What is the most important information I should know about Talis?
5 mg Film-coated Tablet: Hypersensitivity to the active substance or to any of the excipients.
In clinical studies, Talis was shown to augment the hypotensive effects of nitrates. This is thought to result from the combined effects of nitrates and Talis on the nitric oxide/cGMP pathway. Therefore, administration of Talis to patients who are using any form of organic nitrate is contraindicated..
Talis, must not be used in men with cardiac disease for whom sexual activity is inadvisable. Physicians should consider the potential cardiac risk of sexual activity in patients with pre-existing cardiovascular disease.
20 mg Film-coated Tablet: Nitrates and Talis must not be used concomitantly. Co-administration of Talis with nitric oxide donors, organic nitrates or organic nitrites in any form either regularly or intermittently is contraindicated. Drugs which must not be used concomitantly include, but are not limited to, glyceryl trinitrate (injection, tablets, sprays or patches), isosorbide salts, sodium nitroprusside, amyl nitrite, nicorandil or organic nitrates in any form. In clinical studies, Talis was shown to potentiate the hypotensive effects of both acute and chronic nitrate administration. This is thought to result from the combined effects of nitrates and Talis on the nitric oxide/cGMP pathway.
Based on the results of a clinical study in which 150 subjects receiving daily doses of Talis 20 mg for 7 days and 0.4 mg sublingual nitroglycerin at various times, this interaction lasted for more than 24 hours and was no longer detectable when 48 hours had elapsed after the last Talis dose. Thus, in a patient prescribed Talis, where nitrate administration is deemed medically necessary in a life-threatening situation, at least 48 hours should have elapsed after the last dose of Talis before nitrate administration is considered. In such circumstances, nitrates should only be administered under close medical supervision with appropriate haemodynamic monitoring.
5 mg and 20 mg Film-coated Tablet: The following groups of patients with cardiovascular disease were not included in clinical trials and the use of Talis is therefore contraindicated: Patients with myocardial infarction within the last 90 days; patients with unstable angina or angina occurring during sexual intercourse; patients with New York Heart Association Class 2 or greater heart failure in the last 6 months; patients with uncontrolled arrhythmias, hypotension (<90/50 mm Hg), or uncontrolled hypertension; patients with a stroke within the last 6 months.
Talis is contraindicated in patients who have loss of vision in one eye because of non-arteritic anterior ischaemic optic neuropathy (NAION), regardless of whether this episode was in connection or not with previous PDE5 inhibitor exposure.
Talis should not be used in patients with a known hypersensitivity to Talis or to any ingredient of the tablet.

What are the possible side effects of Talis?
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Talis was administered to over 9000 men during clinical trials worldwide. In trials of Talis for once daily use, a total of 1434, 905, and 115 were treated for at least 6 months, 1 year, and 2 years, respectively. For Talis for use as needed, over 1300 and 1000 subjects were treated for at least 6 months and 1 year, respectively.
Talis For Use As Needed For EDIn eight primary placebo-controlled clinical studies of 12 weeks duration, mean age was 59 years (range 22 to 88) and the discontinuation rate due to adverse events in patients treated with Talis 10 or 20 mg was 3.1%, compared to 1.4% in placebo treated patients.
When taken as recommended in the placebo-controlled clinical trials, the following adverse reactions were reported for Talis for use as needed:

