And sedating

Fortunately, the child eventually recovered without any on-going ill-effects.Sedating antihistamines have the ability to cross the blood-brain barrier, the ability to bind to non-histamine receptors and have less selectivity for peripheral or central H1-receptors.Therefore it was difficult to find out the exact effects of these drugs on patients with as measured by the numbers and duration of pauses in breathing during sleep.In small, single-night studies, zolpidem 20 mg, flurazepam 20 mg and triazolam 0.25 mg showed a tendency to increase numbers and duration of pauses during sleep, which was not as measured by the numbers and duration of pauses in breathing during sleep, but significant clinical and statistical decreases in minimum oxygen levels during the night were observed with remifentanil, zolpidem and triazolam; therefore prescribing these drugs for patients with (remifentanil); some studies included CPAP treatment, whilst in a significant number of participants, previous treatment with CPAP was not stated and thus a residual treatment effect of CPAP could not be excluded.Findings/Results: Heterogeneity among the different antipsychotics regarding activating or sedating adverse events was observed, with some agents displaying the potential for both activating and sedating properties.For agents indicated for the treatment of schizophrenia, predominantly activating medications include lurasidone (NNH, 11 for akathisia vs 20 for somnolence) and cariprazine (NNH, 15 for akathisia vs 65 for somnolence-combined terms).Sedating antihistamines also have significant antimuscarinic activity and should be used with caution in patients with prostatic hypertrophy, urinary retention and angle-closure glaucoma.Examples of sedating antihistamines: Sedation is rare with non-sedating antihistamines, however patients should be made aware that a sedative effect may occur and performance of skilled tasks such as operating machinery or driving maybe affected.

For major depressive disorder, the overall findings regarding activation and sedation appear similar to those seen with schizophrenia.The most common adverse effects with sedating antihistamines are sedation, dizziness and incoordination.However, paradoxical stimulation ranging from excitation through to tremors, hallucinations and convulsions may occur.Implications/Conclusions: Differences in tolerability profiles regarding activation and sedation have implications in terms of selecting the optimal antipsychotic for a given individual.From the Department of Psychiatry & Behavioral Sciences, New York Medical College, Valhalla, NY.
