<ul style="box-sizing: border-box; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px 0px 1.5em 3em; outline: 0px; padding: 0px; vertical-align: baseline; list-style: disc;">
<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">威而鋼最初不是壯陽藥，而是心臟用藥。</li>
<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">九〇年代英國藥廠進行冠狀動脈循環試驗，藥效不顯著，但受試者意外發現性能力提升。</li>
<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">醫師追問後確認，這個「副作用」才成為後來全球男性爭相使用的原因。</li>

<ul style="box-sizing: border-box; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px 0px 1.5em 3em; outline: 0px; padding: 0px; vertical-align: baseline; list-style: disc;">
<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">男性勃起靠陰莖海綿體灌血，性刺激釋放一氧化氮，使血管放鬆。</li>
<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">PDE5酵素會把信號切斷，勃起持續時間受限。</li>
<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">威而鋼可抑制PDE5，延長血液充盈海綿體時間，通常藥效維持3-4小時。</li>
<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">正確使用搭配性刺激，效果會被放大。</li>

<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">建議在性行為前約30-60分鐘服用。</li>
<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">服藥後要有互動，手到、口到、心到、眼到，才能充分發揮藥效。</li>
<li style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">藥效一天內完全代謝，不會在體內累積，不會造成永久性副作用。</li>
