SSRIs Rescribed

Te SSRIs dostępne są in clinical praktyka vary in their indestitic properties, half-lives, and receptor-binding profiles, which ch can influence dosing strategies and thee likelihood of drug interactions. The following agents are mott common revibed:

  • Fluoksetyna (Prozac) - long half-life (4- 6 days for thee parent drug, longer for its active metabolite norfluoksetine); often used in once- daily dosing and d eventionally in weekly formulations.
  • Sertraline (Zoloft) - pośrednim półżyciem (~ 26 godzin); linear continutics; often preferred for it favorable profile in ciąża i piersiadying.
  • Cytalopram (Celexa) - moderate half-life (~ 36 hours); risk of QT- interval prolongation at higher doses (above 40 mg / day, or 20 mg / day in older dilles).
  • Escytalopram (Lexapro) - thee S- enantiomer of citalopram; similar efectify with a cleaner side-effect profile; half-life ~ 27- 32 hours.
  • Paroxetine (Paxil) - shorter half-life (~ 21 hour); more anticholinergic side effects anda higher risk of dicontinuation syndrome; also associated witt wag gain and sexual dysfunction.

Each agent has unique specifics that may guidee selection and dosing adjustments.
