Kialist 20 (Tadalafil 20 mg)

Kialist 20 (Tadalafil 20 mg) is Evolve Biolabs' long-acting PDE5 inhibitor, supplied as 100 tablets in sealed blister strips. It supports erectile function for up to 36 hours after a single dose, which is why it is often called the weekend pill.

What Kialist 20 Is

Tadalafil is a selective phosphodiesterase type 5 inhibitor. PDE5 breaks down cyclic GMP, the second messenger that drives smooth-muscle relaxation and vasodilation. By inhibiting PDE5, tadalafil prolongs cGMP signalling and supports blood flow to erectile tissue. Its distinguishing feature is duration: a half-life of around 17 hours translates into a window of up to 36 hours. Kialist 20 supplies the standard 20 mg strength across 100 tablets.

The History of Cialis

Lilly ICOS brought tadalafil to market in 2003 as Cialis, five years behind sildenafil. The longer duration was the commercial and clinical differentiator, and later approvals added daily low-dose use and benign prostatic hyperplasia. The brand became a household name and helped move erectile dysfunction into routine medical conversation.

How It Works

Tadalafil binds PDE5 and prevents the breakdown of cGMP in vascular smooth muscle. Nitric oxide released during sexual stimulation raises cGMP, and with PDE5 inhibited the signal persists, producing sustained relaxation and increased blood flow. Tadalafil is metabolised mainly in the liver and excreted in bile and urine. Because it is selective for PDE5, it has less effect on other phosphodiesterases than older compounds.

What the Research Shows

• Clinical trials established tadalafil's efficacy and safety for erectile dysfunction.
• Studies show a duration of action of up to 36 hours.
• Daily low-dose regimens have been studied for continuous coverage.
• Tadalafil has also been investigated for pulmonary arterial hypertension and prostate symptoms.

Research Context

Tadalafil's long half-life has made it a subject of research beyond erectile dysfunction. Trials in pulmonary arterial hypertension showed improvements in exercise capacity, and tadalafil was approved for that indication. Daily low-dose regimens have been studied for continuous coverage and for lower urinary tract symptoms associated with benign prostatic hyperplasia. The main safety themes are vasodilation-related effects such as headache and flushing, and the interaction with nitrate drugs, which is absolute and well documented.

Strength, Pack and Authentication

Each tablet contains 20 mg of tadalafil USP, with 100 tablets per pack. The tablets are sealed in moisture-resistant blister strips inside a printed, tamper-evident carton stating the compound, strength and tablet count. A verification code on the packaging links the pack to Evolve Biolabs' records, and the blister format protects each tablet from moisture and light.
