The exclusion criteria included contraindications for the use of olanzapine e.g. hypersensitivity to olanzapine ; , age below 18 or over 65 years, and absence of agitation symptoms. Patients refusing to take oral drugs and those with serious somatic diseases which could affect the course of observation were excluded as well. The necessity to discontinue olanzapine or initiation of another antipsychotic was equivalent with patient exclusion. No additional tests other than those routinely performed in everyday clinical practice were planned in the study protocol. The protocol included 9 observations to be conducted at time 0 baseline observation ; , after 1, 2, 6, and 72 hours of treatment, and after 7 days of treatment final observation ; . Assessment methods CGI-S scale Clinical Global Impression Severity ; . Severity of illness was assessed during all the observations. The scores range from 1 healthy ; to 7 extreme severity of symptoms ; . CGI-I scale Clinical Global Impression Improvement ; . The assessments were done during all observations, beginning from the second after 1 h of treatment ; . Scores from 1 markedly improved ; to 7 markedly worse ; , with 4 being the patient's condition unchanged compared with observation 1 baseline ; . PANSS-EC scale Positive and Negative Syndrome Scale Excitement Component ; used for the assessment of agitation during all the observations evaluates the severity of 5 agitation symptoms: excitement, hostility, tension, uncooperativeness, and poor impulse control. Scores for individual symptoms range from 1 absence of the symptom ; to 7 extreme severity of the symptom ; . PANSS scale Positive and Negative Syndrome Scale for Schizophrenia ; and its subscales: PANSS-P positive symptoms ; , PANSS-N negative symptoms ; , and PANSS-G general psychopathology ; . The scale was applied during observations 1, 6, 8 and 9, i.e. at the beginning of the study before the treatment was started ; , after 24 h, 72 h and 7 days final observation ; . The incidence of adverse events was also recorded. Statistical analysis For statistical analysis, the two-sided t-test was used. All inferences were based on comparison with a two-sided level of significance of p 0.05 and oxcarbazepine.

Adverse Event. It is hard to know if most of the diseases listed in Table 1 were accurately diagnosed, in view of the level of sophistication of clinical medicine at the time and adverse conditions at the so-called hospital.13 The underlying nutritional deficiencies of protein, calories, vitamins, minerals and other essential factors had broad effects in compromising these individuals. These included deficient immune responses, poor wound healing, and inadequate organ system function such as night blindness. The term anasarca was often used interchangeably with dropsy in the Civil War era and could indicate generalized edema from many causes including protein deficiency, beri-beri heart failure, or just cardiac or renal disease. Similarly, ascites could be a manifestation of liver failure, protein deficiency, heart disease, or in some cases scurvy. The list of complicating respiratory infections including catarrh, laryngitis, pleuritis, and pneumonia would be expected in these men with mild-to-severe immunodeficiency and exposure and oxytetracycline. Due to the large scope of toxicology nowadays, one finds more than one definition on toxicology in the literature. While a clinician would focus on the clinical safety of drugs, an environmental toxicologist emphasizes the toxicity of compounds on flora and fauna, whereas a regulatory toxicologist aims at estimation of risk and of the contribution to the risk benefit ratio for its intended use. A term that has become very important for toxicologist independent of the individual field is the so-called "risk assessment". Risk assessment or safety assessment, respectively, consists of four components: I ; identify hazard, II ; characterize hazard, III ; describe exposure, and IV ; present risk. In this context it is important to point out, that hazard describes the potential for a damaging effect whereas the risk includes the likelihood that a hazard would occur. In case of drug development these data are contributing to the go or no-go decision in drug development. However, in the interpretation of safety data, risk-benefit considerations need to be applied. The therapeutic benefit has to be analyzed in view of the indication. The degree of adverse drug reaction, which is acceptable, is different for an anti-cancer therapy compared to treatment of hypertension, for example, olanzapine treatment.

Ms. J. was a 38-year-old woman with no prior or family history of thrombocytopenia, bleeding disorder, autoimmune disease, radiation therapy, or any other significant medical illness. She had a history of three psychiatric hospitalizations for schizoaffective disorder. During the first two hospitalizations she was treated with haloperidol and amitriptyline. Her platelet count while she was on these medications was 230 109 L. She had never received benztropine. During her last hospitalization she was started on olanzzapine 10 mg po qd ; and amitriptyline 150 mg po hs ; . At that time her platelet count was 224 109 L. Her psychotic symptoms improved and she was discharged. Ms. J. was hospitalized 1 month later due to bruises caused by severe thrombocytopenia. Her blood white cell count was 11.44 109 L, hemoglobin 120 g L, hematocrit 36.9%, and platelet count 20 109 L. The blood chemistry panel was within normal limits. Serum iron and antinuclear antibody studies were within normal limits. The physical examination on admission was unremarkable, except for bruises. Ms. J.'s psychiatric medications were discontinued because of the possibility of drug-induced thrombocytopenia. Psychiatric consultation was requested regarding the management of her mental illness in the setting of introducing prednisone therapy. At the time of psychiatric consultation, Ms. J. did not show any Psychosomatics 41: 3, May-June 2000. Examples systemic hypertension; coronary artery disease; diabetes mellitus; history of cardiotoxic drug therapy or alcohol abuse; personal history of rheumatic fever; family history of cardiomyopathy and pravastatin.
Complained of muscle cramps in her neck, shoulders, and thighs. The medical student who examined her recommended a creatinine phosphokinase test be done. The result was 1572 U L. The symptoms subsided, and her creatinine phosphokinase levels returned to normal 2 weeks after olanzapkne was discontinued--admittedly anecdotal evidence but impressive, nevertheless. --Ralph Scandiffio, MD, CCFP Gloucester, Ont by e-mail Reference.

