Oral oxycodone has a half-life of 4.5 hours. [88] It is available as a generic medication. [15] The manufacturer of OxyContin, a controlled-release preparation of oxycodone, Purdue Pharma, claimed in their 1992 patent application that the duration of action of OxyContin is 12 hours in "90% of patients". It has never performed any clinical ...

Absorption half-life 1 h, elimination half-life 12 h. Biological half-life (elimination half-life, pharmacological half-life) is the time taken for concentration of a biological substance (such as a medication) to decrease from its maximum concentration (C max) to half of C max in the blood plasma.

The elimination half-life of oxymorphone is much faster intravenously, and as such, the drug is most commonly used orally. [7] Like oxycodone, which metabolizes to oxymorphone, oxymorphone has a high potential to be abused. [8] It was developed in Germany in 1914. It was patented in 1955 and approved for medical use in 1959. [9]
Hydrocodone is used to treat moderate to severe pain. In liquid formulations, it is used to treat cough. [10] In one study comparing the potency of hydrocodone to that of oxycodone, it was found that it took 50% more hydrocodone to achieve the same degree of miosis (pupillary contraction). [26]

In pharmacokinetics, steady state refers to the situation where the overall intake of a drug is fairly in dynamic equilibrium with its elimination. In practice, it is generally considered that once regular dosing of a drug is started, steady state is reached after 3 to 5 times its half-life. In steady state and in linear pharmacokinetics, AUC ...
