Overview
Cisapride is a gastrointestinal pro-motility drug, and was listed in the UK in 1988. It is a benzamide compound without anti-dopaminergic properties and does not have direct cholinergic properties. Its mechanism of action is different from that of metoclopramide and domperidone. It does not affect dopamine receptors, instead acts through acting with different serotonin receptors on the parietal plexus ending of the posterior wall of gastrointestinal organ, promoting the release of wall muscle acetylcholine (in quantity and time), further stimulating the entire digestive system organs and exerting an pro-motility effect. It does not affect the submucosal plexus, does not change the secretion of mucous membranes, belonging to a driving force drugs. This product can enhance the contraction and peristalsis of the human esophagus, stomach and duodenum, further improving the coordination of gastric antral duodenal region and preventing gastroesophageal and duodenal reflux. It can strengthen the emptying of the stomach and duodenum, and can promote the peristalsis of the large intestine and small intestine. It is mainly used for the treatment of gastrointestinal motility disorders, such as functional dyspepsia, gastroesophageal reflux disease, chronic constipation, bile reflux gastritis, neonatal vomiting and non-ulcer dyspepsia. Second, it can also be used for the treatment of non-gastrointestinal motility disorders, such as diabetic neurogenic bladder, gallbladder contraction disorders.
Mechanism of Action
This product belongs to the whole gastrointestinal pro-motility drug. It can strengthen and coordinate gastrointestinal motility, further preventing food retention and reflux. Its mechanism of action is mainly through the selective promotion of the release of acetylcholine in the intestinal myenteric plexus postganglionic nerve, thereby enhancing gastrointestinal motility. Animal experiments confirmed that this product can accelerate the gastric motility, enhance the gastrointestinal - duodenal digestive activity, coordinate the action of gastric antrum - duodenum, small intestine and large intestine, and reduce intestinal movement time. In the human body, this product can enhance esophageal peristalsis, increase the tension of the lower esophageal sphincter to prevent the reflux of gastric contents into the esophagus and improve esophageal clearance; can enhance the contraction of stomach and duodenum and improve the gastric antrum – duodenum coordination. This effect can prevent duodenal - gastric reflux, promote gastric and duodenal emptying; promote small intestine and colon peristalsis.
This product does not affect the gastrointestinal submucosal plexus, it does not change the secretion of gastrointestinal mucosa. At the same time because this product does not inhibit the activity of acetylcholinesterase, nor has dopamine receptor blocking effect, it does not increase gastric acid secretion; does not affect the level of plasma prolactin. Therefore, it basically has no central inhibitory effect.
Pharmacokinetics
Oral administration leads to rapid absorption with plasma concentration reaching peak within 1 ~ 2h; protein binding rate: 98%; bioavailability: 40% to 50%; half-life:7 ~ 10h. It is subject to metabolism inside the body to demethylated cisapride. 90% is excreted through the urine with a small amount subjecting to milk excretion.
Indications
Different sources of media describe the Indications of 81098-60-4 differently. You can refer to the following data:
1. It is mainly used for the treatment of functional dyspepsia, relieving abdominal fullness, fullness, nausea, vomiting, belching, abdominal pain and other symptoms.

Drug Interactions
Combinations with drugs that prolong the QT interval such as Class Ia antiarrhythmic drugs (such as quinidine, disopyramide and procainamide), class III antiarrhythmic drugs (such as amiodarone, sotalol), tricyclic antidepressants (such as amitriptyline), tetracycline antidepressants (such as maprotiline), antipsychotics (such as phenothiazine, pimozide), anti-histamine drugs (such as Astemizole, Tefinatide), bepupi and halofantrine can increase the cardiotoxicity, so this good should be banned for combination with these drugs.
