Nonsedating muscle relaxant
Oral second generation antihistamines inhibit histamine dependent activation of nasal H1-receptors.They mainly reduce nasal itch, sneezing, and hypersecretion. Stimulants Many commonly used prescription and over-the-counter medications can impair driving performance.Medications that cause drowsiness, euphoria, and/or anterograde amnesia may also diminish insight, and the patient may experience impairment without being aware of it.Combinations of drugs may affect drug metabolism and excretion to produce additive or synergistic interactions.In fact, use of multiple psychoactive medications is a common cause of hospitalization for delirium among older adults. wine) has the potential to impair driving performance in many individuals.In addition, allergy related activity impairment is reduced resulting in improved physical and mental performance.
Some patients seem to prefer taking oral antihistamines to using a daily corticosteroid (e.g. Variations in symptoms while on a single antihistamine more than likely are due to differences in the natural course of the condition rather than tolerance to the drug in question. Results: Statistically significant inhibition of skin reaction (over 92%) and blood flow (over 85%) in relation to the start values in cetirizine group as well as between the groups which received cetirizine or placebo (p. Oral second generation antihistamines in allergic rhinitis].
In the case of these medications, the concerned physician and patient may wish to consider formal psychomotor testing (up to and including driving simulation) or driver evaluation (including on-road assessment) performed by a driver rehabilitation specialist, while off and on the medication to determine the extent of impairment.
When prescribing new medications, the physician should always consider the patient’s existing regimen of prescription and non-prescription medications, including medications taken seasonally.
Activation of H1-receptors on nasal trigeminal nerve fibers transmits nasal itch and sneezing.
Nasal hypersecretion is mainly mediated by an trigeminal-parasympathetic reflex.
