Immediate release medications work quickly just as their name suggests. They go into the system quickly and start relieving pain. The advantage to them is they start working quickly but often the disadvantage is the relief does not last longer than a few hours.
Also some patients describe almost a roller-coaster type of relief with immediate release medications. The pain is high, they take the medication, it begins working, it starts working well for a few hours and then starts tapering off. It is then that they would need to take another tablet. Some patients are not bothered by taking multiple tablets throughout the day and immediate release medications work well for them.
Examples of immediate release medications would be Percocet and Norco. Extended release medications on the other hand are generally only taken once or twice a day. They are specially made capsules designed to provide a pre-designated amount of medication throughout the day. Source: WebMD , Drugs. What are extended-release medications? What are the advantages of extended-release medications? Extended-release medications offer several advantages which include, but are not limited to, the following: Less frequent doses Fewer side effects Less fluctuation in blood levels Complete absorption How are extended-release medications labeled?

Marijuana can be inhaled, smoked, or ingested with food or tea, and requires a prescription from a healthcare provider. Due to recent changes in opioid prescribing, the In the formulation of conventional drug products, no deliberate effort is made to modify the drug release rate.
Immediate-release products generally result in relatively rapid drug absorption and onset of accompanying pharmacodynamic effects. In the case of conventional oral products containing prodrugs, the pharmacodynamic activity may be slow due to conversion to the active drug by hepatic or intestinal metabolism or by chemical hydrolysis.
Alternatively, conventional oral products containing poorly soluble lipophilic drugs , drug absorption may be gradual due to slow dissolution in or selective absorption across the GI tract, also resulting in a delayed onset time. The pattern of drug release from modified-release MR dosage forms is deliberately changed from that of a conventional immediate-release dosage formulation to achieve a desired therapeutic objective or better patient compliance. Several types of modified-release oral drug products are recognized:.
Extended-release drug products. A dosage form that allows at least a twofold reduction in dosage frequency as compared to that drug presented as an immediate-release conventional dosage form.
Examples of extended-release dosage forms include controlled-release, sustained-release, and long-acting drug products. Delayed-release drug products. A dosage form that releases a discrete portion or portions of drug at a time other than promptly after administration.
An initial portion may be released promptly after administration. Enteric-coated dosage forms are common delayed-release products eg, enteric-coated aspririn and other NSAID products. Targeted-release drug products. A dosage form that releases drug at or near the intended physiologic site of action see Chapter Targeted-release dosage forms may have either immediate- or extended-release characteristics.
Orally disintegrating tablets ODT. ODT have been developed to disintegrate rapidly in the saliva after oral administration. ODT may be used without the addition of water.
The drug is dispersed in saliva and swallowed with little or no water. The term controlled-release drug product was previously used to describe various types of oral extended-release-rate dosage forms, including sustained-release, sustained-action, prolonged-action, long-action, slow-release, and programmed drug delivery.
