Latest research on Cialis

Tadalafil is an orally adminstered drug used to treat male erectile dysfunction (impotence). It is marketed worldwide under the brand name Cialis. It is a phosphodiesterase 5 (PDE5) inhibitor. Tadalafil's distinguishing pharmacologic feature is its longer half-life (17.5 hours) compared with Viagra and Levitra (4-5 hours). This longer half-life results in a longer duration of action and is, in part, responsible for the Cialis nickname of the "weekend pill." This longer half-life also is the basis of current investigation for tadalafil's use in pulmonary arterial hypertension as a once-daily therapy. [Wikipedia]

Latest findings

As such, in the second step, the Japanese keywords personal import agent (‘個人輸入代行’) and Cialis (‘シアリス’), ‘50 mg’ and ‘100 mg’, were used, and first 100 results were further screened out from a list of more than 35 000. [source, 2012]
The physical characteristics (eg, colour of genuine and counterfeits, strength, packaging) of original and counterfeit Cialis and Levitra were identified earlier by the Ministry of Health, Japan. [source, 2012]
11. Cialis (text word) [source, 2012]
We focussed on outcomes that we could investigate within the GPRD by identifying incident events through Read or OXMIS codes for the clinical diagnosis, with the exception of osteoporosis – for which patients prescribed a bisphosphonate were included even if they did not have a clinical code for osteoporosis or osteoporotic fracture – and erectile dysfunction – for which we included new prescriptions for sildenafil (Viagra, Pfizer, NY, United States), apomorphone hydrochloride, vardenafil (Levitra, Bayer Healthcare Pharmaceuticals, New Haven, USA), Alprostadil (an injectable treatment) and tadalafil (Cialis, Lilly, USA).

In addition, Nitric oxide and PDE-5 inhibitors (Sildenafil and Tadanafil) have been tested, but further research is needed to clarify their role. [source, 2010]
In addition, steroids (Dexamethasone), PDE-5 inhibitors (Sildenafil and Tadanafil) may also be used. [source, 2010]
The US National Association of State Boards of Pharmacy (NABP) ordered several different medications, including Cialis from 13 suspicious websites selling prescription-only medication without a prescription (23). [source, 2010]
The search terms used on PubMed included tadalafil, ED, daily dosing, routine dosing, and Cialis. [source, 2010]
Since normal erection needs a high level concentration of cyclic GMP to decrease calcium ions in vascular smooth muscle cells of the penis, thus, the inhibitors of PDE5 were used for treating erectile dysfunction such as sildenafil citrate (Viagra) and tadalafil (Cialis) [source, 2009]
In this study, sildenafil citrate (Viagra) and tadalafil (Cialis) were selected as the control set in this protocol (Figure 1) [source, 2009]
