• Grapefruit or grapefruit juice or products containing grapefruit juice

9. Willingness to abstain from ingesting Seville oranges, garlic supplements, St. John's Wort, or Milk Thistle, within 5 days of treatment and for the duration of the study

10. Willingness to abstain from methylxanthine-containing drinks or foods (coffee, tea, cola, energy drinks, chocolate, etc.) within 72 hours of each pharmacokinetic (PK) sampling day and until after the last sample from each of the intensive sampling days is collected

11. Willingness to abstain from over the counter herbal medications for the duration of the study

12. Willingness to abstain from vigorous physical exercise during PK Days

13. Reasonable probability for completion of the study

Exclusion Criteria

1. Female subjects who are of reproductive potential who:

• Have positive serum β-human chorionic gonadotropin at Visit 1, or on Day 0
• Have not been using a barrier contraceptive method for at least 3 months prior to Day 0 (Visit 2)
• Are not willing to use a reliable method of barrier contraception (such as diaphragm or condoms), during the trial and 30 days after completion/termination
• Are breast-feeding

2. Use of any pharmacological contraceptive (including oral, patch or injectable contraceptives) for 1 month prior to study initiation and for the duration of the study

3. Use of hormone replacement therapy for 1 month prior to study initiation and for the duration of the study

4. Participation in another trial with an investigational medicine within 60 days prior to Day 0 (Visit 2)

5. Use of any medication listed in the protocol within 30 days prior to Day 0 (Visit 2)

6. Administration of antibiotics within 10 days prior to Day 0 (Visit 2) or during the trial

7. History of acute illness within the past sixty (60) days. Subjects will be excluded for these disorders greater than sixty days if, in the opinion of the investigator, the subject does not qualify as a healthy volunteer

8. Have serological evidence of Hepatitis B or C Virus

9. Have serological evidence of exposure to HIV

10. Recent history of alcohol or substance abuse (within 6 months of study period)

11. Smokers who smoke greater than 10 cigarettes or 3 cigars or 3 pipes per day; inability to refrain from smoking during the trial

13. Subjects with a seated systolic blood pressure either <100 mm Hg or >150 mm Hg; resting heart rate either <50 beats/min or >90 beats/min

14. Subjects with a history of any illness or allergy that, in the opinion of the investigator,might confound the results of the study or pose additional risk in administering Tipranavir,Ritonavir, atorvastatin or erythromycin to the subject

15. Subjects who are currently taking any over-the-counter drug within 7 days prior to Day 0,(Visit 2) or who are currently taking any prescription drug that, in the opinion of the investigator in consultation with the clinical monitor, might interfere with either the absorption, distribution or metabolism of the test substances
