Ketotifen Related Products
Ketorolac is a potent NSAID used primarily for short-term management of moderate to severe pain, often after surgery. It works by inhibiting prostaglandin synthesis via COX enzyme blockade, providing analgesic and anti-inflammatory effects. Due to its potential for gastrointestinal, renal, and bleeding complications, it is typically prescribed for no more than 5 days and is not recommended for chronic pain management.
Cleanchem is a trusted provider of premium pharmaceutical reference materials, specializing in Ketotifen and its associated compounds. Our catalog includes pharmacopeial and non-pharmacopeial Ketotifen impurities, metabolites, nitrosamine derivatives (N-NO compounds), and stable isotope-labeled products. These reference standards play a critical role in pharmaceutical R&D, supporting activities such as product formulation, ANDA and DMF submissions, quality assurance, analytical method development, and stability assessments.
All Ketotifen-related substances undergo comprehensive characterization and are delivered with complete Certificates of Analysis and supporting analytical documentation to ensure regulatory adherence. Upon request, we can offer EP/USP traceable standards. Our products are routinely re-evaluated to maintain consistent quality and performance.
