The Methylphenidate(MPD) Rapid Test Cassette (Urine) is a rapid chromatographic immunoassay for the detection of Methylphenidate in urine at a cut-off concentration of 1000ng/mL.Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
Methylphenidate (Ritalin), it is a central nervous stimulant, and is mainly used in the treatment of ADHD (attention deficit hyperactivity disorder), postural orthostatic tachycardia syndrome and narcolepsy. The drug is quickly eliminated and metabolized to Ritalin acid, but about 80% (about 60% are Ritalin acid), will be excreted in the urine during 24 hours. After 20 minutes of drug-intake, it can be absorbed in the stomach, At the time of 60-90min, blood concentration reachs its peak. And its half-life in blood is 5 to 6 hours. The long-term use of ADHD stimulants decrease abnormalities in brain structure and function found in subjects with ADHD.
