Cipro vs Ciprofloxacin: are they the same?
Cipro is a commercial brand whose active ingredient is exactly Ciprofloxacin. 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 — Cipro contains Ciprofloxacin as its active ingredient. Talking about "Cipro" in clinical terms is the same as talking about Ciprofloxacin at the dose strengths 250mg, 500mg, 750mg. The differences from the authorised generic are brand, manufacturer (Bayer), excipients, tablet appearance and price — not the active molecule itself.
When Cipro is used
シプロは成人の複雑性尿路感染症、急性非複雑性膀胱炎(他の選択肢が適切でない場合)、腎盂腎炎、前立腺炎、感染性下痢、腸チフス、複雑性腹腔内感染症、骨・関節感染症、吸入性炭疽菌曝露の治療に承認されています。最近の規制当局の通知によれば、フルオロキノロン系は障害を引き起こし得る副作用のリスクがあるため、他の抗菌薬が適切でない状況に限定して使用すべきとされています。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: シプロフロキサシンはDNA複製、転写、修復、組換えに必須の細菌DNAジャイレースおよびトポイソメラーゼIVを阻害します。その結果、緑膿菌や多くの腸内細菌科を含む多くのグラム陰性菌に対する殺菌活性を示し、グラム陽性菌に対する活性はより変動的です。耐性は経時的に増加しており、一部の状況では経験的使用を制限しています。
Brand or generic — which to choose?
For most patients, authorised generics of Ciprofloxacin are clinically equivalent substitutes for Cipro 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.
よくある質問

Clinically yes — Cipro is the brand and Ciprofloxacin is its active ingredient. At equivalent doses (250mg, 500mg, 750mg) they produce the same effect. The difference is brand, manufacturer (Bayer) and price.
Is generic Ciprofloxacin as effective as Cipro? ▾
Yes. Authorised generics of Ciprofloxacin must demonstrate bioequivalence to the brand. The active substance is the same; average effect is the same. Price is usually substantially lower.
Why does Cipro cost more than generic Ciprofloxacin? ▾
The price difference reflects originator development costs, brand recognition and competition among generic manufacturers. The molecule is identical; the cost is not.
