Phenolsulphonphthalein, Sulfental (Phenolsulphonphthalein)

Phenolsulphonphthalein, also known as Phenolsulphonphthalein, is a red dye that is widely used in medicine to test kidney function.

Kidney function plays an important role in maintaining human health. They are responsible for filtering the blood, removing waste and excess fluid from the body, and regulating the levels of certain substances in the blood. Kidney function testing can help identify various kidney diseases, such as chronic kidney failure, urinary tract infection, or kidney drainage problems.

Phenolsulfophthalein is used in injection form to evaluate kidney function. Once injected into a vein, the dye is filtered through the kidneys and excreted from the body through urine. The recorded volume of urine containing the dye allows one to estimate the rate of blood filtration through the kidneys.

Apart from medicinal purposes, phenolsulfophthalein is also used in other applications. For example, it can be used as a pH indicator in chemical experiments. In addition, it can be used as a skin dye in cosmetics.

Despite its widespread use, the use of phenolsulfophthalein may cause unwanted effects. In some cases, allergic reactions such as hives or anaphylactic shock may occur. In addition, with some kidney diseases, such as acute and chronic glomerulonephritis, there may be a violation of the removal of dye from the body.

In conclusion, phenolsulfophthalein, also known as Sulfenthal, is an important tool for assessing kidney function in medicine. It is widely used to detect various kidney diseases and can be used in other fields such as chemistry and cosmetology. However, it is necessary to take into account possible undesirable effects and use the dye only under the supervision of qualified medical personnel.



Phenolsulfophthalein, also known as Sulfenthal or Phenolsulphonphthalein, is a red dye that is widely used in medicine to test kidney function in patients.

One of the main methods for studying kidney function is to estimate the glomerular filtration rate (GFR). To do this, special drugs are used to help determine the rate at which the kidneys clear the blood of waste and toxins. Phenolsulfophthalein is one such drug.

The drug Phenolsulfophthalein is administered intravenously at a dose of 10 mg/kg and is quickly distributed throughout the body. After administration of the drug, its elimination through the kidneys begins. Phenolsulfophthalein has the property of binding to blood proteins and is rapidly filtered through the kidneys, which makes it possible to estimate GFR.

However, in addition to its medical use to study kidney function, Phenolsulfophthalein can also be used in other fields such as the chemical industry, drinking water quality, and as a coloring agent in the food industry.

Moreover, Phenolsulfophthalein can be used as a pH indicator. In an acidic environment it is red, and in an alkaline environment it is colorless. This property allows the drug to be used to determine the acidity or alkalinity of solutions.

However, despite all its beneficial properties, Phenolsulfophthalein may have some side effects. In some cases, it can cause an allergic reaction or unwanted symptoms from the digestive system.

Overall, Phenolsulfophthalein is an important tool for the diagnosis and study of kidney function, and also has a wide range of applications in various fields of science and industry. However, it must be used with caution and only under the supervision of qualified medical personnel.



Phenolsulfonphthalein (Phenol Sulfonphthalein), also known as sulfanilic acid or sulfanyl phthalic anhydride, is a red dye used in medicine to determine the function of the kidneys and other organs. It is used as an indicator to measure acidity levels in the body and as an excipient in some medications.

Phenolsulfophthalein is an organic compound consisting of a phenol molecule (hydroxybenzene) bound to a phthalic anhydride molecule (C10H6O4). This substance has acidic properties and can be used to measure acidity in biological fluids such as urine and blood.

In medicine, phenolsulfophthalein is used to determine glomerular filtration rate (GFR) and other kidney functions. It is also used as a marker in the study of the liver and biliary tract.

To determine GFR, phenolsulfophthalein is administered intravenously and its level in the blood is monitored. If the dye level decreases, it indicates normal kidney function, and if the level remains high, it may indicate kidney problems.

In addition, phenolsulfophthaleins are used as excipients in some drugs, for example to increase the effectiveness of some antibiotics and to enhance the effects of other drugs.

However, like any other drug, phenolsulfophthalein has its side effects. Some people may experience allergic reactions to this substance, as well as to other ingredients in the drug. In addition, the administration of phenolsulfophthalein may cause nausea, vomiting and other unpleasant symptoms, especially in people with gastrointestinal problems.

Thus, phenolsulfophthaleinn is a red dye that is used in medicine to measure kidney function and as an excipient for some medications.



Phenol sulfophthalein or sulfatelain is a red dye that is widely used in medicine for injection in kidney function tests. This substance consists of a combination of sulfophenalein and phthales. When introduced into the patient's body, sulfalenaine has an effect on blood circulation, this is associated with a change in the acidity of urine. The color change of this acid depends on the amount of salt in the blood. Usually, foods that contain acid are prescribed before the test. The study itself is carried out by introducing sulfalthalein into the patient’s bloodstream. After the reaction, the color of the biomaterial changes. The result obtained reflects the condition of the kidneys. The study helps to identify violations of the integrity of the urinary system or the presence of infectious diseases. Also, this diagnosis allows you to evaluate the effectiveness of various medications on the kidneys. Timely diagnosis can save the health and life of patients.



Phenolsulphanphthleau (phenolsulfonphthalein) is a drug that is used in medicine to diagnose the condition of the kidneys and other organs of the urinary system. It works by changing skin color when it comes into contact with uric acid.

Phenolsulfonomorphthaleoin is a red, water-soluble dye that is used to assess kidney function by injection into the bloodstream. This dye can change skin color within 1-2 minutes after injection. However, if the skin color turns pink or purple, this may indicate normal kidney function, while yellow skin color may indicate problems with kidney health.

When the dye enters the body, it reacts with the uric acid in the body and changes its color from red to yellow. This color change allows you to see how well the kidneys are filtering and eliminating uric acid from the body. If uric acid is not eliminated from the body quickly enough, it can cause jaundice.

In addition, phenolsulfonarphthaleone can also be used to detect other kidney-related diseases, such as prostate disorders and kidney diseases that are not related to kidney function. For example, in case of impaired liver function, occurring in liver acardia, liver acardia, calcifications, hereditary metabolic disorders, diseases caused by adenoma, cyst, polyps, the formation of compression, fibrous lesions, thrombosis, cancer, etc., an increase in the concentration of uric acid may be observed in blood. Indicators of acid-base balance (PO4³⁻), “calcium”, “urea”, “creatinine”, “cholesterol” in the composition of the B-17 toxin may also increase. According to the type of course, B-19 toxin has a chronic form with a possible acute onset and a chronic course with periods of exacerbation, a gradual deterioration of renal function and interstitial nephropathy, slowly progressive oliguria with proteinuria, without signs of arterial hypertension or a significant decrease in renal function as the initial condition at the time examinations. Complications of toxin B, including crystalluria, acute or chronic renal failure, ketoacidosis, electrolyte abnormalities, neonatal hyperreactivity, and psychiatric reactions, require emergency care and treatment. X-ray examination of the skeleton, ultrasound examination, computed tomography, magnetic resonance imaging of the abdominal organs, functional research methods, assessment of hepatic-cellular function, neurological examination, bacterological and virological examination of urine and biochemical blood tests, cultures of blood and urine for microflora, laboratory assistants, tumor markers, biomarkers of impaired cell reparative function, content of immunoglobulins G, A, M and M, acetyl-glutaryl aminotransferase, determination of the level of alkaline phosphatase, protein and SHB protein, calcium and phosphorus fractions
