This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods include jumping up and down make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.

While flutazolam has a very short half-life of only 3.5 hours, n-desalkylflurazepam has a long half-life of between 47–100 hours. [4] Flutazolam is closely related in structure to another benzodiazepine, haloxazolam. [5] [6]
Context-sensitive half-life or context sensitive half-time is defined as the time taken for blood plasma concentration of a drug to decline by one half after an infusion designed to maintain a steady state (i.e. a constant plasma concentration) has been stopped. The "context" is the duration of infusion.