Drug inhibiting the CYP3A4 enzyme such as nefazodone, azoles antifungal drugs (such as ketoconazole, itraconazole, miconazole, fluconazole), macrolide antibiotics (such as erythromycin , Clarithromycin, Troleandomycin), protease inhibitors (such as indinavir, ritonavir, amprenavir) can inhibit the metabolism of the goods, increased blood concentration and cause cardiotoxicity ( Such as QT prolongation, torsades de pointes ventricular tachycardia, ventricular fibrillation, cardiac arrest, etc.), so the treatment of these goods should be prohibited during taking cisapride.
Cimetidine can increase the blood concentration of this product, but with no clinical significance.
Combination with bromipeline and haloperidol can promote the absorption of the latter, inhibiting its metabolism, so that mental symptoms are worsened.
Combination with cyclosporine can increase the latter's absorption rate, enhance its toxicity (such as renal dysfunction, cholestasis, etc.).
This product can accelerate the absorption of central nervous inhibitory drugs (such as barbiturates).
This product can reduce the metabolism of tacrolimus, increasing its risk of causing adverse reactions (such as toxic renal damage, hyperglycemia and hyperkalemia).
Combination with levodopa can increase the risk of the adverse reactions (such as involuntary movement, tremors, nausea and vomiting and cardiovascular irritation) caused by latter one.
This product can accelerate gastric emptying, thereby reducing the rate of absorption of drugs to be absorbed through the stomach; on the contrary, it may increase the absorption rate of drugs absorbed by the intestine (such as anticoagulants, acetaminophen, H2 receptor antagonists, etc.) Absorption rate. When combined with anticoagulants, it can extend the clotting time. In this case, pay attention to check the clotting time to determine the appropriate dose of anticoagulant.
Anticholinergic drugs (such as atropine, benztropine and belladonna preparations) can reduce the efficacy of this product.
This product can reduce the absorption of digoxin, but have no clinical significance.

Definition
ChEBI: The amide resulting from formal condensation of 4-amino-5-chloro-2-methoxybenzoic acid with cis-1-[3-(4-fluorophenoxy)propyl]-3-methoxypiperidin-4-amine. It has been used (as its monohydrate or as its tartrate) for the treatment of gastro-oeso
hageal reflux disease and for non-ulcer dyspepsia, but its propensity to cause cardiac arrhythmias resulted in its complete withdrawal from many countries, including the U.K., and restrictions on its use elsewhere.
Manufacturing Process
A mixture of 1-[3-(4-fluorophenoxy)-propyl]-3-methoxy-4-piperidinone (140
mg), benzylamine (61 mg), Pd 10% on charcoal (100 mg) and a 0.02%
solution of thiophene in THF was reacted under hydrogen gas for 3 hours at
50°C. The catalyst was filtered off and fresh palladium 10% on charcoal (100
mg) was added. Debenzylation of the formed intermediate took place under
hydrogen atmosphere for 18 hours at 50°C. The reaction mixture was filtered
and evaporated under a stream of nitrogen to yield 1-[3-(4-fluorophenoxy)-
propyl]-3-methoxy-4-piperidinamine having a cis/trans ratio of about 93/7.
1-[3-(4-Fluorophenoxy)-propyl]-3-methoxy-4-piperidinamine (50 g) was
dissolved in methyl isobutylketone (250 ml) and a nitric acid solution (65%,
12.8 ml) was carefully added so that the temperature of the solution did not
exceed 45°C. The reaction mixture was stirred at a temperature of 30°C and
seeded. When crystallisation started, the reaction mixture was cooled to 0°C
and stirred for another 2 hours. The product was filtered off, washed with a
small amount of toluene and dried, yielding 1-[3-(4-fluorophenoxy)-propyl]-3-
methoxy-4-piperidinamine nitrate (m.p. 60°C).
1-[3-(4-Fluorophenoxy)-propyl]-3-methoxy-4-piperidinamine nitrate was
dissolved in water (95 ml). The reaction mixture was stirred and toluene (95
ml) was added. A NaOH solution (50%, 10.3 ml) was slowly added and the
temperature of the reaction mixture was raised to 75°C. After 30 min, the
aqueous layer was discarded and the organic layer was evaporated, yielding
1-[3-(4-fluorophenoxy)-propyl]-3-methoxy-4-piperidinamine having a
cis/trans ratio equal to or higher than 98/2.
