Kapvay is an extended-release clonidine tablet indicated for use in patients with ADHD. Kapvay requires twice daily dosing and, in a head to head pharmacokinetic study with IR clonidine, has been shown to have a similar elimination half-life when administered at the same milligram amount.
At this time, it has not been definitively shown that Kapvay offers a cost or clinical benefit compared to clonidine IR. However, it represents a large cost increase compared to clonidine IR, at about $2.50/tablet (up to 4 tabs/day could be used). It is also important to consider that 1,359 clonidine tablet claims (66% of the total) are used in recipients <20 years of age, suggesting that the IR formulation is being used for ADHD.
