Cialis 25 – Product Overview
Cialis 25 provides research-grade Tadalafil Citrate in a 50-tablet bottle, delivering 25mg per tablet. Tadalafil is a well-known PDE5 inhibitor studied for its extended duration of action and its role in supporting vasodilation and hemodynamic response in erectile-function research models.
Scientific Background
Tadalafil functions through selective inhibition of phosphodiesterase type-5 (PDE5), an enzyme responsible for degrading cyclic guanosine monophosphate (cGMP). When PDE5 is inhibited, cGMP activity persists longer, supporting improved smooth-muscle relaxation and facilitating enhanced blood-flow dynamics in tissues regulated by nitric oxide.
Key Research-Based Characteristics
- Long-Acting PDE5 Inhibition: Known for a significantly longer half-life than most PDE5 inhibitors, enabling prolonged physiological effects.
- Smooth-Muscle Relaxation: Commonly examined in studies involving penile hemodynamics and erectile physiology.
- Vascular Research Applications: Supports investigations into endothelial function, nitric-oxide signaling, and circulatory performance.
- Non-Hormonal Mechanism: Acts enzymatically at the PDE5 receptor pathway rather than influencing endocrine markers.
- Consistent Pharmacokinetics: Offers predictable absorption and sustained systemic activity, beneficial for controlled research settings.
Product Composition
- Quantity: 50 tablets
- Strength: 25mg Tadalafil Citrate per tablet
- Compound Type: PDE5 inhibitor
- Form: Oral tablet
Research Applications
- Vasodilation and smooth-muscle response studies
