    Tadalafil formula


    Cialis (or Tadalafil) was developed by American pharmaceutical company Lilly. It is used to treat erectile dysfunction and belongs to a second generation of PDE5 inhibitors. Studies show that Cialis works very quickly, taking effect in around 15-20 minutes, and has a prolonged effect that can last for up to 36 hours. In a study of 348 cases of mild to severe erectile dysfunction, patients were randomly given 20mg of Cialis or a placebo. Results showed that in comparison to the placebo group, patients who took Cialis experienced improved intercourse success in the 24-36 hours following medication, with many patients achieving successful sexual intercourse twice in 36 hours. Side effect rate and severity were also no different from those of the placebo group. Over 5% of patients in the Cialis group experienced headaches and indigestion. No perceived facial flushing or sight abnormalities following medication. Patients currently taking nitrates, experiencing angina pectoris, suffering from heart disease, patients who have unregulated hypertension or hypotension, or patients who have had a stroke in the past 6 months should not take Cialis. Tadalafil (market name “Cialis” or “Adcirca”) is a kind of PDE5 inhibitor used for the treatment of erectile dysfunction, benign prostatic hypertrophy and pulmonary arterial hypertension. levofloxacin spc We use cookies and similar technologies to improve your browsing experience, personalize content and offers, show targeted ads, analyze traffic, and better understand you.

The strongest link was for depressed patients prescribed Effexor (venlafaxine) or antidepressants called serotonin reuptake inhibitors (SSRIs), the British study found. SSRIs include citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac), paroxetine (Paxil) and sertraline (Zoloft). However, many patients who developed mania or bipolar symptoms likely had underlying bipolar disorder or a predisposition because of family history or other factors, the researchers believe. Also, the study was observational, and "we did not demonstrate a causal association between antidepressants and mania and bipolar disorder," said lead researcher Dr. Rashmi Patel, of the department of psychosis studies at King's College London's Institute of Psychiatry, Psychology and Neuroscience.
