Tadalafil vs TriMix
A side-by-side research comparison of Tadalafil and TriMix across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Tadalafil | TriMix |
|---|---|---|
| Full name | Tadalafil (Cialis) | TriMix (Papaverine + Phentolamine + Alprostadil) |
| Category | Sexual Health | Sexual Health |
| Status | FDA-approved prescription | Compounded medication |
| Mechanism | Selectively inhibits phosphodiesterase type 5 (PDE5), preventing cGMP breakdown in smooth muscle. This enhances nitric oxide signaling for vasodilation in penile, pulmonary, and prostate tissue. | Papaverine relaxes smooth muscle via PDE inhibition. Phentolamine blocks alpha-adrenergic receptors. Alprostadil (PGE1) directly stimulates cAMP production in cavernosal tissue. Together they produce reliable penile erection independent of arousal. |
| Molecular weight | 389.40 Da | Combination compound |
| Half-life | ~17.5 hours | ~1-3 hours (local effect) |
| Bioavailability | ~36% oral | Direct intracavernosal: ~100% |
| Typical dose | 2.5-5 mg daily or 10-20 mg as needed | 0.1-0.5 mL (titrated) |
| Frequency | Daily or on-demand | As needed, max 3x/week |
| Route | Oral tablet | Intracavernosal injection |
