美沙拉秦【药物名称】中文通用名称:美沙拉秦英文通用名称:Mesalazine其它名称:5-氨基水杨酸、艾迪莎、氨水杨酸、美少胺、颇得斯安、5-Aminosalicylic Acid、5-ASA、Asacolitin、Claversal、Enterasin、Etiasa、Fisalamine、Mesalamine、Mesalazinum、Mesasal、Pentasa、Pentasa-R、Rowasa、Salofalk、Saloflk【临床应用】用于治疗溃疡性结肠炎、Crohn病(节段性肠炎)。
【药理】1.药效学本药为抗溃疡药,通过作用于肠道炎症粘膜,抑制引起炎症的前列腺素合成及炎性介质白三烯的形成,从而对肠道壁起显著的抗炎作用,对发炎的肠壁结缔组织效果尤佳。
试验表明本药对维持溃疡性结肠炎的缓解与柳氮磺吡啶同样有效,但不发生后者通常引起的不良反应(如骨髓抑制和男性不育)。
2.药动学本药口服在结肠释放后转化为乙酰水杨酸。
乙酸水杨酸一部分被肠道内细菌分解,从粪便中排出。
另一部分由肠粘膜吸收,约40%与血浆蛋白结合,在体内代谢生成乙酰化物,此乙酰化物约80%与血浆蛋白结合,从尿中排出,半衰期为5-10小时,很少透过胎盘和分泌入乳汁。
本药缓释片由乙基纤维素包衣的美沙拉秦微颗粒(直径为0.7-1mm)组成。
在胃中开始崩解,微颗粒通过幽门进入小肠,在肠道内可持续均匀地释放美沙拉秦,约50%在小肠内释放,50%在大肠内释放。
口服缓释片无需胃排空,无药物大量倾释现象,无血药峰浓度,在胃中残留时间短,服药后20分钟内血中即可测出美沙拉秦。
缓释片还可防止美沙拉秦在近端小肠被过早吸收,从而保证它在远端小肠具有较高的生物利用度。
本药栓剂由缓释微囊组成,可直接到达作用部位,缓慢释放,局部浓度高。
【注意事项】1.禁忌症 (1)对本药成分或水杨酸类药物过敏者。
(2)消化性溃疡活动期。
(3)严重肾衰竭。
(以上均选自国外资料)2.慎用 (1)血尿素氮升高或蛋白尿患者。

![0.98元一片的美沙拉嗪,使用时要牢记这四大用药细节](https://img.taocdn.com/s3/m/10b85c795627a5e9856a561252d380eb6394236b.png)
0.98元一片的美沙拉嗪,使用时要牢记这四大用药细节
美沙拉嗪又叫5-氨基水杨酸,与阿司匹林相似。
可以作用于肠粘膜的炎症部位,抑制炎症介质的形成。
是治疗包括溃疡性结肠炎在内的炎症性肠病的一线治疗药物。
虽然很多人听说过这个药物,但是该怎么用,使用时需要注意哪些事情,想必大多数人都不是很清楚,以至于降低药物治疗效果。
今天咱们就来盘点下,服用美沙拉嗪肠溶片时,该注意哪些用药细节。
细节一、使用方法
美沙拉嗪肠溶片,顾名思义,是在片剂的外面包裹了一层“肠衣”,这层肠衣到达肠道后才会崩解释放出美沙拉嗪。
因此,服用该药物时,应在餐前1小时服用。
对于溃疡性结肠炎急性期,可每天服用三次,每次0.5-1g,维持期给药频次不变,单次给药剂量需变更为0.5g。
治疗克罗恩病时,一天服用三次,每次0.5-1.5g。
细节二、用药疗程
有研究表明,对于初发或者轻症的患者,在规律治疗一段时间,症状完全缓解后,可以停药观察。
但大多数的患者需要长期规律治疗,至少3-5年,严重的甚至需要终生治疗。
细节三、定期监测
美沙拉嗪服用过程中,可能对血液系统,肝肾功产生损伤,通常发生在用药后两周。
因此,建议定期监测血常规、肝功能和肾功能。
刚开始每4周监测一次,如果期间未有异常,可延长监测间隔至每3个月监测一次。
细节四、经济性
市面上常见的美沙拉嗪肠溶片,规格为0.25g,每盒含有24片,价格为23.68元,相当于每片的价格只有0.98元,对于需要长期服用的溃结性患者,还是非常友好的。

【不良反应】少见,治疗开始时可能会出现头痛、恶心、呕吐等症状。
【禁忌】1对水杨酸制剂过敏者。
2孕妇和哺乳期妇女。
【适应症】对肠壁的炎症有显著的抑制作用;美沙拉嗪可以抑制引起炎症的前列腺素的合成和炎性介质白三烯的形成,从而对肠粘膜的炎症起显著抑制作用。
对有炎症的肠壁的结缔组织效果更佳。
用于溃疡性结肠炎、溃疡性直肠炎和克隆氏病(CrohnsDisease)【药物相互作用】如与其他药物同时使用可能会发生,详情请咨询医师或药师。
【药理毒理】艾迪莎在结肠内释放5-氨基水杨酸,在局部发挥作用后随粪便排出,在结肠的实际吸收率几乎为零。
5-氨基水杨酸的半衰期为1小时,主要代谢产物是乙酰化5-氨基水杨酸,乙酰化过程主要发生在肝脏。

APRISO may be taken without regard to meals. APRISO should not be co-administered with antacids. An evaluation of renal function is recommended before initiating therapy with APRISO. 3 DOSAGE FORMS AND STRENGTHSExtended-release capsules containing 0.375 g mesalamine. 4 CONTRAINDICATIONSAPRISO is contraindicated in patients with hypersensitivity to salicylates or aminosalicylates or to any of the components of APRISO capsules. 5 WARNINGS AND PRECAUTIONS5.1 Renal ImpairmentRenal impairment, including minimal change nephropathy, acute and chronic interstitial nephritis, and, rarely, renal failure, has been reported in patients given products such as APRISO that contain mesalamine or are converted to mesalamine. It is recommended that patients have an evaluation of renal function prior to initiation of APRISO therapy and periodically while on therapy. Exercise caution when using APRISO in patients with known renal dysfunction or a history of renal disease. In animal studies, the kidney was the principal organ for toxicity [See Nonclinical Toxicology (13.2)] 5.2 Mesalamine-Induced Acute Intolerance SyndromeMesalamine has been associated with an acute intolerance syndrome that may be difficult to distinguish from a flare of inflammatory bowel disease. Although the exact frequency of occurrence has not been determined, it has occurred in 3% of patients in controlled clinical trials of mesalamine or sulfasalazine. Symptoms include cramping, acute abdominal pain and bloody diarrhea, sometimes fever, headache, and rash. If acute intolerance syndrome is suspected, promptly