Clinical evaluation and serum concentration of zuclopenthixol acetate in psychotic Asian patients: a single-dose preliminary study

Tan CH, Low BL, Ng LL, Khoo YM, Lee HS

Ther Drug Monit, 1993 Apr;15(2):108-12.
PMID: 8099240

Nineteen acutely disturbed psychotic Asian patients were treated with a single intramuscular injection of 50 mg of zuclopenthixol acetate in Viscoleo. Patients were assessed clinically before and after treatment using the Brief Psychiatric Rating Scale (BPRS). Serum zuclopenthixol and the inactive geometric isomer trans(E)-clopenthixol were determined by high-performance liquid chromatography after intramuscular injection. All patients improved, with the BPRS being significantly reduced (p < 0.001) at 72 h after injection. Adverse effects were generally few. The mean +/- SEM serum zuclopenthixol concentrations at 24, 48, and 72 h were 19.9 +/- 2.8, 31.5 +/- 4.5, and 17.8 +/- 2.9 micrograms/L, respectively. trans(E)-Clopenthixol concentrations ranged from negligible to 39.5 micrograms/L. This study confirms that a single intramuscular injection of 50 mg is adequate for managing severely disturbed psychotic patients for the first 3 days. The serum zuclopenthixol concentrations attained in the Asian patients were higher than those reported in Caucasian psychiatric patients. In some patients, a considerable amount of zuclopenthixol had been transformed to trans(E)-clopenthixol.

Quality of life: an assessment of the state of psychosocial rehabilitation of patients with schizophrenia in the community

Hasanah CI, Razali MS

J R Soc Promot Health, 2002 Dec;122(4):251-5.
PMID: 12557735

The subjective quality of life (QOL) of diabetic patients on oral hypoglycaemics was compared to schizophrenic patients who were well controlled with their antipsychotic medications. This comparison was made using the generic quality of life questionnaire produced by the World Health Organization QOL (WHOQOL) group, namely the WHOQOL-100. Statistical analysis showed that there was no significant difference in the psychological well-being and level of independence between the two groups. However, such measures revealed that the most impaired aspect of well-being in the schizophrenic group was the social relationship. Subjective QOL assessment is able to reveal deficits or handicaps that are obscure and probably difficult to appreciate on objective social and clinical evaluation. Such findings are valuable in planning the rehabilitative need of schizophrenic patients in the community.

Remitted male schizophrenia patients with sexual dysfunction

Kheng Yee O, Muhd Ramli ER, Che Ismail H

J Sex Med, 2014 Apr;11(4):956-965.
PMID: 23845160 DOI: 10.1111/jsm.12246

INTRODUCTION: Despite the high prevalence of sexual dysfunction among male schizophrenia patients, there is still a paucity of research on this area.
AIMS: The study aims to determine the prevalence of sexual dysfunction and any association between male patients with schizophrenia in remission and the sociodemographic profile, medication, depression, anxiety, psychopathology of illness, body mass index, and waist circumference.
METHODS: A cross-sectional study with nonprobability sampling method was conducted in a psychiatric outpatient clinic in Taiping Hospital (Perak, Malaysia) over a 7-month period. A total of 111 remitted male schizophrenia patients were recruited. The validated Malay version of the International Index of Erectile Function (Mal-IIEF-15) was administered to the patients and assessed over 4-week duration in the domains of erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. Logistic regression analysis was employed.
MAIN OUTCOME MEASURES: Prevalence and associated factors for sexual dysfunction in each domain are the main outcome measures.
RESULTS: All five domains of sexual functioning in patients showed a high prevalence of dysfunction ranging from 78.4% to 97.1% with orgasmic dysfunction being the least impaired and intercourse satisfaction the worst impaired. Among the domains, only orgasmic dysfunction was significantly associated with race, i.e., Chinese at lower risk for impairment than the Malays (OR = 0.23; 95% CI: 0.07, 0.76; P = 0.018); education, i.e., patients with education higher than primary level were at higher risk for dysfunction (OR = 6.49; 95% CI: 1.32, 32.05; P = 0.022); and Positive and Negative Syndrome Scale (PANSS)-positive subscale, i.e., higher PANSS-positive score was a protective factor for orgasmic dysfunction (OR = 0.54; 95% CI: 0.33, 0.89; P = 0.015).
CONCLUSIONS: The prevalence of sexual dysfunction was generally high. Malay patients and those with education higher than primary level were at higher risk for orgasmic dysfunction whereas higher PANSS-positive score was protective against the impairment. The high rate of sexual dysfunction in schizophrenia patients warrants a routine inquiry into patients' sexuality and the appropriate problems being addressed.

