Product Overview

Tadalafil Description1-3

Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor with a mean terminal half-life exceeding 17 hours, which is longer than that of other PDE5 inhibitors. This extended half-life supports either once-daily or on-demand dosing. Tadalafil is indicated for the treatment of pulmonary arterial hypertension (PAH), erectile dysfunction (ED), benign prostatic hypertrophy (BPH), or the combined management of ED and BPH.

Citrulline Description4

Citrulline, commonly associated with watermelon, is an amino acid that is converted in the body to argininosuccinate and subsequently to arginine. The kidneys further convert citrulline into arginine and nitric oxide. Nitric oxide is involved in several physiological processes, including vasodilation of blood vessels, immune function support, and regulation of glucose and fatty acid metabolism. Because of its conversion to nitric oxide, citrulline has been studied in relation to erectile dysfunction.

Vitamin B65

Vitamin B6 is a water-soluble vitamin that plays a role in neurotransmitter function, brain health, immune system activity, and metabolic processes in the body.

Vitamin B126

Cyanocobalamin, the synthetic form of vitamin B12, supports various methylation reactions in the body. It is required for growth, cell replication, hematopoiesis, and the synthesis of nucleoproteins and myelin. It also contributes to red blood cell production and the function of rapidly dividing cells, including epithelial, bone marrow, and myeloid cells.

Zinc7

Zinc is an essential trace element involved in numerous biological processes, including appetite regulation, testicular maturation, immune function, and wound healing.

Tadalafil1-3

Phosphodiesterase (PDE) has many isoforms and is an enzyme that has many functions in the body including degrading the effect of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). PDE5 is an enzyme that is found in many parts of the body including in the smooth muscle of the corpus cavernosum, prostate, bladder, the vascular and visceral smooth muscle, skeletal muscle, urethra, platelets, kidney, lung, cerebellum, heart, liver, testis, seminal vesicle, and pancreas. Tadalafil is a selective inhibitor of PDE5, the enzyme responsible for the degradation of cGMP. The drug has selective activity on PDE5 than other phosphodiesterase isoforms. Tadalafil activity on PDE5 is more than 10,000-fold more than for PDE1, PDE2, PDE4, and PDE7 enzymes. Increased cGMP leads to smooth muscle relaxation in the corpus cavernosum which can help in maintaining a penile erection.

Citrulline4

Citrulline may inhibit the activity of PDE5 in the body by increasing arginine availability, stimulating production of nitric oxide and preventing degradation of cGMP. This activity may increase the ability to gain and maintain a penile erection through muscle relaxation.

Vitamin B65

Vitamin B6 is made up of at least three main compounds: pyridoxine, pyridoxal, and pyridoxamine. Pyridoxine works in the red blood cells to be activated. Pyridoxamine acts as a coenzyme while pyridoxamine is converted into pyridoxamine phosphate. These active forms act as coenzymes for at least 60 metabolic processes including the metabolism of fat, protein, and carbohydrate.

Vitamin B126

Vitamin B12 is important for division and growth of the cell. It is converted to coenzyme B12 in the body and in this form facilitates the conversion of homocysteine to methionine (methylcobalamin) and plays an important role in converting methylmalonyl-coenzyme A to succinyl-Co-A (fatty acid and amino acid metabolism). Without coenzyme B12, tetrahydrofolate cannot be produced from 5-methyl tetrahydrofolate leading to folate deficiency. In addition, vitamin B12 is needed to produce myelin and is important for axon and nerve development. Gastrointestinal absorption of vitamin B12 depends on the presence of sufficient intrinsic factor and calcium ions.

Zinc7

Zinc is important for enzymatic activity in the body involving carbohydrates, lipids, proteins, and nucleic acids. It may provide support for immune function, wound healing and development of testicular activity.
