A precise and reliable reversed-phase high-performance liquid chromatographic method with ultraviolet detection was developed and validated to determine cinitapride in human plasma. After liquid-liquid extraction, chromatographic separation was achieved on a Nucleosil C18 (25 cm × 4.6 mm, 5  µ m) column with an isocratic elution consisting of 10 mM ammonium acetate (pH 5.2), methanol, and acetonitrile, 40 : 50 : 10, v/v/v. The developed method was validated as per US FDA guidelines for its linearity, selectivity, sensitivity, precision, accuracy, and stability...

The initiation of newer techniques and development of mouth dissolving (MD) products has created new avenues of higher patients' compliance. MD formulations are actually lessen the difficulties associated with solid swallowing with better bioavailability of especially poorly soluble drugs. In the current study mouth dissolving tablet (MDT) formulations of cinitapride (1 mg) were prepared by direct compression method using various proportion and combination of superdisintegrants. Nine formulations in three batches were compressed by incorporating low (2%), intermediate (6%) and higher (10%) levels of crospovidone, croscarmellose sodium, sodium starch glycolate...

Cinitapride (CIN) is a drug for functional dyspepsia. The purpose of the study was to investigate the pharmacokinetics and tolerability of CIN in healthy Chinese volunteers. A randomized, open-label, single- and multiple-dose study was conducted in 12 healthy volunteers. Three different doses of CIN (1, 2, 4 tablets) were given to six groups in the single-dose study, and one tablet (1 mg) of CIN was administered three times a day in the multiple-dose study. Blood samples were collected at predetermined time intervals after CIN dosing and analyzed by LC-MS/MS...

A simple stability indicating UV-spectrophotometric method has been developed and validated for the determination of cinitapride hydrogen tartrate (CHT) in bulk and solid pharmaceutical dosage form. Drug absorption was measured in different analytical mediums however; maximum absorption was seen in 0.1 N HCl at wavelength (λmax) of 266 nm. The calibration curve was found to be linear over the concentration range from 6 to14μg/mL with the correlation coefficient value (r) of 0.999. The LOD and LOQ were estimated to be 0...

AIM: Cinitapride (CIN) is a benzamide-derived molecule used for the treatment of gastroesophageal reflux and dyspepsia. Its pharmacokinetics are controversial due to the use of supratherapeutic doses and the lack of sensitive methodology. Therefore, a sensitive and accurate micromethod was developed for its quantitation in human plasma. RESULTS: CIN was extracted from 300 µl of heparinized plasma by liquid-liquid extraction using cisapride as internal standard, and analyzed with an ultra performance liquid chromatograph employing positive multiple-reaction monitoring-MS...

Little is known about the clinical efficacy of cinitapride, a 5-HT₄ agonist and D₂ antagonist, in treating FD. STUDY: This randomized, double-blind, double-dummy, positive-controlled study compared the efficacy and safety of cinitapride (1 mg) and domperidone (10 mg) tid for 4 weeks in 383 consecutive patients with mild to moderate, postprandial distress syndrome-predominant dyspeptic symptoms according to Rome III criteria...

An ultra-high performance liquid chromatographic method has been utilized to obtain metabolic profiles of cinitapride with liver microsomes of humans and various mammal species such as rats, mice, mini pigs, dogs, and monkeys. Metabolites have been generated by incubation of cinitapride in the presence of microsomes using nicotinamide adenine dinucleotide phosphate as a cofactor. Incubation times from 15 to 60 min have been assayed. Cinitapride and its metabolites have been separated by reversed-phase C(18) mode using ammonium formate aqueous solution (pH 6...

An ultra high-performance liquid chromatographic method was developed to study the cinitapride metabolism. Metabolites were generated from the incubation of cinitapride with human liver microsomes. Cinitapride and its metabolites were separated by reversed-phase mode using a formate aqueous solution (pH 6.5) and acetonitrile as the components of the mobile phase. Chromatographic conditions, including the establishment of an elution gradient, were optimized for obtaining the maximum number of resolved components in the minimum analysis time...

INTRODUCTION: The sleep-related painful erection (SRPE) is a well-established parasomnia characterized by episodes of penile pain during an erection and typically appears during REM sleep. It is associated with nocturnal awakenings, anxiety, and irritability. AIM: To report a case study that highlights the successful treatment of SRPE with cinitapride. METHODS: We present a case report of a 50-year-old man suffering from SRPE that was studied by polysomnography...

INTRODUCTION AND OBJECTIVE: Functional dyspepsia is a highly common disorder. The physiopathological mechanisms of this entity are not yet completely known and prokinetic drugs seem to be useful. The aim of this study was to evaluate the prokinetic effect of cinitapride in patients with dysmotility-like dyspepsia and delayed gastric emptying. METHODS: Nineteen patients were randomized to receive 1mg of an oral solution of cinitapride t.i.d or placebo for 4 weeks in two consecutive periods, following a crossover and double-blind design...

Granulomatous interstitial nephritides are uncommon entities in routine clinical practice. These entities are usually associated with infectious diseases such as tuberculosis, or immune diseases, such as sarcoidosis, systemic lupus erythematosus or cryoglobulinemia. However, these diseases are most frequently associated with drug intake, especially antibiotics, proton pump inhibitors and nonsteroidal anti inflammatory drugs. An association with prokinetic agents has not previously been reported. We report the case of a 64-year-old woman who developed acute renal failure with this histological pattern after taking the motility promoter cinitapride without her physician's knowledge...

The present clinical trial was designed to evaluate the possible pharmacokinetic and electrocardiographic interactions of the gastroenteric prokinetic drug cinitapride with ketoconazole. The safety and tolerability of the study treatments were also evaluated. After a placebo-controlled, double-blind, crossover design, 16 healthy male (n = 8) and female (n = 8) volunteers were randomized into four treatment groups of four subjects (two males and two females): cinitapride (CTP; 1 mg t.i.d.) + ketoconazole (KET; 200 mg b...

Esophageal compression by a vascular structure is a rare cause of dysphagia, the aberrant right subclavian artery being the most common congenital abnormality. Aortica dysphagia is usually observed in the elderly, especially in hypertensive women with cardiopathy and degenerative osteopathy. We report a 73-year-old woman with dysphagia, caused by a non-aneurysmatic aortic elongation, who presented progressive dysphagia, which ended in aphagia associated with heart failure. The diagnostic approach to these patients is discussed...

This study was designed to determine the gastroprotective properties of cinitapride (CNT), a novel prokinetic benzamide derivative agonist of 5-HT4 and 5-HT1 receptors and 5-HT2 antagonist, on mucosal injury produced by 50% (v/v) ethanol. Results were compared with those for 5-hydroxytryptamine (5-HT: 10 mg kg-1). The possible involvements of gastric mucus secretion, endogenous prostaglandins (PGs) and sulfhydryl compounds (SH) in the protection mediated by CNT were also examined. Intraperitoneal administration of CNT (0...

In 20 patients with diagnosis of functional dyspepsia due to dysmotility and/or reflux, the effectivity and tolerance of two prokinetic drugs--metochlopramide (MCP) (10 mg. three daily doses, vo) and cinitrapide (CTP) (1 mg., 3 daily doses, vo)--were assessed using a protocol of a propective and cross-sectional study after a blank period. Following the treatment with MCP and CTP, statistically significant improvements were observed in the intensity/severity of postprandial epigastric fullness, flatulence, epigastralgia, pyrosis, active regurgitations and anorexia...
