Information about a favorable prognosis for a patient, recommendations for activities, and optimal pharmacotherapy are a mainstay in the effective treatment of acute nonspecific low back pain (NLBP). Standard pharmacotherapy for acute NLBP includes nonsteroidal anti-inflam-matory drugs (NSAIDs). However, the longer their administration and larger doses, the higher the risk of side effects are. NSAIDs are contraindicated in some cases. In this connection, it has become necessary to search for new opportunities for the pharmacotherapy of acute NLBP. The results of experimental studies have demonstrated the analgesic and anti-inflammatory effects of high-dose B vitamins. Clinical trials have confirmed the efficacy of Vitamin B complex (thiamine, pyridoxine, and cyanocoba lamin) in the treatment of acute NLBP. The paper considers the practical significance of concomitant administration ofB vitamins and NSAIDs in NLBP and notes the efficacy of milgamma used both alone and in combination with NSAIDs in the treatment of acute NLBP.

Vitamin B12 (B-12) deficiency is still relatively common in low-, medium-, and high-income countries, mainly because of dietary inadequacy and, to a lesser extent, malabsorption. This narrative review is based on a systematic search of evidence on methods to assess B-12 bioavailability and technologies to enhance its absorption. A total of 2523 scientific articles identified in PubMed and 1572 patents identified in Orbit Intelligence were prescreened. Among the reviewed methods, Schilling's test and/or its food-based version (using cobalamin-labeled egg yolk) were used for decades but have been discontinued, largely because they required radioactive cobalt. The qualitative CobaSorb test, based on changes in circulating holo-transcobalamin before and after B-12 administration, and the14C-labeled B-12 test for quantitative measurement of absorption of a low-dose radioactive tracer are currently the best available methods. Various forms of B-12 co-formulated with chemical enhancers (ie, salcaprozate sodium, 8-amino caprylate) or supplied via biotechnological methods (ie, microbiological techniques, plant cells expressing cobalamin binding proteins), encapsulation techniques (ie, emulsions, use of chitosan particles), and alternative routes of administration (ie, intranasal, transdermal administration) were identified as potential technologies to enhance B-12 absorption in humans. However, in most cases the evidence of absorption enhancement is limited.