Adjunctive mood stabilizer treatment for hospitalized schizophrenia patients: Asia psychotropic prescription study (2001-2008)

Sim K, Yong KH, Chan YH, Tor PC, Xiang YT, Wang CY, et al.

Int. J. Neuropsychopharmacol., 2011 Oct;14(9):1157-64.
PMID: 21557883 DOI: 10.1017/S1461145711000563

Recent studies indicate relatively high international rates of adjunctive psychotropic medication, including mood stabilizers, for patients with schizophrenia. Since such treatments are little studied in Asia, we examined the frequency of mood-stabilizer use and its clinical correlates among hospitalized Asian patients diagnosed with schizophrenia in 2001-2008. We evaluated usage rates of mood stabilizers with antipsychotic drugs, and associated factors, for in-patients diagnosed with DSM-IV schizophrenia in 2001, 2004 and 2008 in nine Asian regions: China, Hong Kong, India, Korea, Japan, Malaysia, Taiwan, Thailand, and Singapore. Overall, mood stabilizers were given to 20.4% (n=1377/6761) of hospitalized schizophrenia patients, with increased usage over time. Mood-stabilizer use was significantly and independently associated in multivariate logistic modeling with: aggressive behaviour, disorganized speech, year sampled (2008 vs. earlier), multiple hospitalizations, less negative symptoms, younger age, with regional variation (Japan, Hong Kong, Singapore>Taiwan or China). Co-prescription of adjunctive mood stabilizers with antipsychotics for hospitalized Asian schizophrenia patients increased over the past decade, and was associated with specific clinical characteristics. This practice parallels findings in other countries and illustrates ongoing tension between evidence-based practice vs. individualized, empirical treatment of psychotic disorders.

Fulltext The association between dyslipidaemia and types of antipsychotic medications among patients with chronic schizophrenia

Ruzanna ZZ, Ong LY, Cheah YC, Fairuz A, Midin M

Med J Malaysia, 2012 Feb;67(1):39-44.
PMID: 22582547 MyJurnal

This cross sectional study aimed to explore the association between dyslipidaemia and types of antipsychotics in 100 patients with chronic schizophrenia. Lipid profile, weight, height and waist circumference together with other relevant factors were measured. We found there was a high rate of dyslipidaemia among patients with chronic schizophrenia treated with antipsychotics (66%), however there was no significant difference found between typical or atypical antipsychotics (OR=1). All sociodemographic and clinical factors were not significantly associated with dyslipidaemia. Only non-Malays were found to have significant dyslipidaemia (p<0.1). Effective management is needed to deal with the dyslipidaemia in this group.

Fulltext The use of aripiprazole in early onset schizophrenia: safety and efficacy

Normala I, Hamidin A

Med J Malaysia, 2009 Sep;64(3):240-1.
PMID: 20527278 MyJurnal

The use of atypical antipsychotic agents in early onset schizophrenia is rising despite its limited data on efficacy, safety and tolerability. Early onset schizophrenia warrants effective pharmacological treatment that is safe and well tolerated by children and adolescent population. Existing atypical agents are not completely free of side effects. Aripiprazole has unique properties that differ from other atypical antipsychotics and fill up the missing gaps, as it is associated with minimal metabolic complications and extrapyramidal side effects that are more commonly seen in other atypical agents. It offers a better option for this population and may possibly be considered as first line treatment in future. This case report demonstrates the efficacy and safety of Aripiprazole in children and adolescent population.

Fulltext Involvement of cytochromes p450 in drug-drug interactions: an overview

Ong CE, Teh LK, Ismail R

Med J Malaysia, 2002 Jun;57(2):251-60.
PMID: 24326665

Drug interactions can cause iatrogenic disease. If concurrent medications are taken, the potential exists for a drug interaction to occur. Renewed interest in the topic interactions has been generated by the fatal interactions involving non-sedating histamine H-1 antagonists and the recent intriduction of two therapeutic agents, the selective serotonin reuptake inhibitors (SSRIs) and HIV protease inhibitors, for the treatment of depression and AIDS, respectively. These three therapeutic agents have been implicated in clinically significant drug interactions. The consequences of these interactions vary in clinical significance, extent, and effect. Some interactions are theoretical whereas others may lead to severe iatrogenic adverse experiences including lethal consequences.The purpose of this review is to alert the medical practioner to potential drug interactions that may occur when these drugs are prescribed to patients. The pharmacological basis and clinical signficance of these interactions are reviewed. The pharmacological mechanisms underlying these interactions are illustrative of those that may be involved for many other medications. Doctors should be aware of the potential pitfall that may occur when certain groups of drugs are prescribed with concurrent medications.

