摘要: Abstract This paper presents different HPLC methods for the simultaneous determination of some guaiphenesin-containing cough-cold preparations. Three pharmaceutically available combinations were analyzed: salbutamol sulfate (SAL) and guaiphenesin (GUA), combination I; ascorbic acid (ASC), paracetamol (PAR) II; theophylline anhydrous (THE), (GUA) ambroxol hydrochloride (AMB), III. A 250 × 4.6 mm C-18 column was used all combinations. The mobile phase three consisted a mixture methanol 0.01 M aqueous phosphate buffer solution. pH adjusted to 3.2, 6.2 3.8 I, II III, respectively. proposed successfully applied investigated drugs, both in synthetic mixtures pharmaceutical preparations, without any matrix interference with high precision accuracy. Different aspects analytical validation are presented text.
