Rennie heartburn tablets instructions. Method of administration of Rennie and dose. Reasons for admission

Diseases that affect the gastrointestinal tract are considered perhaps the most common in the world. This sounds sad, but stomach lesions, as a rule, occur in childhood. And developing as they grow older, they move into chronic form. It takes a long time to eliminate such diseases. In most cases, gastric diseases require lifelong adherence to a certain diet. In this article we'll talk about the drug "Rennie" and what it helps with.

Why do stomach diseases occur?

According to medical research, the number of patients who go to hospitals with complaints of stomach and intestinal diseases is increasing every day. Such diseases affect people of any age, from schoolchildren to retirees. The risk group includes those who do not notice or ignore proper nutrition, is constantly nervous, exhausts himself with various diets, smokes.

Factors that provoke the appearance stomach diseases, great amount. Among them, it is worth highlighting several reasons that become the culprits of diseases of the digestive system:

• bad habits;
• unbalanced diet;
• taking antibiotics.

Characteristic

According to the instructions, "Renny" - complex remedy, a drug with an antacid effect that helps to instantly neutralize excess hydrochloric acid in gastric juice.

"Rennie" is produced in the form chewable tablets who have square shape, with concave surfaces. The color is milky to light brown, the aroma is menthol, mint or orange. Each pack contains instructions for use of the drug "Rennie".

The tablets are packaged in strips of two, with a total of eighteen strips in the package. The drug is also placed in blisters of six pieces, with a total of two, four, six, eight or sixteen cells in the package.

Active ingredients contained in the structure of the medication:

1. Calcium carbonate.
2. Magnesium carbonate.

Additional substances in the composition of the drug "Rennie":

• sucrose;
• gelatinized corn starch;
• magnesium salt and stearic acid;
• liquid light paraffin;
• peppermint oil;
• hard transparent acacia resin;
• dextrine maltose;
• silica;
• lemon oil;
• water.

Pharmacological actions

What does “Rennie” help with? From the instructions for use of the drug it is known that it is considered an antacid medication. Included in its structure active ingredients provide rapid and long-lasting neutralization of hydrochloric acid in gastric juice, which has a protective effect on the mucous membrane of the digestive organs.

The pharmacological effect is achieved in three to five minutes, which is due to high concentration calcium and good solubility of tablets.

Subsequently, the interaction of the active substances with gastric juice in the stomach results in the formation of soluble magnesium and calcium salts. The extent of absorption of substances derived from these compounds depends on the dosage.

According to the instructions for the drug "Rennie", the maximum values ​​​​of the indicator are: calcium - ten percent, magnesium - twenty percent. Absorbed calcium and magnesium are excreted in urine in small quantities.

Insoluble compounds are formed from soluble salts in the intestines, which are subsequently eliminated with feces.

Indications

What does Rennie save you from? Typically, the drug is prescribed for symptoms that are associated with increased acidity stomach, namely:

• Heartburn (burning sensation in chest which is accompanied by discomfort varying degrees manifestations).
• Heaviness or feeling of fullness in the stomach.
• Painful sensations in the gastrointestinal tract.
• Dyspeptic symptoms (violation normal functioning stomach, difficult and painful digestion).

Contraindications

The following conditions are prohibited for use:

• Hypercalcemia.
• Nephrocalcinosis (diffuse deposition of calcium salts in kidney tissue, accompanied by inflammatory-sclerotic changes and renal failure).
• Severe kidney disease.
• Hypophosphatemia (a condition of the body in which the concentration of phosphates in the blood decreases below the physiological level).
• Age up to twelve years.
• Fructose intolerance, isomaltase deficiency.
• Glucose-galactose malabsorption ( hereditary syndrome, provoked by impaired absorption of monosaccharides in the stomach).

Can I take the drug during pregnancy?

After conception in female body almost everything is changing, and the main restructuring is taking place in hormonal background. These changes do not always affect the woman’s condition in a good way.

