of 1200 mg twice daily. Maintenance dose 600-800 mg per day in divided
Psychiatry - Elderly:
The same dose ranges may be required in the elderly, but, as a general rule
with the use of psychotropics in elderly patients, starting doses should be
lower and increased gradually, particularly in those with renal impairment.
Psychiatry - Children aged above 6 years old:
3-5 mg/kg body weight/day in devided doses
Sulpiride is primarily excreted renally, and dose adjustments have been
suggested in renal insufficiency.
creatinine clearance 30 to 60 mL/minute – 50% of normal dose
creatinine clearance 10 to 30 mL/minute – 30% of normal dose
creatinine clearance <10 mL/minute – 20% of normal dose.
Phaeochromocytoma and acute porphyria.
Hypersensitivity to sulpiride or to any of the excipients.
Concomitant prolactin-dependent tumours e.g. pituitary gland prolactinomas and
breast cancer (See section 4.8 Undesirable effects).
Association with levodopa or antiparkinsonian drugs (including ropinirole) (See
section 4.5 Interactions with other medicinal products and other forms of interaction).
4.4 Special warnings and precautions for use
Increased motor agitation has been reported at high dosage in a small number of
patients: in aggressive, agitated or excited phases of the disease process, low doses
of sulpiride may aggravate symptoms. Care should be exercised where hypomania is
Extrapyramidal reactions, principally akathisia have been reported in a small number
of cases. If warranted, reduction in dosage or anti-parkinsonian medication may be
As with other neuroleptics, neuroleptic malignant syndrome, a potentially fatal
complication, which is characterised by hyperthermia, muscle rigidity, autonomic
instability, altered consciousness and elevated CPK levels, has been reported. In
such an event, or in the event of hyperthermia of undiagnosed origin, all
antipsychotic drugs, including sulpiride, should be discontinued.
Elderly patients are more susceptible to postural hypotension, sedation and
In patients with aggressive behaviour or agitation with impulsiveness, sulpiride could
be given with a sedative.
Acute withdrawal symptoms, including nausea, vomiting, sweating and insomnia
have been described after abrupt cessation of antipsychotic drugs. Recurrence of
psychotic symptoms may also occur, and the emergence of involuntary movement
disorders (such as akathisia, dystonia and dyskinesia) have been reported.
Therefore, gradual withdrawal is advisable.
Increased Mortality in Elderly people with dementia:
Data from two large observational studies showed that elderly people with dementia
who are treated with antipsychotics are at a small increased risk of death compared
with those who are not treated. There are insufficient data to give a firm estimate of
the precise magnitude of the risk and the cause of the increased risk is not known.
Sulpiride is not licenced for the treatment of dementia-related behavioural
Cases of venous thromboembolism (VTE) have been reported with antipsychotic
drugs. Since patients treated with antipsychotics often present with acquired risk
factors for VTE, all possible risk factors for VTE should be identified before and
during treatment with sulpiride and preventative measures undertaken.
In elderly patients, as with other neuroleptics, sulpiride should be used with particular
caution (see section 4.2).
In children, efficacy and safety of sulpiride have not been thoroughly investigated.
Therefore, caution should be exercised when prescribing to children (see section
When neuroleptic treatment is absolutely necessary in a patient with Parkinson's
disease, sulpiride can be used, although caution is in order.
Neuroleptics may lower the epileptogenic threshold. Cases of convulsions,
sometimes in patients with no previous history, have been reported with sulpiride.
Caution is advised in prescribing it for patients with unstable epilepsy, and patients
with a history of epilepsy should be closely monitored during therapy with sulpiride.
In patients requiring sulpiride who are receiving anti-convulsant therapy, the dose of
the anti-convulsant should not be changed.
Cases of convulsions, sometimes in patients with no previous history, have been
Sulpiride has no significant anticholinergic effect.
As with all drugs for which the kidney is the major elimination pathway, the dose
should be reduced and titrated in small steps in cases of renal insufficiency.
