Title : Forced Degradation studies of Drospirenone and In Silico Toxicology Predictions for its new Designated Impurities
Abstract:
Aim and Objective: To remain safe for further processing or human consumption, study of stressed degradation for the identification of feasible degradants is required. The stability indicating high performance thin layer chromatographic method was developed by using Camag HPTLC system.
Materials and Methods: Silica C60F254 precoated TLC plates were used as stationary phase for separation of degradation products. The optimized mobile phase system consisted of toluene: methanol: diethylamine (7:3:0.1) at 280 nm.
Results: From the mass details and IR, NMR interpretation, the plausible structure of alkaline degradation product of drospirenone could be 17α (3-hydroxy propyl)-6β, 7β, 15β, 16β-dimethylene-5β-androstane-3β,5,17β triol and acidic degradation product of drospirenone could be 3-oxo-15α,16α-dihydro-3’H-cyclopropa[15,16]-17α-pregna-4,6-diene-21,17-carbolactone.Also In Silico toxicity studies of the degradation products were performed to assess the toxicity profile of the products using Protox online sever.
Conclusion: This analytical method can be considered as an alternative practical and inexpensive method for simple, accurate and efficient quantitative detection of drospirenone in the presence of its degradation products.