So, increased amount progesterone significantly relaxes the muscles of the uterus, as well as the fibers of the postural ring, which serves as a protective barrier that prevents the backflow of food and hydrochloric acid from the stomach cavity into the esophagus.

What does “Rennie” help with? From the instructions for use of the drug it is known that such disturbances in the functioning of the sphincter apparatus become a source of heartburn. Being in " interesting position", with these painful sensations even those representatives of the fair half who have never experienced them before encounter them.

There is an opinion about the safety of this disease for a pregnant woman and fetus. However, indirect manifestations of heartburn still need to be taken into account.

Firstly, constant attacks are too exhausting expectant mother- She is always irritated and depressed. Negative emotions can affect the psychological and physical development child.

Secondly, constant attacks of heartburn can aggravate a woman’s existing stomach and intestinal diseases, which will also not have the best effect on the unborn baby.

Obviously, even with occasional symptoms of acid dyspepsia, the expectant mother should inform her doctor about this. The medical specialist will select the most appropriate antacid medication for the woman’s delicate condition. Medical practice shows that it is safest to use Rennie during pregnancy.

According to the instructions for the tablets, this is one of the few medications that doctors do not prohibit the use of pregnant women and young mothers who are breastfeeding.

Despite the fact that it is possible to take Rennie during pregnancy for heartburn, these categories of patients must use the drug very carefully, only as prescribed by a doctor. Plus throughout the entire therapy medical specialist should monitor changes in the woman’s body and, if necessary, adjust treatment.

A one-time use of Rennie tablets, as a rule, does not provoke adverse reactions. Among the advantages of the drug for pregnant women, it is necessary to highlight, first of all, that it does not cause edema. The drug also does not cause constipation, which is considered the most common problem in pregnant women.

And, of course, it should be noted that it is useful for expectant mothers to take products containing calcium and medications, which include “Rennie”.

"Renny" for heartburn

The drug can be used when heartburn occurs or to prevent its occurrence. The drug should be placed in oral cavity and hold until completely dissolved or chew. Depending on the degree of occurrence negative signs, at one time it is allowed to use from one to two pieces.

The drug "Rennie" for heartburn is used according to the following scheme:

1. For a single attack of heartburn - one or two tablets, depending on the severity of the negative manifestations.
2. Repeated use of the drug is carried out two to three hours after the first use, one or two tablets.
3. You are allowed to take no more than twelve tablets per day, and only on the recommendation of a doctor.

Despite the fact that the manufacturer of the drug allows the use of a large dosage of the drug, reaching such a number is dangerous for health. When treating heartburn, you must remember that you should not take medications with water. It significantly reduces efficiency active substances medicines.

Pharmacological action of the drug Rennie

Rennie contains antacid substances - calcium carbonate and magnesium carbonate, which provide rapid and long-lasting neutralization of excess hydrochloric acid of gastric juice, thereby having a protective effect on the gastric mucosa. Achieving a positive effect within 3–5 minutes is due to the good solubility of the tablets and high calcium content. As a result of the interaction of rennie with gastric juice, soluble calcium and magnesium salts are formed in the stomach. The level of absorption of calcium and magnesium from these compounds depends on the dose of the drug. Maximum level absorption - 10% calcium and 15–20% magnesium. A small amount of absorbed calcium and magnesium is excreted through the kidneys. If renal function is impaired, plasma calcium and magnesium concentrations may increase. In the intestines, insoluble compounds are formed from soluble salts, which are excreted in the feces.

Positive Impact Rennie is not limited only to the acid-neutralizing activity of its components. Calcium and magnesium cations are capable of binding bile acids in the lumen of the stomach. At the same time, at low pH values, the binding of calcium ions to bile acids increases, while at pH = 6, conjugation processes are minimal. Calcium ions interact to a greater extent with bile acids than magnesium ions. It is important that calcium and magnesium are more tropic specifically for lipophilic bile acids, in particular deoxycholic and taurocholic acids, which are characterized by the greatest cytotoxicity (Simanenkov V.I. et al.).

