What is Neuromalignant syndrome?

What is Neuromalignant syndrome?

Neuroleptic malignant syndrome (NMS) is a rare, but life-threatening, idiosyncratic reaction to neuroleptic medications that is characterized by fever, muscular rigidity, altered mental status, and autonomic dysfunction. NMS often occurs shortly after the initiation of neuroleptic treatment, or after dose increases.

Which drug causes neuroleptic malignant syndrome?

The primary trigger of NMS is dopamine receptor blockade and the standard causative agent is an antipsychotic. Potent typical neuroleptics such as haloperidol, fluphenazine, chlorpromazine, trifluoperazine, and prochlorperazine have been most frequently associated with NMS and thought to confer the greatest risk.

What is the difference between neuroleptic malignant syndrome and serotonin syndrome?

NMS and serotonin syndrome are rare, but potentially life-threatening, medicine-induced disorders. Features of these syndromes may overlap making diagnosis difficult. However, NMS is characterised by ‘lead-pipe’ rigidity, whilst serotonin syndrome is characterised by hyperreflexia and clonus.

Is NMS reversible?

The mortality rate of NMS is estimated to be as high as 20% and the usual cause of death is due to acute renal failure. Fortunately, with early recognition and intervention, it is usually reversible without any serious complications.

Which signs and symptoms may occur in neuroleptic malignant syndrome?

The condition is most commonly associated with antipsychotic drugs, although other drugs can also cause it to occur. The most common symptoms of NMS include very high fever, rigid muscles, and changes in mental state. Other symptoms like excessive sweating, rapid heartbeat, and tremors may also be present.

Why do antipsychotics cause orthostatic hypotension?

Orthostatic hypotension is a common side effect of atypical antipsychotics. It is caused by anticholinergic or alpha-1 adrenoceptor blockage [14]. Alpha-1adrenoceptors cause vasoconstriction in certain vascular beds. The blockade of these receptors leads to vasodilation which causes blood pressure to decline.

How do you test for neuroleptic malignant syndrome?

However, the following laboratory studies may be indicated, to assess severity and complications or rule out other diagnostic possibilities:

1. Complete blood count (CBC)
2. Blood cultures.
3. Liver function tests (LFTs)
4. Blood urea nitrogen (BUN) and creatinine levels.
5. Calcium and phosphate levels.
6. Creatine kinase (CK) level.

Which antipsychotic has the highest incidence of EPS?

risperidone

Are EPS symptoms reversible?

In most cases, symptoms are reversible in days or weeks, but occasionally, especially in the elderly, or if long-acting injectable antipsychotics are used, symptoms may last for months. In about 15% of cases, parkinsonism may persist, raising the possibility of underlying Parkinson’s disease.

What is the safest antipsychotic medication?

Clozapine and olanzapine have the safest therapeutic effect, while the side effect of neutropenia must be controlled by 3 weekly blood controls. If schizophrenia has remitted and if patients show a good compliance, the adverse effects can be controlled.

Which antipsychotic has less side effects?

Aripiprazole is similar in effectiveness to risperidone and somewhat better than ziprasidone. Aripiprazole had less side- effects than olanzapine and risperidone (such as weight gain, sleepiness, heart problems, shaking and increased cholesterol levels).

Are there any antipsychotics that don’t cause weight gain?

Haloperidol, lurasidone, ziprasidone, aripiprazole and amisulpiride carry lesser risk of weight gain, compared to other antipsychotics.

How much weight do you gain on antipsychotics?

Prospective studies revealed that the average weight gain during the first year of treatment was 11.7 to 13.9 lb for clozapine, 15 to 26 lb for olanzapine, 4.4 to 5.1 lb for risperidone, 6.1 to 13.3 lb for quetiapine, and less than 2 lb for aripiprazole and ziprasidone.

How do you avoid weight gain on antipsychotics?

Wherever possible use drugs with a lower risk of weight gain. Monitor weight and Body Mass Index (BMI) during antipsychotic treatment. More regular measurements are needed in the first few months of treatment as this is when the risk of weight gain is highest. Use lifestyle approaches to manage weight gain.

Will I lose weight if I stop taking antipsychotics?

Weight loss may occur once a person stops taking their medication. However, this will depend on the drug in question and the individual. People who stop taking antipsychotics usually see gradual weight loss.

Will I lose weight if I stop taking antihistamines?

However, one of the side effects associated with some antihistamines is weight gain, and some patients have even suggested they’ve experienced weight loss after stopping antihistamines.

Is it possible to lose weight on epilim?

It is certainly true that Epilim is well recognised as being a drug which can cause both an increase in appetite and weight. It is also true that once Epilim is reduced or stopped, any weight gain can gradually disappear, although it is important that diet and exercise are used as well.

Will I lose weight after stopping antidepressants?

If you decrease your daily calorie intake as a result, you could potentially lose weight by stopping your antidepressants. On the other hand, if you experience loss of appetite with depression, and your depression comes back after stopping antidepressants, you may also lose weight.

Does depression come back after stopping antidepressants?

Don’t stop taking your antidepressant when you start feeling better. Quitting too soon could lead to a return of your depression. Your doctor will help you determine when, and if, quitting your antidepressant is advisable.

Do I need to take antidepressants for the rest of my life?

Although it may be tempting to stop medication as your mood lifts, continue taking it for as long as your doctor recommends. Most doctors advise patients to take antidepressants for six months to a year after they no longer feel depressed. Stopping before that time can cause depression to return.