To a solution of 4-amino-5-chloro-2-methoxybenzoic acid (20.2 g) in methyl
isobutylketone (250 ml) and triethyl amine (15.3 ml) was slowly dropped
ethyl chloroformate (9.6 ml). The reaction mixture was stirred for 30 min at
room temperature. To the formed mixed anhydride was then added 1-[3-(4-
fluorophenoxy)-propyl]-3-methoxy-4-piperidinamine (28.2 g) and the reaction
mixture was stirred for 2 hours at room temperature. Subsequently, the
reaction mixture was washed with water (80 ml) and a NaOH solution (6.5%
w/v, 50 ml). The organic layer was warmed to 65°C and methanol (50 ml)
and water (8.5 ml) were added. The solution was cooled slowly and stirred for
2 days during which crystallisation occurred, yielding benzamide, 4-amino-5-
chloro-N-(1-(3-(4-fluorophenoxy)propyl)-3-methoxy-4-piperidinyl)-2-methoxy-
, monohydrate, cis- (Cisapride) having a cis/trans ratio higher than 99/1.
Brand name
Propulsid (Janssen);Calmax;Cisapid;Cismotil;Digenol;Prepulsid.
Biological Activity
5-HT 4 receptor agonist and gastrokinetic agent. Stimulates intestinal acetylcholine release, possibly via 5-HT 4 receptor-dependent and -independent mechanisms, leading to increased intestinal motility.
Clinical Use
Cisapride has been successfully used to treat
gastroparesis and mild gastroesophageal reflux disease.
Side effects
The most frequent side effect has been diarrhea. A few
patients had seizure activity that was reversible after
medication was discontinued. Cisapride was pulled
from the U. S. market after deaths from drug-associated
cardiac arrhythmias, including ventricular tachycardia,
ventricular fibrillation, torsades de pointes, and QT prolongation.
Veterinary Drugs and Treatments
Proposed uses for cisapride in small animals includes esophageal
reflux and treatment
of primary gastric stasis disorders. Cisapride
has been found to be useful in the treatment of constipation and
megacolon in cats.
Metabolic pathway
Cisapride 14C labeled at the carbonyl carbon and 3H
labeled at the fluorophenyl moiety or at the piperidine
ring is investigated using some animals. N-
Dealkylation at the nitrogen of the piperidine ring,
resulting in the main urinary metabolite norcisapride,
and aromatic hydroxylation of the fluorinated phenyl
ring are the major metabolic pathways in dogs and
humans. Norcisapride excretion accounts for 14% of
the dose in dogs and 41-45% in humans. Minor
metabolic pathways are O-dearylation of the 4-
fluorophenyl group and oxidation on the piperidine ring
(rat, rabbits and dogs: Lavrijsen et al. (1986)15).

A concise asymmetric synthesis of the gastroprokinetic agent (+)-(3S,4R)-cisapride {(+)-(3S,4R)-N(1)-[3′-(4″-fluorophenoxy) propyl]-3-methoxy-4-(2″′-methoxy-4″′-amino- 5″′-chlorobenzamido)piperidine} from commercially available starting materials has been developed. The key step of this synthesis employs the diastereoselective conjugate addition of lithium (R)-N-benzyl-N-(α- methylbenzyl)amide to tert-butyl 5-[N-3′-(4″-fluorophenoxy)propyl-N- allylamino]pent-2-enoate and in situ enolate oxidation with (-)- camphorsulfonyloxaziridine to set the (3S,4R)-configuration found within the piperidine ring of the product. This synthesis proceeds in 9 steps from commercially available 1-(4′-fluorophenoxy)-3-bromopropane with an overall yield of 19%.