Gardner et al. with water and 5% methanol, and the olanzapine was eluted with methanol. The drug was shown to be 99% pure by HPLC. Analytical studies. HPLC was performed using a Shimadzu system LC-600 pump; SPD-6A UV spectrophotometer set at 254 nm, and a C-R6A integrator; Shimadzu, Kyoto, Japan ; . An Ultracarb ODS 30 column 2 100 mm, 5 m; Phenomenex, Torrance, CA ; equipped with a 2 30 guard column was used for the chromatography. The mobile phase consisted of water acetonitrile acetic acid 79: 20: 1, v v v ; containing 2 mM ammonium acetate unless stated otherwise and was degassed before use. LC MS and LC MS MS were carried out on a Sciex API III mass spectrometer Perkin-Elmer, Sciex, Thornhill, Ontario, Canada ; equipped with an Ion Spray interface. Analyses were performed using an ionizing voltage of 5 kV, and the orifice voltage was 60 V. Collision-induced dissociation of selected precursor ions was performed in the RF-only quadrupole region, and argon was used as target gas at an energy of 26 eV. The mobile phase flow rate was 0.2 ml min, and a postcolumn splitter decreased the flow through the mass spectrometer to 20 l min. 1H NMR spectra dimethylsulfoxide-D6 ; were recorded at 500 MHz with a Varian Unity Plus 500 Spectrometer Varian Associates, Palo Alto, Ca. ; . Oxidation of olanzapine by hypochlorous acid. A Hewlett Packard diode-array spectrophotometer HP 8452A; Hewlett Packard, Palo Alto, CA ; was used to determine the rate of oxidation of olanzapine by hypochlorite. Scanning of the reaction mixture was initiated immediately after the addition of NaOCl 40 l, 5 mM aqueous solution ; to a solution of the drug [2 ml, 100 M in phosphate buffer 0.1 M, pH 6.0 ; ] with rapid stirring. A Hi-Tech stopped-flow spectrophotometer Stopped-Flow SHU; Hi-Tech Scientific., Salisbury, UK; dead time, 2 msec ; was used to obtain accurate kinetic data on the oxidation of olanzapine and clozapine by HOCl. Concentrations of drug and NaOCl were 500 and 50 M, respectively. Reactions were performed in PBS 137 mM sodium chloride, 8 mM disodium hydrogen phosphate, 1.5 mM potassium dihydrogen phosphate, and 2.7 mM potassium chloride, pH 6.0 ; or in phosphate buffer 0.1 M, pH 6.0 ; , and the reactive intermediates were monitored at 540 nm olanzapine ; or 460 nm clozapine ; . Mass spectra of the reactive intermediate of olanzapine were obtained using a flow system coupled to the mass spectrometer. An olanzapine solution 250 M in water adjusted to pH 6.0 with acetic acid ; and a solution of NaOCl 62.5 M aqueous solution ; were fed into an Mixing Tee dead volume, 3.1 l ; Upchurch Scientific, Concord, Ontario, Canada ; . The flow rate was 50 l min for olanzapine and 100 l min for hypochlorite. From the mixing chamber, the products flowed through a fused silica capillary to the mass spectrometer in 10 sec with a splitter just before the mass spectrometer inlet decreasing the flow rate to 15 l min. Trapping of the olanzapine reactive intermediate with glutathione and NAC. NaOCl 250 l, 1 M aqueous solution ; was added to olanzapine 5 ml, 20 mM in an aqueous solution of 60% ethanol with the pH adjusted with 20 l of acetic acid ; with rapid stirring. The solution immediately became dark red, and GSH or NAC 2 ml, 0.2 M aqueous solution ; was quickly added to the solution. The reaction products were analyzed by LC MS. The mobile phase consisted of water acetonitrile acetic acid 79: 20: 1, v v v ; containing 2 mM ammonium acetate. Purification of NAC adducts of the olanzapine reactive intermediate. After reaction of the olanzapine reactive intermediate with NAC as described above ; , the sample was concentrated under reduced pressure. The pH was adjusted to 9.0 with NaHCO3, and the solution was extracted with ethyl acetate three times 15 ml ; . The aqueous layer was adjusted to pH 6.0 with 1 N HCl and applied to an LC-18 solid-phase extraction column Supelco; Supelco Inc. ; .

Despite this, the current medications, both the first-generation drugs like haloperidol and the second-generation compounds like clozapine, risperidone, and olanzapine are part of the everyday armamentaria of psychiatrists in treating with persons with psychosis and omeprazole. Ziprasidone and QTc Prolongation Sir: We read with great interest Dr. Sharif's report about the safety of antipsychotics in primary care.1 He states that ziprasidone and thioridazine caused a clinically significant increase of QTc. An open-label, parallel-group phase 1 study 054 study ; 2 found that mean QTc increases were comparable for ziprasidone and 4 other antipsychotics--haloperidol, quetiapine, risperidone, and olanzapine--at maximum steadystate plasma concentrations. In this study, 2 no cardiovascular symptoms or QTc 500 ms were observed. The U.S. Food and Drug Administration has used QTc intervals 500 ms as a clinically significant cutoff. Therefore, although ziprasidone, as well as other antipsychotics haloperidol, quetiapine, risperidone, and olanzapine ; , increases the QTc, this increase is not clinically significant. Apart from this, ziprasidone has not been associated with torsades de pointes, sudden death, or increased cardiac mortality.3.
