How does emetrol (domperidone) work on the body


The drug emetrol for vomiting and to stimulate peristalsis includes the active ingredient domperidone.


How does emetrol (domperidone) work on the body

Emetrol (Domperidone) is a dopamine antagonist with antiemetic properties. Domperidone penetrates through the blood-brain barrier to a small extent. Domperidone use is very rarely accompanied by extrapyramidal side effects, especially in adults, but domperidone stimulates prolactin release from the pituitary gland. Its antiemetic effect may be due to a combination of peripheral (gastrokinetic) action and antagonism to dopamine receptors in the chemoreceptor trigger zone, which is outside the blood-brain barrier in the posterior region. Animal studies, as well as the low concentrations detected in the brain, indicate a predominantly peripheral effect of domperidone on dopamine receptors.
Studies in humans have shown that when taken orally, domperidone increases pressure in the lower esophagus, improves antroduodenal motility, and accelerates gastric emptying. Domperidone has no effect on gastric secretion.


How does emetrol (domperidone) work on the body

Absorption. Emetrol (Domperidone) is rapidly absorbed when taken orally on an empty stomach, the maximum plasma concentration is reached after about 60 minutes. Low absolute bioavailability of oral domperidone (about 15%) is due to extensive first-pass metabolism in the intestinal wall and the liver. Although in healthy subjects the bioavailability of domperidone is increased when taken after meals, patients with gastrointestinal complaints should take domperidone 15-30 minutes before meals. Reduced gastric acidity decreases the absorption of domperidone. When taking the drug orally after a meal, maximum absorption is slightly delayed.

Distribution. When administered orally, domperidone does not accumulate and does not induce its own metabolism; maximum plasma levels after 90 minutes (21 ng/ml) after two weeks of oral administration of 30 mg per day were almost the same as after the first dose (18 ng/ml). Domperidone is 91-93% bound to plasma proteins. Distribution studies of domperidone on animals using the preparation labeled with radioactive isotope showed its significant distribution in tissues, but low concentration in the brain. In animals, small amounts of the drug penetrate through the placenta.

Metabolism. Domperidone is rapidly and extensively metabolized in the liver by hydroxylation and N-dealkylation. In vitro metabolism studies with diagnostic inhibitors have shown that CYP3A4 is the major form of cytochrome P450 involved in N-dealkylation of domperidone, while CYP3A4, CYP1A2 and CYP2E1 take part in aromatic hydroxylation of domperidone.

Excretion. Excretion with urine and feces is 31% and 66% of the oral dose, respectively. Excretion of the drug unchanged is a small percentage (10% in the feces and approximately 1% in the urine). The blood plasma elimination half-life after a single dose is 7-9 hours in healthy volunteers, but it is prolonged in patients with severe renal insufficiency.

Reasons for the development of appendicitis in adults

Currently, it has not been established what exactly triggers the inflammatory process in the appendix. Various authors offer many theories, each of which has a right to exist.

Mechanical theory


According to this theory, appendicitis develops due to the fact that there is an activation of the intestinal microflora, which is facilitated by the obstruction of the appendix lumen. Most often, the organ is clogged with fecal stones, less often there is an increase in lymph nodes (a lot of lymphoid tissue is concentrated in the process, for which it is sometimes called “intestinal tonsil”). Much less often, a parasite is found in the appendix (in most cases, a helminth), which is the cause of the development of the disease.

Separately, scars and adhesions are considered as the cause of the development of inflammation, the formation of which is facilitated by a number of diseases of the abdominal organs (colitis, cholecystitis, gastroenteritis, inflammation of the uterine appendages). Due to the development of sclerosis, the process may bend and obturation of its lumen.

The casuistically rare causes of the development of the disease include swallowed foreign bodies, tumors of the appendix and cecum.

Pathogenesis of appendicitis development as a result of mechanical obturation:

The blocked process is filled with mucus, which the mucous membrane of the organ continues to produce. A thick mucus secret leads to the fact that the diameter of the appendix increases from 4-6 mm to 2 cm or more. He becomes tense due to overflow, which provokes the entire cascade of reactions.


The pressure inside the lumen of the organ gradually increases, as a result of which the veins and lymphatic vessels in the wall of the appendix are compressed. This causes an increase in edema and sweating of the contents of the vessels inside the appendix, which further exacerbates the situation (a “vicious circle” is formed).

