Aponil

Aponil (nimesulide) is a drug used to relieve pain and inflammation. It is an anti-inflammatory drug (NSAID) that also has analgesic (painkiller) and antipyretic effects. Nimesulide is often used to relieve symptoms of rheumatic diseases, toothache, headaches, muscle pain and other conditions.

It is important to remember that the use of nimesulide should be carried out in accordance with the instructions and recommendations of the doctor. This drug may have side effects and contraindications, and self-medication with it may be dangerous. Before starting to use nimesulide, it is important to consult a medical specialist.

發布表單

Tablets are the most common form of nimesulide. Tablets can be of different dosages, which allows you to select the optimal dose for each patient.

藥效學

• Cyclooxygenase (COX) inhibition: Nimesulide inhibits the action of the enzymes COX-1 and COX-2, which are involved in the process of converting arachidonic acid into prostaglandinins. COX-2 is typically activated in response to inflammatory processes, while COX-1 is present in tissues where it performs physiological functions. By inhibiting COX-2, nimesulide reduces the synthesis of prostaglandins, which leads to a decrease in inflammation, pain and fever.
• Analgesia (pain-relieving effect): By reducing the level of prostaglandins, nimesulide has an analgesic effect, relieving pain in various conditions such as rheumatic diseases, muscle pain and headaches.
• Anti-inflammatory effect: Since prostaglandinins are key mediators of inflammation, inhibition of their synthesis helps reduce the intensity of inflammatory processes.
• Antipyretic effect: Nimesulide can reduce body temperature by affecting the hypothalamus in the brain, which regulates thermoregulation.

藥代動力學

• Absorption: Nimesulide is usually rapidly and completely absorbed from the gastrointestinal tract after oral administration. Maximum concentration in the blood is usually reached 2-4 hours after administration.
• Bioavailability: The bioavailability of nimesulide is about 90%, which means that almost the entire dose taken enters the systemic circulation.
• Metabolism: Nimesulide is metabolized in the liver. The main metabolite is 4-hydroxynimesulide, which also has pharmacological activity.
• Protein binding: About 99% of nimesulide binds to plasma proteins, mainly albumin.
• Distribution: Nimesulide is evenly distributed in the body and penetrates into various tissues.
• Excretion: Nimesulide and its metabolites are excreted mainly through the kidneys (about 50-60%) and intestines (about 40-50%) as metabolites.
• Half-life: The half-life of nimesulide is about 2-4 hours.

劑量和管理

• For adults:

  • The usual starting dose is 100 mg (1 tablet or capsule) twice daily after meals.
  • The maximum daily dose usually does not exceed 200 mg.

• For children:

  • Children are recommended to prescribe a dose of nimesulide depending on their body weight and age. Children's dosage is usually determined by the doctor based on the individual characteristics of each child.

• Duration of treatment:

  • The duration of treatment with nimesulide is usually limited to short-term use, no more than 15 days.
  • If it is necessary to continue treatment, the duration of the course should be discussed with the doctor.

• Use in elderly patients:

  • Elderly patients may require dosage adjustments based on their renal and hepatic function.

• Use in special groups:

  • During pregnancy and lactation, nimesulide is contraindicated or can only be used under strict medical supervision.
  • Patients with gastrointestinal diseases, asthma, kidney and liver diseases should be especially careful when using nimesulide.

在懷孕期間使用 Aponilla

• Risk of congenital anomalies:

  • A study from Italy found that use of nimesulide in the first trimester of pregnancy may be associated with an increased risk of congenital urinary tract anomalies in newborns. Women who took nimesulide in the first trimester had a 2.6 times higher risk of such abnormalities compared to those who did not take the drug (Cantarutti et al., 2018).

• Effects on the cardiovascular system of the fetus:

  • In another case, premature narrowing of the ductus arteriosus in the fetus was recorded, which led to hypertrophy of the right ventricle of the heart. This has been associated with maternal use of nimesulide in late pregnancy (Sciacca et al., 2005).

• Oligohydramnios:

  • Oligohidramnios (low levels of amniotic fluid) has also been reported in women taking nimesulide during pregnancy, which can lead to various complications in the fetus (Grinceviciene et al., 2016).

• Kidney failure in newborns:

  • Newborns exposed to nimesulide during pregnancy may develop acute renal failure. In one case, a child whose mother took nimesulide during the last two weeks of pregnancy developed oliguric renal failure, which gradually resolved after birth (Landau et al., 1999).

禁忌

• Peptic ulcer of the stomach and duodenum: The use of nimesulide may increase the risk of exacerbation of peptic ulcer and bleeding from the gastrointestinal tract.
• Conditions accompanied by an increased risk of bleeding: For example, hemorrhagic diathesis, bleeding disorders, hemorrhagic diathesis, etc.
• Liver failure: Nimesulide is metabolized in the liver, so its use may be contraindicated if the function of this organ is impaired.
• Kidney failure: Since nimesulide and its metabolites are excreted primarily through the kidneys, if their function is impaired, the drug may accumulate, which increases the risk of side effects.
• Asthma, runny nose with nasal polyps, and rhinitis caused by aspirin and other NSAIDs: Nimesulide may cause bronchospasm in some patients, especially in those with asthma or allergic rhinitis.
• Pregnancy and lactation: The use of nimesulide during pregnancy, especially in the third trimester, may be contraindicated due to the risk to the fetus. In addition, nimesulide can be excreted into breast milk, so its use during lactation may be undesirable.
• Children: The use of nimesulide in children under 12 years of age may be contraindicated due to the lack of sufficient data on efficacy and safety in this age group.

副作用 Aponilla

• Gastrointestinal disorders: Includes dyspepsia (stomach upset), nausea, vomiting, diarrhea, bloating and abdominal pain.
• Gastrointestinal ulcers: Nimesulide may increase the risk of developing gastric or intestinal ulcers, as well as gastrointestinal bleeding.
• Allergic reactions: Include skin rash, itching, swelling, angioedema (Angioedema), allergic dermatitis and rarely anaphylactic shock.
• Kidney and liver damage: Rarely, nimesulide may cause kidney or liver damage, which is manifested by increased blood levels.
• Central Nervous System: Headache, dizziness, drowsiness, insomnia, anxiety, and irritability may occur.

過量

Signs of overdose may include nausea, vomiting, abdominal pain, drowsiness, headache, hypertension (increased blood pressure), and possible kidney and liver dysfunction.
