注射用兰索拉唑与复方甘草酸单铵注射液存在配伍禁忌发表时间:2020-07-10T06:11:51.586Z 来源:《航空军医》2020年5期作者:王亚铎[导读](陆军第81集团医院河北张家口 075000)注射用兰索拉唑(30 mg)是一种抑制胃酸分泌药,性状为白色或类白色疏松块状物或粉末,适用于各种类型的腐蚀性食道炎治疗,如反流性食管炎、胃溃疡、十二指肠溃疡等。
脱氧核苷酸钠注射液复方甘草酸单铵注射液(5ml)为复方制剂,适用于急、慢性肝炎、药物中毒、食物中毒、药物过敏等。
在临床工作中发现,注射用兰索拉唑与复方甘草酸单铵注射液存在配伍禁忌,现报道如下;1临床资料患者,男,57 岁,2019 年10 月因慢性乙型肝炎、胃溃疡收入院,遵医嘱予0.9% 氯化钠注射液100 ml 中加入注射用兰索拉唑30 mg 静脉滴注治疗,滴注过程通畅,后又予5% 葡萄糖注射液250 ml 中加入复方甘草酸单铵注射液5ml 静脉滴注,发现在同一静脉通路的两组液体混合时,在莫非氏滴管中会出现白色絮状物,输液管中出现浑浊现象。
见状立即停止输液,更换液体及输液管并报告医生,续输0.9% 氯化钠注射液100 ml,监测患者生命体征,患者无不良反应发生。
2 实验方法及结果为进一步证实注射用兰索拉唑与复方甘草酸单铵注射液是否存在配伍禁忌,随即我们做了配伍实验,用0.9% 氯化钠注射液10 ml 将注射用兰索拉唑30 mg 充分溶解取2 ml,与复方甘草酸单铵注射液2 ml 混合,随即出现白色浑浊现象,静置20 min 无变化,重复几次实验均出现相同的反应。
临床应用及实验均表明注射用兰索拉唑与复方甘草酸单铵注射液存在配伍禁忌,两者不能同时使用。
3 讨论经查阅《306 种注射剂临床配伍应用检索表》及药品说明书,未注明注射用兰索拉唑与脱氧核苷酸钠复方甘草酸单铵注射液存在配伍禁忌,因此,医护人员在临床中使用上述两种药物时,应间隔给药,可在两种药物输注间歇时用生理盐水冲洗输液管,减慢输液速度,观察患者的反应,避免两种药物直接接触而发生反应,给患者造成不良后果,确保临床用药安全。

O N H NS CH 2 N H 3C2CF 3 (No. 3954)PRV0509 R6May 2009PREVACID ® I.V.(lansoprazole)for Injection30 mg/vialR x onlyDESCRIPTIONThe active ingredient in PREVACID I.V. (lansoprazole) for Injection is a substituted benzimidazole, 2-[[[3-methyl-4-(2,2,2-trifluoroethoxy)-2-pyridyl] methyl] sulfinyl] benzimidazole, a compound that inhibits gastric acid secretion. Its empirical formula is C 16H 14F 3N 3O 2S with a molecular weight of 369.37. PREVACID has the following structure:Lansoprazole is a white to brownish-white odorless crystalline powder which melts withdecomposition at approximately 166°C. Lansoprazole is freely soluble in dimethylformamide; soluble in methanol; sparingly soluble in ethanol; slightly soluble in ethyl acetate, dichloromethane and acetonitrile; very slightly soluble in ether; and practically insoluble in hexane and water.Lansoprazole is stable when exposed to light for up to two months. The rate of degradation of the compound in aqueous solution increases with decreasing pH.PREVACID I.V. for Injection contains 30 mg of the active ingredient lansoprazole, 60 mgmannitol, 10 mg meglumine, and 3.45 mg sodium hydroxide and is supplied as a sterile, lyophilized powder for I.V. (intravenous) use. The solution of PREVACID I.V. for Injection has a pH ofapproximately 11 following the first reconstitution with Sterile Water for Injection, USP, andapproximately 10.2, 10.0, or 9.5 after further dilution with either 0.9% Sodium Chloride Injection, USP, Lactated Ringer’s Injection, USP, or 5% Dextrose Injection, USP, respectively.CLINICAL PHARMACOLOGYPharmacokinetics and MetabolismFollowing the administration of 30 mg of lansoprazole by intravenous infusion over 30 minutes to healthy subjects, plasma concentrations of lansoprazole declined exponentially with a mean (+ standard deviation) terminal elimination half-life of 1.3 (± 0.5) hours. The mean peak plasma concentration of lansoprazole (C max) was 1705 (± 292) ng/mL and the mean area under the plasma concentration versus time curve (AUC) was 3192 (± 1745) ng⋅h/mL. The absolute bioavailability of lansoprazole following oral administration is over 80%, and C max and AUC of lansoprazole are approximately proportional in doses from 15 mg to 60 mg after single oral administration. The pharmacokinetics of lansoprazole did not change with time after 7-day once daily repeated oral or intravenous administration of 30 mg lansoprazole.DistributionThe apparent volume of distribution of lansoprazole is approximately 15.7 (± 1.9) L, distributing mainly in extracellular fluid. Lansoprazole is 97% bound to plasma proteins. Plasma protein binding is constant over the concentration range of 0.05 to 5.0 µg/mL.MetabolismLansoprazole is extensively metabolized in the liver. Two metabolites have been identified in measurable quantities in plasma (the hydroxylated sulfinyl and sulfone derivatives of lansoprazole). These metabolites have very little or no antisecretory activity. Lansoprazole is thought to be transformed into two active species which inhibit acid secretion by blocking the proton pump [(H+,K+)-ATPase enzyme system] at the secretory surface of the gastric parietal cell. The two active species