discontinue treatment with APRISO.42 5.3 Hypersensitivity43 Some patients who have experienced a hypersensitivity reaction to sulfasalazine may have a44 similar reaction to APRISO capsules or to other compounds that contain or are converted to45 mesalamine.46Impairment47 5.4 Hepatic48 There have been reports of hepatic failure in patients with pre-existing liver disease who have49 been administered mesalamine. Caution should be exercised when administering APRISO to50 patients with liver disease.51REACTIONS52 6 ADVERSE53 6.1 Clinical Studies Experience54 The data described below reflect exposure to APRISO in 557 patients, including 354 exposed55 for at least 6 months and 250 exposed for greater than one year. APRISO was studied in two56 placebo-controlled trials (n = 367 treated with APRISO) and in one open-label, long-term57 study (n = 190 additional patients). The population consisted of patients with ulcerative58 colitis; the mean age was 47 years, 54% were female, and 93% were white. Patients received59 doses of APRISO 1.5 g administered orally once per day for six months in the placebo60 controlled trials and for up to 24 months in the open-label study.6162 Because clinical studies are conducted under widely varying conditions, adverse reaction63 rates observed in the clinical trials of a drug cannot be directly compared to rates in the64 clinical trials of another drug and may not reflect the rates observed in practice.6566 In the two placebo-controlled trials, 59% of APRISO-treated patients experienced an adverse67 reaction compared with 64% of placebo patients. Most adverse reactions with APRISO were68 mild or moderate in severity. Severe adverse reactions occurred in 6% of APRISO-treated69 patients and 5% of placebo-treated patients. Discontinuations due to adverse reactions70 occurred in 11% of APRISO-treated patients and 17% of placebo-treated patients; the most71 common adverse reaction resulting in study discontinuation was recurrence of ulcerative72 colitis (APRISO 6%, placebo 14%). The most common reactions reported with APRISO73 (≥3%) are shown in Table 1 below.7475 Table 1: Treatment-Emergent Adverse Reactions during Clinical Trials76 Occurring in at Least 3% of APRISO-Treated Patients77 and at a Greater Rate than with PlaceboMedDRA Preferred Term APRISO 1.5 g/dayN=367 Placebo N=185Headache 11% 8%Diarrhea 8%7% Abdominal Pain Upper 5% 3%Nausea 4%3% Nasopharyngitis 4%3% Influenza & Influenza-like illness 4% 4%Sinusitis 3%3%7879 The following adverse reactions, presented by body system, were reported at a frequency less80 than 3% in patients treated with APRISO for up to 24 months in controlled and open-label81 trials.8283 Ear and Labyrinth Disorders: tinnitus, vertigo8485 Dermatological Disorder: alopecia8687 Gastrointestinal: abdominal pain lower, rectal hemorrhage8889 Laboratory Abnormalities: increased triglycerides, decreased hematocrit and hemoglobin9091 General Disorders and Administration Site Disorders: fatigue9293 Hepatic: hepatitis cholestatic, transaminases increased9495 Renal Disorders: creatinine clearance decreased, hematuria9697 Musculoskeletal: pain, arthralgia9899 Respiratory: dyspnea100101 6.2 Adverse Reaction Information from Other Sources102 The following adverse reactions have been identified during clinical trials of a product103 similar to APRISO and post approval use of other mesalamine-containing products such as104 APRISO. Because many of these reactions are reported voluntarily from