Co-administration of trihexyphenidyl with Madopar HBS did not affect the pharmacokinetics of levodopa; Concomitant use of Madopar HBS with antacids reduces the extent of absorption of levodopa. Iron sulphate may reduce the maximum plasma concentration and AUC of levodopa; Metoclopramide may increase the rate of absorption of levodopa. 6.2 Pharmacodynamic interactions Opioids, sedatives and reserpine-containing antihypertensives all inhibit the effect of Madopar; If Madopar is to be used in patients receiving irreversible and non-selective MAO inhibitors, the MAO inhibitors should be discontinued at least 2 weeks prior to treatment with Madopar. Otherwise, side effects such as high blood pressure may occur; Selective MAO-B inhibitors (including selegiline and rasagiline) and selective MAO-A inhibitors (such as moclobemide) may be indicated for patients taking Madopar. The dose of levodopa should be adjusted individually for each patient based on efficacy and tolerability; The combination of MAO-A and MAO-B inhibitors is equivalent to non-selective MAO inhibitors, so this combination should not be used with Madopar; Do not take Madopar with epinephrine, norepinephrine, isoproterenol or amphetamine (sympathomimetic stimulants) because levodopa can increase the effects of these drugs. If necessary, the cardiovascular system should be closely monitored, the dose of sympathomimetic drugs should be reduced; Concomitant use of antipsychotics with dopamine receptor blocking properties may antagonize the antiparkinsonian effects of Madopar. Levodopa may reduce the antipsychotic effects of these drugs, so caution should be exercised when combining them. 6.3 Other drug interactions Madopar 250mg can be combined with other drugs such as: anticholinergics, selegiline, amantadine, bromocriptine and dopamine agonists but may increase desired effects and side effects. Therefore, it is necessary to reduce the dose of Madopar or the above drugs. When starting treatment with COMT inhibitors, the dose of Madopar should be reduced; Anticholinergics should not be stopped suddenly when starting Madopar because levodopa takes time to work; Levodopa can also affect the results of some tests for catecholamines, creatinine, uric acid, and glucose. Urine test results may give false positives for ketone bodies. The coombs test may give false positive results if performed in patients receiving Madopar; The effectiveness of Madopar is reduced when it is taken with a high-protein meal; Madopar should be discontinued 12 to 48 hours before surgery requiring general anesthesia with halothane to avoid the risk of blood pressure fluctuations and cardiac arrhythmias.