are not present in the systemic circulation. The plasma elimination half-life of lansoprazole is less than 2 hours while the acid inhibitory effect lasts more than 24 hours. Therefore, the plasma elimination half-life of lansoprazole does not reflect its duration of suppression of gastric acid secretion. EliminationFollowing an intravenous dose of lansoprazole, the mean clearance was 11.1 (± 3.8) L/h. Following single-dose oral administration of lansoprazole, virtually no unchanged lansoprazole was excreted in the urine. In one study, after a single oral dose of 14C-lansoprazole, approximately one-third of the administered radiation was excreted in the urine and two-thirds was recovered in the feces. This implies a significant biliary excretion of the lansoprazole metabolites.Special PopulationsGeriatric UseFollowing oral administration, the clearance of lansoprazole is decreased in the elderly, with elimination half-life increased approximately 50% to 100%. Because the mean half-life in the elderly remains between 1.9 to 2.9 hours, repeated once daily dosing does not result in accumulation of lansoprazole. Peak plasma levels were not increased in the elderly. No intravenous dosage adjustment is needed.Pediatric UseThe pharmacokinetics of intravenous lansoprazole have not been studied in pediatric patients. For further information, please see the PREVACID package insert for the oral formulations.GenderThe pharmacokinetic data of intravenous lansoprazole in females is limited; however, in a study with oral lansoprazole comparing 12 male and 6 female human subjects who received lansoprazole, no gender differences were found in pharmacokinetics and intragastric pH results. No intravenous dosage adjustment is needed (also refer to Use in Women).Renal InsufficiencyIn patients with severe renal insufficiency, plasma protein binding decreased by 1.0%-1.5% after oral administration of 60 mg of lansoprazole. Patients with renal insufficiency had a shortened elimination half-life and decreased total AUC (free and bound). The AUC for free lansoprazole in plasma, however, was not related to the degree of renal impairment; and the C max and T max (time to reach the maximum concentration) were not different than the C max and T max from subjects with normal renal function. No intravenous dosage adjustment is necessary in patients with renal insufficiency. Hepatic InsufficiencyIn patients with various degrees of chronic hepatic disease, the mean plasma half-life of lansoprazole was prolonged from 1.5 hours to 3.2-7.2 hours after oral administration. An increase in the mean AUC of up to 500% was observed at steady state in hepatically-impaired patients compared to healthy subjects. Intravenous dose reduction in patients with severe hepatic disease should be considered. RaceThe pooled mean pharmacokinetic parameters of orally administered lansoprazole from twelve U.S. Phase 1 studies (N=513) were compared to the mean pharmacokinetic parameters from two Asianstudies (N=20). The mean AUCs of lansoprazole in Asian subjects were approximately twice those seen in pooled U.S. data; however, the inter-individual variability was high. The C max values were comparable. Information for intravenous dosing is not available.PharmacodynamicsMechanism of ActionPREVACID (lansoprazole) belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the (H+, K+) -ATPase enzyme system at the secretory surface of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the parietal cell, lansoprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the final step of acid production. This effect is dose-related and leads to inhibition of both basal and stimulated gastric acid secretion for at least 24 hours irrespective of the stimulus. Lansoprazole does not exhibit anticholinergic or histamine type-2 antagonist activity.Antisecretory ActivityAcid OutputAn open-label, single-center, two period study was conducted to evaluate the pharmacodynamics of 30 mg of intravenous lansoprazole and 30 mg of oral lansoprazole in 29 healthy subjects. The primary pharmacodynamic