Ketoconazole and Oxandrolone Interaction

Monitor
Mechanism-based 51% confidence

Ketoconazole and Oxandrolone have an interaction requiring monitoring for interaction with 51% confidence. Both Ketoconazole and Oxandrolone carry androgenic activity. Additive androgenic load increases risk of acne, hair loss, and prostate effects. Monitor for dose-dependent side effects. These compounds primarily affect different organ systems.

Compound Profiles

Ketoconazole

Antifungal | Topical Anti-Androgen for Hair Loss

Ketoconazole works through multiple pathways relevant to hair loss. As an azole antifungal, it inhibits the enzyme lanosterol 14-alpha-demethylase, disrupting ergosterol synthesis and killing Malassezia fungi that colonize the scalp and contribute to inflammation and seborrheic dermatitis.

Half-life: Topical application stays local with minimal systemic absorption Typical dose: 1-2% shampoo hair loss

Oxandrolone

Oral Anabolic Steroid | Lean Mass & Recovery

Oxandrolone exerts its anabolic effects primarily through binding to the intracellular androgen receptor (AR), promoting nitrogen retention and protein synthesis in skeletal muscle tissue. As a DHT derivative, it cannot be converted to estrogen by the aromatase enzyme, which means it does not cause estrogen-mediated water retention or gynecomastia.

Half-life: ~9-10 hours Typical dose: 20-50 mg/day (male), 5-20 mg/day (female) anabolic, healing
