1 International Journal of Innovative Pharmaceutical Sciences and Research ANALYTICAL METHOD DEVELOPMENT AND VALIDATION OF STABILITY INDICATING HPLC METHOD FOR ESTIMATION OF FIXED DOSAGE FORM OF ATROPINE SULPHATE, EPINEPHRINE BITARTARATE AND LIGNOCAINE HYDROCHLORIDE INJECTION 1 S.Abraham Jebaraj*, 2 R.Prasanna, 3 T.Sivakumar 1 Department of pharmaceutical Analysis, Karpagam university.coimbatore, INDIA 2 Adcock Ingram limited, Bangalore. INDIA 3 Prinicipal, Nandha college of pharmacy.erode. INDIA Abstract A Simple, Fast, precise, accurate stability indicating high performance liquid chromatography (HPLC) method has been developed for estimation of fixed dosage form of Atropine sulphate, Epinephrine bitartarate, Lignocaine hydrochloride injectable dosage form. The separation for lignocaine was obtained using a mobile phase composition at the ratio of 50:50 (v/v) of water and acetonitrile by adjusting ph 3.3 with ortho phosphoric acid on sunfire C18 Column (250 X4.6 mm, 5 µm ) with PDA detection at 254 nm at flow rate of 1 ml/min. The linear calibration was found to be for lignocaine. The separation for Epinephrine was obtained using a mobile phase composition at the ratio of 50:50 (v/v) of water and Methanol by adjusting to ph 3.2 with ortho phosphoric acid on sunfire C18 Column (250 X4.6 mm, 5 µm) with PDA detection at 280 nm at flow rate of 1 ml/min. The linear calibration was found to be for epinephrine. The separation for Atropine was obtained using a mobile phase composition at the ratio of 50:50 (v/v) of Methanol and water by adjusting ph 3.8 with ortho phosphoric acid on sunfire C18 Column (250 X4.6 mm, 5 µm ) with PDA detection at 229 nm at flow rate of 0.5 ml/min. The linear calibration was found to be for atropine. The method validation data showed excellent results for precision, linearity, specificity and robustness. The present method can be successfully used for routine quality control and stability studies. Keywords: Atropine, Epinephrine, Lignocaine, Injectable dosage, Precision, Linearity, Specificity.

2 INTRODUCTION Atropine sulphate a potent parasympatholytic agent for use in producing cycloplegia and mydriasis. Useful for cycloplegic refraction or for pupil dilation in acute inflammatory conditions of the iris and uveal tract. Epinephrine (also known as adrenaline or adrenalin) is a hormone and a neurotransmitter. Epinephrine has many functions in the body, regulating heart rate, blood vessel and air passage diameters, and metabolic shifts; epinephrine release is a crucial component of the fight-or-flight response of the sympathetic nervous system. Lignocaine is a Local anesthetic which reversely blocks the nerve fibers. It binds to the intracellular portion of sodium channels and blocks sodium influx into nerve cells, which prevents depolarization. Chemically, Lignocaine Hydrochloride is 2-diethylaminoaceto-2,6 -xylidide hydrochloride monohydrate, Epinephrine bitartrate is (R)-1-(3,4-dihydroxyphenyl)-2- methylaminoethanol hydrogen tartrate and Atropine sulphate is (RS)-(1R,3r,5S)-3-tropoyloxytropanium sulphate monohydrate. Literature survey reveals that several HPLC methods are reported for the determination of Atropine sulphate, epinephrine bitartrate, and lignocaine hydrochloride individually. However no method reported for above drugs that stated below in HPLC. The proposed method validated stability indicating method can be used for routine quality control and stability studies of the subjected formulation. MATERIALS AND METHODS Instrumentation The high pressure liquid chromatography (HPLC) system was used of Waters e2695 alliance, auto-sampler with PDA detector supported with Empower Software.
