Definitions
- iodized protector easy to use and not expensive, should be retained to ensure an iodine balance of the thyroid before the latter undergoes the adverse effects of a nuclear accident.
- AMM Marketing authorization
- IK potassium iodide
- the doses required are: - in areas where dietary iodine intake is" normal ": 1 dose higher or equal to 30 mg of iodine;
- iodine administration must occur as soon as the alert is given, at best before the spread of the radioactive cloud.
- the degree of protection is 80% after 2 hours and 40% after 8 hours after the start of contamination in iodine-rich regions and respectively
- the MA specifies for the usual dosages a protocol of administration, in accordance with the recommendations made by the WHO in 1989:
- the pharmacokinetic information in this MA specifies for the distribution of iodides that "outside the postprandial period and for a food intake of 70 to 100 g (thus orally) the ioduremia is less than 0.20 / 100 ml.
- the circulating iodide is concentrated by the thyroid and the kidneys.
- the metabolism information in this MA specifies that "the renal clearance is 35 ml / min; it is independent of iodized intake.
- the information on the elimination of iodides from this MA specifies that "the iodide is eliminated rapidly, with a renal clearance of 35 ml / min and a half-life of about 6 hours. After 48 to 72 hours, most of unorganized iodine will be eliminated.
- the drugs already used in humans include the mixture of ethyl esters of iodized fatty acids flaxseed oil, the name of Lipiodol, used for over 20 years, in humans, injection intravenous 10-20 ml as contrast medium in radiology; at the time of his employment the doctors noted the spectacular regression of the goitre of the treated subjects.
- Lipiodol has also been used in pure form in the treatment of goitre in Africa for several years.
- the intravenous mode of administration and the quantity administered show, as a first approximation, the non-toxicity of the product.
- the goal is also to have a product with a very long duration of action.
- iodized fatty acid esters are either stored in lipid tissues and then gradually released and metabolized, or immediately metabolized in the liver as iodides, fixed in the thyroid gland or eliminated. in the urine.
- a triiodinated fatty acid ester liberates the 3 iodides
- the mono-iodine releases 1 iodide for a constant percentage of iodine administered

- the total iodine concentration of Brassiodol is 30 per cent iodine; a variation of ⁇ 5 per cent of the theoretical value is the analytical quality standard of a drug product, a value of between 28.5 per cent and 31.5 per cent.
- GUIBET monoiodostearic and 76 per cent diiodostearic acid
- Brassiodol corresponding to the concentration of 25 mg of 127
- Brassiodol is made from a mixture (origin: rapeseed oil) of 60% oleic acid (converted to mono-iodinated fatty acid), 22% linoleic acid (di-iodinated fatty acid), 8% of linolenic acid (tri-iodinated fatty acid).
- Lipiodol is made from a mixture (origin: flaxseed oil) of 30% oleic acid (converted to mono-iodinated fatty acid), 60% linoleic acid (di-iodinated fatty acid), 4 % -linolenic acid (tri-iodinated fatty acid).
- the baseline levels of iodine on D-1 and D-2 show significant iodine deficiency in both villages. There is then a very important urinary excretion of iodine at Ji and J2, then a progressive decrease of the values up to Js for the 2 groups.
- the percentage of Brassiodol representing a mixture of iodinated fatty acid ethyl esters containing 60 percent monoiodostearic acid ester, administered orally and eliminated as iodides in the urine is 17.0% the first. day, 25.3% for the first two days, 29.9% for the first three days, and 32.9% for the first five days.
- the percentage of Lipiodol representing a mixture of ethyl esters of iodinated fatty acids containing 30 percent monoiodostearic acid ester, administered orally and eliminated in the urine is 21.9% on the first day of 33%. 9% for the first two days, 39.9% for the first three days, 43.9% for the first five days.
- Brassiodol The activity of Brassiodol is several weeks while that of a tablet of IK is only two days.
