Pulsed release is a dosage form that releases drugs at regular intervals according to therapeutic needs and can be applied to the treatment of certain diseases. Pulse drug release, also known as timed drug release system, can be based on the specific rhythms of different people’s diseases, according to the characteristics of biological time rhythms, designed to release the effective therapeutic amount of drugs at regular intervals in a pulsed manner. Pulsed release can be used to prevent morbidity, minimize adverse drug reactions, reduce the development of drug resistance, enhance the population’s compliance to treatment, and also help to achieve optimal therapeutic efficacy. This type of treatment regimen is suitable for diseases that require immediate drug concentration at night or upon awakening, such as insomnia and asthma; it can also be used for diseases in the lower parts of the intestines, such as colon cancer and ulcerative colitis. Whether or not to apply pulse-release medication can be done under the advice of a doctor.
