Abstract:
Pulsatile flow is thought to lower pulmonary vascular resistance by passive recruitment of capillaries and by active vasodilation. This study was undertaken to investigate the role of endothelium-derived relaxing factor (EDRF) during pulsatile flow in isolated canine left lower lobes pretreated with indomethacin. The lobes were perfused in situ with autologous blood (approximately 500 ml/min) using a nonpulsatile pump (Masterflex) or a pulsatile pump (Harvard). With the occlusion techniques, vascular resistance was partitioned into four segments: arterial (Ra), small arterial (R'a), small veno

Abstract:
Drugs might be released immediately or over time. Pulsatile medication release systems, on the other hand, have been increasing in popularity in recent years. Many medications or therapies could benefit from pulsatile drug release, in which the drug is released rapidly after a predetermined lag time. Pulsatile release systems come in pairs: multi and separate pulse. Rupturable dose forms are a prominent type of single-pulse device. Other methods have a drug-containing centre covered by both a swelling surface and a semi - permeable barrier polymer layer or membrane that is semipermeable but no

Abstract:
Traditionally, drugs are released in an immediate or extended fashion. However, in recent years, pulsatile drug release systems are gaining growing interest. Pulsatile drug delivery systems are developed to deliver drug according to circadian behavior of diseases. The product follow a sigmoidal drug release profile characterized by a time period of no release (lag time) followed by a rapid and complete drug release. Pulsatile systems are gaining a lot of interest as they deliver the drug at the right site of action at the right time and in the right amount, thus providing spatial and temporal

Abstract:
Solutes are often most efficiently deployed in discrete pulses, for example in the delivery of herbicides or drugs. Manual application of each pulse can be labor-intensive, automated application of each pulse can be capital intensive, and both are often costly and impractical. Barrier-Mediated Pulsatile Release (BMPR) systems offer a materials-based alternative for automated pulsatile drug delivery, without pumps, power supplies, or complex circuitry. While earlier materials-based approaches such as delayed-release microcapsules are limited to two or three pulses due to the independent nature

Multiple dose regimens are frequently required to optimize therapy; however, such therapy is frequently undermined by poor patient adherence. In fact, patient adherence is inversely related to the number of doses a patient is asked to take each drug. Consequently, great efforts are under way to develop drug delivery systems that are able to release drugs over an extended time interval; this could offer considerable benefits including reducing administration frequency.
