Ferrous gluconate 300mg/5ml oral solution

BackgroundPatients with a low serum blood hemoglobin concentration suffer from a pathologic state that contributes significantly to morbidity and mortality figures worldwide. Oral iron supplementation, the most common method of treatment, is reported to have poor patient adherence, due to its unwanted side effects. Lactoferrin is a globular glycoprotein of the transferrin family that has shown promising results in patients with a low hemoglobin profile. This systematic review and meta-analysis of randomized clinical trials explore its effect on blood hemoglobin compared to conventional iron preparations.MethodsWe followed the PRISMA Guidelines for reporting systematic reviews and meta-analyses. A systematic search was conducted in electronic databases (PubMed, CINAHL, Scopus, and Cochrane) from inception to June 2022. Meta-analysis was performed on studies where the primary outcome was the mean Hb concentration, comparing lactoferrin to ferrous sulfate subgroups. We assessed the methodological quality of the trials using the Jadad scoring scale.ResultsNineteen trials published between 2006 and 2022 met the eligibility criteria. It has been found that the levels of Hb concentration in different populations with varying health conditions undergo a moderate to significant change after treatment with all types of trialed interventions, including both iron and lactoferrin treatment, in both the intervention group and the comparison group. Most of the studies report that LF showed a statistically significant increase in Hb concentration levels, compared to those in the iron group. The meta-analysis included seven trials comparing the effectiveness of lactoferrin to ferrous sulfate for patients with low Hb concentration. The analysis showed a statistically significant increase in Hb levels in the oral bovine lactoferrin group compared to ferrous sulfate (SMD -0.81, 95% CI: -1.21, -0.42, p 2 = 95.8%, P heterogeneity ConclusionsLactoferrin is an effective intervention at doses of 100-250 ng/day, for patients with a low Hb concentration. As a safer option and with high compliance evidence, lactoferrin can serve as an iron replacement treatment for patients who may be experiencing adverse side effects due to iron intake.

Background/Objectives: Iron deficiency (ID) is the most common nutritional disorder in childhood worldwide. It has profound consequences for growth, neurodevelopment, behaviour, and overall health. Despite the long-standing efficacy of oral ferrous salts, their poor gastrointestinal tolerability and adherence challenges have spurred the development of alternative formulations and innovative dosing strategies. Methods: We conducted a narrative review of national and international guidelines, pediatric randomized controlled trials, observational and cohort studies, cost-effectiveness analyses, diagnostic method papers, and reviews, with emphasis on diagnostic innovations, therapeutic outcomes, tolerability, and formulation-specific efficacy. Results: Ferrous salts remain the gold standard for efficacy, low cost, and guideline endorsement, but up to 40% of children experience GI intolerance. Therefore, a lower dosage of ferrous salts has been proposed for IDA as still being an efficacious and better-tolerated schedule. Also, alternate-day dosing improves absorption and tolerability and is supported by a recent pediatric RCT. Newer formulations-ferric polymaltose, ferrous bisglycinate, co-processed bisglycinate with alginate (Feralgine™), and vesicular encapsulated forms such as sucrosomial and liposomal ferric pyrophosphate-showed improved tolerability and palatability, supporting adherence with hematologic outcomes comparable to ferrous salts, particularly in children with intolerance, malabsorption, or inflammatory comorbidities. Intravenous iron is effective and safe with modern preparations and is reserved for severe anemia, malabsorption, or oral therapy failure. Conclusions: Oral ferrous salts should remain the first-line therapy in pediatric ID/IDA. Future pediatric trials should prioritize head-to-head comparisons of formulations, hepcidin-guided dosing, and patient-centred outcomes, including neurocognitive trajectories and quality of life.

Iron-deficiency anemia and pre-anemic iron deficiency are the most frequent pathologies. The first line of treatment involves oral iron supplementation. The simplest, least expensive, and most commonly prescribed drug is ferrous sulfate, while other ferrous salts and ferric complexes with polysaccharides or succinylated milk proteins are also widely used. In recent years, novel iron formulations have been developed, such as the lipophilic iron donor ferric maltol, or nanoparticle encapsulated sucrosomial® iron. Oral iron supplementation is usually efficacious in correcting iron-deficiency anemia and replenishing iron stores but causes gastrointestinal side effects that reduce compliance. When oral iron supplementation is contraindicated, intravenous iron therapy can rapidly achieve therapeutic targets without gastrointestinal complications. Herein, we critically review literature on relative efficacy and tolerability of currently available oral iron supplements, and summarize recent data on optimal dosage and frequency.
