Trazodone succinate — new opportunities for pharmacological correction of situational behavioral abnormalities in dogs and cats

Currently, the interest of veterinarians and owners in the pharmacological correction of situational behavioral disorders in companion animals has increased significantly. To quickly correct deviant behavior in dogs and cats, veterinarians use some of the psychotropic drugs used in humane medicine, in particular, trazodone, an antidepressant antagonist / serotonin reuptake inhibitor. Based on the analysis of literature sources, data on the history of creation and pharmacological properties, assessment of the safety and efficacy of drugs based on trazodone hydrochloride in behavioral medicine of small pets are provided. The data on the prerequisites for the development, pharmaco-toxicological and clinical evaluation of a new drug for the modification of abnormal behavior in dogs and cats, Express Uspokoin® tablets based on trazodone succinate, which, with a high efficiency of the target action, made it possible to achieve the absence of side effects and significantly increase the tolerance of the dosage form by animals, are analyzed. compared with preparations based on trazodone hydrochloride.

FORMULATION DEVELOPMENT AND EVALUATION OF MATRIX TABLET TRAZODONE HYDROCHLORIDE USING NATURAL POLYMER

Increased complications and costs of marketing of innovative drugs focused greater attention to the development of sustained release (SR) or controlled release (CR) drug delivery systems. Trazodone Hydrochloride (TRZ) is a well-known chemical compound that is used as an antidepressant that belongs to a selective serotonin reuptake inhibitor (SARI). The objective of present work was to develop and evaluated oral sustained release matrix tablet of TRZ. Pre-compression parameters were evaluated. The tablets were evaluated for post-compression parameters such as thickness, hardness, average weight, friability and In vitro release studies. No interactions were observed between TRZ and excipients from the Fourier transform infrared spectroscopy. The present research work was successful in improving the efficacy TRZ oral therapy as the drug release was extended for 12 hours thus reducing dosing frequency thereby improving patient compliance. The study also revealed the applicability of HPMC K-15, Gaur gum and PVP K30 as rate-controlling polymers in matrix tablets. The hydrophilic matrix of HPMC alone cannot control the release TRZ effective for 12 h while when combined with guar gum, may slow down the release of the drug and therefore, can be successfully employed for the formulation of matrix tablets SR. It may be concluded from the study that; the optimized formulation F-8 was shown maximum drug release 99.12 % in 12 h of dissolution. The release kinetic data of formulation F-8 shown first order release kinetics (R2 = 0.980).

Improvement of Advanced Assisted gastro retentive floating tablet using TRZ and S

Definition advancement is a significant piece of medication plan and improvement. Bioavailability and bioequivalence are absolutely reliant on definition improvement. Presently a-days detailing advancement is finished by following Quality through Design. Floating drug conveyance frameworks are the gastro retentive structures that absolutely control the delivery pace of target medication to a particular site which encourage a tremendous effect on medical care. This can be accomplished by utilization of different polymeric substances. Trazodone-Hydrochloride (TRZ), is a notable substance aggravate that is utilized as an energizer that has a place with a particular serotonin repeated inhibitors (SARI). The delivery information was fitted to different numerical models, for example, higuchi, Korsmeyer-Peppas (KP), 1st request &0 request to assess the energy and system of the medication discharge. Arranged coasting tablets of TRZ may end up being a possible possibility for sheltered and successful controlled medication conveyance over an all-encompassing timeframe for gastro retentive medication conveyance framework. The oral assisted medication architecture conveyance has been confounded through confined habitation time gastric. Also, rapid gastro-intestinal transmission might predict overall discharge medication in zone of retention and diminish the handled portion adequacy, as many of medications have been invested on small digestive upper piece system. Also, it handles structure measurement at assimilation site & in this way updates bio-availability as stated in.

Luminescent determination of residues of trazodon hydrochloride and melatonin after cleaning pharmaceutical equipment

A prerequisite for ensuring the quality of medicines is their production in accordance with the rules of GMP (Good Manufacturing Practice for Medicinal Products), one of the most important requirements of which is equipment cleaning. In many cases, the same equipment is used in the production of various preparations. Therefore, to prevent contamination of each of the following drugs, the previous one, it is very important to carry out an effective equipment cleaning procedure with a mandatory assessment of its purity. The purpose of this study was to develop simple, express, selective methods for luminescent determination of residual quantities of APIs of trazodone hydrochloride (TG) and melatonin (MT) in washes to control the completeness of their removal when cleaning process equipment. The excitation and luminescence spectra were recorded using a Cary Eclipse "Varian" spectrofluorimeter (Australia) with a xenon lamp 150 W. Electronic absorption spectra were recorded on a UV-2401 PC spectrophotometer «Shimadzu» (Japan). The electronic absorption spectra of TG and MT have absorption bands in the UV spectral region. It was established experimentally that the excitation spectra of TG and MT are similar to their absorption spectra (λex = 318 nm (TG) and λem = 274 nm (MT)). The effect on the luminescence intensity of TG and MT of methanol, ethanol, acetonitrile, dimethylformamide, dimethylsulfoxide, propanol (50 v/v) was studied. It is established that the maximum luminescence is observed in water. The methods were validated according to the following parameters: specificity, linearity, accuracy, limit of quantitation. The degree of extraction of trazodone hydrochloride and melatonin from applicators and surfaces of pharmaceutical equipment is more than 90%. The developed methods can be recommended for determining the residual amounts of trazodone hydrochloride and melatonin while monitoring the quality of the cleaning of pharmaceutical equipment.
