Jak czytać widmo IR
  • 3200-3600 cm⁻¹ — rozciąganie O-H (szeroki pik = wiązanie wodorowe)
  • 2850-3000 cm⁻¹ — rozciąganie C-H (sp³)
  • 1650-1750 cm⁻¹ — rozciąganie C=O (ketony, aldehydy, estry)
  • 1400-1600 cm⁻¹ — drgania pierścienia aromatycznego
  • 1000-1300 cm⁻¹ — rozciąganie C-O (etery, alkohole)
  • Brak absorpcji = brak grupy funkcyjnej → porównaj z referencją

A rapid and stability-indicating reversed phase high-performance liquid chromatography (RP-HPLC) method was developed for simultaneous quantification of paracetamol and ibuprofen in their combined dosage form especially to get some more advantages over other methods already developed for this combination. The method was validated according to United States Pharmacopeia (USP) guideline with respect to accuracy, precision, specificity, linearity, solution stability, robustness, sensitivity, and system suitability. Forced degradation study was validated according to International Conference on Harmonisation (ICH). For this, an isocratic condition of mobile phase comprising phosphate buffer (pH 6.8) and acetonitrile in a ratio of 65:35, v/v at a flow rate of 0.7 mL/minute over RP C18 (octadecylsilane (ODS), 150 × 4.6 mm, 5 μm, Phenomenex Inc.) column at ambient temperature was maintained. The method showed excellent linear response with correlation coefficient (R2) values of 0.999 and 1.0 for paracetamol and ibuprofen respectively, which were within the limit of correlation coefficient (R2 > 0.995). The percent recoveries for two drugs were found within the acceptance limit of (97.0–103.0%). Intra-and inter-day precision studies of the new method were less than the maximum allowable limit percentage of relative standard deviation (%RSD) ≤ 2.0. Forced degradation of the drug product was carried out as per the ICH guidelines with a view to establishing the stability-indicating property of this method and providing useful information about the degradation pathways, degradation products, and how the quality of a drug substance and drug product changes with time under the influence of various stressing conditions. The degradation of ibuprofen was within the limit (5–20%, according to the guideline of ICH), while paracetamol showed <20% degradation in oxidation and basic condition.

🔗 DOI🏠 PMC📚 PubMed📄 PDF
Paracetamol (acetaminophen) (PAR), caffeine (CAF) and tramadol hydrochloride (TRA) are important drugs widely used for many clinical purposes. Determination of their contents is of the paramount interest. In this respect, a quick, simple and sensitive isocratic RP-HPLC method with photodiode array detection was developed for the determination of paracetamol, caffeine and tramadol in pharmaceutical formulations. An improved sensitive procedure was also evolved for tramadol using a fluorescence detector system. A C18 column and a mobile phase constituted by methanol/phosphate were used. LODs were found to be 0.2 μg/mL, 0.1 μg/mL and 0.3 μg/mL for paracetamol, caffeine and tramadol hydrochloride, respectively, using photodiode-array detection. Alternatively, LOD for tramadol decreased to 0.1 μg/mL with the fluorescence detector. Other notable analytical figures of merit include the linear concentration ranges, 0.8–270 μg/mL, 0.4–250 μg/mL and 1.0–300 (0.2–40) μg/mL, for the same ordered analytes (including the fluorescence detector). The proposed method was successfully applied for the quantitative determination of the three drugs in tablet dosage forms.

SummaryLapatinib is a tyrosine kinase inhibitor used for the treatment of breast cancer. Paracetamol is an analgesic commonly applied to patients with mild or moderate pain and fever. Cancer patients are polymedicated, which involves high risk of drug interactions during therapy. The aim of the study was to assess the interaction between lapatinib and paracetamol in rats. The rats were divided into three groups of eight animals in each. One group received lapatinib + paracetamol (IL + PA), another group received lapatinib (IIL), whereas the last group received paracetamol (IIIPA). A single dose of lapatinib (100 mg/kg b.w.) and paracetamol (100 mg/kg b.w.) was administered orally. Plasma concentrations of lapatinib, paracetamol and its metabolites – glucuronide and sulphate, were measured with the validated HPLC-MS/MS method and HPLC-UV method, respectively. The pharmacokinetic parameters of both drugs were calculated using non-compartmental methods. The co-administration of lapatinib and paracetamol increased the area under the plasma concentration-time curve (AUC) and the maximum concentration (Cmax) of lapatinib by 239.6% (p = 0.0030) and 184% (p = 0.0011), respectively. Lapatinib decreased the paracetamol AUC0-∞ by 48.8% and Cmax by 55.7%. In the IL + PA group the Cmax of paracetamol glucuronide was reduced, whereas the Cmax of paracetamol sulphate was higher than in the IIIPA group. Paracetamol significantly affected the enhanced plasma exposure of lapatinib. Additionally, lapatinib reduced the concentrations of paracetamol. The co-administration of lapatinib decreased the paracetamol glucuronidation but increased the sulphation. The findings of this study may be of clinical relevance to patients requiring analgesic therapy.