An important feature of the drug Rennie is the speed of onset of the antacid effect, due to the rapid increase in intragastric pH. This is supported by the results of a double-blind, placebo-controlled study comparing the time to gastric pH >3.0 with Rennie, ranitidine, famotidine and placebo. The analysis showed that the target gastric pH value was reached after 5.8, 64.9, 70.1 and 240.0 minutes, respectively.

When prescribing antacids containing calcium carbonate, doctors are often afraid of the development of “acid rebound” (an increase in the production of hydrochloric acid after stopping the drug). A number of studies evaluating acid rebound after a single dose of 1 or 2 Rennie tablets have demonstrated that the average gastric pH within 60–90 (and 90–120, 120–150, and 150–180) minutes after administration of the drug , has no statistically significant differences compared to pH values ​​after taking placebo. The absence of “acid rebound” is explained by the magnesium included in Rennie, which can act as an antagonist of calcium-induced gastric hypersecretion (A.S. Trukhmanov, Yu.V. Evsyutina).

Indications for use Rennie

Symptoms associated with increased acidity of gastric juice and reflux zophagitis: heartburn, belching, periodic pain in the stomach; feeling of fullness or heaviness in the epigastric region; flatulence, dyspepsia (including those caused by errors in diet, intake medicines, abuse of alcohol, coffee, nicotine); dyspepsia in pregnant women.

Rennie is recommended for use in the “on demand” mode. Calcium carbonate, which is part of the drug, has a rapid and long-lasting acid-neutralizing effect, enhanced by magnesium carbonate. In the stomach, calcium carbonate and magnesium carbonate react with hydrochloric acid in gastric juice to form water, soluble mineral salts and carbon dioxide:

CaCO 3 +2HCl→CaCl 2 +H 2 O + CO 2,

MgCO 3 +2HCl→MgCl 2 +H 2 O+CO2.

Statistically significant increase The pH in the stomach is noted from the first minutes of taking the drug, and on average after 2.5–5.8 minutes the pH in the stomach exceeds 3 (Simanenkov V.I. et al.).

Contraindications

• severe renal failure
• hypercalcemia
• hypersensitivity to Rennie's components

Directions for use: Rennie and dosage

Adults and children over 12 years of age: unless otherwise recommended by a doctor, when symptoms appear, chew 1-2 Rennie tablets or keep in the mouth until completely dissolved. If necessary, you can repeat Rennie's dose after 2 hours. The maximum daily dose is 11 Rennie tablets.

special instructions: Patients with impaired renal function are not recommended to take the drug for a long time in high doses. When prescribing Rennie to patients with impaired renal function, the concentration of magnesium and calcium in the blood serum should be regularly monitored. Taking high doses of Rennie may increase the risk of kidney stones.

Long-term use high doses in combination with milk or dairy products can cause the development of milk-alkali syndrome.

Instructions for patients with diabetes mellitus: 1 Rennie tablet contains 475 mg of sucrose. 1 sugar-free Rennie tablet contains 400 mg of sorbitol and saccharin and can be used by patients with diabetes. If the use of the drug is ineffective, you should consult a doctor for advice.

Heartburn in expectant mothers can occur at any stage. At the beginning of pregnancy, this unpleasant symptom is associated with a natural decrease in the activity of smooth muscles of all organs, including the gastric sphincter, against the background hormonal changes. Gastric juice and food particles are thrown back into the esophagus and cause a burning sensation. Towards the end of pregnancy, heartburn develops due to the increasing size of the uterus, which puts pressure on many organs, including the stomach.

During pregnancy, Rennie helps eliminate heartburn quickly and without harm to the baby. Thanks to its safety and fast action received this drug wide use among expectant mothers.

Rennie – antacid drug. It is intended to eliminate acid-dependent conditions and pathologies gastrointestinal tract. The active substances are magnesium and calcium carbonate. These compounds are able to quickly and permanently neutralize excess hydrochloric acid. As a result, the mucous membrane of the esophagus and stomach is not irritated and a feeling of discomfort does not arise.