a population of105 unknown size, it is not always possible to reliably estimate their frequency or establish a106 causal relationship to drug exposure.107108 Body as a Whole: lupus-like syndrome, drug fever109 Cardiovascular: pericarditis, pericardial effusion, myocarditis110 Gastrointestinal: pancreatitis, cholecystitis, gastritis, gastroenteritis, gastrointestinal bleeding, 111 perforated peptic ulcer112 Hepatic: jaundice, cholestatic jaundice, hepatitis, liver necrosis, liver failure, Kawasaki-like 113 syndrome including changes in liver enzymes114 Hematologic: agranulocytosis, aplastic anemia115 Neurological/Psychiatric: peripheral neuropathy, Guillain-Barré syndrome, transverse116 myelitis117 Respiratory/Pulmonary: eosinophilic pneumonia, interstitial pneumonitis118 Skin: psoriasis, pyoderma gangrenosum, erythema nodosum119 Renal/Urogenital: reversible oligospermia120121 7 DRUGINTERACTIONS122 Based on in vitro studies, APRISO is not expected to inhibit the metabolism of drugs that are 123 substrates of CYP1A2, CYP2C9, CYP2C19, CYP2D6, or CYP3A4.124125 7.1 Antacids126 Because the dissolution of the coating of the granules in APRISO capsules depends on pH, 127 APRISO capsules should not be co-administered with antacids.128129 8 USE IN SPECIFIC POPULATIONS130 8.1 Pregnancy131 Pregnancy Category B. Reproduction studies with mesalamine have been performed in rats 132 at oral doses up to 320 mg/kg/day (about 1.7 times the recommended human dose based on a 133 body surface area comparison) and rabbits at doses up to 495 mg/kg/day (about 5.4 times the 134 recommended human dose based on a body surface area comparison) and have revealed no 135 evidence of impaired fertility or harm to the fetus due to mesalamine. There are, however, 136 no adequate and well-controlled studies in pregnant women. Because animal reproduction 137 studies are not always predictive of human response, this drug should be used during138 pregnancy only if clearly needed.139140 Mesalamine is known to cross the placental barrier.141142 8.3 NursingMothers143 Low concentrations of mesalamine and higher concentrations of its N-acetyl metabolite have 144 been detected in human breast milk. The clinical significance of this has not been145 determined and there is limited experience of nursing women using mesalamine. Caution 146 should be exercised when APRISO is administered to a nursing woman.147Use148 8.4 Pediatric149 Safety and effectiveness of APRISO capsules in pediatric patients have not been established.150Use151 8.5 Geriatric152 Clinical studies of APRISO did not include sufficient numbers of subjects aged 65 and over 153 to determine whether they respond differently than younger subjects. Other reported clinical 154 experience has not identified differences in responses between elderly and younger patients. 155 In general, the greater frequency of decreased hepatic, renal, or cardiac function, and of156 concomitant disease or other drug therapy in elderly patients should be considered when 157 prescribing APRISO.158159 Reports from uncontrolled clinical studies and postmarketing reporting systems suggested a 160 higher incidence of blood dyscrasias, i.e., neutropenia, pancytopenia, in patients who were 65 161 years or older who were taking mesalamine-containing products such as APRISO. Caution 162 should be taken to closely monitor blood cell counts during mesalamine therapy.163164 Mesalamine is known to be substantially excreted by the kidney, and the risk