Di pasaran, terdapat berbagai sediaan obat yang mengkombinasikan dua atau lebih zat aktif dalam satu sediaan, salah satunya adalah obat flu yang mengandung parasetamol, klorfeniramin maleat, gliseril guaiakolat dan fenilefrin hidroklorida. Penelitian ini bertujuan untuk menetapkan kadar keempat campuran zat aktif tersebut secara simultan karena analisis keempat campuran zat aktif tersebut belum ditemukan baik di Farmakope Indonesia maupun di United States Pharmacopoeia. Penelitian dilakukan dengan mengoptimasi berbagai jenis campuran fase gerak yaitu metanol dengan buffer fosfat pH 4,1; metanol dengan buffer fosfat pH 4,3 dan metanol dengan buffer fosfat pH 4,6. Selain itu juga dilakukan optimasi berbagai perbandingan fase gerak yaitu 30:70; 40:60; 50:50; 60:40 dan 70:30. Hasil penelitian menunjukkan bahwa kombinasi fase gerak metanol:buffer fosfat pH 4,3 dengan perbandingan fase gerak 60:40; laju alir 1 ml/menit dan dideteksi pada panjang gelombang 263 nm dapat digunakan untuk menetapkan kadar parasetamol, klorfeniramin maleat, gliseril guaiakolat dan fenilefrin hidroklorida secara KCKT. Hasil kadar pada sediaan tablet Supraflu® memenuhi persyaratan yaitu diperoleh kadar fenilefrin HCl, parasetamol, gliseril guaiakolat dan klorfeniramin maleat berturutturut adalah 99,2362% ± 0,4493%; 96,0242% ± 0,2180%; 97,9870% ± 0,7435% dan 101.4191% ± 0,7106%. There are numerous drug preparations that consist two or more active substances in a fixed combination dosage form . One of them is flu remedies containing paracetamol, chlorpheniramine maleate, glycerylguaiacolate, and phenylephrine hydrochloride. This study aimed to determine the levels of the four mixtures of active substances simultaneously because the analysis of the four mixtures of active substances had not been found either in Indonesian Pharmacopoeia or in the United States Pharmacopoeia. The study was conducted by optimizing various types of mobile phase mixtures, i.e. methanol-phosphate buffer at pH 4.1, methanol- phosphate buffer at pH 4.3, and methanol-phosphate buffer at pH 4.6. Besides that, optimization of various mobilephase ratios were also conducted, i.e. 30:70; 40:60; 50:50; 60:40 and 70:30. The results showed that the mobilephase combination of methanol-phosphate buffer at pH 4.3 with a mobilephase ratio of 60:40; flow rate of 1 ml/minute and detection wavelength at 263 nm could be used to determine the levels of paracetamol, chlorpheniramine maleate, glycerylguaiacolate, and phenylephrine hydrochloride using HPLC. The results of the levels in Supraflu® tablet preparations met the requirements, where levels of phenylephrine HCl, paracetamol, glycerylguaiacolate and chlorpheniraminemaleate   were 99.2362% ± 0.4493%; 96,0242% ± 0,2180%; 97.9870% ± 0.7435% and 101.4191% ± 0.7106%, respectively.

Background:The concept of green analytical chemistry prevails due to the growing environmental pollution.Objective:Our attempts are to develop simple and eco-friendly method which is non-harmful to the environment by producing minimal waste. In this context, a green liquid chromatographic method was applied for the simultaneous determination of chlorpheniramine maleate, pseudoephedrine hydrochloride and propyphenazone in their combined dosage form.Methods:Separation was carried out using X select HSS RP C18 analytical column (250 × 4.6 mm, 5μm) using methanol - 0.02 M phosphate buffer pH 3 - triethylamine (60:40: 0.1, by volume) as a mobile phase. The separated peaks were detected at 215 nm at a flow rate 1.0 mL/min.Results:Quantification was done over the concentration ranges of 1-25 µg/mL for chlorpheniramine maleate, 5-35 µg/mL for pseudoephedrine hydrochloride and 10-120 µg/mL for propyphenazone. The suggested method was validated with regard to linearity, accuracy and precision according to the International Conference on Harmonization guidelines with good results.Conclusion:It could be used as a safer alternative for routine analysis of the mentioned drugs in quality control laboratories.

Abstract Background Clinical studies have reported inconsistent outcomes of glucosamine therapy in osteoarthritis patients. One possible reason could be the use of glucosamine products of varying quality. Objective Hence, this study aimed to assess the quality of glucosamine products marketed in Australia and India. This is the first study to investigate both the content and dissolution profiles of glucosamine products. Method The content and dissolution analysis of Australian (n = 25 brands) and Indian (n = 21 brands) glucosamine products was performed according to the criteria specified in the United States Pharmacopoeia (USP). Results The quality analysis revealed that 16% and 18% of Australian brands, as well as 24% and 19% of Indian brands, did not fulfil the USP content and dissolution criteria, respectively. In approximately half of these cases, the glucosamine content was only slightly below (<3%) that specified by the USP and dissolution was achieved within 15 min after the duration specified by the USP. Conclusions The majority of the brands did meet both the content and dissolution analysis criteria of the USP. The extent of deviation from the specified criteria for the other brands was probably insufficient to account for the significant variability in clinical effects. Hence, the study proposed that inter-patient pharmacokinetic variations in glucosamine could be another potential reason for inconsistent therapeutic effects. Highlights
