Now, the daily pharmaceutical industry is focused on developing common oral dosage forms as it becomes essential medical tool. This continuous-release formulation is designed to release the drug at a predetermined rate and keep the plasma drug overflow in a medical window with minimal side effects. The basic idea behind continuous drug delivery is to change the drug's biopharmaceutical, pharmacokinetic, and pharmacodynamics to reduce side effects, provide patient compliance, and treat the disease. Continued discontinuation of drug delivery improved patient compliance due to frequent drug administration, decreased flexibility in consistent drug levels, higher drug use, increased dosage of effective drug dosage, and reduced health care costs with improved treatment and shorter treatment duration.
