Livial vs Tibolone: are they the same?
Livial is a commercial brand whose active ingredient is exactly Tibolone. 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 — Livial contains Tibolone as its active ingredient. Talking about "Livial" in clinical terms is the same as talking about Tibolone at the dose strengths 2.5mg. The differences from the authorised generic are brand, manufacturer (Aspen / Organon), excipients, tablet appearance and price — not the active molecule itself.
When Livial is used
リビアルは(認可されている国では)最後の自然月経から少なくとも12ヶ月以上経過した女性における中等度から重度の血管運動性閉経期症状の治療および閉経後骨粗鬆症の予防に承認されています。現在の欧州閉経ガイドラインによれば、リビアルはLIFT試験で高齢女性の脳卒中リスク増加が示されたため、閉経後10年以内の60歳未満の女性に制限されています。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: リビアルのチボロンは速やかに組織選択的活性を持つ3つの活性代謝物に変換されます。水酸化代謝物は骨(骨密度の維持)、脳(ホットフラッシュおよび寝汗の緩和)、膣(萎縮の軽減)におけるエストロゲン活性を持ち、Δ4代謝物はプロゲスチン活性(子宮内膜の保護)および弱いアンドロゲン活性(性欲の支持)を持ちます。このバランスのとれた組織選択性により、リビアルは複合HRTの役割を1日1錠で網羅します。
Brand or generic — which to choose?
For most patients, authorised generics of Tibolone are clinically equivalent substitutes for Livial 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.
