Definitions
- the present invention relates to the field of public health and in particular to a preparation containing ionic iron and heminic iron in the form of powders to be used orally in the form of tablets or in aqueous suspension for the prophylaxis and treatment of lack of iron.
- the ionic iron content comes from a ferrous salt and the heme iron from a powdered blood product that is obtained from blood and other natural products. Iron is an essential mineral for life although the daily requirements are low of about 1 mg per 70 kg of weight.
- the human organism supplies its needs partly by the endogenous iron that derives from the destruction of the aged red blood cells and partly by the iron supplied through food.
- the ionic iron contained in foods of plant origin has to be reduced to bivalent iron by gastric juice and then absorbed in the duodenum and first part of the jejunum thanks to the favorable effect of pH in the first portion of the small intestine and stored above all in the liver
- ferrous or ferric iron salts The effects of the administration of ferrous or ferric iron salts is revealed in the gastrointestinal tract by damage to the mucous membrane such as perforation and necrosis, allergic reactions such as tachycardia and in some cases anaphylactic chock and cardiocirculatory collapse observed after of intramuscular administration (ferrodextran) and intravenous route (ferrodextrin).
- ferrodextran intramuscular administration
- ferrodextrin intravenous route
- ferrous salt has not been devoid of its adverse effects and low efficacy ⁇ Treatment of anemia with microencapsulet ferrous fumarate plus ascorbic acid supplied as sprinkles to complementary (weaning) foods. 2001. Stanley Zlotkin, Paul Arthur, Kojo Yeboah Antwi and George Yeung. AJCN, VoI. 74, No. 6, 791-795 ⁇ determined in the first place by the low bioavailability that forces the use of high doses that accentuate its astringency and irritability to the intestinal mucosa cause abdominal pain, constipation, diarrhea, nausea, vomiting and general disorders whose severity will depend on the dose consumed and the time of therapy. As an alternative to the use of synthetic salts, the use of iron of natural origin has been of scientific interest.
- Ferritin is extracted from the bovine and equine spleen, it is water soluble and therefore administrable orally, it has no undesirable effects on the digestive tract and also constitutes an iron reserve that is not activated by intracellular proteins.
- heminic iron Ferroprotoporphyrin or hemoglobin prosthetic group
- the objective of the present invention is to develop a preparation containing heminic iron and ionic iron that simultaneously uses the two enterocyte receptors without the risk of saturation block which results in superior prophylaxis and deficiency treatment results. of iron, without adverse reactions and obtaining other beneficial responses by the content of amino acids, folic acid and ascorbic acid with a more reliable quantification of iron content.
- the novelty of the invention is that a unique product was obtained that does not exist in the market, which is not described above and that is distinguished by containing heminic iron, ionic iron, amino acids, folic acid and ascorbic acid and has the following characteristics:
- the ionic iron content represents a maximum of 70% of the total iron.
- the new product increases the solubility of ferrous fumarate, which eliminates the unpleasant effects of this product when it is supplied only in suspension, which can cause deposition in the teeth and the appearance of a dark color.
- the total content of amino acids in concentrations of 20 to 30 ⁇ mol / 100 ⁇ L of proteins contributes not only to combat anemia, but also to exert a favorable effect of iron absorption, contributes to its better biological use since it allows the synthesis of proteins that are part of the structure of hemoglobin and exerts a restorative effect in hypercatabolic states as cancerous patients in which a vital aspect is to improve the quality of life.
- the dehydrated based on heminic iron, the salt of ferrous fumarate, ascorbic acid and folic acid were mixed and homogenized in homogenizers of 5 Kg in the proportions that would guarantee ionic iron concentrations of 30 to 70% of the total iron and 30 to 70% heminic iron.
- iron per gram of powders Based on this, the final proportions were 6 to 26% of the ferrous salt and 74 to 94% of the blood product provided by the heminic iron.
- the new product was dispensed in 235 mL bottles containing 15 grams for an iron concentration between 11 and 22 mg / mL.
- the trial included 42 children aged 6 to 9 years, 24 of them without anemia who received a prophylactic dose of 15 mg daily for 2 months and 18 with anemia who received a daily dose of 6 mg per kg of live weight until recovery. clinical or two months maximum treatment.