Fulltext A 3 year case study of alcohol related psychotic disorders at Hospital Seremban

George S, Chin CN

Med J Malaysia, 1998 Sep;53(3):223-6.
PMID: 10968157

This paper reports the characteristics and psychopathology of alcohol dependents with alcohol induced psychotic disorder admitted to the Seremban Hospital. The method is that of a case study of all alcohol dependents with alcohol induced psychotic disorder admitted to the Psychiatric Ward, Hospital Seremban over 3 years (1993-1995). There were 34 subjects, 30 Indians, 3 Chinese and 1 Malay with a mean age of 43 years. 32 were men and predominantly of Social Class IV and V (91%). They had a mean duration of drinking of 14.2 years and had a mean weekly consumption of 69.5 units of alcohol. There was a family history of alcohol dependence in (44%). The majority (68%) consumed samsu with beer the second choice. Auditory hallucinations (26) and delusions (16) were common while visual hallucinations (3) and depression (2) were less frequent. Speech disorder occurred in 4 subjects. 2 developed delirium tremens and 1 died. Liver function test was normal in 55%. All except the death from delirium tremens responded to treatment with a combination of anxiolytics, thiamine and antipsychotics and were rapidly discharged. The mean stay was 7 days. However, (68%) did not return for follow up and only 4 were abstinent from alcohol at the time of follow up.

Fulltext Comparison of risperidone and other neuroleptics in the management of chronic schizophrenia using cognitive therapy

Azhar MZ

Med J Malaysia, 2000 Mar;55(1):7-13.
PMID: 11072484

A number of psychological approaches to alleviating psychotic symptoms have been reported in the literature. The latest technique among them is cognitive therapy (CT). This paper describes an open trial that makes use of cognitive psychotherapy to treat chronic drug resistant delusions (more than 2 years duration) in 20 patients with schizophrenia. The positive response of all patients with the absence of symptom replacement and maintenance of response at 3 months follow-up, seem to imply that this technique is useful and more effort needs to be invested into this new area of psychotherapy for psychosis. This paper also shows that those patients on risperidone maintenance respond better to CT than those on other neuroleptics.

Fulltext A double blind comparison of zuclopenthixol acetate with haloperidol in the management of acutely disturbed schizophrenics

Chin CN, Hamid AR, Philip G, Ramlee T, Mahmud M, Zulkifli G, et al.

Med J Malaysia, 1998 Dec;53(4):365-71.
PMID: 10971979

The aim of this study was to evaluate the efficacy and side effects of zuclopenthixol acetate compared with haloperidol in the management of the acutely disturbed schizophrenic patient. Suitable subjects diagnosed as having schizophreniform disorder or acute exacerbation of schizophrenia admitted to the psychiatric wards Hospital Kuala Lumpur were randomised to receive either zuclopenthixol acetate or haloperidol. They were rated blind for three consecutive days using the Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression (CGI) and UKU Side Effects Scale. Apart from repeat injections of the same medication, no other anti-psychotic was given for the duration of the study. 50 subjects entered the study of which 44 completed. 23 were given zuclopenthixol acetate and 21 haloperidol. Both groups significantly reduced BPRS and CGI scores on all 3 days compared to the initial rating (p < 0.001). There was however no difference between the zuclopenthixol acetate and haloperidol group scores on all days (p > 0.05). More subjects on haloperidol than zuclopenthixol required more than 1 injection during the study. Both groups had minimal side effects. Zuclopenthixol acetate was effective in the management of the acutely disturbed schizophrenic.

