Celexa vs Citalopram: are they the same?
Celexa is a commercial brand whose active ingredient is exactly Citalopram. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Celexa contains Citalopram as its active ingredient. Talking about "Celexa" in clinical terms is the same as talking about Citalopram at the dose strengths 10mg, 20mg, 40mg. The differences from the authorised generic are brand, manufacturer (Forest Laboratories / AbbVie), excipients, tablet appearance and price — not the active molecule itself.
When Celexa is used
セレクサは大うつ病性障害の治療に承認されています。全般性不安症、パニック症、社交不安症、心的外傷後ストレス症、強迫症、月経前不快気分障害に対して適応外で広く使用されています。現行のうつ病ガイドラインによれば、シタロプラムはセルトラリンおよびエスシタロプラムとともに第一選択のSSRIの一つで、患者要因と処方医の慣れに基づいて選択します。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: シタロプラムはセロトニン再取り込み輸送体を選択的に阻害し、シナプスのセロトニン利用率を増加させます。一方、ノルアドレナリン輸送体や他の受容体に対する親和性は限られています。この選択性と良好なオフターゲットプロファイルにより、セレクサは旧来の抗うつ薬よりも薬物相互作用が少ないという特徴があります。治療効果は4~6週間の継続投与を経て発現します。約35時間の半減期により、安定した1日1回投与が可能となり、パロキセチンやベンラファキシンよりも…
Brand or generic — which to choose?
For most patients, authorised generics of Citalopram are clinically equivalent substitutes for Celexa and typically cost substantially less. The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