endpoints were pentagastrin stimulated maximum acid output (MAO) and basal acid output (BAO). Subjects received oral lansoprazole for 7 days in Period 1 and then were immediately switched to intravenous lansoprazole for 7 days in Period 2. MAO and BAO were measured at baseline and 21 hours following the last oral dose and the last intravenous dose of lansoprazole. This study demonstrated that 7 days of oral lansoprazole followed by 7 days of intravenous lansoprazole administration significantly suppressed gastric acid output as compared with baseline. Seven days of 30 mg of intravenous lansoprazole was equivalent to 30 mg of oral lansoprazole in the ability to maintain gastric acid output suppression (Table 1).Table 1: Acid Output (mEq/hr)PREVACID 30 mgBaseline After 7 Days ofOral Dosing After 7 Days of I.V. DosingMaximum Acid Output (Median) 11.26n=27 4.76*n=285.13*n=28Basal Acid Output (Median) 1.42n=28 0.42*n=280.27*n=28* Significantly (p ≤ 0.05) less acid output as compared to baseline.24-Hour Intragastric pHA multiple-dose study was conducted in 36 healthy subjects comparing the pharmacokinetics and pharmacodynamics of lansoprazole after intravenous administration and oral administration. During the first-hour post-dosing interval, intravenous lansoprazole resulted in significantly higher mean intragastric pH than did oral lansoprazole. There were no statistically significant differences between oral and intravenous regimens in 24-hour mean intragastric pH for the percentage of time that the intragastric pH was above 3 and 4 after 1-day or 5-day once daily repeated administration of 30 mg lansoprazole. Gastric acid suppression was maintained throughout each treatment period. The pharmacodynamic results are summarized in Table 2.Table 2: Mean Antisecretory Effects after Single and Multiple Daily DosingParameter BaselineValuePREVACID30 mg daily Orallyx 5 days30 mg I.V.

Longer term data are needed to rule out the possibility of an increased risk of the development of gastric tumors in patients receiving long-term therapy with lansoprazole. Other Gastric Effects In HumansLansoprazole did not significantly affect mucosal blood flow in the fundus of the stomach. Due to the normal physiologic effect caused by the inhibition of gastric acid secretion, a decrease of about 17% in blood flow in the antrum, pylorus, and duodenal bulb was seen. Lansoprazole significantly slowed the gastric emptying of digestible solids. Lansoprazole increased serum pepsinogen levels and decreased pepsin activity under basal conditions and in response to meal stimulation or insulin injection. As with other agents that elevate intragastric pH, increases in gastric pH were associated with increases in nitrate-reducing bacteria and elevation of nitrite concentration in gastric juice in patients with gastric ulcer. No significant increase in nitrosamine concentrations was observed.Serum Gastrin EffectsIn over 2,100 patients, median fasting serum gastrin levels increased 50% to 100% from baseline but remained within normal range after treatment with 15 to 60 mg of oral lansoprazole. These elevations reached a plateau within two months of therapy and returned to pretreatment levels within four weeks after discontinuation of therapy.Endocrine EffectsHuman studies for up to one year have not detected any clinically significant effects on the endocrine system. Hormones studied include testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH), sex hormone binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEA-S), prolactin, cortisol, estradiol, insulin, aldosterone, parathormone, glucagon, thyroid stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), and somatotropic hormone (STH). Lansoprazole in oral doses of 15 to 60 mg for up to one year had no clinically significant effect on sexual function. In addition, lansoprazole in oral doses of 15 to 60 mg for two to eight weeks had no clinically significant effect on thyroid function.In 24-month carcinogenicity studies in Sprague-Dawley rats with daily lansoprazole dosages up to 150 