Updated on 17 August 2020 SPC
Reasons for updating
- Change to section 5.3 - Preclinical safety data
Legal category: Product subject to medical prescription which may not be renewed (A)
Free text change information supplied by the pharmaceutical company
The SPC has been updated as follows:
To remove the previously approved wording in section 5.3 of the SmPC.
Effect of anesthetic and sedative drugs Nonclinical research has shown that administration of anesthetic and sedation drugs that block N-methyl-D-aspartate (NMDA) receptors and/or potentiate gamma-aminobutyric acid (GABA) activity can increase neuronal cell death in the brain and result in long term deficits in cognition and behavior of juvenile animals when administered during the period of peak brain development. Based on comparisons across nonclinical species, the window of vulnerability of the brain to these effects is believed to correlate with human exposures in the third trimester of pregnancy through the first year of life, but may extend to approximately 3 years of age. While there is limited information of this effect with triazolam, since the mechanism of action includes potentiation of GABA activity, a similar effect may occur. The relevance of these nonclinical findings to human use is unknown.
