General description

Ritalin®ic acid is a primary blood metabolite of methylphenidate, a psychostimulant sold under trade names Concerta® and Ritalin®. This Certified Snap-N-Spike® Solution is applicable for use in LC/MS or GC/MS applications for urine drug testing, clinical toxicology, and forensic analysis. Methylphenidate is prescribed for treatment of attention-deficit hyperactivity disorder (ADHD), tachycardia, and narcolepsy.

Application

  • Genotoxicity research in non-human primates: Ritalinic acid hydrochloride, a primary metabolite of methylphenidate, is used in genetic toxicology studies to evaluate potential genotoxic effects, aiding in the assessment of safety profiles for neuropharmacological treatments (Morris et al., 2009).
  • Pharmacokinetics and mutagenicity studies: Ritalinic acid hydrochloride is used in dose-range and mutagenicity research. It helps in studying the pharmacokinetics and toxicological impact of methylphenidate, offering important insights into its safety and effectiveness in therapeutic applications (Manjanatha et al., 2008).
  • Bioequivalence and food effect studies: In clinical pharmacology, ritalinic acid hydrochloride is instrumental in conducting bioequivalence studies of dexmethylphenidate, examining the influence of food on drug absorption and metabolism, crucial for optimizing drug administration protocols (Teo et al., 2004).
  • Childhood pharmacotherapy: Research using ritalinic acid hydrochloride explores the effects of methylphenidate when administered with or without food, highlighting its impact on the plasma concentration of the drug and its acid metabolite, informing pediatric dosing guidelines (Chan et al., 1983).
  • Hyperkinetic disorders treatment studies: Ritalinic acid hydrochloride supports pharmacokinetic studies in children with hyperkinetic disorders, aiding in understanding how methylphenidate behaves within the body to improve therapeutic strategies (Hungund et al., 1979).
