BACKGROUND: Patterns in general consumer online search logs have been used to monitor health conditions and to predict health-related activities, but the multiple contexts within which consumers perform online searches make significant associations difficult to interpret. Physician information-seeking behavior has typically been analyzed through survey-based approaches and literature reviews. Activity logs from health care professionals using online medical information resources are thus a valuable yet relatively untapped resource for large-scale medical surveillance...

OBJECTIVES: Depression is a rapidly growing issue in the United States. There are many drug classes that may be used to treat depression, including the selective serotonin-reuptake inhibitors (SSRIs) citalopram (Celexa®) and sertraline (Zoloft®), as well as the aminoketone bupropion (Wellbutrin®). However, therapeutic efficacy and treatment success is often variable, requiring changes in dosing regimens or drug selection. Methods for drug quantification can become important tools in the assessment of drug efficacy to optimize treatment regimens...

Active Pharmaceutical Ingredients (APIs) are released into aquatic ecosystems through discharged sewage wastewater. Antidepressants are among those APIs often detected in wastewater effluent and have been recently reported to cause foot detachment from the substrate in freshwater snails. We tested the effects of four commonly prescribed antidepressants {fluoxetine ("Prozac"), fluvoxamine ("Luvox"), venlafaxine ("Effexor"), and citalopram ("Celexa") on adhesion to the substrate in five species of marine snails, three from the Pacific coast (Chlorostoma funebralis, Nucella ostrina, Urosalpinx cinerea) and two species from the Atlantic coast (Tegula fasciatus and Lithopoma americanum) of North America representing three different gastropod families...

Previous reviews have focused on the potential cardiac toxicity of the racemic drug citalopram (Celexa(®)). Evaluating the safety of escitalopram (Lexapro(®)) is an important issue to consider, since it is the S-enantiomer of citalopram. Escitalopram has a small effect on the QTc interval. A prolonged QTc was seen in 2% to 14% of escitalopram overdose cases, without serious cardiac sequelae. The QTc prolongation effect of citalopram in beagle dogs has been attributed to the minor metabolite racemic didemethylcitalopram (DDCT)...

In August 2011, the U.S. Food and Drug Administration issued a drug safety communication that the antidepressant drug citalopram (Celexa®) should not be used at dosages greater than 40 mg per day (or greater than 20 mg per day for patients 60 and older) because higher doses have been associated with abnormal heart rhythms. Clinical studies using citalopram in patients with cardiac disease and in older patients do not confirm such a risk. The major metabolite of citalopram is demethylcitalopram, which is subsequently metabolized to the minor metabolite didemethylcitalopram (DDCT)...

In August 2011, the U.S. Food and Drug Administration issued a safety announcement that the antidepressant drug citalopram (Celexa(®)) should not be used at dosages greater than 40 mg per day (or greater than 20 mg per day for patients 60 and older) because it can cause abnormal changes in the electrical activity of the heart. This warning was based on the results of a "thorough QT/QTc study" of citalopram and on post-marketing reports of QT prolongation and torsade de pointes in some patients taking the drug...

BACKGROUND: Generic drugs are lower-cost versions of patent-expired brand-name medications. Bioequivalence is decreed when the 90% confidence intervals for the ratios of the generic to the reference compound for the area under the curve and maximum plasma concentration (C(max)) fall within a 0.80 to 1.25 range. The aim of the present pilot study was to compare the pharmacokinetic profiles of brand-name and generic formulations of citalopram and extended-release venlafaxine. METHOD: Effexor XR/Novo-venlafaxine XR 75 mg and Celexa/Gen-citalopram 40 mg were studied in a randomized crossover design...

Although a large literature supports the benefits of breastfeeding, this review suggests that breastfeeding is less common among postpartum depressed women, even though their infants benefit from the breastfeeding. Depressed mothers, in part, do not breastfeed because of their concern about potentially negative effects of antidepressants on their infants. Although sertraline (Zoloft) and paroxetine (Paxol) concentrations are not detectable in infants' sera, fluoxetine (Prozac) and citalopram (Celexa) do have detectable levels...

In the central nervous system (CNS) and in the periphery, specific proteins (transporters) are responsible for the regulation of the synaptic concentrations of the major monoamine neurotransmitters, noradrenaline (NE), serotonin (5-HT) and dopamine (DA). Several reports have shown that the expression of these transporters within the CNS may be altered in patients with certain neurodegenerative or neuropsychiatric disorders. Therefore, in the CNS the monoamine transporters are major targets for existing and developmental drugs...

Selective serotonin reuptake inhibitors (SSRIs) are neurologically active drugs that can contaminate surface waters and have the potential to negatively affect aquatic organisms. In this investigation, the 48-h acute toxicity of mixtures (binary and quaternary) of four common SSRIs (fluoxetine [Prozac], sertraline [Zoloft], paroxetine [Paxil], and citalopram [Celexa]) were determined in the daphnid Ceriodaphnia dubia. Logistic regression was used to model mortality data and to investigate the applicability of concentration addition and independent action models to explain observed mortality...

Generic agents do not require large clinical trials of safety and efficacy to enter the market, although they must demonstrate both pharmacological and bioequivalence to the brand name drug. Bioequivalence is attained when the extent of absorption of the generic falls within an FDA predefined range relative to the brand name drug. This potential variation in bioequivalence is not thought to be clinically meaningful, however, there are reports of a lack of therapeutic equivalence between some generic medications and the brand name...

Very little is known about antidepressant medication use among First Nations people in Canada. This information would be useful to begin estimating the prevalence of conditions treated with this class of medications and planning appropriate programs. Antidepressant medication claims for First Nations people residing within British Columbia were extracted from the Non-Insured Health Benefits pharmacy database. During 2001, 9.8% (95% CI = 9.81, 9.79) of the population filled a prescription for antidepressant pharmacotherapy, claimant mean age was 40...

Contamination of surface waters by pharmaceutical chemicals has raised concern among environmental scientists because of the potential for negative effects on aquatic organisms. Of particular importance are pharmaceutical compounds that affect the nervous or endocrine systems because effects on aquatic organisms are possible at low environmental concentrations. Selective serotonin reuptake inhibitors (SSRIs) are drugs used to treat clinical depression in humans, and have been detected in low concentrations in surface waters...

The potency of escitalopram ("Lexapro," s-citalopram, LU-26-054) was compared with that of racemic citalopram ("Celexa") using plasma samples from drug-treated normal controls applied to an assay of human serotonin [5-hydroxytryptamine (5-HT)] transport inhibition in blood platelets. Samples were available for both 4-hour and 24-day drug administration. The data indicated that 5-HT transport inhibition was fully manifest for each drug within 4 hours of administration, without significant increase in platelet transport inhibition by 24-day treatment...