Rennie tablets dissolve well and contain a large amount of calcium, due to which their effect appears within 3 minutes. After the reaction of active substances with hydrochloric acid, magnesium and calcium salts are formed. They pass from the stomach to the intestines and exit the body in feces. About 10-20% of the elements are absorbed and partially excreted by the kidneys.

Taking other medications with Rennie is not recommended, as the rate and extent of their absorption may be reduced. The interval between the antacid and the other drug should be at least one hour.

Rennie is available in the form of chewable tablets. Pharmacies offer options with menthol, orange and mint scents. All tablets are white, square with rounded edges and engraved with the words "RENNIE" on both sides.

Depending on the dosage and duration of use, you can purchase the most suitable number of tablets. The package can contain 12, 24, 36, 48 or 96 pieces. The minimum cost is 150 rubles.

Indications and contraindications

Is it possible to use Rennie during pregnancy? Yes, the instructions for the drug say that dyspepsia during this period is one of the direct indications. Only a small part of calcium and magnesium (10-20%) is absorbed into the blood and therefore significant impact cannot affect the fruit. For the most part medicinal compounds are excreted along with feces.

The main indication for prescribing Rennie during pregnancy is heartburn and gastroesophageal reflux. The drug quickly eliminates unpleasant symptoms, but does not affect the cause of their occurrence, so it is necessary to take the tablet only when pronounced discomfort appears in the stomach or esophagus (burning, pressure, pain, etc.).

Rennie is also shown when functional disorders from the outside digestive tract. After taking it:

• Eliminates belching, accumulation of gases, burning sensation in the epigastric area, and a feeling of fullness in the stomach;
• smooth muscle motility is restored;
• Dyspeptic symptoms are reduced.

How symptomatic remedy Rennie can be used in complex treatment diseases of the gastrointestinal tract that were observed before pregnancy and worsened during it. Duration of admission and daily dosage drugs are prescribed individually.

Despite the safety of Rennie during pregnancy, the instructions for use prohibit its use in case of individual hypersensitivity to components, fructose intolerance (for options with menthol and mint scent), as well as in case of renal failure and nephrocalcinosis.

Mode of application

Rennie during pregnancy should be taken in the same way as during other periods: dissolving or chewing 1-2 tablets immediately after the onset of symptoms of dyspepsia (heartburn, belching, bloating, flatulence). If necessary, you can repeat it after 2 hours. Maximum dosage per day – 11 tablets.

But you need to take into account that Rennie supplies the body with calcium, so if the doctor additionally prescribes drugs with this element, then their intake will require adjustment.

Side effects

Rennie is well tolerated by pregnant women and side effects develop extremely rarely. In some cases (with long-term use or overdose) allergic reactions may occur, most often skin reactions, changes in stool density, and diarrhea. After a certain time after taking the tablet, a compensatory increase in the acidity of gastric juice is possible.

In women with impaired renal function, hypercalcemia and hypermagnesemia may develop during long-term treatment. Patients suffering from diabetes mellitus must take into account the sucrose content in the drug (475 mg/piece).

Safe analogues

You can get rid of moderate heartburn without the use of medications. Regular use alkaline mineral water(Essentuki, Borjomi) neutralizes hydrochloric acid thanks to the presence of baking soda in it. In order to eliminate the burning sensation, 1 glass of drink is enough. Before you drink it, you need to release the gas from the water.

From pharmaceuticals You can replace Rennie with Tams or Andrews antacid tablets. They are his structural analogues(the active ingredients are the same). The drugs Gaviscon and Maalox have the same effect.

During pregnancy, Rennie quickly eliminates heartburn and other dyspeptic symptoms; reviews from many expectant mothers confirm this. It is safe at any time and, if the dosage is observed, practically does not cause adverse reactions. However, you should take the tablets as prescribed by your doctor, as they interfere with the action of other medications (for example, those containing iron and calcium).