of adverse165 reactions to this drug may be greater in patients with impaired renal function. Because166 elderly patients are more likely to have decreased renal function, care should be taken when 167 prescribing this drug therapy. [see Warning and Precautions (5.1)].168169 10 OVERDOSAGE170 APRISO is an aminosalicylate, and symptoms of salicylate toxicity include hematemesis, 171 tachypnea, hyperpnea, tinnitus, deafness, lethargy, seizures, confusion, or dyspnea. Severe 172 intoxication may lead to electrolyte and blood pH imbalance and potentially to other organ 173 (e.g., renal and liver) involvement. There is no specific antidote for mesalamine overdose; 174 however, conventional therapy for salicylate toxicity may be beneficial in the event of acute 175 overdosage. This includes prevention of further gastrointestinal tract absorption by emesis 176 and, if necessary, by gastric lavage. Fluid and electrolyte imbalance should be corrected by 177 the administration of appropriate intravenous therapy. Adequate renal function should be 178 maintained. APRISO is a pH-dependent delayed-release product and this factor should be 179 considered when treating a suspected overdose.180181 11 DESCRIPTION182 Each APRISO capsule is a delayed- and extended-release dosage form for oral183 administration. Each capsule contains 0.375 g of mesalamine USP (5-aminosalicylic acid, 184 5-ASA), an anti-inflammatory drug. The structural formula of mesalamine is:185OHN2OHOH186187 Molecular Weight: 153.14188 Molecular Formula: C7H7NO3189190 Each APRISO capsule contains granules composed of mesalamine in a polymer matrix with 191 an enteric coating that dissolves at pH 6 and above.192193 The inactive ingredients of APRISO capsules are colloidal silicon dioxide, magnesium194 stearate, microcrystalline cellulose, simethicone emulsion, ethylacrylate/methylmethacrylate 195 copolymer nonoxynol 100 dispersion, hypromellose, methacrylic acid copolymer, talc,196 titanium dioxide, triethyl citrate, aspartame, anhydrous citric acid, povidone, vanilla flavor, 197 and edible black ink.198199 12 CLINICALPHARMACOLOGY200 12.1 Mechanism of Action201202203204 pathways, i.e., leukotrienes and hydroxyeicosatetraenoic acids, is increased in patients with 205 ulcerative colitis, and it is possible that 5-ASA diminishes inflammation by blocking206 production of arachidonic acid metabolites.207208 12.3 Pharmacokinetics209 Absorption210 The pharmacokinetics of 5-ASA and its metabolite, N-acetyl-5-aminosalicylic acid (N-Ac-5211 ASA), were studied after a single and multiple oral doses of 1.5 g APRISO in a crossover 212 study in healthy subjects under fasting conditions. In the multiple-dose period, each subject 213 received APRISO 1.5 g (4 x 0.375 g capsules) every 24 hours (QD) for 7 consecutive days. 214 Steady state was reached on Day 6 of QD dosing based on trough concentrations.215216 After single and multiple doses of APRISO, peak plasma concentrations were observed at 217 about 4 hours post dose. At steady state, moderate increases (1.5-fold and 1.7-fold) in218 systemic exposure (AUC0-24) to 5-ASA and N-Ac-5-ASA were observed when compared 219 with a single-dose of APRISO.220221 Pharmacokinetic parameters after a single dose of 1.5 g APRISO and at steady state in222 healthy subjects under fasting condition are shown in Table 2.223224 Table 2: Single Dose and Multiple Dose Mean (±SD) Plasma Pharmacokinetic 225 Parameters of Mesalamine (5-ASA) and N-Ac-5-ASA226 after 1.5 g APRISO