There is a significant relationship between the log-transformed t1/2 (Ln (t1/2)) of SSRIs vs the RR SREs for the given SSRI in adults (a) and children and adolescents (b). A thorough literature search uncovered t1/2 data of six SSRIs for adult analysis (fluoxetine, citalopram, venlafaxine, sertraline, paroxetine and fluvoxamine) and four SSRIs for pediatric analysis (fluoxetine, citalopram, sertraline and paroxetine). A significant positive correlation was observed between the two factors in both populations (P<0.05). There is also a significant relationship between the inverse of the time to 90% (1/(T90%)) of maximum concentration (Cmax) of that drug when it is administered on a constant dosing schedule and the risk of SREs (c, P<0.05). RR SRE, relative risk of suicide-related event; SSRI, selective serotonin reuptake inhibitor.
