Do higher preinfusion heart rates predict laboratory-induced panic attacks?

Baseline and preinfusion heart rates of 13 panic disorder patients who panicked during a placebo infusion were not significantly different from those of 57 panic disorder patients who did not panic during a placebo infusion. The change in preinfusion heart rates from baseline values also was not significantly different between the two groups.

Platelet monoamine oxidase activity in panic disorder.

Platelet monoamine oxidase (MAO) activity was studied in 21 patients meeting Research Diagnostic Criteria for panic disorder and in 12 healthy controls. Platelet MAO activity in females in both patient and control groups tended to be higher than that in males, but the results did not reach statistical significance. Platelet MAO activity was significantly decreased in panic disorder patients compared to controls.

Pre-infusion heart rates and laboratory-induced panic anxiety.

Resting and pre-infusion heart rates recorded in 66 panic disorder patients revealed no significant differences between panickers and nonpanickers. There was also no significant difference in pre-fusion heart rates between either lactate or isoproterenol panickers and placebo nonpanickers. There was neither a sensitizing nor a desensitizing effect of laboratory-induced panic attacks on subsequent pre-infusion heart rates.

Platelet serotonin levels in panic disorder.

Platelet serotonin levels were examined in 18 patients with panic disorder and compared to platelet serotonin levels of eight healthy controls. There was no statistically significant difference in the platelet serotonin levels between the two groups.

The effect of tricyclic antidepressants on stress-induced heart rate changes in panic disorder patients.

Eight panic disorder patients participated in a double-blind placebo-controlled infusion study designed to induce panic-anxiety in the laboratory both before and after treatment with tricyclic antidepressants. Pre-infusion heart rates for the first infusion were significantly higher than baseline both before and after treatment. The delta increase in pre-infusion heart rates from baseline and the ratios of pre-infusion heart rates to baseline values were not significantly different between before and after treatment conditions indicating similar levels of arousal during the two pre-infusion periods, while the pre-infusion anxiety ratings after treatment were significantly lower.

Allergy to tartrazine in antidepressants.

The authors describe five cases of apparent allergy to tartrazine (FD&C yellow dye number 5) in 170 patients exposed to the dye in antidepressants. The frequency of tartrazine sensitivity was much higher than the reported frequency of six in 1,000 persons.

Thrombocytopenia associated with chlorpromazine, haloperidol and thiothixene: a case report.

Hematological side effects of neuroleptic drugs occur infrequently but remain a potential cause of serious toxicity. A case of recurrent thrombocytopenia due to the repeated exposure to chlorpromazine (twice), haloperidol (four times) and thiothixene (twice) in a 59 year old female treated for schizophrenia is reported. Treatment difficulties and implications of this case are discussed.

A grand mal seizure associated with desipramine and haloperidol.

Authors describe a case of grand mal seizure associated with administration of desipramine and haloperidol. Neuroleptic induced inhibition of desipramine metabolism is discussed as a possible explanation of unusually high desipramine plasma level of 610 ng/ml at the day of seizure.

The effect of lithium on platelet count.

The effect of lithium on platelet count was studied by examining 12 patients treated with lithium carbonate without any additional medication, 13 patients treated with lithium carbonate with additional psychotropic medication, 25 patients with major affective disorder prior to any treatment, 25 patients with panic disorder prior to any treatment and 25 healthy controls. The platelet counts were increased in the group of subjects treated with lithium carbonate without any additional psychotropic medication. The increase was not clinically significant.
