The reference site for Sulpiride

Sulpiride is an atypical antipsychotic drug  of the benzamide class used mainly in the treatment of psychosis associated with schizophrenia and major depressive disorder.

WHAT IS Sulpiride?

Sulpiride is a selective dopamine D2 antagonist drug used mainly in the treatment of psychosis (e.g. schizophrenia) and depression. It is sometimes referred to as a ‘major tranquilliser’, and works by blocking dopamine receptors in the brain.

This medication has strong chemical and clinical similarities to the novel anti-psychotic amisulpride, and is a substituted benzamide.

Sulpiride is more commonly used in Europe and Japan, and has currently not been approved for use in the US and Canada. Nevertheless, this medication is sold under numerous brand names including Bosnyl®, Dogmatil®Dolmatil®, Eglonyl®, Meresa®Sulpor®, and Sulpitil®.

Why is this medication prescribed?

Sulpiride is a selective dopamine D2 antagonist (and also a substituted benzamide neuroleptic), which is used as an antipsychotic and also as an antidepressant/anxiolytic in some countries.

Like all antipsychotic drugs, sulpiride is thought to work by blocking dopamine receptors in the brain, and works by exerting antipsychotic action, antiemetic actions and an effect on gastrin secretion.

Additionally, sulpiride is effective in the treatment of acute and chronic schizophrenia but does not appear to offer a significant advantage over other antipsychotic agents.

Mechanism of action:

Sulpiride acts by blocking a variety of receptors in the brain, particularly dopamine receptors. Dopamine is involved in transmitting signals between brain cells. When there is an excess amount of dopamine in the brain it causes over-stimulation of dopamine receptors. These receptors normally act to modify behaviour and over-stimulation may result in psychotic illness. Sulpiride blocks these receptors and stops them becoming over-stimulated, thereby helping to control psychotic illness’s such as schizophrenia.

Other uses for this medicine

Other possible therapeutic uses of sulpiride that are currently under investigation include:

Contraception:
A combination of sulpiride and norethindrone was reported more effective than norethindrone alone in suppressing urinary excretion of estrone and pregnanediol in one small study. It was suggested that the combination may improve contraception by virtue of mimicking lactation secondary to sulpiride-induced increases in prolactin secretion. The use of sulpiride in this manner has been criticized due to its potential to produce tardive dyskinesia and because combination oral contraceptives are highly effective. Other investigators suggest that increasing the dose of progestogen alone would achieve the same effect as combined sulpiride therapy.

Duodenal Ulcer:
Oral sulpiride 50 to 100 mg 3 times daily was reported to enhance the efficacy of antacids (aluminum-magnesium hydroxide) on duodenal ulcer healing in a controlled study. In another study, duodenal ulcer recurrence rates were healed with a combination of sulpiride (200 mg daily) plus cimetidine (800 mg daily) as compared with cimetidine alone. Further studies are required to assess the potential role of sulpiride in Peptic Ulcer disease, including comparisons with bismuth subsalicylate or colloidal bismuth subcitrate regimens.

Huntington’s Disease:

Oral sulpiride has reduced abnormal movements in patients with Huntington’s disease. However, no functional improvement was observed.

Inadequate Lactation:
Oral sulpiride 50 mg two or three times daily for 4 days to 4 weeks has increased serum prolactin levels and enhanced breast milk yield in puerperal women with inadequate lactation. In one study, efficacy was observed in primiparous but not multiparous mothers; this was attributed to spontaneous increases in milk secretion in the multiparous group without medication. Further investigations are needed before sulpiride can be recommended for improving lactation, including potential neonatal endocrinogical effects. Some investigators suggest that simply increasing the frequency of nursing is the best stimulus to inadequate lactation.

Neuroses:
Sulpiride 150 to 300 mg daily has been reported effective in the treatment of neurotic disorders, with symptoms of anxiety, mixed anxiety-depression, tension, obsessions, and hypochondriasis, in limited double-blind studies. In these studies, however, sulpiride offered no apparent advantage over chlordiazepoxide or diazepam. Diazepam was superior to sulpiride with regard to alleviation of psychic anxiety in one trial.

Tardive Dyskinesia:

Due to a potential lower tendency to induce extrapyramidal disorders by virtue of selective dopamine D2 receptor antagonism, oral sulpiride has been used as an alternative to phenothiazines and butyrophenones to suppress tardive dyskinesia symptoms. In limited studies, sulpiride 200 to 1200 mg daily has been effective in reducing movement abnormalities in patients which tardive dyskinesia. However, parkinsonian symptoms (which were intended to be avoided) occurred in 30% to 75% of these patients; an increase in tardive dyskinesia symptoms was also observed occasionally with institution of sulpiride therapy. Recently, several reports of tardive dyskinesia and tardive dystonia attributed to sulpiride therapy of anxiety, depression, and gastrointestinal symptoms have been described. Until further is known regarding the propensity of the drug to induce tardive dyskinesia, its use for the treatment of this disorder is not recommended.

Tourette’s Disorder:

Oral sulpiride 200 to 1000 mg daily was reported beneficial in the treatment of Gilles de la Tourette syndrome in a retrospective study. Reductions in the frequency or severity of vocal or motor tics, obsessional behavior, and aggression were observed. A controlled study comparing sulpiride with haloperidol is needed to determine if sulpiride will have a role in this disorder.

Sulpiride can cause drowsiness, dizziness and blurred vision. Make sure you know how you react to sulpiride before driving, operating machinery or doing any other jobs which could be dangerous if you were not fully alert or able to see properly.

Alcohol will increase feelings of drowsiness. If you do drink alcohol, drink only in moderation and be aware of its effects on you.

Before having any surgery, including dental or emergency treatment, tell the surgeon, doctor or dentist that you are taking Sulpiride.

Additionally, sulpiride can occasionally cause a dry mouth. If you experience this, try chewing sugar-free gum, sucking sugar-free sweets or pieces of ice. If a dry mouth becomes too troublesome discuss the problem with your doctor or pharmacist.

Sulpiride can cause some people’s skin to become more sensitive to sunlight than it usually is. Try to avoid the sun and sunbeds until you know how your skin reacts or use a suncream higher than factor 15.

What should I do if I forget a dose?

If you miss a dose, take it as soon as you remember. However, if it is nearly time for your next dose, just take that one as normal and tell your doctor that you missed one.

Never attempt to make up for your missed dose by taking extra medication or doubling up as this can cause serious side effects.
