SOLID FORMS OF EMTRICITABINE

摘要

The present invention provides novel crystalline forms of Emtricitabine, designated Emtricitabine form ULT-I, form ULT-2 and ULT-3, methods for the preparation of Emtricitabine form ULT-I, ULT-2 and ULT-3 and the use of Emtricitabine form ULT-I and/or ULT-2 and/or ULT-3 in pharmaceutical applications, in particular in anti-HIV medicaments. The crystalline form of Emtricitabine form ULT-I, ULT-2 and/or ULT-3 can be used in combination with other anti-HIV medicaments such as Efavirenz and Tenofovir DF.
