Conventional drug delivery systems are known to provide an immediate release of a drug with little control over where the drug is released or the time period of release. Controlled drug delivery systems offer control over the drug release timing and target site. Osmotic pumps are a promising system for controlled drug delivery. These systems are used for both oral administration and implantation. Laser drilling is one of the most commonly used techniques to create a delivery orifice in the osmotic tablet.
