3.3. Precautions while using Myopain 50 The most commonly reported adverse reactions with tolperisone are hypersensitivity reactions. Specifically as follows:
Mild skin reactions: Appearance of rash, redness, urticaria, itching; Severe systemic reactions: Anaphylaxis; Angioedema, tachycardia, low blood pressure, shortness of breath. Females have a higher risk of hypersensitivity reactions or patients with a history of allergy or hypersensitivity to other drugs.
Patients sensitive to lidocaine should use caution when using tolperisone because cross-reactivity may occur.
Before use, patients should be aware of the potential for side effects when using tolperison. If you experience side effects while using the drug, you need to stop taking the drug and inform your doctor about the situation, seek appropriate advice. In the event of an adverse reaction, tolperison should not be re-administered.
For pregnant women: Animal studies have shown that tolperison is not teratogenic. However, human studies are lacking in clinical data, so caution should be exercised when using the drug in pregnant women, carefully weighing the benefits and risks when using the drug. In particular, pregnant women in the first 3 months of pregnancy are not allowed to use tolperison. Lactation: There are no adequate studies on whether tolperison is excreted in human milk. Therefore, the use of drugs is not indicated for this group of subjects. For the ability to drive and use machines: The drug can cause dizziness, lightheadedness, difficulty concentrating, blurred vision, so consider using the drug before driving or operating machinery.
4. Drug interactions
Pharmacokinetic interaction studies on the CYP2D6 metabolizing enzyme with the substrate dextromethorphan showed that concomitant use of tolperisone may increase blood concentrations of drugs metabolised mainly by CYP2D6 such as thioridazine, tolterodin, venlafaxine, desipramine , dextromethorphan, metoprolol, nebivolol, perphenazine.
In vitro studies in human liver lobules and hepatocytes have shown no inhibition or reaction on other CYP isoenzymes (CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP1A2, CYP3A4).
In contrast, tolperisone concentrations were not affected by co-administration with drugs metabolised via CYP2D6 because tolperisone may be metabolized by other pathways.
The bioavailability of tolperisone is reduced if the drug is not taken with a meal. Therefore, patients should take the drug with meals or immediately after eating.
Myopain 50 is a centrally acting muscle relaxant with little sedation. In the case of concomitant use of tolperisone with other centrally acting muscle relaxants, a dose reduction of tolperisone should be considered if necessary. Tolperisone may potentiate the effects of niflumic acid, so a dose reduction of niflumic acid or other NSAIDs should be considered when co-administered with tolperisone.
In summary, the drug Myopain 50 has the main ingredient Tolperison, which belongs to the group of muscle relaxants and increases muscle tone. In order for the use of Myopain 50 to be effective, patients need to take the drug exactly as directed by the doctor or pharmacist.
