcesarean analgesia, a double-blind, randomized study was conducted. Epidural anesthesia was given to 120 parturients who were randomly allocated into four treatment groups: group A received normal saline solution, 10 mL epidurally and 3 mL intramuscularly (IM); group B received 10 mL of epidural saline solution and 75 mg (3 mL) of diclofenac IM; group C received 2 mg of morphine in 10 mL of epidural saline solution and 3 mL of saline solution IM; and group D received 2 mg of morphine in 10 mL of epidural saline solution and 75 mg of diclofenac IM. Epidural injections were given after delivery of the placenta, and IM injections were given on arrival in the recovery room. Verbal analogue pain scores were recorded at 2, 4, 8, 12, 18, and 24 h after epidural injection. Subjective scores of overall pain relief were also recorded at 24 h. Results showed that scores of overall pain relief were significantly better in group D compared with group A, B, or C (P less than 0.05). Groups A and B required more supplemental meperidine than groups C and D. None of the subjects in group D requested supplemental analgesia. Compared with the other three groups, group D experienced a better analgesic effect for both wound pain and uterine cramping pain from 4 to 18 h (P less than 0.05). Incidence of nausea or vomiting, or both, and pruritus occurred more frequently in groups C and D compared with group A or B (P less than 0.05). No bradypnea was observed during the study period. Diclofenac alone was not effective in postcesarean analgesia.(ABSTRACT TRUNCATED AT 250 WORDS)

We have studied the efficacy of a continuous i.v. infusion of diclofenac 2 mg kg-1/24 h given for 2 days after major thoracic surgery in 30 patients in a double-blind, placebo-controlled, parallel-group design. The patients were able to obtain additional pain relief as on demand morphine boluses. In the diclofenac group, the consumption of morphine was reduced by 60% during the first and by 76% during the second day after operation compared with the control group. Overall, analgesia was also superior in the diclofenac group. Arterial oxygenation was significantly greater and the arterial PCO2 increased less during the first day after operation in the diclofenac group compared with the control group. Diclofenac had no significant effect compared with placebo on blood loss or on any bleeding or platelet test. Urine output was significantly less during the first day after operation in the diclofenac group compared with the control group, but was normal on the second day after operation; plasma creatinine concentrations were unchanged. I.v. diclofenac infusion combined with opioids delivered via a patient-controlled analgesia device seems a valuable method of pain relief after thoracic surgery in patients in whom more invasive techniques, such as extradural local anaesthetics and opioids, cannot be used. However, non-steroidal anti-inflammatory drugs should be used cautiously, if at all, in patients who are at risk of acute renal failure.

The pain response of mice to an injection of 0.5% formalin into the dorsal surface of a hindpaw is biphasic, with a first phase lasting for 5 min and a second phase lasting from 10 to 30 min post-injection. Intrathecal (i.t.) injection of [D-Pro2, D-Trp7,9]-substance P inhibited the first phase, and i.t. cysteamine inhibited the second phase. Lappaconitine (LA) and morphine (MOR) inhibited both phases equally in a dose-dependent manner. Diclofenac inhibited both phases, but the second phase was inhibited by lower doses. An i.t. injection of substance P (SP) or somatostatin (SOM) produced a characteristic behavioral response (scratching, biting, and licking). This behavioral response to SP and SOM was inhibited by s.c., intracerebroventricular (i.c.v.), or i.t. injection of MOR. In contrast, LA inhibited the SP- and SOM-induced response when injected s.c. or i.c.v., but had no effect when injected intrathecally. These results indicate that LA may act supraspinally to inhibit the transmission of nociceptive information by SP and/or SOM.

Diclofenac (Voltarol) as an adjunct to papaveretum for pain relief was examined by a prospective, randomized trial in 44 patients who had lateral thoracotomies. Patients given diclofenac, 75 mg intramuscularly twice daily, required less papaveretum in the first 3 days after operation (p less than 0.005) and had lower pain scores on a visual analog scale on all 5 postoperative days (p = 0.02 to less than 0.001); their respiratory vital capacity on the first postoperative day was also significantly higher (p less than 0.02). Diclofenac is a useful adjunct in the management of postthoracotomy pain.

A randomised, controlled study was undertaken to assess the postoperative pain and side effects experienced by patients undergoing day case diagnostic laparoscopy and laparoscopic sterilisation, and to evaluate the effectiveness in these patients of peroperative diclofenac. Patients undergoing laparoscopic sterilisation had significantly higher pain scores at one hour postoperatively, and at discharge, than patients undergoing diagnostic laparoscopy (p less than 0.01) but there were no significant differences in pain scores 24 hours after discharge. The incidence of postoperative side effects following discharge from hospital was high, but there were no significant differences between the groups. Diclofenac had no significant effect in either group on the severity of postoperative pain, or the incidence of postoperative side effects.

A wide variety of surgical and pharmacological methods have been described in an attempt to reduce pain after tonsillectomy, with conflicting results. Opiates are still widely used, despite unwanted side-effects. Recently the non-steroidal anti-inflammatory drugs have been shown to be effective against a variety of post-operative pains. Diclofenac is effective in both children and adults in the relief of pain after tonsillectomy when administered rectally, but absorption is variable, and suppositories are not widely accepted in the UK. The present double-blind study compared a single intramuscular dose of diclofenac with papaveretum in adults undergoing tonsillectomy. Post-operatively, the patients who received diclofenac had less pain and started drinking significantly sooner than the control group. There were no undesirable side-effects. Intramuscular diclofenac is superior to papaveretum in the relief of pain in adults undergoing tonsillectomy.

The known antiphlogistic in vitro effect of vitamin E was tested in a double-blind randomized study in patients with osteoarthritis. Fifty-three in-patients with osteoarthritis of the hip (n = 34) or the knee (n = 19) were treated for 3 weeks with 400 mg vitamin E (d-alpha-tocopherolacetate, V, n = 26) or 50 mg Diclofenac (D, n = 27) three times daily. A standardized therapeutic exercise program was performed; local therapy was not permitted. There were no significant differences in the efficacy of the two drugs, although one patient of the V-group refused further treatment after 8 days because of inefficacy. V reduced or abolished the pain at rest in 77% (D in 85%), the pain on pressure in 67% (D in 50%), and the pain on movement in 62% (D in 63%). Both treatments appeared to be equally effective in reducing the circumference of the knee joints (p = 0.001) and the walking time (p less than 0.001) and in increasing the joint mobility (p less than 0.002). Patients (n = 11) with a plasma-alpha-tocopherol increase higher than two standard deviations of the mean value at onset (greater than 25.2 mg/l) seemed to have a more pronounced reduction of pain (eight out of 11 patients) compared with four out of 11 patients with a moderate increase of vitamin E. Side effects occurred in two out of 26 patients with V (7.7%), and in 25.9% during D-treatment. One patient with D therefore stopped the therapy after 9 days.(ABSTRACT TRUNCATED AT 250 WORDS)
