Dutasteride and MK-2866 Interaction

Avoid
Mechanism-based 64% confidence

Dutasteride and MK-2866 have a potentially harmful interaction with 64% confidence. Both Dutasteride and MK-2866 carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. These compounds primarily affect different organ systems.

Compound Profiles

Dutasteride

Dual 5-Alpha Reductase Inhibitor | Hair Loss & BPH

Dutasteride competitively inhibits both the Type I and Type II isoforms of the enzyme 5-alpha reductase. Type II is the predominant isoform in the prostate and hair follicles, while Type I is found primarily in the skin, sebaceous glands, and liver.

Half-life: ~5 weeks (extremely long; active metabolite accumulation over months) Typical dose: 0.5mg/day hair loss

MK-2866

Selective Androgen Receptor Modulator | Muscle Wasting Research

MK-2866 binds to the androgen receptor (AR) with high affinity and selectivity, functioning as a partial agonist in muscle and bone tissue. Upon binding, the MK-2866-AR complex undergoes a conformational change that promotes nuclear translocation and interaction with androgen response elements (AREs) on DNA, activating transcription of genes involved in protein synthesis, nitrogen retention, and myogenic differentiation.

Frequently Asked Questions

Can I take Dutasteride with MK-2866?

Combining Dutasteride with MK-2866 is not recommended. Both Dutasteride and MK-2866 carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently.

Is Dutasteride and MK-2866 safe together?

This combination carries significant risk. Both Dutasteride and MK-2866 carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. Consult a healthcare professional before combining.

What are the interactions between Dutasteride and MK-2866?

Both Dutasteride and MK-2866 carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. This assessment has 64% confidence and is inferred from pharmacological mechanism analysis.

How should I time Dutasteride and MK-2866?

Dutasteride has a half-life of ~5 weeks (extremely long; active metabolite accumulation over months) and MK-2866 has a half-life of ~24 hours. No specific timing requirements identified for this combination, but separating administration can help monitor individual effects.
