Traditional oral drug delivery methods, which typically release medication immediately, often lead to fluctuations in plasma drug concentration, potentially causing suboptimal therapeutic outcomes and side effects. Osmotic pump drug delivery systems address these issues by providing a controlled release mechanism that ensures a steady and predictable release of the drug over an extended period. This controlled release enhances patient compliance by reducing the frequency of dosing and maintaining uniform blood concentration levels, thereby improving therapeutic efficacy. Unlike conventional drug delivery methods, osmotic pumps are less influenced by physiological variables within the gastrointestinal tract, making them a reliable and consistent option for controlled drug delivery. These systems operate on the principles of osmosis, utilizing a semipermeable membrane to regulate the influx of water into the drug-containing core, which then generates osmotic pressure to drive the drug out through a delivery orifice. This review provides an in-depth discussion of the principles behind osmotic drug delivery systems, the various types available, their benefits, and the challenges they present. It also highlights the significance of these systems in modern pharmaceutical applications, demonstrating how they represent a significant advancement over traditional methods by optimizing drug release profiles, improving patient adherence, and ultimately enhancing therapeutic outcomes