mg/kg, proliferative changes in the Leydig cells of the testes, including benign neoplasm, were increased compared to control rates; these findings are rat specific.Other EffectsNo systemic effects of lansoprazole on the central nervous system, lymphoid, hematopoietic, renal, hepatic, cardiovascular or respiratory systems have been found in humans. Among 56 patients who had extensive baseline eye evaluations, no visual toxicity was observed after lansoprazole treatment (up to 180 mg/day) for up to 58 months.After lifetime lansoprazole exposure in rats, focal pancreatic atrophy, diffuse lymphoid hyperplasia in the thymus and spontaneous retinal atrophy were seen.CLINICAL STUDIESErosive EsophagitisA multicenter, double-blind, two-period placebo-controlled, pharmacodynamic study was conductedto assess the ability of PREVACID I.V. for Injection to maintain gastric acid suppression in patients switched from the oral dosage form of lansoprazole to the intravenous dosage form. Erosive esophagitis patients (n=87; 18 to 78 years of age; 28 female; 69 Caucasian/non-Hispanic, 14 Hispanic, 3 African-American, and 1 Native American) received 30 mg of oral lansoprazole for 7 days in Period 1. Patients were then immediately switched to receive either 30 mg of intravenous lansoprazole or intravenous placebo (normal saline) for 7 days in Period 2. MAO and BAO were determined 21 hours following the last dose of oral medication and the last dose of intravenous administration. MAO was calculated from two hours of continuous collection of gastric contents following a subcutaneous injection of 6.0 μg/kg of pentagastrin. BAO was calculated from one hour of continuous collection of gastric contents.This study demonstrated that, after seven days of repeated oral administration followed by 7 days of intravenous administration, the oral and intravenous dosage forms of PREVACID were similar in their ability to suppress MAO and BAO in patients with erosive esophagitis (refer to Table 3). Also, patients receiving oral PREVACID, who were switched to intravenous placebo, experienced a significant increase in acid output within 48 hours of their last oral dose.Table 3: Acid Output (mEq/h) in Erosive Esophagitis PatientsPREVACID Oral PREVACID I.V.

Once the patient is able to take medications orally, therapy can be switched to an oral formulation of PREVACID for a total of 6 to 8 weeks. The safety and efficacy of PREVACID I.V. for Injection as an initial treatment of erosive esophagitis have not been demonstrated. Refer to full prescribing information for the oral formulations of PREVACID.CONTRAINDICATIONSPREVACID I.V. for Injection is contraindicated in patients with known severe hypersensitivity to any component of the formulation.PRECAUTIONSGeneralSymptomatic response to therapy with lansoprazole does not preclude the presence of gastric malignancy.Treatment with PREVACID I.V. for Injection should be discontinued as soon as the patient is able to resume treatment with PREVACID oral formulations.Drug InteractionsLansoprazole is metabolized through the cytochrome P450 system, specifically through the CYP3A and CYP2C19 isozymes. Studies have shown that lansoprazole does not have clinically significant interactions with other drugs metabolized by the cytochrome P450 system, such as warfarin, antipyrine, indomethacin, ibuprofen, phenytoin, propranolol, prednisone, diazepam, or clarithromycin in healthy subjects. These compounds are metabolized through various cytochrome P450 isozymes including CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A. When lansoprazole was administered concomitantly with theophylline (CYP1A2, CYP3A), a minor increase (10%) in the clearance of theophylline was seen. Because of the small magnitude and the direction of the effect on theophylline clearance, this interaction is unlikely to be of clinical concern. Nonetheless, individual patients may require additional titration of their theophylline dosage when lansoprazole is started or stopped to ensure clinically effective blood levels.In a study of healthy subjects neither the pharmacokinetics of warfarin enantiomers nor prothrombin time were affected following single or multiple 60 mg doses of lansoprazole. However, there have been reports of increased International Normalized Ratio (INR) and prothrombin time in patients receiving proton pump inhibitors, including lansoprazole, and warfarin concomitantly. