    EUROPEAN JOURNAL OF SCIENTIFIC EXPLORATION VOL 3 №2 2020 Determination of Oligomer Content in Benzonatate Drug Substance by HPLC Lakshmi Narasimha Rao Katakam 1 Santhosh Kumar Ettaboina 2 Thirupathi Dongala 2 1Saptalis Pharmaceuticals LLC, New York, USA 2Aurex Pharmaceuticals Inc, East Windsor, USA Abstract. A reverse-phase liquid chromatographic method has developed and validated to determine oligomer content in Benzonatate Drug substances. This method has a separation of relatively few monomer units, which constitutes an oligomer with a minimum adequate chromatographic resolution of 1.0 from each of the subject component peaks. The separation achieved using Phenomenex Luna C18 (250 X 4.6 mm) 5 µm column at a flow rate of 1.0 ml/min with an isocratic elution method. The mobile phase consisting of 0.25% Ammonium formate buffer and methanol in the ratio 350:650 (v/v), respectively. The Oligomer compounds detection carried out at UV 310 nm, and the LC method validated as per the current ICH Q2 guidelines. The method is effectively validated and proved to be precise, specific, linear, robust, and rugged to quantitate oligomer content in Benzonatate drug substance. Key words: benzonatate (BNZ), oligomers, HPLC, method validation. Introduction Benzonatate (BNZ) is an oral antitussive drug used to relieve and suppress cough in patients older than ten years of age (Oligomer Wikipedia, 2020). Currently, BNZ is the only non-narcotic antitussive available as a prescription drug. The chemical structure resembles that of the anesthetic agents in the para-amino-benzoic acid class (such as procaine and tetracaine), BNZ exhibits anesthetic or numbing action. BNZ also inhibits the transmission of impulses of the cough reflex in the medulla's vagal nuclei (Tessalon, 2020).

Upon administration, tanibirumab specifically binds to VEGFR2, thereby preventing the binding of its ligand VEGF. This may result in the inhibition of tumor angiogenesis and a decrease in tumor nutrient supply. VEGFR2 is a pro-angiogenic growth factor receptor tyrosine kinase expressed by endothelial cells, while VEGF is overexpressed in many tumors and is correlated to tumor progression.
