Randomized Controlled Trial Comparative Study Clinical Trial[Reduced diclofenac administration by B vitamins: results of a randomized double-blind study with reduced daily doses of diclofenac (75 mg diclofenac versus 75 mg diclofenac plus B vitamins) in acute lumbar vertebral syndromes].
Pain syndromes of the lumbar spine are one of the main problems in orthopedic practice. The therapeutic effect of NSAIDs is not subject to doubt in this connection. But considering that the application of NSAIDs is frequently associated with side effects, a reduction of dosage would be to the patient's benefit. ⋯ There was the option to terminate therapy in the trial after 3-4 days in the case of total pain relief. 45 patients could stop the treatment due to remission of symptoms. 30 patients belonged to the combination therapy group, the other 15 took diclofenac alone; this difference is statistically significant (p less than 0.05). All parameters concerning pain relief and movement of the vertebral column showed statistically significant differences in favour of the B-vitamin-diclofenac-combination, too. The results document the positive influence of B-vitamins on painful vertebral syndromes and indicate that B-vitamins contribute to saving of NSAIDs by shortening the treatment time and reducing daily NSAID-dosage.

Review[The interactions of vitamins B1, B6 and B12 with non-steroidal antirheumatic and analgesic drugs: animal experiment results].
B-vitamins are therapeutically used in combination with nonsteroidal antiinflammatory drugs and weak analgesics. The animal experiments dealing with the antinociceptive and antiinflammatory activity of such combinations are reviewed with reference to the significance of the single vitamins B1, B6, and B12, the possible mechanisms of action, and the relevance of the animal data to man.

Comparative StudyAcute effects of vitamin B6 and fixed combinations of vitamin B1, B6 and B12 on nociceptive activity evoked in the rat thalamus: dose-response relationship and combinations with morphine and paracetamol.
Nociceptive activity was elicited in neurones of the thalamus by supramaximal electrical stimulation of afferent C fibres in the sural nerve of rats under urethane anesthesia. The fixed combination of vitamin B1, B6, and B12 (Neurobion) as well as of vitamin B6 administered by i.p. injection dose-dependently reduced the evoked nociceptive activity. The ED50 of Neurobion is 4.6 ml/kg (at 100 min after injection) and that of vitamin B6 is 189 mg/kg (at 90 min after injection). ⋯ It is concluded that the antinociceptive effect caused by a single injection of Neurobion is largely due to vitamin B6. Vitamin B12 may contribute to this effect, whereas vitamin B1 alone exhibited only a slight effect on nociception. Moreover, it appears that Neurobion produces its antinociceptive effect after a single injection and after repeated administration during several days by different mechanisms so that the effect of analgesic agents is not enhanced following a single injection of Neurobion but may be enhanced after repeated administration of the compound.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial[Results of a double-blind study of diclofenac + vitamin B1, B6, B12 versus diclofenac in patients with acute pain of the lumbar vertebrae. A multicenter study].
Several clinical trials have shown that the duration of treatment of painful vertebral syndromes can be shortened by using a combination of vitamins B1, B6, B12 and diclofenac instead of diclofenac. In addition, a more efficient pain relief could be achieved by the combination therapy. In order to confirm these results, we compared the clinical efficacy of diclofenac (25 mg) and a combination preparation with diclofenac (25 mg) plus vitamins B1 (thiamine nitrate 50 mg), B6 (pyridoxine hydrochloride 50 mg) and B12 (cyanocobalamin 0.25 mg) in a multicentric randomized double-blind study including 418 patients. ⋯ The differences in favour of the B-vitamin-diclofenac-combination were statistically significant in patients with severe pain at the beginning of therapy. Considering undesirable side-effects (symptoms in 70 out of 418 patients) there were no significant differences between the two medications. This clinical trial provides further evidence that the combination therapy with diclofenac plus B-vitamins is more effective than diclofenac alone for the treatment of painful vertebral syndromes.

[Comparative effect of oral fat loads with saturated, omega-6 and omega-3 fatty acids before and after fish oil capsule therapy in healthy probands].
To evaluate digestion, absorption and postprandial lipemia of diverse fats before and after fish oil capsule therapy (with ethylester) 20 healthy volunteers were recruited. A significant increase (p less than 0.001) in fecal fat excretion after fish oil capsule therapy, as well as serious diarrhoea after fat loads with 100 g of fish oil was noted. It was found, that under fish oil fat loads the total triglyceride content of the mucosa was significantly (p less than 0.001) lower compared to butter fat loads. Decrease digestion and absorption of omega-3 fatty acids was postulated.
