What is the L339 pill?
The L339 pill is a yellow, oval tablet containing Tadalafil, according to pill identifier databases. Tadalafil is also known by the brand names Cialis (for ED/BPH) and Adcirca (for PAH). It is a prescription-only medication classified as a phosphodiesterase-5 (PDE5) inhibitor. Always confirm pill identification with a healthcare provider.
The primary uses of the L339 pill
The active ingredient in the L339 pill, Tadalafil, treats conditions by improving blood flow or relaxing smooth muscles in specific body parts.
Tadalafil for Erectile Dysfunction (ED)
Tadalafil helps men with ED achieve and maintain an erection during sexual stimulation by increasing blood flow to the penis. It works by inhibiting the PDE5 enzyme. A key feature of Tadalafil is its duration of action, which can be extended compared to some other medications in its class.
Tadalafil for Benign Prostatic Hyperplasia (BPH)
For men with an enlarged prostate, Tadalafil can alleviate symptoms like difficulty starting urination, a weak stream, and frequent or urgent urination, especially at night. It does this by relaxing smooth muscles in the prostate and bladder, improving urinary flow.
Tadalafil for Pulmonary Arterial Hypertension (PAH)
Under the brand name Adcirca, Tadalafil treats high blood pressure in the arteries leading to the lungs. It relaxes these blood vessels, lowering pressure, reducing heart strain, and improving exercise capacity.
How does the L339 pill work?
Tadalafil, a PDE5 inhibitor, works by blocking the PDE5 enzyme, which leads to increased levels of cGMP in smooth muscle cells. This causes blood vessels to relax and widen, increasing blood flow. This improved blood flow helps with erections during sexual stimulation, relaxes pulmonary blood vessels for PAH, and relaxes bladder and prostate smooth muscle for BPH.
Tadalafil (L339) Administration
Tadalafil is taken orally as a tablet. It can be taken with or without food, but tablets should be swallowed whole. The specific administration schedule and amount depend on the condition being treated.
Potential side effects of Tadalafil (L339)
