Efavirenz (EFV), a non-nucleoside reverse transcriptase inhibitor (NNRTI), is part of first-line therapy for the treatment of human immunodeficiency virus type 1 infection (HIV-1/AIDS). This drug shows relatively low oral absorption and bioavailability, as well as high intra- and inter-subject variability. Several studies have shown that treatment failure and adverse effects are associated with low and high EFV plasma concentrations, respectively. Some studies suggest different EFV formulations to minimize inter-patient variability and improve its solubility and dissolution; however, all of these formulations are complex, using for instance, cyclodextrins, dendrimers and polymeric nanoparticles, rendering them inviable industrially...

The critical factor considered in a depression induced by diabetes is the inflammation eliciting hippocampal, amygdala and thalamic neuronal injury. Therefore, inhibiting inflammatory reactions in the brain and reducing neuronal injury can alleviate depression in rodents suffering from diabetes mellitus. The oral administration of astaxanthin has been employed in emotional disorders and diabetic complications due to its anti-depressant, anti-inflammatory and anti-apoptotic functions. However, it has not been reported whether astaxanthin can improve diabetes-related depression-like behavior, and its potential mechanisms have not been elucidated...

Robert G Wahler, Alfred T Reiman, Joshua V Schrader
BACKGROUND: Pseudobulbar affect (PBA) consists of unprovoked and uncontrollable episodes of laughing and/or crying. In end-of-life situations, PBA symptoms can be especially distressing to family and friends during an already heightened emotional time. Although a commercial product combining dextromethorphan and quinidine (DMQ) is FDA approved for use in PBA, many hospice patients are unable to swallow any solids or semisolids. An alternative formulation for these patients is needed. OBJECTIVE: We present here two cases in which we used a compounded DMQ suspension successfully to treat PBA symptoms in the weeks before the patients' death...
