Chronic inducible urticaria: classification and prominent features of physical and non-physical types.
Authors: Pozderac I, Lugović-Mihić L, Artuković M, Stipić-Marković A, Kuna M, Ferček I Abstract Chronic inducible urticaria (CIndU) is a common inflammatory skin condition characterized by the recurrence of itchy wheals and/or angioedema that lasts more than 6 weeks and is induced by specific physical or environmental stimuli (cold, heat, exercise, pressure, sunlight, vibration, water, etc.). According to the current international classification, it includes physical urticarias (dermographism, delayed-pressure urticaria, exercise-induced urticaria, cold urticaria, heat urticaria, solar urticaria, and...

Elucidation of Degradation Behavior of Tricyclic Antidepressant Amoxapine in Artificial Gastric Juice.
Abstract The degradation behavior of eight tricyclic antidepressants (TCAs; amitriptyline, amoxapine (AMX), imipramine, clomipramine, desipramine, doxepin, dothiepin, and nortriptyline) in artificial gastric juice was investigated to estimate their pharmacokinetics in the stomach. As a result, among the eight TCAs, only AMX was degraded in artificial gastric juice. The degradation was a pseudo first-order reaction; activation energy (Ea) was 88.70 kJ/mol and activation entropy (ΔS) was -80.73 J/K·mol. On the other hand, the recovery experiment revealed that the degradation product did not revert to A...

Use of antidepressants with pharmacogenetic prescribing guidelines in a 10-year depression cohort of adult primary care patients
Conclusion One-quarter of primary care patients used an antidepressant that was not recommended for them based on CYP2D6- and CYP2C19-based prescribing guidelines and switching medications tended to be more common in this group. Studies to determine the impact of CYP2D6 and CYP2C19 genotyping on reducing gene-antidepressant mismatches are warranted. (Source: Pharmacogenetics and Genomics)

Roles of Lys191 and Lys179 in regulating thermodynamic binding forces of ligands to determine their binding affinity for human histamine H1 receptors.
In this study, we evaluated the roles of Lys1915.39 and Lys179ECL2 in regulating the thermodynamic binding forces of non-carboxylated and carboxylated antihistamines that determine their binding affinity for human H1 receptors. The binding enthalpy and entropy of the 3 sets of non-carboxylated and corresponding carboxylated antihistamines (doxepin and olopatadine, desloratadine and loratadine, and terfenadine and fexofenadine, respectively) were estimated using the van't Hoff equation with the dissociation constants obtained from the displacement curves of the non-carboxylated and carboxylated antihistamines against the bi...

Optimizing doxepin therapy in dermatology: Introducing blood level monitoring and genotype testing.
Authors: Myers B, Reddy V, Chan S, Thibodeaux Q, Brownstone N, Koo J Abstract Doxepin, a tricyclic antidepressant, is the most efficacious antipruritic available to dermatologists, however its use is often suboptimal because of significant interindividual variability in doxepin plasma levels and clinical response between patients taking the same dose. As result, the Food and Drug Administration approves a maximum dose of 300 mg of doxepin per day and a 10 mg per cc liquid doxepin concentrate. These allow patients to significantly increase or decrease their dose, due to either a lack of clinical efficac...

Antidepressant Prescribing in England: Patterns and Costs.
Conclusions: Broadly, the findings are in keeping with National Institute for Health and Care Excellence guidance in that the bulk of prescriptions were for SSRIs. Regular audit of patient treatment at a general practice level will ensure appropriate targeted use of licensed medications as supported by the evidence base.

High-throughput protein precipitation method with 96-well plate for determination of Doxepin and Nordoxepin in human plasma by LC-MS/MS.
Abstract The aim of this study was to establish high-throughput and sensitive liquid chromatography tandem mass spectrometry method for the determination of Doxepin and its major active metabolite Nordoxepin in human plasma. It has been designed for bioequivalence study for formulations containing 25 mg of Doxepin. Doxepin and Nordoxepin were extracted from human plasma samples by protein precipitation (PPT) with acetonitrile by using PPT 96-well plates. Analyte separation was done using Phenomenex Kinetex™ Biphenyl (100 x 2.1 mm, 2.6 μm) column using isocratic elution with a mobile phase of 20 mM ammon...

Supramolecular microextraction combined with paper spray ionization mass spectrometry for sensitive determination of tricyclic antidepressants in urine.
Abstract This work describes a novel methodology to analyze four tricyclic antidepressants (amitriptyline, doxepin, imipramine and, nortriptyline) in urine samples by combining supramolecular microextraction and paper spray ionization mass spectrometry (PS-MS). The proposed method uses a supramolecular solvent in which reverse micelles of 1-decanol are dispersed in tetrahydrofuran (THF)/water. The extraction of the tricyclic antidepressants at pH 9.0 requires a sample volume of 10.0 mL, short extraction time (1.0 min of extraction and 5 min of centrifugation), low amounts of organic solvent (50 μL of ...
