Metamizole, also known as dipyrone, is a potent analgesic and antipyretic medication used to relieve severe pain, fever, and muscle spasms that are unresponsive to other treatments. It has been widely used in the European Union for decades and is available in oral, suppository, and injectable forms. Metamizole works by inhibiting the production of prostaglandins, which are involved in pain and inflammation.
Despite its efficacy, metamizole is not approved in some countries due to the potential risk of rare but serious side effects, such as agranulocytosis (a severe drop in white blood cell count).

As with all pharmaceutical compounds, impurities may develop in metamizole during its manufacturing, storage, or handling. Regulatory authorities enforce strict guidelines to monitor and control these impurities, ensuring the medication’s safety, efficacy, and quality.
Related Substances
These are chemically related compounds or byproducts formed during the synthesis of metamizole. Monitoring these related substances ensures the drug’s purity and therapeutic effectiveness.
Degradation Products
Metamizole can degrade under improper storage conditions, such as exposure to light, heat, or moisture. Proper storage is essential to maintain its stability and effectiveness.
Residual Solvents
Trace amounts of solvents used during manufacturing may remain in the final product. Regulatory standards ensure these solvents are within permissible limits to minimize risks to patients.
Analytical Techniques for Monitoring Impurities
Techniques such as High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (LC-MS) are commonly used to detect and quantify impurities, ensuring metamizole meets stringent safety and quality standards.
Metamizole is used to treat severe pain, high fever, and muscle spasms that are not controlled with other medications. It is particularly effective for postoperative pain, colic, and cancer-related pain.
Yes, metamizole is generally considered stronger than ibuprofen in managing severe pain. It is often used when NSAIDs like ibuprofen are insufficient or contraindicated.
Metamizole is safe for most people when used as prescribed. However, it carries a rare but serious risk of agranulocytosis (a severe drop in white blood cell count). Regular monitoring and medical supervision are recommended, particularly for prolonged use.
Yes, metamizole is typically stronger than paracetamol in managing severe pain and high fever. It is often reserved for cases where paracetamol or other first-line treatments are ineffective.