Prolongation of the QT interval:
Sulpiride induces a prolongation of the QT interval (see section 4.8). This effect is
known to potentiate the risk of serious ventricular arrhythmias such as torsade de
Before any administration, and if possible according to the patient's clinical status, it
is recommended to monitor factors which could favour the occurrence of this rhythm
disorder, for example:
- Bradycardia less than 55 bpm
- Electrolyte imbalance in particular hypokalaemia
- Congenital prolongation of the QT interval
- On-going treatment with a medication likely to produce pronounced bradycardia
(< 55 bpm), hypokalaemia, decreased intracardiac conduction, or prolongation of the
QTc interval (see section 4.5)
Sulpiride should be prescribed with caution in patients presenting with these factors
and patients with cardiovascular disorders which may predispose to prolongation of
the QT interval.
Avoid concomitant treatment with other neuroleptics (see section 4.5).
In randomised clinical trials versus placebo performed in a population of elderly
patients with dementia and treated with certain atypical antipsychotic drugs, a 3-fold
increase of the risk of cerebrovascular events has been observed. The mechanism of
such risk increase is not known. An increase in the risk with other antipsychotic drugs
or other populations of patients cannot be excluded. Sulpiride should be used with
caution in patients with stroke risk factors.
Modal Forte tablets contain lactose. Patients with rare hereditary problems of
galactose intolerance, the Lapp lactose deficiency or glucose-galactose
malabsorption should not take this medicine.
Leukopenia, neutropenia and agranulocytosis have been reported with
antipsychotics, including sulpiride. Unexplained infections or fever may be evidence
of blood dyscrasia (see section 4.8) and requires immediate haematological
4.5 Interaction with other medicinal products and other forms of interaction
Levodopa, antiparkinsonian drugs (including ropinirole): reciprocal antagonism of
effects between levopoda or antiparkinsonian drugs (including ropinirole) and
Associations not recommended:
Alcohol: alcohol enhances the sedative effects of neuroleptics.
Avoid the consumption of alcoholic beverages and drugs containing alcohol.
Combination with the following medications which could induce torsades de pointes
or prolong the QT interval (see section 4.4):
− Bradycardia-inducing medications such as beta-blockers, bradycardia-inducing
calcium channel blockers such as diltiazem and verapamil, clonidine; digitalis.
− Medications which induce electrolyte imbalance, in particular those causing
hypokalaemia: hypokalaemic diuretics, stimulant laxatives, IV amphotericin B,
Electrolyte imbalance should be corrected
− Class Ia antiarrhythmic agents such as quinidine, disopyramide.
− Class III antiarrhythmic agents such as amiodarone, sotalol.
− Other medications such as pimozide, haloperidol; methadone, imipramine
antidepressants; lithium, cisapride, thioridazine, IV erythromycin, halofantrine,
Associations to be taken into account:
Antihypertensive agents: antihypertensive effect and possibility of enhanced postural
hypotension (additive effect).
CNS depressants including narcotics, analgesics, sedative H1 antihistamines,
barbiturates, benzodiazepines and other anxiolytics, clonidine and derivatives.
Antacids or sucralfate: The absorption of sulpiride is decreased after co-administration.
Therefore, Modal caplets or Modal Forte Tablets should be administered two hours
before these drugs.
Lithium: lithium increases the risk of extrapyramidal side effects. Discontinuation of
both drugs is recommended at first signs of neurotoxicity.
4.6 Fertility, pregnancy and lactation
A decrease in fertility linked to the pharmacological effects of the drug (prolactin
mediated effect) was observed in treated animals.
Animal studies do not indicate direct or indirect harmful effects with respect to
pregnancy, embryonal/fetal development and/or postnatal development. In humans,
very limited clinical data on exposed pregnancies are available. In almost all cases of
foetal or neonatal disorders reported in the context of sulpiride use during pregnancy,
alternative explanations can be suggested and seem more likely. Therefore the use
of sulpiride is not recommended during pregnancy because of the limited experience.
Neonates exposed to antipsychotics (including sulpiride) during the third trimester of
pregnancy are at risk of adverse reactions including extrapyramidal and/or
withdrawal symptoms that may vary in severity and duration following delivery (see
section 4.8). There have been reports of agitation, hypertonia, hypotonia, tremor,
somnolence, respiratory distress, or feeding disorder. Consequently, newborns
should be monitored carefully.
