Sedating effects of
This means that first-generation antihistamines are more likely to cause side effects such as sedation, dry mouth, dizziness, low blood pressure, and a rapid heart-beat.
However, there are a number of clues at a crash scene that tell investigators that the person fell asleep at the wheel.
They act on histamine-1 receptors in the periphery and are unlikely to penetrate the brain, so are less likely to cause side effects or interact with drugs.
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.