- the industrial production is made from a well-defined raw material composition of fatty acids and allows to obtain a mixture of ethyl esters of iodized fatty acids of rapeseed oil with an almost quantitative yield by use of a silylated reagent giving no residual product.
- This original methodology has been the subject of the patent applicable to all the fatty acids of various vegetable oils and vegetable oils possibly enriched in oleic acid (Jung L., Ingenbleek Y., Iodinated fatty acid esters, iodized fatty acids and their derivatives , obtained by iodohydrination involving alkylsilyl derivatives with alkaline iodides and their pharmacological activities INPI Patent of Paris, National Registration No.
- Brassiodol has been developed according to the recommended quality specifications for the development of a drug: validated industrial production, quality control of the raw materials involved and the active ingredient according to established procedures, purity assured .
- Brassiodol soft capsule containing only iodized oil for a period of 10 years at + 25 ° C ⁇ 2 ° C and 60 per cent ⁇ 5 per cent relative humidity has been demonstrated.
- the iodized oil coming out of the soft capsule has a light yellow coloring; the other parameters (free iodides, total percentage of iodine, chromatography of liquid chromatography of the different ethyl esters of iodized fatty acids) are identical to those obtained at time 0 during manufacture.
- Brassiodol facilitated iodine supply, prolonged release in humans in a state of need and / or lack.
- the deficiency state can be severe
- LIPIOCIS® as a drug also makes it possible to specify certain parameters of bioavailability of the ethyl esters of iodized fatty acids.
- Ethyl esters of iodinated fatty acids 131, flaxseed oil prepared from LIPIODOL) by labeling were used under the name of
- LIPIOCIS® (CIS international bio, 91192 G if-sur-Yvette Cedex) in the treatment of hepatocarcinoma with average doses in the form of a slow and direct injection into the catheter: hepatic intra-arterial injection of 2 ml.
- Information on the bioavailability of LIPIOCIS® can be found in the data of the publication of X. WERENNE (WERENNE X. "How I treat hepatocarcinoma: contribution of interstitial brachytherapy using
- LIPIOCIS® concentration of LIPIOCIS® is 2.3 to 12 times higher in tumor cells compared to that observed in non-tumoral liver cells. The half-life times are thus 5.5 days in the normal liver and 3.5 days in the non-tumoral liver.
- the elimination of the product is mainly urinary (30 to 50% of the radioactivity is eliminated in one week with a stable rate of excretion), (http: //sante-az.aufeminin.eom/w/sante/m5586766/medicament ).
- LIPIOCIS® After hepatic intra-arterial injection.LIPIOCIS® distributes mainly in the liver and lungs. There is no medullary fixation. During the first 24 hours, 75 to 90% of the administered activity is localized in the liver and 10 to 25% in the lungs. In the liver, the tumor activity is very intense with binding ratios of the 24th hour tumor liver / non-tumor liver, between 2.3 and 12.
- Intra-tumoral fixation is done on the first pass. No recirculation was detected. However, an increase in pulmonary activity can be seen within 2 days after injection, followed by a decrease in this activity with a half-life of 4 to 5 days, which could correspond to a release of LIPIOCIS® fixed in the tumoral liver.
- the effective half-life is about 5.5 days in the tumor liver and about 3.5 days in the non-tumor liver.
- the removal is essentially urinary, 30 to 50% of the administered activity is eliminated in one week with a relatively stable excretion rate; fecal elimination is very low (3% in 5 days).
- the radioactivity measured in the blood samples is always minimal.
- the Brassiodol contains 60 percent of ethyl ester of * monoiodostéarique acid, stearic acid, physiological fatty acid, for supporting the organified iodine.
- This monoiodostearic acid ethyl ester is sequestered by various human tissues, mainly the lipids, and gradually metabolized by releasing the iodides which are subsequently organrganized by the thyroid.
- Brassiodol can be defined as pro-protective, inactive to the thyroid, becoming active only by metabolic transformation.