Fulltext Neuroleptic malignant syndrome in Malaysia: a university hospital experience

Lee MK, Ong SB, Tan CT, Loh TG

Med J Malaysia, 1992 Sep;47(3):200-7.
PMID: 1362794

The neuroleptic malignant syndrome (NMS) is a potentially fatal complication of antipsychotic therapy. A retrospective study of nine patients seen over six years at the University Hospital, Kuala Lumpur (UHKL), is described. The estimated annualised incidence was 1.2 per 1000 in-patients with psychosis. No ethnic difference was detected. Clinical features were similar to experiences elsewhere, with wide variability seen in the severity of illness. The neuroleptic drugs implicated were haloperidol, trifluoperazine, chlorpromazine, fluphenazine and clopenthixol. Treatment consisted of withdrawal of offending drugs and supportive measures. Specific therapy was given to five patients. There was one death. At follow-up no deterioration was detected. A different neuroleptic drug was successfully re-introduced in four patients. In view of the wide usage of major tranquillizers, a high degree of clinical awareness of this serious complication is necessary for early diagnosis to reduce morbidity and mortality.

Fulltext All elevated creatine kinase is not neuroleptic malignant syndrome

Maniam T, Rahman MA

Med J Malaysia, 1994 Sep;49(3):252-4.
PMID: 7845275

Creatine kinase (CK) is an enzyme that is found widely in muscle tissues. Raised levels would occur when there is muscle damage. Raised levels are used as one of the diagnostic criteria for Neuroleptic Malignant Syndrome (NMS). This study looks at CK levels in 30 psychotic inpatients without NMS and compares them with 10 patients with NMS. It was found that 67% of the patients without NMS had raised CK levels, 20% of whom had levels in excess of 1000 IU/L. The rest had a two to five-fold increase over normal limits. Raised levels were associated with the use of intramuscular injections and physical restraints, situations which are well known to result in muscle injury. All the NMS patients had raised CK levels but 40% had levels below 1000 IU/L. Our findings support the idea that CK levels, though helpful, should be interpreted with care as raised levels are nonspecific.

A Bibliometric Analysis of Scientific Production on Second-Generation Anti-Psychotic Drugs in Malaysia

López-Muñoz F, Povedano-Montero FJ, Chee KY, Shen WW, Fernández-Martín P, García-Pacios J, et al.

Malays J Med Sci, 2018 May;25(3):40-55.
PMID: 30899186 DOI: 10.21315/mjms2018.25.3.5

Objective: We carried out a bibliometric study on the scientific papers related to second-generation antipsychotic drugs (SGAs) in Malaysia.
Methods: With the SCOPUS database, we selected those documents made in Malaysia whose title included descriptors related to SGAs. We applied bibliometric indicators of production and dispersion, as Price's law and Bradford's law, respectively. We also calculated the participation index of the different countries. The bibliometric data were also been correlated with some social and health data from Malaysia (total per capita expenditure on health and gross domestic expenditure on R&D).
Results: We found 105 original documents published between 2004 and 2016. Our results fulfilled Price's law, with scientific production on SGAs showing exponential growth (r = 0.401, vs. r = 0.260 after linear adjustment). The drugs most studied are olanzapine (9 documents), clozapine (7), and risperidone (7). Division into Bradford zones yields a nucleus occupied by the Medical Journal of Malaysia, Singapore Medical Journal, Australian and New Zealand Journal of Psychiatry, and Pharmacogenomics. Totally, 63 different journals were used, but only one in the top four journals had an impact factor being greater than 3.
Conclusion: The publications on SGAs in Malaysia have undergone exponential growth, without evidence a saturation point.

Oculogyric spasm in Asian psychiatric in-patients on maintenance medication

Tan CH, Chiang PC, Ng LL, Chee KT

Br J Psychiatry, 1994 Sep;165(3):381-3.
PMID: 7994510

BACKGROUND: The objective was to investigate the occurrence and characteristics of oculogyric spasm (OGS) in an Asian country.
METHOD: All 2035 Asian (88% Chinese, 7% Malays and 5% Indonesians) psychiatric in-patients in the state psychiatric hospital in Singapore were surveyed for occurrence of oculogyric spasm (OGS) over a two-month period.
RESULTS: Thirty-four patients (1.7%) developed OGS (53% male and 47% female). All the 34 patients had been on maintenance antipsychotic drugs for more than five months. Eighteen patients had recurrent attacks. The mean chlorpromazine equivalent daily dose for those patients with recurrent OGS was 511 mg. This was significantly higher (P < 0.05) than the 277 mg daily dose received by those without recurrent OGS. Most (68%) of the attacks occurred between 1400-2000 h suggesting that OGS may have a diurnal variation.
CONCLUSIONS: OGS presenting as tardive dystonia may be due to a relative increase in cholinergic activity.
