This study is designed to explore the bioequivalence of Test Product Vaptor (Rosuvastatin) 20 mg Tablet with the reference product Crestor (Rosuvastatin) 20 mg tablet under fasting conditions in healthy Pakistani male subjects.

This is a single-center, open-label, randomized, single-dose, two-period, two-way, cross-over study. Subjects will receive one single dose per treatment period of Test and Reference Drugs separated by a wash-out period of 7 days. Blood samples will be taken up to 72 hours post-dose. The primary pharmacokinetic parameters will be compared for both drugs to assess the bioequivalence.

Inclusion Criteria:

• Healthy male volunteers aged 18 to 55 years inclusive.
• Subjects with a body mass index from 18.5 to 30 kg/m2 (both inclusive).
• Subjects who are healthy as determined by routine physical examination, including vital sign monitoring (ie, blood pressure, heart rate, and temperature), 12 Lead ECG, and laboratory analysis (ie, hematology, blood biochemistry, and urinalysis)and viral serology as determined by the investigator.
• Subjects should have a negative urine test for drugs of abuse (MOP (morphine) and THC (tetrahydrocannabinol) will be tested) and alcohol breath analysis at screening and prior to each check-in.
• Subjects will be able to, understand and sign the Informed Consent Form for Medical Screening during their screening visit and Participation Informed Consent Form on study check-In day.

Exclusion Criteria:
