Lyrica vs Pregabalin: are they the same?
Lyrica is a commercial brand whose active ingredient is exactly Pregabalin. 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 — Lyrica contains Pregabalin as its active ingredient. Talking about "Lyrica" in clinical terms is the same as talking about Pregabalin at the dose strengths 25mg, 50mg, 75mg, 100mg, 150mg, 200mg, 225mg, 300mg. The differences from the authorised generic are brand, manufacturer (Pfizer), excipients, tablet appearance and price — not the active molecule itself.
When Lyrica is used
リリカは糖尿病性末梢神経障害、帯状疱疹後神経痛、脊髄損傷およびその他の中枢性神経障害性疼痛(一部の国)に伴う神経障害性疼痛、全般性不安障害、線維筋痛症(米国およびその他一部の国)、部分発作の補助療法において成人で承認されています。国際ガイドラインによれば、プレガバリンは神経障害性疼痛における推奨される第一選択薬の一つです。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: プレガバリンは中枢神経系の電位依存性カルシウムチャネルのα2δ補助サブユニットに結合し、シナプス前のカルシウム流入とグルタミン酸、ノルアドレナリン、サブスタンスPなどの興奮性神経伝達物質の放出を減少させます。その結果、抗けいれん、抗不安、鎮痛作用が、特に神経障害性疼痛経路で得られます。
Brand or generic — which to choose?
For most patients, authorised generics of Pregabalin are clinically equivalent substitutes for Lyrica 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.
