第二類:非類固醇消炎止痛藥 (nonsteroidal antiinflammatory drugs,NSAIDs)

NSAID作用機轉為抑制cyclooxygenase (COX)，使花生四烯酸 (arachidonic acid) 無法代謝成前列腺素 (prostaglandins)達到止痛、消炎效果。

COX又分成兩種形式:
COX-1 : 可維持腸胃道、血小板、腎臟功能
COX-2 : 在組織受傷時才被誘發的，主要促使prostacyclin (PGI2)的生成
PGI2會誘導發炎反應而導致疼痛、腫脹及不適感。
一般常見的NSAID會同時阻斷COX-1及COX-2，阻斷COX-1會破壞腸胃道黏膜以及影響腎臟血流並且會抑制thromboxane A2(TXA2) 長期使用導致傷胃傷腎以及出血等副作用，阻斷COX-2則會減少PGI2的生成，減少發炎物質的產生達到消炎止痛的作用，但也會促使血小板凝集，而導致心肌梗塞、心絞痛、缺血性中風等心血管方面副作用的增加。

說了那麼多，那常見的NSAIDS 藥物之間又有什麼差別呢? 主要的差別在於對COX -1 /COX-2阻斷的比例，對COX-2選擇性越高，也就越不會阻斷COX-1，也較不會有傷胃及出血的副作用。

以下是常見NSAIDS藥物的介紹
1 Aspirin
Aspirin和其他同類藥物不同的地方在於他是唯一不可逆的抑制血小板凝結長達4-7天的藥物(低劑量下就有效果)，也因此在心血管用藥上佔有一席之地(目前因腸胃道副作用明顯已少用於消炎止痛) 。

2 Diclofenac
有證據說明Diclofenac能抑制Lipoxygnase pathway，減少leukotrienes的形成，另一方面抑制phospholipase A2的作用，這些額外的作用也解釋了為何Diclofenac是強度很高的NSAID之一，他的止痛效力是Indomethacin的六倍，另一方面Diclofenac 相較於選擇性COX-2 inhibitor，在高劑量 (每日150毫克)，可能會增加心肌梗塞、中風或可能致死栓塞事件的風險，此風險會隨著使用的劑量和時間上升而增加

3 Ibuprofen (很多人去日本會買的EVE主要成分)
Ibuprofen 在NSAID中腸胃道副作用方面風險是較低的，在退燒方面較為安全有效(美國FDA僅核准ibuprofen有此適應症)

4 Indomethacin
Indomethacin是一個非常強效的COX inhibitor，抗發炎效果幾乎是NSAID中最強的，但是它的副作用也比較多(心血管，腸胃道) ，目前主要用於急性痛風的治療

5 ketorolac
ketorolac是NSAID 中止痛效力最強的藥物，30mg的ketorolac約等於10mg morphine(嗎啡) ，也是目前急診室用量最大的止痛藥

6 Celecoxib
celecoxib 含有磺胺類結構，磺胺類藥物過敏的人不能使用，做為一個選擇性COX-2抑制劑，celecoxib有較少的腸胃道副作用，值得注意的是像celecoxib有-coxib字尾或者像piroxicam，meloxicam 有-xicam結尾的藥物有較長的半衰期因此也較適合用於長期慢性疼痛的病人(OA，RA)

使用NSAID藥物的時候必須考慮到病人本身的背景，有些病人不適合使用NSAID藥物，像是懷孕的婦女，使用抗凝血劑治療的病患，對aspirin或任何NSAID有過敏反應，胃潰瘍的病人等等。
但是我們也不需要過度妖魔化止痛藥，當用則用，止痛藥一般建議在疼痛剛開始時就服用，越晚服用效果可能越差，甚至要加重劑量才有效果，遵循醫生，藥師的指示下服用，才是正確使用止痛藥的原則。

【藥罐子藥房事件簿】Diclofenac事件

〈藥劑思考題：餐後服用會不會影響Diclofenac的藥效？〉

最近上午時分，一個年約二十多歲的中國籍男子，中等身材，案發當日穿著一件格仔襯衫、一條藍色牛仔褲，前來藥房打算問藥。

甫進藥房後不久，這個男生便跟藥罐子遞上一張寫著「DICLOFENAC 25MG」的長方形白色備忘紙問藥罐子：

「這是什麼藥？」

哦，Diclofenac，藥罐子當然知道這是什麼藥喇！

於是藥罐子便答道：

「哦，這是一種消炎止痛藥。」

正確一點，這其實是一種非類固醇消炎止痛藥(Non-steroidal Anti-inflammatory Drugs, NSAIDs)。

插播一下：

Diclofenac是一種非類固醇消炎止痛藥，主要透過抑制體內分布在發炎組織的環氧化酶-2(Cyclo-oxygenase-2, COX-2)的活性，減少花生四烯酸(Arachidonic Acid)的代謝，抑制前列腺素(Prostaglandin, PG)的產生，減低因為前列腺素而誘發的炎性反應，收縮血管，降低血管的通透性，紓緩炎症，減輕疼痛。