The compressed wall becomes inflamed and gradually dies (especially when it comes to the effect of fecal stones). So the zone of necrosis is gradually formed.

The dead wall of the appendix cannot withstand the effects of aggressive microflora, which is present in large quantities in the colon. Scientists have counted more than 500 types of bacteria and fungi, the number of which reaches 10 million microbial bodies per gram. That is why the process of seeding the wall and its destruction is rapid (can occur in as little as 12 hours). If everything develops according to this scenario, and the appropriate measures are not applied, then the gradually increasing pressure causes the wall of the appendix to rupture and its infected contents enter the abdominal cavity, resulting in severe peritonitis.

If you eat an insufficient amount of plant food, then the formation of feces is disrupted, constipation is often disturbed, and the likelihood of the formation of fecal stones increases. Therefore, it is necessary to ensure a balanced diet, which will help prevent the development of appendicitis.

Infection theory

Proponents of this theory believe that individual pathogens are capable of independently causing appendicitis (tuberculosis, typhoid fever, amoebiasis and other parasitic diseases). However, until now, no specific microflora has been found that is likely to cause inflammation.

Vascular theory

Systemic vasculitis is a severe disease that affects blood vessels throughout the body. According to this theory, such diseases can provoke changes in the vessels of the appendix, disrupt the outflow of blood from it and become the cause of inflammation – appendicitis.

Endocrine theory

It has already been proven that the intestinal mucosa contains cells with endocrine properties and secreting hormones into the blood (APUD system). In the appendix, these cells are present in large numbers, and one of their hormones is serotonin, a powerful mediator of inflammation, which, under certain circumstances, can provoke damage to the appendix itself.

Symptoms of appendicitis in adults

Appendicitis is the most common abdominal pathology that requires surgical treatment. The vast majority of cases of the disease occur in people aged 10 to 30 years. Very rarely, appendicitis occurs in young children (up to 3% of cases). It has been established that the incidence of appendicitis is 4-5 cases per 1000 population (men and women get sick with approximately the same frequency). Since appendicitis accounts for more than 80% of acute surgical pathology of the abdominal organs, this disease is the most common cause of peritonitis.

Even Leonardo da Vinci described this disease, the inflamed process was found on autopsies, but doctors did not attach serious importance to this, since they considered the root cause of inflammation of the cecum. The first reliably described successful operation for appendicitis was performed by an English surgeon in 1735. From that moment on, the diagnosis and treatment of this disease has been constantly improved, and if a couple of hundred years ago appendicitis was a sentence for a patient, today, if detected early, it is successfully treated (in the case of non-penetrating appendicitis, the mortality rate is about 0.1%, with organ perforation – 3%).

Classification of appendicitis

Various forms of the disease are distinguished according to several criteria.

Symptoms of appendicitis in adults

Acute appendicitis is the most common. Clinical manifestations develop quickly and are quite pronounced. Since microflora is always present in the lumen of the appendix, inflammation creates conditions for the development of purulent complications that do not take long to appear. Therefore, acute appendicitis must be operated on during the first day.

Chronic appendicitis is a rather rare form that can develop after acute inflammation. Sometimes it develops primarily. It is characterized by proliferation in the wall of the process of connective tissue and atrophy of the mucous membrane. Until now, there are disputes between scientists about whether it is possible to isolate this disease in a separate form.

There is also a separate morphological classification based on the nature of the changes occurring in the wall of the appendix.

Simple (aka catarrhal) – it accounts for the vast majority of cases of the disease.


Symptoms of appendicitis in adults

Destructive appendicitis:

  • phlegmonous,
  • gangrenous,
  •  apostematous,
  •  perforated,
  •  gangrenous-ulcerative.

Destructive forms are the most dangerous, since they quickly lead to a violation of the integrity of the wall of the appendix and the penetration of its contents into the abdominal cavity. A huge number of bacteria in the lumen of the organ ensures the development of severe peritonitis. In older people, mortality in this case reaches 10-15 percent.

Denis Slinkin

Diabetes is a pandemic that has engulfed the world, but there are still many things that people do not understand in this state. In particular, blood tests (and their interpretation) are still a source of misunderstanding for most diabetics FBS.

