Respitose is a pharmaceutical excipient used as a bulking agent in the production of solid dosage forms such as tablets and capsules. As with any pharmaceutical substance, it must meet strict purity standards. Respitose impurities refer to any substances that are present in the product that are not the desired active ingredient or the excipient itself. These impurities can have negative effects on the safety and efficacy of the final product, so it is important to carefully monitor and control them during the manufacturing process.
