Prucalopride (brand name Resolor, developed by Johnson & Johnson and licensed to Movetis) is a drug acting as a selective, high affinity 5-HT4 receptor agonist[1] which targets the impaired motility associated with chronic constipation, thus normalizing bowel movements.[2][3][4][5][6][7] Prucalopride was approved for use in Europe in 2009,[8] in Canada (named Resotran) on December 7, 2011[9] and in Israel in 2014[10] but it has not been approved by the Food and Drug Administration for use in the United States. The drug has also been tested for the treatment of chronic intestinal pseudo-obstruction.[11][12]
Mechanism of action
Prucalopride, a first in class dihydro-benzofuran-carboxamide, is a selective, high affinity serotonin (5-HT4) receptor agonist with enterokinetic activities.[13] Prucalopride alters colonic motility patterns via serotonin 5-HT4 receptor stimulation: it stimulates colonic mass movements, which provide the main propulsive force for defecation.
The observed effects are exerted via highly selective action on 5-HT4 receptors:[13] prucalopride has >150-fold higher affinity for 5-HT4 receptors than for other receptors.[1][14] Prucalopride differs from other 5-HT4 agonists such as tegaserod and cisapride, which at therapeutic concentrations also interact with other receptors (5-HT1B/D and the cardiac human ether-a-go-go K+ or hERG channelrespectively) and this may account for the adverse cardiovascular events that have resulted in the restricted availability of these drugs.[14] Clinical trials evaluating the effect of prucalopride on QT interval and related adverse events have not demonstrated significant differences compared with placebo.[13]
Pharmacokinetics
Prucalopride is rapidly absorbed (Cmax attained 2–3 hours after single 2 mg oral dose) and is extensively distributed. Metabolism is not the major route of elimination. In vitro, human liver metabolism is very slow and only minor amounts of metabolites are found. A large fraction of the active substance is excreted unchanged (about 60% of the administered dose in urine and at least 6% in feces).Renal excretion of unchanged prucalopride involves both passive filtration and active secretion. Plasma clearance averages 317 ml/min, terminal half-life is 24–30 hours,[15] and steady-state is reached within 3–4 days. On once daily treatment with 2 mg prucalopride, steady-state plasma concentrations fluctuate between trough and peak values of 2.5 and 7 ng/ml, respectively.[13]
In vitro data indicate that prucalopride has a low interaction potential, and therapeutic concentrations of prucalopride are not expected to affect the CYP-mediated metabolism of co-medicated medicinal products.[13]
Efficacy
The primary measure of efficacy in the clinical trials is three or more spontaneous complete bowel movements per week; a secondary measure is an increase of at least one complete spontaneous bowel movement per week.[7][16][17] Further measures are improvements in PAC-QOL[18] (a quality of life measure) and PAC-SYM[19] (a range of stool,abdominal, and rectal symptoms associated with chronic constipation). Infrequent bowel movements, bloating, straining, abdominal pain, and defecation urge with inability to evacuate can be severe symptoms, significantly affecting quality of life.[20][21][22][23][24]
In three large clinical trials, 12 weeks of treatment with prucalopride 2 and 4 mg/day resulted in a significantly higher proportion of patients reaching the primary efficacy endpoint of an average of ≥3 spontaneous complete bowel movements than with placebo.[7][16][17] There was also significantly improved bowel habit and associated symptoms, patient satisfaction with bowel habit and treatment, and HR-QOL in patients with severe chronic constipation, including those who did not experience adequate relief with prior therapies (>80% of the trial participants).[7][16][17] The improvement in patient satisfaction with bowel habit and treatment was maintained during treatment for up to 24 months; prucalopride therapy was generally well tolerated.[25][26]
Side effects
Prucalopride has been given orally to ~2700 patients with chronic constipation in controlled clinical trials. The most frequently reported side effects are headache andgastrointestinal symptoms (abdominal pain, nausea or diarrhea). Such reactions occur predominantly at the start of therapy and usually disappear within a few days with continued treatment.[13]
Approval
In the European Economic Area, prucalopride was originally approved for the symptomatic treatment of chronic constipation in women in whom laxatives fail to provide adequate relief.[13] Subsequently, it has been approved by the European Commission for use in adults – that is, including male patients – for the same indication.[27]
Contraindications
Prucalopride is contraindicated where there is hypersensitivity to the active substance or to any of the excipients, renal impairment requiring dialysis, intestinal perforation orobstruction due to structural or functional disorder of the gut wall, obstructive ileus, severe inflammatory conditions of the intestinal tract, such as Crohn's disease, and ulcerative colitis and toxic megacolon/megarectum.[13]
CLIP
Prucalopride succinate, a first-in-class dihydrobenzofurancarboxamide, is a selective serotonin (5-HT4) receptor agonist.86–94 The drug, marketed under the brand name Resolor, possesses enterokinetic activity and was developed by the Belgian-based pharmaceutical firm Movetis. Prucalopride alters colonic motility patterns via serotonin 5-HT4 receptor stimulation, triggering the central propulsive force for defecation.95–97 The preparation of prucalopride succinate begins with the commercially available salicylic aniline 124 (Scheme 18). Acidic esterification, acetylation of the aniline nitrogen atom, and ambient-temperature chlorination via sulfuryl chloride (SO2Cl2) converted aminophenol 124 to acetamidoester 125 in 83% yield over the course of three steps.98–102 An unique set of conditions involving sodium tosylchloramide (chloramine T) trihydrate and sodium iodide were then employed to convert 125 to o-phenolic iodide 126, which then underwent sequential Sonogashira/cyclization reaction utilizing TMS-acetylene with tetramethylguanidine (TMG) in the presence of silica gel to furnish the benzofuran progenitor of 127.103 Hydrogenation of this intermediate benzofuranyl Sonagashira product saturated the 2,3-benzofuranyl bond while leaving the chlorine atom intact, ultimately delivering dihydrobenzofuran 127 in excellent yield for the two step sequence. Base-induced saponification and acetamide removal gave rise to acid 128. This acid was activated as the corresponding mixed anhydride and treated with commercial piperidine 129 to construct prucalopride which was stirred at room temperature for 24 h in ethanolic succinic acid to provide prucalopride succinate (XI). The yield for the formation of the salt was not provided.

In vivo | Prucalopride alters colonic contractile motility patterns in a dose-dependent fashion by stimulating high-amplitude clustered contractions in the proximal colon and by inhibiting contractile activity in the distal colon of fasted dogs. Prucalopride also causes a dose-dependent decrease in the time to the first giant migrating contraction (GMC); at higher doses of prucalopride, the first GMC generally occurres within the first half-hour after treatment.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species | Mouse | Rat | Rabbit | Guinea pig | Hamster | Dog |
Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
Rat dose (mg/kg) = mouse dose (22.4 mg/kg) × | mouse Km(3) | = 11.2 mg/kg |
rat Km(6) |