Sulpiride has been found in the breast milk of treated women. Therefore breast-
feeding is not recommended during treatment.
4.7 Effects on ability to drive and use machines
Even used as recommended, sulpiride may cause sedation so that the ability to drive
vehicles or operate machinery can be impaired. (see section 4.8)
4.8 Undesirable effects
The following CIOMS frequency rating is used, when applicable:
Very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100);

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is
important. It allows continued monitoring of the benefit/risk balance of the medicinal
product. Any suspected adverse events should be reported to the Ministry of Health
according to the National Regulation by using an online form
Experience with sulpiride in overdosage is limited.
The range of single toxic doses is 1 to 16g but no death has occurred even at the
The clinical manifestations of poisoning vary depending upon the size of the dose
taken. After single doses of 1 to 3g restlessness and clouding of consciousness have
been reported and (rarely) extrapyramidal symptoms. Doses of 3 to 7g may produce
a degree of agitation, confusion and extrapyramidal symptoms (see section 4.8
Undesirable Effects); more than 7g can cause, in addition, coma and low blood
The duration of intoxication is generally short, the symptoms disappearing within a
few hours. Comas which have occurred after large doses have lasted up to four
No haematological or hepatic toxicity has been reported.
Sulpiride is partly removed by haemodialysis.
There is no specific antidote to sulpiride. Treatment is only symptomatic. Appropriate
supportive measures should therefore be instituted, close supervision of vital
functions and cardiac monitoring (risk of QT interval prolongation and subsequent
ventricular arrythmias) is recommended until the patient recovers.
If severe extrapyramidal symptoms occur anticholinergics should be administrated.
Overdose may be treated with alkaline osmotic diuresis and, if necessary, anti-
parkinsonian drugs. Coma needs appropriate nursing, and cardiac monitoring is
recommended until the patient recovers. Emetic drugs are unlikely to be effective in
5. Pharmacological properties
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Psycholeptics; Benzamides,
ATC code: N05AL01
Sulpiride is a member of the group of substituted benzamides, which are structurally
distinct from the phenothiazines, butyrophenones and thioxanthenes. Current
evidence suggests that the actions of sulpiride hint at an important distinction
between different types of dopamine receptors or receptor mechanisms in the brain.
Behaviourally and biochemically, sulpiride shares with these classical neuroleptics a
number of properties indicative of cerebral dopamine receptor antagonism. Essential and
intriguing differences include lack of catalepsy at doses active in other behavioural tests,
lack of effect in the dopamine sensitive adenylate cyclase systems, lack of effect upon
noradrenaline or 5HT turnover, negligible anticholinesterase activity, no effect on
muscarinic or GABA receptor binding, and a radical difference in the binding of tritiated
sulpiride to striatal preparations in-vitro, compared to
These findings indicate a major differentiation between sulpiride and classical neuroleptics
which lack such specificity.
One of the characteristics of sulpiride is its bimodal activity, as it has both
antidepressant and neuroleptic properties. Schizophrenia characterised by a lack of
social contact can benefit strikingly. Mood elevation is observed after a few days
treatment, followed by disappearance of the florid schizophrenic symptoms. The
sedation and lack of affect characteristically associated with classical neuroleptics of
the phenothiazine or butyrophenone type are not features of sulpiride therapy.
5.2 Pharmacokinetic properties
Peak sulpiride serum levels are reached 3 - 6 hours after an oral dose. The plasma
half-life in man is approximately 8 hours. Approximately 40% sulpiride is bound to
plasma proteins. 95% of the compound is excreted in the urine and faeces as
5.3 Preclinical safety data
In long-term animal studies with neuroleptic drugs, including sulpiride, an increased
incidence of various endocrine tumours (some of which have occasionally been
malignant) has been seen in some but not all strains of rats and mice studied. The
significance of these findings to man is not known; there is no current evidence of an
association between neuroleptic use and tumour risk in man.
