Abstract

Pinazepam (P) (10 mg) was orally administered to two young (22-23 years) and two elderly (74-80 years) healthy volunteers. Also, desmethyldiazepam (DD) (10 mg) was orally administered to the same young volunteers on a separate occasion. P was almost completely converted into DD 24 h after administration. Plasma levels of DD were measured in all subjects. In all cases, the DD concentration-time curve showed a biphasic decay (a first slow decay was followed by a fast one) which closely fitted by a Michaelis-Menten equation. Vmax and km constant were computed for all subjects. The kinetic analysis relative to the young subjects showed that T 1/2 of both the slow and fast decay as well as the area under the curve (AUC) were reduced when P was administered instead of DD. Comparison of DD kinetics between young and elderly subjects showed an increase of half-life in the elderly, while AUC was found unchanged.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 January 2023.
All research outputs
#7,608,793
of 23,197,711 outputs
Outputs from European Journal of Drug Metabolism and Pharmacokinetics
#95
of 427 outputs
Outputs of similar age
#5,336
of 30,577 outputs
Outputs of similar age from European Journal of Drug Metabolism and Pharmacokinetics
#1
of 2 outputs
Altmetric has tracked 23,197,711 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 427 research outputs from this source. They receive a mean Attention Score of 3.4. This one is in the 37th percentile – i.e., 37% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 30,577 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 2 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