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Patients treated with proton pump inhibitors and warfarin concomitantly may need to be monitored for increases in INR and prothrombin time.Concomitant administration of lansoprazole and tacrolimus may increase whole blood levels of tacrolimus, especially in transplant patients who are intermediate or poor metabolizers of CYP2C19.Lansoprazole causes a profound and long-lasting inhibition of gastric acid secretion; therefore, it is theoretically possible that lansoprazole may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (eg, ketoconazole, ampicillin esters, iron salts, digoxin). Carcinogenesis, Mutagenesis, Impairment of FertilityIn two 24-month carcinogenicity studies, Sprague-Dawley rats were treated with oral lansoprazole doses of 5 to 150 mg/kg/day - about 1 to 40 times the exposure on a body surface (mg/m2) basis of a 50-kg person of average height [1.46 m2 body surface area (BSA)] given the recommended human dose of 30 mg/day. Lansoprazole produced dose-related gastric enterochromaffin-like (ECL) cell hyperplasia and ECL cell carcinoids in both male and female rats. It also increased the incidence of intestinal metaplasia of the gastric epithelium in both sexes. In male rats, lansoprazole produced a dose-related increase of testicular interstitial cell adenomas. The incidence of these adenomas in rats receiving doses of 15 to 150 mg/kg/day (4 to 40 times the recommended human dose based on BSA) exceeded the low background incidence (range = 1.4 to 10%) for this strain of rat.In a 24-month carcinogenicity study, CD-1 mice were treated orally with doses of 15 to600 mg/kg/day, 2 to 80 times the recommended human dose based on BSA. Lansoprazole produced a dose-related increased incidence of gastric ECL cell hyperplasia. It also produced an increased incidence of liver tumors (hepatocellular adenoma plus carcinoma). The tumor incidences in male mice treated with 300 and 600 mg/kg/day (40 to 80 times the recommended human dose based on BSA) and female mice treated with 150 to 600 mg/kg/day (20 to 80 times the recommended human dose based on BSA) exceeded the ranges of background incidences in historical controls for this strainof mice. Lansoprazole treatment produced adenoma of rete testis in male mice receiving 75 to600 mg/kg/day (10 to 80 times the recommended human dose based on BSA).A 26-week p53 (+/-) transgenic mouse carcinogenicity study was not positive.Lansoprazole was not genotoxic in the Ames test, the ex vivo rat hepatocyte unscheduled DNA synthesis (UDS) test, the in vivo mouse micronucleus test, or the rat bone marrow cell chromosomal aberration test. It was positive in in vitro human lymphocyte chromosomal aberration assays.Lansoprazole at intravenous doses of up to 30 mg/kg/day (approximately 8 times the recommended human dose based on BSA) was found to have no effect on fertility and reproductive performance in male and female rats.Pregnancy: Teratogenic EffectsPregnancy Category BTeratology studies have been conducted in rats and rabbits using intravenous lansoprazole doses of up to 30 mg/kg/day (approximately 8 times in rats and 16 times in rabbits of the recommended human dose based on BSA). Treatment with lansoprazole did not result in any impairment of fertility or harm to the fetus.However, there are no adequate and well-controlled studies in pregnant women using the intravenous route. Because animal reproduction studies are not always predicative of human response, PREVACID I.V. for Injection should be used during pregnancy only if clearly needed.Nursing MothersLansoprazole or its metabolites are excreted in the milk of rats. It is not known whether lansoprazole is excreted in human milk. Because