In consideration of the proposed revision of the limit for propylene chlorohydrins, the Committee took into account the extensive available toxicological database, most notably studies conducted by the United States National Toxicology Program. These data, together with the Committee’s previous estimate of dietary intake of HPMC, indicated that levels of propylene chlorohydrins up to 1 mg/kg in HPMC were not of toxicological concern.
Hydrophilic matrices enable the controlled release of drug via the gel layer through diffusion (soluble active ingredients) and erosion (insoluble active ingredients) – with the viscosity of the polymer having a big impact on the release profile. HPMC allows pharma companies to modify the release profiles of their drugs using matrix tablet technology, providing more effective dosing and better patient compliance through reduced tablet burden. After all, once-a-day medicine is better than multiple tablets several times a day.
