What is the meaning of sustained release formulation?
Definition of sustained-release : designed to release a drug in the body slowly over an extended period of time.
What is sustained release drug?
Sustained release allows delivery of a specific drug at a programmed rate that leads to drug delivery for a prolonged period of time (Moghimi et al., 2001). This approach of drug release is especially useful for drugs that are metabolized too fast and are eliminated from the body shortly after administration.
What is sustain release drug delivery?
Sustained Release Drug Delivery System (SRDDS) is designed to release a drug at a predetermined rate by maintaining a constant drug level for a specific period of time with minimum side effects.
How do I make sustained release tablets?
Sustained release matrix tablet can be prepared in two ways, one is direct compression of the powder blend containing the drug, polymer and other additives, and another one involves granulation prior to compression. Selection of the proper method depends on the properties of the drug, polymer and other ingredients.
What is difference between sustained release and extended release?
Sustained release’s definition is more akin to a “controlled release” rather than “sustained”. Extended-release dosage consists of either sustained-release (SR) or controlled-release (CR) dosage. SR maintains drug release over a sustained period but not at a constant rate.
What is SR medication?
Sustained-release medications are usually labeled with “SR” at the end of their name. These medications prolong the medication’s release from a tablet or capsule so that you’ll get the medication’s benefits over a longer period of time. This means that you may need to take fewer doses throughout the day.

What is the difference between SR and PR?
While prolonged release tablets are meant to effect after some time from the moment they are administered and they are known to be released in small portions over a long period of time with no specifications to time or rate of concentration. Sustained release tablets are more of a controlled release.
