Neuroleptic malignant syndrome after abrupt discontinuation of neuroleptic and anticholinergic drugs

If you notice any other effects, check with your healthcare professional. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so. By improving muscle control and reducing stiffness, this medicine allows more normal movements of the body as the disease symptoms are reduced. It is also used to control severe reactions to certain medicines that are used to treat nervous, mental, and emotional conditions (e.g., phenothiazine medicine such as prochlorperazine, Compazine®, Mellaril®, Phenergan®, Thorazine®, Trilafon®).

Anecdotally, a slow rate of reduction may reduce the risk of developing a severe protracted syndrome. Anticholinergics are contraindicated in NMS and other cases of hyperthermia or heat-related illness because they block sympathetic innervation of sweat glands, resulting in anhidrosis and potentially complete loss of ability to dissipate a heat load. Consequently, these medications are a major contributing factor to potentially fatal heatstroke in the elderly and in mentally ill patients during increasingly common summer heat waves 81, 82.

  • The panelists agreed that standards for DIMD evaluation and treatment are covered in the 2020 American Psychiatric Association (APA) guidelines for the treatment of adults with schizophrenia (Table 1) 47.
  • For M1/M4 receptor agonists in development for schizophrenia 8, 37, as well as M4 receptor positive allosteric modulators 38, the potentially deleterious effects of centrally acting anticholinergics on antipsychotic efficacy remains to be determined.

The original contributions presented in the study are included in the article/Supplementary Material, further inquiries can be directed to the corresponding author and first author. Discrepancies were resolved by consensus with additional review authors (JH, MM). N.V.A. and S.N.C. were involved in the conception and planning of the expert roundtable discussion. N.V.A., S.N.C., L.C., J.C., R.S.M., J.M.M., A.P., and J.M.S. participated in the expert roundtable featured in this article. All authors contributed to the development of the manuscript and provided critical https://ecosoberhouse.com/ reviews of multiple drafts. Dopaminergic activity is modulated by cholinergic neurons that project from the laterodorsal tegmentum and pedunculopontine tegmentum, two acetylcholine-rich nuclei located in the pons region of the brainstem, along with CINs located within the striatum 11, 15.

Treatments that have been tried empirically in observational studies, with variable success, include benzodiazepines, dopamine agonists, dantrolene, and electroconvulsive therapy 80. Patients with akathisia usually experience overwhelming feelings of alcoholism restlessness and the urge to move, resulting in pacing, walking in place, rocking back and forth, leg swinging, toe tapping, squirming, and fidgeting 4, 9, 30, 56. Due to similarity in symptoms, akathisia may be misdiagnosed as anxiety, potentially resulting in exacerbation of symptoms if the antipsychotic dosage is increased 56.

  • The number of people per treatment group that did not show an improvement in the symptoms of individuals of more than 50% on any TD scale;

  • All cohorts with discontinuation of other medication than antipsychotics were also excluded from the sensitivity analysis.
  • The term ‘withdrawal management’ (WM) has been used rather than ‘detoxification’.
  • If data were continuous we combined data following the formula in the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2011).
  • The blue diamond data marker represents the overall proportion and 95% CI.

More severe reactions or withdrawals may also be more likely when taking strong drugs either for long periods or alongside other types of medications. Dependence appears to occur in a similar way to how it does with other addictive drugs. Dopamine is a type of messenger that is partly responsible for how humans feel pleasure. Withdrawal symptoms may begin after as little as 3–6 weeks of use, even when a person uses the drugs as the doctor directed. Supportive counseling and other targeted therapies or medications may help a person manage the symptoms and improve their quality of life. Research in the British Journal of Clinical Pharmacology notes that an estimated 10–25% of people who use benzos for extended periods experience withdrawal symptoms that last for 12 months or longer.

Anticholinergic drugs (as above) compared to any other intervention to treat TD; or
iii. The rationale for the use of anticholinergic drugs in TD is less clear, as there is a suggestion from animal experiments that the chronic administration of anticholinergics could increase the supersensitivity of dopamine receptors and consequently cause TD (Kane 1994). As a result these drugs have not been widely used for the treatment of antipsychotic‐induced TD. Our study has several limitations, lack of a control group being an obvious one.

Further studies of anticholinergic discontinuation should ideally have a control group, monitor compliance and include measures of quality of life and daily functioning. Trialists find it difficult to benztropine withdrawal identify people with both TD and schizophrenia to participate in trials. Randomised cross‐over design is used in the hope of improving the power of the study to find outcomes of interest.