📚 Technische FAQ — acetaminophen (5) MolGod_TECHFAQ_1
❓ Jak przygotować roztwór standardowy paracetamolu o stężeniu 10 mg/mL?
MolGod_TECHFAQ_1_Q0
Aby przygotować roztwór standardowy paracetamolu o stężeniu 10 mg/mL, należy odważyć dokładnie 15.12 mg (10 mg / 1 mL * 1 mol / 151.16 g) substancji czynnej i rozpuścić w około 1 mL rozpuszczalnika (np. metanolu lub wody destylowanej). Następnie uzupełnić do objętości 10 mL za pomocą odpowiedniego rozpuszczalnika, np. buforu fosforanowego pH 7.4.
Hilfreich?
❓ W jakich warunkach należy przechowywać paracetamol w laboratorium?
MolGod_TECHFAQ_1_Q1
Paracetamol powinien być przechowywany w temperaturze pokojowej (15-25°C), z dala od bezpośredniego światła słonecznego i źródeł ciepła. Wilgotność względna nie powinna przekraczać 65%. Zaleca się przechowywanie w szczelnie zamkniętym pojemniku z ciemnego szkła lub tworzywa sztucznego odpornego na rozpuszczalniki organiczne.
Hilfreich?
❓ Jaka metoda analityczna jest najbardziej odpowiednia do oznaczania paracetamolu w próbce?
MolGod_TECHFAQ_1_Q2
Najczęściej stosowaną metodą analityczną dla paracetamolu jest wysokosprawna chromatografia cieczowa (HPLC) z detektorem UV przy 247 nm lub 254 nm. Metoda ta pozwala na dokładne oznaczenie stężenia substancji dzięki jej dobrej rozpuszczalności w odpowiednich rozpuszczalnikach i stabilności termicznej.
Hilfreich?
❓ Jakie są potencjalne niezgodności chemiczne paracetamolu z innymi substancjami?
MolGod_TECHFAQ_1_Q3
Paracetamol może wchodzić w reakcje z silnymi utleniaczami (np. nadtlenkiem wodoru), kwasami nieorganicznymi (np. kwasem siarkowym) oraz zasadami mocnymi (np. NaOH). Nie należy go również przechowywać w obecności reduktorów, takich jak DMSO czy TCEP, które mogą prowadzić do jego degradacji. Zaleca się stosowanie buforu fosforanowego pH 7.4 jako bezpiecznego środowiska.
Hilfreich?
❓ W jakim praktycznym zastosowaniu laboratoryjnym wykorzystuje się paracetamol?
MolGod_TECHFAQ_1_Q4
Paracetamol jest często używany w laboratoriach farmaceutycznych i analitycznych jako wzorzec do kalibracji metod HPLC oraz jako substancja badana w testach stabilności leków. Ponadto, ze względu na swoje właściwości przeciwbólowe i przeciwgorączkowe, bywa stosowany w badaniach biologicznych dotyczących mechanizmów działania leków przeciwbólowych.

  • Warfaryna
    UmiarkowaneEL: A
    CAS partnera: 81-81-2 · DrugBank DB00682 · PubChem 54678486

    Mechanizm: Paracetamol w dawkach kumulacyjnych > 2 g/d przez ≥ 7 dni hamuje cykl K-witaminy (zaburza metabolizm warfaryny przez NAPQI i hamowanie VKORC1).

    Skutek kliniczny: Wzrost INR o 1–3 jednostki; istotnie zwiększone ryzyko krwawienia.

    Postępowanie: Ograniczyć paracetamol do ≤ 2 g/d przy stałej terapii warfaryną. Sprawdzić INR po 3–5 dniach od zwiększenia dawki paracetamolu.
