Stanazolol is a steroidal class drug. Stanazolol is a synthetic anabolic steroid with therapeutic uses in treating c1-inhibitor deficient hereditary Angioedema. Our main objective is to Development and Validation of Simple UV-Spectroscopic Method for stanazolol in bulk and Pharmaceutical dosage Form and development and Validation of RP-HPLC methods for estimation of Stanazolol in Bulk and Pharmaceutical dosage Form. Comparison of Developed and Validated RP-HPLC Method against the developed and Validated Simple Uv-Spectrophotometric Method. development of force degradation method for detection of possible impurity of Stanazolol in API and pharmaceutical dosage form.