- the hematological analyzes performed were Hemoglobin by the method of cyanometahemoglobin and Hematocrit by means of capillaries or microhematocrit before starting treatment one month and two months respectively.
- individual behavior was monitored to evaluate other clinical indicators and the occurrence of adverse reactions. The following result was provided.
- Indirect compression consists in adding to the active substances other substances that allow compressing the powder and obtaining the tablet. This procedure allowed to obtain tablets of a mass between 500 and 700 mg with an iron concentration between 11 and 30 mg per tablet and complying with all technological specifications.
- Neoplastic patients with anemia were administered 30 to 45 mL of the suspension daily 2-3 times a day 15-20 minutes before meals for six months.
- Oncospecific treatment based on cytostatics or radiation was maintained as appropriate.
- Systematic control of hematological parameters and immunological profile was maintained.
- Neoplastic patients without anemia were divided into two groups; One was given the product prophylactically at a dose of 15-30 mL daily once or twice a day 15-20 minutes before meals for 6 months and another group was as a control. As main recovery criteria, the evolution of hemoglobin and the continuity of oncospecific treatment were taken into account. The results obtained were the following:
- Hemoglobin increased from 94 g / L to 129 g / L at 90 days, remaining without significant differences until 180 days after treatment.
- hemoglobin was 35 g / L at 60 days, allowing oncospecific treatments to be initiated and followed in these patients.
- the increase in platelets and leukocyte count constituted an important result, as these cells indicate defense mechanisms and corresponded to the immunological results of delayed hypersensitivity.
- the determination of iron was carried out by the method of the PHILIPS ANALYTICAL ATOMIC ABSORPTION applying the technique of Determination of trace metals in food by atomic absorption spectroscopy.
- the preparation has 11-22 mg of iron per mL in 10% aqueous suspension and 11 to 33 mg per tablet of 500 to 700 mg of mass.
- the amino acid determination was performed on an LKB amino acid analyzer with total hydrolysis of the sample using 2 mL of the sample and applying 10 ⁇ L. The concentration was 20 to 30 ⁇ mol / 100 ⁇ L of proteins.
- the new product obtained bases its effectiveness on the impact to combat the most widespread deficiency disorder that is iron deficiency and for which it requires easy-to-use presentation forms such as restoring powders, tablets and granules.
- Osmometry The temperature variation of freezing is proportional to the concentration of a substance and in turn this measure is proportional to the amount of dissolved ions. When the samples have a concentration of particles such that they cannot be read, it is necessary to dilute in order to perform the reading.
- the samples of powders plus sodium fumarate have a reddish color and a homogeneous appearance, while the samples of powders plus ferrous sulfate have a light Carmelite coloration and do not dissolve completely. and
- the salt of choice is ferrous fumarate.
- ferrous fumarate ionic iron must represent between 30 and 50% of the total iron.
- ferrous sulfate is more soluble in water than ferrous fumarate, it is not possible to use it as a source of ionic iron due to changes in the characteristics of the new product obtained and because the use of osmometry is not feasible to evaluate the solubility behavior since its values decrease over time, so at 30 days it was lower than at 15.
- HARDNESS 7.0 kgf (Measured in Monsanto Equipment). DISINTEGRATION ⁇ 60 Minutes
- the improvement of Quality of Life was in 83.3% of the cancerous patients treated with the product constitutes a finding not reported by the literature for these pathologies that are characterized by a hypercatabolic state that compromises the different vital functions. This effect is also due to the specific antianemic effect determined by the iron content of high bioavailability to the amino acid content in total concentration of 20-30 ⁇ mol / 100 ⁇ L of proteins which exert vital functions for the organism such as hemoglobin synthesis, platelets , leukocytes and immunological activity. Table 11.- Quality of life indicators in cancer patients.
- Group EA Patients who received the product prophylactically or therapeutically
- Group IIB Control Group that did not receive the product. Regardless of the location of the neoplasm in three of the main indicators, the response was positive in at least 75% of the patients who received the product, while in the controls the aggravation of these indicators was in most cases up to 100%