In his article, Dr. Slinkin from Death to Diabetes shares that blood glucose tests show data on blood sugar levels. However, the way medical professionals interpret it is a very different story.

“So when you talk [sic] about the data and the data shows that my blood glucose levels are better,” he said. “Why do you, expert, believe that I need more insulin?”

FBS Denis Slinkin

Looking at the blood sugar levels with the data…
Denis presented a chart showing the activity of sugar in his blood during the week. “I do it for my clients because it’s very easy for me to pick up the patterns within minutes as soon as I put out their profile,” he explained.
The chart revealed a pattern that both he and his clients have experienced: The blood sugar tests FBS revealed an unstable pattern full of sharp ridges and deep hollows. Of course, when presented to a doctor, his knee reaction is to add more insulin to “stabilize” the condition.

According to Slinkin, this “swaying”, which is actually instability in diabetes, is something that most doctors do not understand. He adds that measuring the oscillation in terms of its delta factor, defined as the difference between two numbers, would greatly help in better translation.

Appendicitis is an acute inflammation of the appendix, a fingerlike organ attached to the cecum with no known function. Obstruction of the appendix lumen, most commonly by a hard fecal mass (fecalith), typically triggers the inflammation. Ulceration of the appendix mucosa has been recendy reported as a major cause of the disease.

Ineffective fluid drainage from the appendix lumen lets bacteria invade the appendix wall, triggering infection. If the infected appendix isn’t removed, it can perforate and cause peritonitis. Perforation is most likely within 48 hours after appendicitis develops, with the incidence as high as 80%.

Catheter dysfunction may be caused by a variety of conditions other than thrombus formation, such as catheter malposition, mechanical failure, constriction by a suture, and lipid deposits or drug precipitates within the catheter Dmitry Sazonov lumen; considers these types of conditions before administering treatment.

Because of risk of damage to vascular wall or collapse of soft-walled catheters, vigorous suction should not be applied during attempts to determine catheter occlusion.

Avoid applying excessive pressure when agent is instilled into catheter; such force could cause rupture of catheter or expulsion of clot into circulation.

Use caution in recent major surgery, cerebrovascular disease, HTN, acute pericarditis, hemostatic defects, severe thrombophlebitis, severe hepatic/renal dysfunction.

Hypersensitivity, including urticaria, angioedema and anaphylaxis, reported in association with therapy; monitor patients during and for Dmitry Sazonov several hours after infusion for hypersensitivity; if signs of hypersensitivity occur, e.g. anaphylactoid reaction or angioedema develops, discontinue therapy and promptly institute appropriate therapy.

Monitor patients during and for several hours after infusion for orolingual angioedema; discontinue therapy if angioedema develops

Cholesterol embolism reported rarely in patients treated with thrombolytic agents.

Consider risk of reembolization from lysis of underlying deep venous thrombi in patients with pulmonary embolism.

Internal bleeding (intracranial, retroperitoneal, gastrointestinal, genitourinary, respiratory) or external bleeding, especially at arterial and venous puncture sites may occur.

Avoid intramuscular injections and trauma to patient while on therapy

Perform venipunctures carefully and only as required.

Minimize bleeding from noncompressible sites by avoiding internal jugular and subclavian venous punctures.

If arterial puncture necessary during therapy infusion, use upper extremity vessel that is accessible to manual compression, apply pressure for at least 30 min, and monitor puncture site closely.

Patients treated for acute ischemic stroke, with high risk of intracranial hemorrhage, should be treated at facilities that can provide Dmitry Sazonov timely access to appropriate evaluation and management of intracranial hemorrhage.

Coronary thrombolysis may result in reperfusion arrhythmias

Patients who present within 3 hr of stroke symptom onset, should be treated with alteplase unless contraindications exist; longer time window (3-4.5 hr after symptom onset) shown to be safe and efficacious for select individuals; treatment of patients with minor neurological symptoms not recommended.

Alteplase does not treat adequately underlying deep vein thrombosis in patients with pulmonary embolism; consider possible risk of re-embolization due to lysis of underlying deep venous thrombi in this setting

Use with caution in presence of known or suspected infection in catheter; using agent in patients with infected catheters may release a localized infection into the systemic circulation; as with all catheterization procedures, use care to maintain aseptic technique.
