But if you want to minimise the risk of burning yourself while working on the engine, you can do the cylinder compression tests while the engine is cold â if you choose to do this then remember to add 5% to your readings to allow for the heat expansion effect on the seals in the cylinder and engine.
Bupropion is a racemic mixture. The pharmacologic activity and pharmacokinetics of the individual enantiomers have not been studied. The mean elimination half-life (Â±SD) of bupropion after chronic dosing is 21 (Â±9) hours, and steady-state plasma concentrations of bupropion are reached within 8 days.
Buproprion's manufacturer sells the drug under a third name, as well: Zyban, a drug marketed to help people quit smoking. The medication is available in immediate release (75 and 100 mg tablets) and sustained release (100 and 150 mg) formulas (sold as Wellbutrin SRÂ®). It's not clear why Wellbutrin works to reduce depressive symptoms. Chemically, it's not related to any other major antidepressant.
