Ketoconazole and LGD-4033 Interaction

Monitor
Mechanism-based 51% confidence

Ketoconazole and LGD-4033 have an interaction requiring monitoring for interaction with 51% confidence. Both Ketoconazole and LGD-4033 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

LGD-4033

Selective Androgen Receptor Modulator | Lean Mass

LGD-4033 binds to the androgen receptor with high affinity (Ki of approximately 1 nM), functioning as a potent and selective agonist in muscle and bone tissue. Like other SARMs, its tissue selectivity is mediated by differential cofactor recruitment: upon binding to the AR, LGD-4033 induces a receptor conformation that preferentially recruits coactivators expressed in skeletal muscle and bone, while showing minimal agonist activity in androgen-sensitive tissues such as the prostate and skin.
