Review and Description

Direktan is the brand name of Sildenafil citrate, manufactured by Gerot Lannach Pharma GmBH in Austria. The drug is mainly used to treat men with erectile dysfunction, though, it may also be used to treat men and women with pulmonary arterial hypertension. Sildenafil citrate belongs to the class of Phosphodiesterase-5 inhibitors (PDEIs). PDE-5 is an enzyme that breaks down cGMP, thereby promoting smooth muscle contraction. The inhibition of the PDE-5 will result in the increase of cGMP, promoting vasodilation, resulting in a decrease in blood pressure. Simultaneously, it relaxes the blood vessel of the penis, the corpus cavernosum, which allows it to take in more blood. The mechanism of action of the drug maintains the erection as it lowers the blood pressure. It should be noted that the drug only works when there is stimulation of the penis. Gerot Lannach Pharma GmBH is a drug manufacturing company located in Austria, with the production and packaging of solid dosage forms in Lannach/Graz and the production and packaging of semi-solid and liquid dosage forms in Vienna.