Administration in Healthy SubjectsMesalamine (5-ASA) Single Dose(n=24)Multiple Dose c(n=24)AUC0-24 (µg*h/mL) 11 ± 5 AUC0-inf (µg*h/mL) 14 ± 5 C max (µg/mL) 2.1 ± 1.1 T max (h) a 4 (2, 16) t½ (h)b 9 ± 717 ± 6-2.7 ± 1.1 4 (2, 8) 10 ± 8N-Ac-5-ASAAUC0-24 (µg*h/mL) 26 ± 6 AUC0-inf (µg*h/mL) 51 ± 23 C max (µg/mL) 2.8 ± 0.8 T max (h)a 4 (4, 12) t½ (h)b 12 ± 1137 ± 9-3.4 ± 0.9 5 (2, 8) 14 ± 10a Median (range);b Harmonic mean (pseudo SD); c after 7 days of treatment227228 In a separate study (n = 30), it was observed that under fasting conditions about 32% ± 11% 229 (mean ± SD) of the administered dose was systemically absorbed based on the combined 230 cumulative urinary excretion of 5-ASA and N-Ac-5-ASA over 96 hours post-dose.231232 The effect of a high fat meal intake on absorption of mesalamine granules (the same granules 233 contained in APRISO capsules) was evaluated in 30 healthy subjects. Subjects received 234 1.6 g of mesalamine granules in sachet (2 x 0.8 g) following an overnight fast or a high-fat 235 meal in a crossover study. Under fed conditions, t max for both 5-ASA and N-Ac-5-ASA was 236 prolonged by 4 and 2 hours, respectively. A high fat meal did not affect C max for 5-ASA, but 237 a 27% increase in the cumulative urinary excretion of 5-ASA was observed with a high fat 238 meal. The overall extent of absorption of N-Ac-5-ASA was not affected by a high fat meal. 239 As APRISO and mesalamine granules in sachet were bioequivalent, APRISO can be taken 240 without regard to food.241 Distribution242 In an in vitro study, at 2.5 μg/mL, mesalamine and N-Ac-5-ASA are 43 ± 6% and 78 ± 1% 243 bound, respectively, to plasma proteins. Protein binding of N-Ac-5-ASA does not appear to 244 be concentration dependent at concentrations ranging from 1 to 10 μg/mL.245 Metabolism246 The major metabolite of mesalamine is N-acetyl-5-aminosalicylic acid (N-Ac-5-ASA). It is 247 formed by N-acetyltransferase activity in the liver and intestinal mucosa.248 Elimination249 Following single and multiple doses of APRISO, the mean half-lives were 9 to 10 hours for 250 5-ASA, and 12 to 14 hours for N-Ac-5-ASA. Of the approximately 32% of the dose251 absorbed, about 2% of the dose was excreted unchanged in the urine, compared with about 252 30% of the dose excreted as N-Ac-5-ASA.253254 In Vitro Drug-Drug Interaction Study255 In an in vitro study using human liver microsomes, 5-ASA and its metabolite, N-Ac-5-ASA, 256 were shown not to inhibit the major CYP enzymes evaluated (CYP1A2, CYP2C9,257 CYP2C19, CYP2D6, and CYP3A4). Therefore, mesalamine and its metabolite are not258 expected to inhibit the metabolism of other drugs that are substrates of CYP1A2, CYP2C9, 259 CYP2C19, CYP2D6, or CYP3A4.260261 13 NONCLINICALTOXICOLOGY262 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility263 Dietary mesalamine was not carcinogenic in rats at doses as high as 480 mg/kg/day, or in 264 mice at 2000 mg/kg/day. These doses are about 2.6 and 5.4 times the recommended human265 266 dose of granulated mesalamine capsules of 1.5 g/day (30 mg/kg if 50 kg body weight assumed or 1110 mg/m2), respectively, based on body surface area. Mesalamine was267 negative in the Ames test, the mouse lymphoma cell (L5178Y/TK+/-) forward mutation test, 268 the sister chromatid exchange assay in the Chinese hamster bone marrow test, and the mouse 269 bone marrow micronucleus test. Mesalamine at oral doses up to 320 mg/kg (about 1.7 times 270 the recommended human dose based on body