Ferrous Gluconate is a form of mineral iron for oral administration, Ferrous Gluconate is absorbed in the stomach and small intestine and combines with apoferritin to form ferritin, which is stored in the liver, spleen, red bone marrow, and intestinal mucosa. Important in transport of oxygen by hemoglobin to the tissues, iron is also found in myoglobin, transferrin, and ferritin, and is as a component of many enzymes such as catalase, peroxidase, and cytochromes.

...Iron absorption tests were performed on 55 patients 3.2+/-2.0 years after isolated gastric bypass to identify those at higher risk for the late development of anemia. Twenty-nine of this group agreed to a therapeutic trial of iron /gluconate/ alone or with vitamin C over a 2-month period. All 55 patients were followed up for 27.1+/-1.0 months following the study. The iron absorption test identified patients with low iron stores, as indicated by low serum ferritin, and those with sufficient absorption surface to benefit from oral iron. The addition of vitamin C appears to enhance the therapeutic effect of iron by correcting ferritin deficits (P < 0.01) and anemia (P < 0.05). Differences in intestine length bypassed by the operation (10 vs. 100 cm) did not affect late ferritin and hemoglobin values.

...A study was... conducted on 40 women aged 20-35, with iron-deficiency anemia during or immediately after pregnancy all of whom presented Hb <10 gr/dL, Ht <33% and serum iron <60 ug/dL. All women with pregnancy-related pathological conditions, pre-existing on concomitant disease (Type I diabetes, heart diseases etc.) were excluded from the study. The women whose blood chemical parameters were largely homogeneous at the start of the study were divided into four treatment groups of 10 patients each and were treated as follows: Group A with oral liquid ferrous gluconate (75 mg per diem in 2 vials a day); Group B with solid ferrous gluconate (80 mg per diem in a single effervescent tablet); Group C with solid ferrous sulfate (105 mg per diem in a single tablet); and Group D with ferric protein succinylate (80 mg per diem in 2 vials a day). All were given iron treatment for 30 days. Treatment efficacy was analysed by comparing basal and final parameters using the T-test for paired dependent samples. The tolerance of the 4 treatment protocols was assessed by the analysis of any side effects such as nausea, vomiting, epigastric pain, diarrhea, constipation or other disorders reported by patients during treatment. Analysis of the therapeutic efficacy parameters (red blood cells, hemoglobin, hematocrit and serum iron) showed significant improvements but no statistically significant differences between the groups. However, the Group A patients treated with oral doses of liquid ferrous gluconate received a significantly lower cumulative dose of iron elements than the other groups: in detail 150 mg (p<0.05) less than Groups B and D; 900 mg (<0.001) less than Group C. By the end of treatment the Group A patients revealed significant increases versus basal values in red blood cells (p<0.001) 1,051,000 per cu mm or 33%, in Hb (p<0.001) 2.83 gr/dL or 32%, in Ht (p<0.001) 8.32% or 32%, in serum iron (p<0.05) 19.5 ug/dL or 61%. The same group also showed an increase in ferritin amounting to 7.8 ug/dL or 24% of the basal value. As to safety, only Group A patients reported no side effects and produced no drop-outs. Gastrointestinal and other aspecific side effects caused 1 drop-out each in Groups B and C and 2 drop-outs in Group D.

The effect of long-term oral iron supplementation on morbidity due to diarrhea, dysentery and respiratory infections in 349 children, aged 2-48 months, living in a poor community of Bangladesh, was evaluated in this double-blind study. The treatment group received 125 mg of ferrous gluconate (15 mg elemental iron) plus multivitamins and the controls received only multivitamins, daily for 15 months. House-to-house visits were made on alternate days by trained community health workers for recording symptoms and duration of illnesses and for monitoring medicine intake. Seventy-six percent of the children continued the syrup for over 1 yr. No untoward effects were noticed in either treatment group. The attack rates for diarrhea, dysentery and acute respiratory tract infections (ARI) were 3, 3 and 5 episodes per child per year, respectively. Each episode of diarrhea lasted a mean of 3 days, and those of dysentery and ARI, 5 days. The two treatment groups did not differ in the number of episodes, mean duration of each episode, or total days of illnesses due to diarrhea, dysentery and ARI. However, a 49% greater number of episodes of dysentery was observed with iron supplementation in a subset of the study children who were less than 12 months old (P=0.03).

5.4 Absorption, Distribution and Excretion

Absorption

The efficiency of absorption depends on the salt form, the amount administered, the dosing regimen and the size of iron stores. Subjects with normal iron stores absorb 10% to 35% of an iron dose. Those who are iron deficient may absorb up to 95% of an iron dose.


The iron bioavailability and acute oral toxicity in rats of a ferrous gluconate compound stabilized with glycine (SFG), designed for food fortification, was studied in this work by means of the prophylactic method and the Wilcoxon method, respectively. For the former studies, SFG was homogeneously added to a basal diet of low iron content, reaching a final iron concentration of 20.1 +/- 2.4 mg Fe/kg diet. A reference standard diet using ferrous sulfate as an iron-fortifying source (19.0 +/- 2.1 mg Fe/kg diet) and a control diet without iron additions (9.3 +/- 1.4 mg Fe/kg diet) were prepared in the laboratory in a similar way. These diets were administered to three different groups of weaning rats during 23 d as the only type of solid nourishment. The iron bioavailability of SFG was calculated as the relationship between the mass of iron incorporated into hemoglobin during the treatment and the total iron intake per animal. This parameter resulted in 36.6 +/- 6.2% for SFG, whereas a value of 35.4 +/- 8.0% was obtained for ferrous sulfate.

5.5 Mechanism of Action

Iron is necessary for the production of hemoglobin. Iron-deficiency can lead to decreased production of hemoglobin and a microcytic, hypochromic anemia.
