OBJECTIVE Intracranial hypertension (ICH) remains the single most difficult therapeutic challenge for the acute management of severe traumatic brain injury (TBI). We reviewed the published trials of therapeutic moderate hypothermia to determine its effect on ICH and compared its efficacy to other commonly used therapies for ICH. METHODS A PubMed database search was done using various combinat...

Classical Barbiturates are formed by substituting one or both hydrogen atoms at the 5-position with alkyl, aryl, and/or alicyclic groups. In this study, a previously developed UPPER (Unified Physicochemical Property Estimation Relationships) approach is applied to predict the melting points and aqueous solubilities of a series of barbiturates. The descriptors from a previously developed UPPER m...

INTRODUCTION There are many common drugs which have significant sedative-hypnotic properties. Alcohol and barbiturates have been discussed separately in this appendix, and their many pharmacological similarities were indicated. Barbiturates are often considered the prototype of sedative-hypnotic drugs; pharmacologically related compounds are frequently identified or discussed in terms of their ...

In this study, an established HPLC method for USP Phenobarbital was sequentially and quickly improved to a high throughput method using Rapid Resolution (RR) and Rapid Resolution High Throughput (RRHT) techniques. New RRHT column technology is an especially powerful tool for improving lab productivity by reducing HPLC analysis time dramatically. Starting with a proven rugged method, conversion ...

Knoevenagel condensation between barbituric acid and aldehyde was investigated in the presence of sulfonic acid functionalized nanoporous silica (SBA-Pr-SO3H) and resulted in the formation of arylidene and bis-arylidene barbiturates. Excellent yields and short reaction times are related to the high efficiency of SBA-Pr-SO3H that the reactions take place easily in its nano-pores. SBA-Pr-SO3H as ...
