Can severe cardiorespiratory dysregulation induced by clozapine monotherapy be predicted?

Severe orthostatic and cardiorespiratory dysregulation may occur during institution of clozapine therapy both during concomitant benzodiazepine medication and on reinstitution of clozapine after a washout period. Extensive medical and neurological workup before and after the trials can nevertheless be normal. The absence of similar previous reactions to other drugs, adhering to monotherapy with clozapine, increasing dosage slowly or performing a single test for orthostatic reactions after initiating clozapine are insufficient precautionary measures.

Thrice-daily blood pressure readings on sotalol in the treatment of hypertension: once- versus twice-daily regimen.

Thirty patients with mild to severe essential hypertension satisfactorily controlled by twice-daily sotalol therapy entered a double-blind, crossover study comparing the efficacy, tolerability, and safety of their usual twice-daily sotalol administration with the same dosage given once daily. Each double-blind period extended eight weeks, during which blood pressure and pulse rate were recorded by a nurse three times daily on alternate days during the last week of each period in the patients' usual living conditions. Plasma sotalol concentration was measured before the morning dosage of sotalol.

Comparison of once and twice daily administration of sotalol in the treatment of hypertension.

Thirty patients with mild to sever essential hypertension, satisfactorily controlled by twice daily Sotalol 80 to 320mg/day, entered a double-blind, crossover study comparing the efficacy, tolerability and safety of their usual twice daily dose of Sotalol with the same total dose given once a daily. Each double-blind period was eight weeks long; during it blood pressure and pulse rate were measured in each patient's home at 8-10 a.m.
