How long does tamsulosin stay in your system?

10 May 2011

Following intravenous or oral administration of an immediate-release formulation, the elimination half-life of Tamsulosin hydrochloride in plasma ranged from five to seven hours. Because of absorption rate-controlled pharmacokinetics with Tamsulosin hydrochloride capsules, the apparent half-life of Tamsulosin hydrochloride is approximately 9 to 13 hours in healthy volunteers and 14 to 15 hours in the target population.

How fast tamsulosin is cleared from your system may depend on whether you take the immediate release or controlled release preparations.

Medicine is cleared from ones system in 5.5 x elimination hours. So if we took the maximum elimination half life as 15 hours, then tamsulosin should be cleared in 82.5 (83) hours.
