What benefit do sustained release tablets provide?

Sustained release tablets are specifically designed to release their active ingredient gradually over an extended period. This mechanism allows for a more consistent level of medication in the bloodstream, avoiding the peaks and troughs associated with immediate-release formulations. By controlling the release rate, sustained release tablets can improve patient compliance by minimizing the frequency of dosing, as patients do not need to take their medication as often. This leads to more stable therapeutic levels, better management of the condition being treated, and potentially fewer side effects due to reduced fluctuation in drug concentration.

The other options do not accurately capture the value of sustained release formulations. Immediate effect and high concentration refer to characteristics typically associated with immediate-release preparations, while liquid forms are known for rapid absorption rather than sustained release.
