Лаппаконитин представляет собой алкалоид, содержащийся в корнях и надземной части аконита белоустого (Aconitum leucostomum Vorosh.) и обладающий антиаритмическим действием. После приема препаратов лаппаконитина в организме человека образуется 8 изученных фармакологически активных метаболитов, наибольшую активность среди которых проявляет N-дезацетиллаппаконитин. Фармакокинетика препаратов лаппаконитина изучена недостаточно. Препараты лаппаконитина имеют узкий терапевтический диапазон и обладают большим количеством побочных эффектов, поэтому для оценки безопасности применения препаратов лаппаконитина возникает необходимость полноценного изучения его фармакокинетики.</p></sec><sec><title>Цель</title><p>Цель. Целью исследования является разработка методики определения лаппаконитина и его активного метаболита N-дезацетиллаппаконитина в плазме крови и в цельной крови человека методом высокоэффективной жидкостной хроматографии с тандемным масс-селективным детектированием (ВЭЖХ-МС/МС).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы.

Полученные аналитические диапазоны позволяют применять разработанную методику для проведения фармакокинетических исследований препаратов лаппаконитина.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Lappaconitine is an alkaloid, contained into Aconitum leucostomum Vorosh. roots and herbs. The alkaloid is indicated to arrhythmia. The lappaconitine drugs are metabolized into eight pharmacologically active substances, but N-desacetyllappaconitine is the most effective. Drugs based on a lappaconitine has narrow therapeutic range and many kinds of side effects. Pharmacokinetics of lappaconitine should be more studied for safety medical use of lappaconitine drugs.</p></sec><sec><title>Aim</title><p>Aim. The aim of this study is to develop method for the quantitative determination of lappaconitine and its active metabolite N-desacetyllappaconitine in human plasma and blood by high performance liquid chromatography and tandem mass spectrometry (HPLC-MS/MS).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Determination of lappaconitine and N-desacetyllappaconitine in plasma and blood was carried out by HPLC-MS/MS.

This method was validated by next parameters: selectivity, matrix effect, calibration curve, accuracy, precision, spike recovery, lower limit of quantification, carry-over effect and stability.</p></sec><sec><title>Conclusion</title><p>Conclusion. The method of the quantitative determination of lappaconitine and N-desacetyllappaconitine in human plasma and blood was developed and validated by HPLC-MS/MS. The analytical range of the was 0.50-50.00 ng/ml for lappaconitine and 0.50-100.00 ng/ml for N-desacetyllappaconitine in biological matrix. Method could be applied to determination of lappaconitine and N-desacetyllappaconitine for PK studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лаппаконитин</kwd><kwd>N-дезацетиллаппаконитин</kwd><kwd>плазма</kwd><kwd>кровь</kwd><kwd>ВЭЖХ-МС/МС</kwd><kwd>валидация</kwd><kwd>фармакокинетика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lappaconitine</kwd><kwd>N-desacetyllappaconitine</kwd><kwd>plasma</kwd><kwd>blood</kwd><kwd>HPLC-MS/MS</kwd><kwd>validation</kwd><kwd>pharmacokinetics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">WHO reveals leading causes of death and disability worldwide: 2000-2019.
