According to the FDA, the mean elimination half-life of bupropion, the active ingredient in Wellbutrin, is approximately 21 hours after chronic dosing. The answer to how long does Wellbutrin stay in your bloodstream is complex, as several factors, including active metabolites and individual differences, affect its complete removal.

Etizolam, a thienodiazepine with potent sedative properties, has an average elimination half-life of about 3.4 to 6.3 hours [1.5.1, 1.5.2]. Understanding **how long does etizolam last in urine?** is critical due to its potential for misuse and detection in drug screenings.

While the spironolactone molecule itself has a half-life of only about 1.4 to 1.5 hours, its active metabolites, particularly canrenone, remain in the body much longer. Due to these longer-acting byproducts, it typically takes 5 to 7 days for spironolactone to be fully out of your body after your last dose.

The vast majority of drug biotransformation, over 70-80%, is handled by a specific family of enzymes known as Cytochrome P450 [1.6.1]. So, **what does it mean when a drug is biotransformed?** It is the process by which the body chemically alters a drug to facilitate its elimination [1.2.3, 1.2.6].

Klonopin, the brand name for clonazepam, is a long-acting benzodiazepine with a half-life ranging from 30 to 40 hours. Because of this long-lasting nature, yes, Klonopin can and often does show up on a drug test, though detection depends on the type of test and other key variables.