surface area) was found to have no effect on 271 fertility or reproductive performance in rats.272273 13.2 Animal Toxicology and/or Pharmacology274 Renal Toxicity275 Animal studies with mesalamine (13-week and 26-week oral toxicity studies in rats, and 26276 week and 52-week oral toxicity studies in dogs) have shown the kidney to be the major target 277 organ of mesalamine toxicity. Oral doses of 40 mg/kg/day (about 0.20 times the human278 dose, on the basis of body surface area) produced minimal to slight tubular injury, and doses 279 of 160 mg/kg/day (about 0.90 times the human dose, on the basis of body surface area) or 280 higher in rats produced renal lesions including tubular degeneration, tubular mineralization, 281 and papillary necrosis. Oral doses of 60 mg/kg/day (about 1.1 times the human dose, on the 282 basis of body surface area) or higher in dogs also produced renal lesions including tubular 283 atrophy, interstitial cell infiltration, chronic nephritis, and papillary necrosis.284 Overdosage285 Single oral doses of 800 mg/kg (about 2.2 times the recommended human dose, on the basis 286 of body surface area) and 1800 mg/kg (about 9.7 times the recommended human dose, on the 287 basis of body surface area) of mesalamine were lethal to mice and rats, respectively, and 288 resulted in gastrointestinal and renal toxicity.289290 14 CLINICALSTUDIES291 14.1 Ulcerative Colitis292 Two similar, randomized, double-blind, placebo-controlled, multi-center studies were293 conducted in a total of 562 adult patients in remission from ulcerative colitis. The study294 populations had a mean age of 46 years (11% age 65 years or older), were 53% female, and 295 were primarily white (92%).296297 Ulcerative colitis disease activity was assessed using a modified Sutherland Disease Activity 298 Index1 (DAI), which is a sum of four subscores based on stool frequency, rectal bleeding, 299 mucosal appearance on endoscopy, and physician’s rating of disease activity. Each subscore 300 can range from 0 to 3, for a total possible DAI score of 12.301302 At baseline, approximately 80% of patients had a total DAI score of 0 or 1.0. Patients were 303 randomized 2:1 to receive either APRISO 1.5 g or placebo once daily in the morning for six 304 months. Patients were assessed at baseline, 1 month, 3 months, and 6 months in the clinic, 305 with endoscopy performed at baseline, at end of study, or if clinical symptoms developed. 306 Relapse was defined as a rectal bleeding subscale score of 1 or more and a mucosal307 appearance subscale score of 2 or more using the DAI. The analysis of the intent-to-treat 308 population was a comparison of the proportions of patients who remained relapse-free at the 309 end of six months of treatment. For the table below (Table 3) all patients who prematurely 310 withdrew from the study for any reason were counted as relapses.311312 In both studies, the proportion of patients who remained relapse-free at six months was313 greater for APRISO than for placebo.314315 Table 3: Percentage of Patients Relapse-Free* through 6 Months316 in APRISO Maintenance Studies317APRISO1.5 g/day% (# no relapse/N)Placebo% (# no relapse/N)Difference(95% C.I.)

There were too few elderly and too few African-American patients to 323 adequately assess difference in effects in those populations.324325 The use of APRISO for treating ulcerative colitis beyond six months has not been evaluated 326 in controlled clinical trials.327328 15 REFERENCES329 1.
