药品名称:福沙匹坦二甲葡胺粉针
英文名称:Fosaprepitant dimeglumine
商品名称:Emend[美国] Ivemend[欧洲]
分子量:1004.83
CAS号:265121-04-8
剂 型:冻干粉针
规 格:115mg、150mg/10ml
适应症:
本品与其他止吐药联用适用于防治中等和大剂量催吐抗癌化疗药( 包括大剂量顺铂) 初始和反复用药等引起的急性和迟后期恶心和呕吐。
用法用量:
本品的推荐剂量为115 mg,给药方法为静脉注射(15分钟)。
药理作用
本品是阿瑞吡坦(aprepitant) 的前体药物,注射后在体内迅速转化成阿瑞吡坦。
本品与阿瑞吡坦属人P 物质/ 神经激肽1(NK-1) 选择性高亲和性受体阻断剂,主要通过阻断大脑恶心和呕吐信号发挥作用。
在动物模型上,阿瑞吡坦通过中枢神经作用抑制诸如顺铂等细胞毒化疗药物诱导的呕吐。动物和人正电子发射断层成像术(PET) 研究表明,阿瑞吡坦可透过血脑屏障并占据了脑部NK-1 受体作用。动物和临床研究显示,阿瑞吡坦增大5-HT3受体阻断剂昂丹司琼和糖皮质激素地塞米松的止吐作用,抑制顺铂诱导的急性期和迟后期呕吐。
健康志愿者单剂量静脉注射(15分钟) 本品后,阿瑞吡坦的平均AUC0-∞为31.7 (±14.3) μg·h/mL,阿瑞吡坦平均Cmax为3.27(±1.16) μg/mL。患者静脉注射本品115mg 后
24小时阿瑞吡坦平均血药浓度和口服阿瑞吡坦125mg相当。
产品特点:
福沙吡坦2008年1月25日获得上市许可,规格为115mg和150mg,其中115mg用10ml西林瓶包装,剂型为注射用粉针,商品名为EMEND,与阿瑞匹坦的商品名相同。也在瑞典、捷克、葡萄牙和英国上市,商品名为IVEMEND,本品尚未在日本上市。福沙匹坦Base含3个手性中心,每个葡甲胺另外含4个手性中心,福沙匹坦二甲葡胺为无定形。
福沙匹坦二甲葡胺是阿瑞匹坦口服制剂的前体药物,静脉注射后迅速转化为阿瑞匹坦。115mg福沙匹坦(相当于188mg福沙匹坦二甲葡胺)在15分钟内静脉输注至人体内,输液结束后30分钟内,福沙匹坦的血药浓度即降至或低于定量限浓度10ng/ml,福沙匹坦几乎完全转化为阿瑞匹坦。
健康志愿者静脉输注115mg福沙匹坦15分钟或口服125mg阿瑞匹坦,给药后4~5小时,前者血浆中阿瑞匹坦浓度较后者高,但之后两者浓度相近。静脉输注115mg福沙匹坦二甲葡胺可取代口服125mg阿瑞匹坦胶囊。临床研究显示,本品115mg 注射与口服阿瑞吡坦125mg呈生物等效性。
Ivemend
Active Substance: fosaprepitant
Common Name: fosaprepitant
ATC Code: A04AD12
Marketing Authorisation Holder: Merck Sharp & Dohme Ltd
Active Substance: fosaprepitant
Status: Authorised
Authorisation Date: 2008-01-11
Therapeutic Area: Vomiting Cancer
Pharmacotherapeutic Group: Anti-emetics and antinauseants
Therapeutic Indication
Prevention of acute and delayed nausea and vomiting associated with highly emetogenic cisplatin-based cancer chemotherapy in adults.
Prevention of nausea and vomiting associated with moderately emetogenic cancer chemotherapy in adults.
Ivemend 115 mg is given as part of a combination therapy.
What is Ivemend?
Ivemend is a powder that is made up into a solution for infusion (drip) into a vein. It contains the active substance fosaprepitant (150 mg).
What is Ivemend used for?
Ivemend is used with other medicines to prevent nausea (feeling sick) and vomiting caused by chemotherapy (medicines used to treat cancer) in adults.
Ivemend is used for chemotherapy containing cisplatin (a strong trigger of nausea and vomiting) and for chemotherapy that is a moderate trigger of nausea and vomiting (such as cyclophosphamide, doxorubicin or epirubicin). Ivemend makes chemotherapy more tolerable for the patient.
The medicine can only be obtained with a prescription.
How is Ivemend used?
Ivemend is given as an infusion around 30 minutes before the start of chemotherapy. It is only given on the first day of chemotherapy. The infusion lasts 20 to 30 minutes.
Ivemend must always be given together with other medicines that prevent nausea and vomiting, including a corticosteroid (such as dexamethasone) and a ‘5HT3 antagonist’ (such as ondansetron).
How does Ivemend work?
The active substance in Ivemend, fosaprepitant, is a ‘prodrug’ of aprepitant. This means that it is converted to aprepitant in the body. Aprepitant is a neurokinin-1 (NK1)-receptor antagonist. It stops a chemical in the body called ‘substance P’ from attaching to the NK1 receptors. When substance P attaches to these receptors, it causes nausea and vomiting. By blocking these receptors, Ivemend can prevent nausea and vomiting, which often happens during and after chemotherapy. Aprepitant has been authorised in the European Union (EU) as Emend since 2003.
How has Ivemend been studied?
Ivemend has been studied in one main study comparing a single 150-mg infusion of Ivemend with a three-day course of Emend capsules, both in combination with ondansetron and dexamethasone. The study involved over 2,000 adults with cancer who were receiving their first course of chemotherapy including cisplatin. The main measure of effectiveness was the number of patients who did not have any nausea or vomiting over the five days after receiving chemotherapy.
What benefit has Ivemend shown during the studies?
The study showed that a single 150-mg infusion of Ivemend was as effective as a three-day course of Emend in preventing nausea and vomiting. Around 72% of both groups did not have any nausea or vomiting over the five days after receiving chemotherapy.
What is the risk associated with Ivemend?
The most common side effects with Ivemend (seen in between 1 and 10 patients in 100) are increased liver enzymes, headache, hiccups, constipation, dyspepsia (heartburn), loss of appetite and fatigue (weakness or tiredness). For the full list of all side effects reported with Ivemend, see the package leaflet.
Ivemend must not be used in people who are hypersensitive (allergic) to fosaprepitant or aprepitant, polysorbate 80 or any of the other ingredients. It must not be given at the same time as the following medicines:
· pimozide (used to treat mental illness);
· terfenadine, astemizole (commonly used to treat allergy symptoms - these medicines may be available without prescription);
· cisapride (used to relieve certain stomach problems).
See the package leaflet for full details.
Why has Ivemend been approved?
The CHMP decided that Ivemend’s benefits are greater than its risks and recommended that it be given marketing authorisation.