不過所謂「一不離二」，既然有環氧化酶-2，自然還有環氧化酶-1(Cyclo-oxygenase-1, COX-1)，對吧？

對，因為非類固醇消炎止痛藥還可能會抑制體內的環氧化酶-1活性，例如血管、胃壁、腎臟，從而可能會帶來副作用。

其中非類固醇消炎止痛藥還可能會影響胃壁的正常黏液分泌，削弱胃壁的自我保護機制，從而可能會增加出現胃潰瘍、胃出血的風險，導致腸胃不適，俗稱「削胃」。

所以這類藥一般建議餐後服用，減少藥物對胃部的刺激、傷害。

接著這個男生便繼續好奇追問：

「唔……如果這種NSAID跟食物同服的話，會不會影響藥效？」

首先既然他說得出「NSAID」這個字，那他一開始便應該對Diclofenac有一定的認識。看來這個男生應該做過功課吧？

問藥前做功課，絕對是一件值得鼓勵的事。這表示問藥者真的關心自己的健康，不然的話，你會花時間做功課嗎？

哦……原來剛才只不過是開場白而已……

好！現在，中場休息，大家一齊停一停、諗一諗：

「如果Diclofenac真的跟食物同服的話，到底會不會影響Diclofenac的藥效呢？」

唔……暫時只是知道Diclofenac需要跟食物同服。

其實看到這裡，各位看倌不知道有沒有發現一件事呢？

唔……既然Diclofenac需要餐後服用，那不論答案是「會」還是「不會」，是福不是禍，是禍躲不過，最後還是需要跟食物同服。

這就是說……

這條問題根本不重要。因為不論答案是什麼，結果只有一個：餐後服藥。

所以藥罐子便答道：

「唔……因為Diclofenac可能會傷胃，所以不論如何，一般還是建議飯後服藥，所以這又有什麼關係呢？」

然後這個男生便微微點頭，慢慢離開藥房了。

【藥罐子藥房事件簿】Celecoxib事件

〈不傷胃 = 不傷胃？〉

今次的案情主要是這樣的：

最近下午時分，一個年約二十多歲的女生揹著一個白色背囊前來藥房問藥。

甫進藥房後不久，這個女生便從背囊裡拿出一排藥出來並放在玻璃櫃枱上，然後指著這排藥裡面其中一粒橙白色膠囊（上半是橙色，下半是白色）開始抱怨起來。

至於這個女生到底在抱怨什麼呢？

哦，這便要從這粒藥開始說起……

據聞這個女生曾經服過一種消炎止痛藥（資料不詳），怎料服藥後便開始覺得胃痛。後來有人介紹這個女生轉用這排藥並告訴這個女生這種藥不傷胃，可惜事與願違，最後還是胃痛。

於是這個女生便疑惑道：

「這種藥其實到底傷不傷胃？」

藥罐子便拿起這排藥並翻看背面的鋁箔紙，哦，原來是Celecoxib這種非類固醇消炎止痛藥(Non-steroidal Anti-inflammatory Drugs, NSAIDs)。

唔……首先「非類固醇消炎止痛藥可能會傷胃。」這點無錯。

因為這類藥主要透過抑制體內分布在發炎組織的環氧化酶-2(Cyclo-oxygenase-2, COX-2)的活性，減少花生四烯酸(Arachidonic Acid)的代謝，從而抑制前列腺素(Prostaglandin, PG)的產生，減低因為前列腺素而誘發的炎性反應，從而收縮血管，降低血管的通透性，紓緩炎症，減輕疼痛，達到消炎止痛的效果。

同時所謂「一不離二」，既然有環氧化酶-2，自然還有環氧化酶-1(Cyclo-oxygenase-1, COX-1)，對吧？

對，因為非類固醇消炎止痛藥還可能會抑制體內胃壁的COX-1活性，便可能會影響胃壁的正常黏液分泌，削弱胃壁的自我保護機制，從而可能會增加出現胃潰瘍、胃出血的風險，導致腸胃不適，俗稱「傷胃」。

不過跟其他非類固醇消炎止痛藥不同，Celecoxib是一種環氧化酶-2選擇性抑制劑(COX-2 Selective Inhibitor)，一般擁有較大的COX-2選擇性，理論上，較少會出現腸胃不適。
　　
不過就算是環氧化酶-2選擇性抑制劑，同樣還是可能會傷胃的。不然的話，這個女生便不會胃痛，對吧？

對，環氧化酶-2選擇性抑制劑較不傷胃，不過多少只是一個相對的概念，簡單說，「少」只是「少」，不是「零」，真的要說的話，「環氧化酶-2選擇性抑制劑不會傷胃」固然適用於沉默的大多數，但是未必適用於一小撮用藥者身上，特別是一些先天不足的高風險人士，例如自身罹患十二指腸潰瘍、胃潰瘍等消化性潰瘍病症的人士，自然便不能百分百排除「傷胃」的可能。

當然傷胃不是世界末日，一般還是可以解決的。

至於常用的方法一般主要有以下三個：

一、轉藥

這是一個簡單、直接的方法。

常言道：「百貨應百客。」同理，百藥治百人；服這種藥會傷胃，不代表服那種藥會傷胃，一切因人而異。

實際上，就算是環氧化酶-2選擇性抑制劑，並不是只有Celecoxib這個選項！

對，除了Celecoxib外，其實還有其他選項，例如Etoricoxib。

所以如果真的覺得胃痛的話，不妨嘗試轉用其他環氧化酶-2選擇性抑制劑，直至找到一種真正「不傷胃」的環氧化酶-2選擇性抑制劑為止。

二、餐後服藥

就算是非類固醇消炎止痛藥，同樣建議餐後服藥，減少腸胃不適。

所以餐後服藥是其中一個可行的方法。

三、加胃藥

對，既然服藥會傷胃，那其中一個方法當然是同時服用胃藥！誰又沒有說過「服藥只能治病，不能治副作用」嘛？

所以如果餐後服藥還是不行的話，一般建議同時服用胃藥直接KO胃痛。

當然，服藥本來是希望解決問題，不料同時製造另一個問題，並且需要服其他藥KO這種藥所帶來的問題，這固然不是一個理想的用藥之道，不過這是沒辦法中的辦法。

反正只要能夠解決問題，不就行了嗎？
