MICROIODIDE

General characteristics. Structure:

Active ingredient - potassium iodide — 130,8mkg (that corresponds to 100 mkg of iodide) Excipients: sugar milk (lactose), refined sugar (sucrose), silicon dioxide colloid (aerosil), calcium stearate. Description: Tablets of white color ploskotsilindrichesky with a facet and risky.

Pharmacological properties:

Pharmacodynamics. Iodine belongs to the irreplaceable microelements necessary for normal functioning of a thyroid gland. At intake of iodides in cells of an epithelium of a follicle of a thyroid gland iodine ions under the influence of enzyme iodide-peroxidase are oxidized with formation of elementary iodine which joins in a tyrosine molecule. At the same time one part of radicals of tyrosine in thyreoglobulin is iodated therefore it is formed tironina, thyroxine (T4) and triiodothyronine (Тз) are basic of which. Tironina form a complex with protein thyreoglobulin which is deposited in a colloid of a follicle of a thyroid gland. The iodine coming to an organism in physiological quantities prevents development of the local craw connected with a lack of iodine of food; normalizes the size of a thyroid gland at newborns, children and teenagers; influences T3/T4 ratio indicators, level of thyritropic hormone.

Pharmacokinetics. At intake it is quickly and completely soaked up in a small bowel and during 2 h it is distributed in intracellular space. Collects generally in a thyroid gland (concentration of iodide more than 500 mkg/g of fabric), and also in salivary and mammary glands, a mucous membrane of a stomach. Well gets through a placenta. It is removed preferential by kidneys (trace quantities are defined in urine in 10 min. after reception, 80% of a dose are removed during 48 h, other part — within 10-20 days), partially — with secrets of salivary, bronchial, sweat and other glands.

Indications to use:

- prevention of development of a local craw, including at pregnancy; - prevention of a recurrence of a craw after end of a course of treatment of a craw drugs of hormones of a thyroid gland or after its surgical removal; - treatment of a diffusion euthyroid craw at newborns, children, teenagers and adult patients of young age.

Route of administration and doses:

The daily dose of drug should be accepted in one step after food, washing down with a large amount of liquid. At purpose of drug newborns and children up to 3 years are recommended to dissolve a tablet in a small amount (1 tablespoon) of boiled water of room temperature. If the doctor did not appoint differently, then follow the following instructions on a dosage: Prevention of development of a local craw: Newborns and children: 50-100 mkg of iodine a day. Teenagers and adults: 100-200 mkg of iodine a day. At pregnancy and feeding by a breast: 150-200 mkg of iodine a day Prevention of a recurrence of a craw after end of a course of treatment drugs of hormones of a thyroid gland or after its surgical removal: 100 - 200 mkg of iodine daily Treatment of an euthyroid craw: Newborns, children and teenagers: 100-200 mkg of iodine a day. Adult patients of young age: 300-500 mkg of iodine a day. Preventive administration of drug is carried out within, as a rule, several months or years, in the presence of indications — for life. Treatment of a craw at newborns is carried out on average within 2-4 weeks, at children, teenagers and adults 6-12 months usually are required, long reception is possible. Duration of reception of Mikroyodid is defined by the doctor.

Features of use:

Prior to treatment it is necessary to exclude malignant damage of a thyroid gland, a hyperthyroidism or a nodal toxic craw. Against the background of therapy by drug at patients with a renal failure development of a hyperpotassemia is possible (periodic control of level of potassium in blood is necessary). Microiodide 100 does not influence ability to driving of motor transport and control of mechanisms.

Side effects:

At Mikroyodid's use 100 according to indications in the recommended doses emergence of side effects is improbable. Sometimes allergic reactions develop: skin rash, Quincke's edema. At use of drug in the dose exceeding 150mkg/days the hidden hyperthyroidism can pass into a manifest form. At prolonged use of drug in the dose exceeding 300 mkg/days development iodine - the induced hyperthyroidism is possible (especially at the elderly patients having a craw for a long time in the presence of a nodal craw or toxic adenoma).

Interaction with other medicines:

The concomitant use of anti-thyroid medicines weakens effect of potassium of iodide (mutually). Perchlorate and potassium thiocyanate suppress iodine absorption by a thyroid gland. Thyritropic hormone improves digestion of iodine a thyroid gland and stimulates production of its hormones. The concomitant use of inhibitors of an angiotensin-converting enzyme (including captopril, enalapril, lisinopril) increases risk of emergence of a hyperpotassemia. High doses of iodine in combination with kaliysberegayushchy diuretics can lead to a hyperpotassemia. Therapy co-administration by iodine in high doses and drugs of lithium promotes development of a craw and a hypothyroidism. Reduces capture by a thyroid gland 131I and 123I.

Contraindications:

The expressed thyrotoxicosis; - the latent thyrotoxicosis (at use of the doses exceeding 150 mkg/days); - herpetiform dermatitis; - toxic adenoma, a nodal craw at use in doses more than 300 mkg/days (except for preoperative therapy for the purpose of blockade of a thyroid gland); hypersensitivity to iodine. Microiodide 100 should not be accepted at a hypothyroidism unless development of the last is caused by the expressed iodine deficiency. Purpose of drug should be avoided at therapy by a radioiodine, existence or at suspicion of cancer of a thyroid gland. Due to the existence in composition of drug of lactose, patients with rare hereditary diseases, such as a lactose intolerance, deficit of lactase or glyukozo-galaktozny malabsorption should not accept drug. With care apply at patients with a renal failure.

Overdose:

Symptoms: acute overdose: coloring of mucous membranes in brown color, reflex vomiting, abdominal pains and diarrhea (perhaps, a melena). In hard cases development of dehydration and shock is possible. The chronic overdose can lead to development of a phenomenon of "iodism": "metal" smack in a mouth; hypostasis and inflammation mucous (rhinitis, conjunctivitis, gastroenteritis, bronchitis); acne rash; dermatitis; hypostasis of sialadens; fever; nervous irritability.

Treatment: at acute overdose: gastric lavage, introduction of Natrium thiosulfuricum, symptomatic therapy of disturbance of water and electrolytic balance, antishock therapy. Treatment at chronic overdose: drug withdrawal.
