Co z Controlled?

Controlled release is a formulation strategy in which activite is contaminate is contained into a carrier or coating that modulates it - acceptability over time. Instad of releasing thee chemical all at once, these systems deliver it continuously at a designed rate - minutes, days, weeks, or even months - dependiing on thee formulation and thee target pess 's life cycle.