many drugs are excreted in human milk, because of the potential for serious adverse reactions in nursing infants from lansoprazole, and because of the potential for tumorigenicity shown for lansoprazole in rodent carcinogenicity studies, a decision should be made whether to discontinue nursing or to discontinue PREVACID I.V. for Injection, taking into accountthe importance of PREVACID I.V. for Injection to the mother.Pediatric UseThe safety and effectiveness of PREVACID I.V. for Injection have not been established for pediatric patients. For further information, please see the PREVACID package insert for the oral formulations.Use in WomenAmong intravenous PREVACID treated subjects, similar percentages of adverse events were reported in males and females.Over 4,000 women were treated with oral PREVACID. Ulcer healing rates in females were similar to those in males. The incidence rates of adverse events in females were also similar to those seen in males.Use in Geriatric PatientsData in elderly patients administered intravenous lansoprazole is limited; however, with oral lansoprazole, ulcer healing rates in elderly patients are similar to those in a younger age group. The incidence rates of PREVACID-associated adverse events and laboratory test abnormalities are similar to those seen in younger patients. For geriatric patients, dosage and administration of PREVACID need not be altered for a particular indication.ADVERSE REACTIONSClinical Safety Experience with PREVACID I.V. for InjectionMore than 1,000 patients and subjects have participated in domestic and foreign clinical trials. Treatment with PREVACID I.V. for Injection was well-tolerated.In four U.S. trials involving 161 subjects exposed to PREVACID I.V. for Injection, the following treatment-related adverse events were reported in >1% of subjects: headache (1.0%), injection site pain (1.0%), injection site reaction (1.0%) and nausea (1.3%). Treatment-related adverse events occurring in less than 1% of subjects included abdominal pain, vasodilatation, diarrhea, dyspepsia, vomiting, dizziness, paresthesia, rash, and taste perversion. No additional adverse drug reactions were reported with the intravenous formulation that had not been reported previously with the oral formulations.Clinical Safety Experience with Oral Formulations of PREVACIDWorldwide, over 10,000 patients have been treated with oral PREVACID in Phase 2 or Phase3 clinical trials involving various dosages and durations of treatment. In general, PREVACID treatment has been well-tolerated in both short-term and long-term trials.The following adverse events were reported by the treating physician to have a possible or probable relationship to drug in 1% or more of PREVACID-treated patients and occurred at a greater rate in PREVACID-treated patients than placebo-treated patients in Table 4.Table 4: Incidence of Possibly or Probably Treatment-Related Adverse Events in Short-Term,Placebo-Controlled PREVACID StudiesBody System/Adverse Event PREVACIDOral(N= 2768)%Placebo(N= 1023)%Body as a WholeAbdominal Pain Digestive SystemConstipation DiarrheaNausea 2.11.03.81.31.20.42.31.2Headache was also seen at greater than 1% incidence but was more common on placebo.

注射用兰索拉唑的研究
注射用兰索拉唑的研究注射用兰索拉唑的研究引言:兰索拉唑是一种广泛应用于临床上的质子泵抑制剂,可用于治疗与胃酸相关的疾病,包括胃溃疡、食管反流、消化性溃疡等。
而注射用兰索拉唑近年来也逐渐受到关注和研究。
本文将从注射用兰索拉唑的用途、疗效以及不良反应进行综述。
一、注射用兰索拉唑的用途注射用兰索拉唑主要用于以下情况:1. 治疗非吻合性胃炎、胃溃疡和保胃大静脉或胃大后静脉出血。
2. 放疗和化疗引起的放射性或化学性食道炎。
3. 高危患者的急性上消化道出血的二次预防。
4. 危重症患者中的消化性溃疡出血预防。
二、注射用兰索拉唑的疗效注射用兰索拉唑主要通过抑制胃酸分泌来发挥其作用。
研究表明,注射用兰索拉唑能有效地控制胃内酸度,减少胃酸的刺激对胃黏膜的损害,并具有良好的治疗效果。
例如,在治疗急性上消化道出血方面,注射用兰索拉唑能够迅速减少出血量,控制出血源,并且有助于胃黏膜的愈合与修复。
此外,注射用兰索拉唑也可以显著减少食道炎症,缓解患者的症状。
三、注射用兰索拉唑的不良反应注射用兰索拉唑不良反应的发生率相对较低,但还是需要注意以下几点:1. 皮疹和过敏反应:少数患者可能出现皮疹、瘙痒等过敏反应。
对于对质子泵抑制剂过敏的患者,应避免使用注射用兰索拉唑。
2. 消化系统反应:部分患者可能在使用注射用兰索拉唑后出现恶心、呕吐等消化系统反应,但发生率较低。
3. 肝功能异常:极少数患者在使用注射用兰索拉唑后可能出现肝功能异常,但与剂量相关性不明确。
四、新进展和研究方向近年来,注射用兰索拉唑的研究也在不断深入。
一方面,研究者通过各类临床试验,探索注射用兰索拉唑在更广泛临床领域的应用,例如胃癌术后出血、胃泌素瘤等相关疾病治疗方面的应用潜力。
另一方面,也出现了越来越多的关于质子泵抑制剂使用安全性的争议。
有研究表明,长期使用质子泵抑制剂可能与骨质疏松、维生素B12缺乏、感染风险增加等不良反应有关。
因此,关于注射用兰索拉唑的长期使用和不良反应的研究依然具有重要意义。
