Description
Tadalafil Product Overview
Tadalafil (C22H19N3O4) is a white crystalline powder that is practically insoluble in water. It is the (6R,12aR)-diastereomer, so stereochemical purity is a key specification. Its very low solubility makes particle size control important for dissolution.
Pharmaceutical companies use it in film-coated tablets for erectile dysfunction, benign prostatic hyperplasia and pulmonary arterial hypertension, with different strengths for each indication. Compared with Sildenafil Citrate, it has a much longer half-life.
Like sildenafil, it is often found illegally in products sold as herbal or ‘natural’ remedies. Zyntex therefore supplies it only to licensed pharmaceutical companies with documented end use and does not sell it for food or herbal products.
