Abstract in Portuguese
A buspirona, ansiolítico da segunda geração usada no tratamento de ansiedade, foi analisada fisico-quimica e quimicamente, com o objetivo de fornecer subsídios para a respectiva monografia. Fizeram-se os seguintes testes de caracterização deste fármaco: faixa de fusão, análise elementar, pH, umidade e solubilidade. Realizaram-se igualmente as provas de identificação constante de: análise cromatográfica, ensaio de cloreto, espectro no infravermelho, espectro no ultravioleta, espectro de ressonância magnética protônica, espectro de massa, espectro de carbono-13, termogravimetria, calorimetria exploratória diferencial e cromatografia líquida de alta resolução. Efetuaram-se, também, determinações quantitativas pelos seguintes métodos: micro-Kjeldahl, gravimétrico, potenciométrico com nitrato de prata, doseamento com ácido perclórico em meio acetico por volumetria e potenciometria e espectrofotométrico no ultravioleta. Concluiu-se que: 1) o teste de caracterização mais indicado e o ponto de fusão; 2) das provas de identificação, as mais simples e rápidas são as seguintes: identificação de cloreto, infravermelho e ultravioleta; 3) dos métodos de determinação quantitativa, mais prático e o doseamento com ácido perclórico em meio acético, usando como indicador o vermelho de quinaldina.

Abstract in English
Buspirone, a new non-benzodiazepine anxiolytic agent which is effective in the treatment of anxiety, was analyzed by physicochemical and chemical methods, having in mind a monograph of this drug. The fo1lowing characterization tests of this drug were performed: melting range, elementary analysis, pH, loss in drying, solubility. The following identification tests were also carried out: chromatographic analysis, identification of chloride, infrared absorption, ultraviolet absorption, protonic magnetic resonance spectra, mass spectrum, carbon 13C NMR spectroscopy, thermogravimetry and high performance liquid chromatography. Quantitative determinations were obtained through the following methods: micro-Kjeldahl, gravimetry, potenciometry, non-aqueous titration with perchloric acid and ultraviolet spectrometry. The following conclusions were reached: 1) the best characterization test is the melting range; 2) the simplest and quickest tests of identification are: identification of chloride, infrared and ultraviolet spectrophotometry; 3) the most practical method is the non-aqueous assay with perchloric acid.