Additional, less frequent adverse reactions ( < 1%) reported in the controlled clinical trials of Talis for BPH or ED and BPH included: gastroesophageal reflux disease, upper abdominal pain, nausea, vomiting, arthralgia, and muscle spasm.
Back pain or myalgia was reported at incidence rates described in Tables 1 through 4. In Talis clinical pharmacology trials, back pain or myalgia generally occurred 12 to 24 hours after dosing and typically resolved within 48 hours. The back pain/myalgia associated with Talis treatment was characterized by diffuse bilateral lower lumbar, gluteal, thigh, or thoracolumbar muscular discomfort and was exacerbated by recumbency. In general, pain was reported as mild or moderate in severity and resolved without medical treatment, but severe back pain was reported with a low frequency ( < 5% of all reports). When medical treatment was necessary, acetaminophen or non-steroidal anti-inflammatory drugs were generally effective; however, in a small percentage of subjects who required treatment, a mild narcotic (e.g., codeine) was used. Overall, approximately 0.5% of all subjects treated with Talis for on demand use discontinued treatment as a consequence of back pain/myalgia. In the 1-year open label extension study, back pain and myalgia were reported in 5.5% and 1.3% of patients, respectively. Diagnostic testing, including measures for inflammation, muscle injury, or renal damage revealed no evidence of medically significant underlying pathology. Incidence rates for Talis for once daily use for ED, BPH and BPH/ED are described in Tables 2, 3 and 4. In studies of Talis for once daily use, adverse reactions of back pain and myalgia were generally mild or moderate with a discontinuation rate of < 1% across all indications.
Across placebo-controlled studies with Talis for use as needed for ED, diarrhea was reported more frequently in patients 65 years of age and older who were treated with Talis (2.5% of patients).
Across all studies with any Talis dose, reports of changes in color vision were rare ( < 0.1% of patients).
The following section identifies additional, less frequent events ( < 2%) reported in controlled clinical trials of Talis for once daily use or use as needed. A causal relationship of these events to Talis is uncertain. Excluded from this list are those events that were minor, those with no plausible relation to drug use, and reports too imprecise to be meaningful:
Body as a Whole - asthenia, face edema, fatigue, pain, peripheral edema
Cardiovascular - angina pectoris, chest pain, hypotension, myocardial infarction, postural hypotension, palpitations, syncope, tachycardia
Digestive - abnormal liver function tests, dry mouth, dysphagia, esophagitis, gastritis, GGTP increased, loose stools, nausea, upper abdominal pain, vomiting, gastroesophageal reflux disease, hemorrhoidal hemorrhage, rectal hemorrhage
Musculoskeletal - arthralgia, neck pain
Nervous - dizziness, hypesthesia, insomnia, paresthesia, somnolence, vertigo Renal and Urinary
Talis tablets are indicated for the treatment of erectile dysfunction (ED).
Benign Prostatic Hyperplasia
Talis tablets are indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia (BPH).
Erectile Dysfunction and Benign Prostatic Hyperplasia
Talis tablets are indicated for the treatment of ED and the signs and symptoms of BPH (ED/BPH).
Limitation of Use
If Talis tablets are used with finasteride to initiate BPH treatment, such use is recommended for up to 26 weeks because the incremental benefit of Talis tablets decrease from 4 weeks until 26 weeks, and the incremental benefit of Talis tablets beyond 26 weeks is unknown.
Talis is used to treat men who have erectile dysfunction (also called sexual impotence). Talis belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly. The penis is one of the areas where this enzyme works.
Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. When a man is sexually stimulated, his body's normal response is to increase blood flow to his penis to produce an erection. By controlling the enzyme, Talis helps to maintain an erection after the penis is stroked by increasing blood flow to the penis. Without physical action to the penis, such as that occurring during sexual intercourse, Talis will not work to cause an erection.
Talis is also used to treat men who have signs and symptoms of benign prostatic hyperplasia (BPH). BPH is caused by an enlarged prostate. Men with BPH usually have difficulty urinating, a decreased flow of urination, hesitation at the beginning of urination, and a need to get up at night to urinate. Talis will make these symptoms less severe and reduce the chance that prostate surgery will be needed. Talis is also used to treat erectile dysfunction and signs and symptoms of BPH.
Talis is also used in both men and women to treat the symptoms of pulmonary arterial hypertension. This is high blood pressure that occurs in the main artery that carries blood from the right side of the heart (the ventricle) to the lungs. When the smaller blood vessels in the lungs become more resistant to blood flow, the right ventricle must work harder to pump enough blood through the lungs. Talis works on the PDE5 enzyme in the lungs to relax the blood vessels. This will increase the supply of blood to the lungs and reduce the workload of the heart.
Talis is available only with your doctor's prescription..
Talis is an orally adminstered drug used to treat male erectile dysfunction (impotence). It is marketed worldwide under the brand name Talis. It is a phosphodiesterase 5 (PDE5) inhibitor. Talis'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 Talis nickname of the "weekend pill." This longer half-life also is the basis of current investigation for Talis's use in pulmonary arterial hypertension as a once-daily therapy. [Wikipedia]
Use Talis as directed by your doctor. Check the label on the medicine for exact dosing instructions.
Ask your health care provider any questions you may have about how to use Talis.
There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.Talis is used to treat high blood pressure in the lungs (pulmonary hypertension). It works by relaxing and widening the blood vessels in your lungs which allows the blood to flow more easily. Decreasing high blood pressure in the lungs allows your heart and lungs to work better and improves your ability to exercise.

What other drugs will affect Talis?
Administration of Talis to patients who are using any form of organic nitrate, is contraindicated. In clinical pharmacology studies, Talis was shown to potentiate the hypotensive effect of nitrates. In a patient who has taken Talis, where nitrate administration is deemed medically necessary in a life-threatening situation, at least 48 hours should elapse after the last dose of Talis before nitrate administration is considered. In such circumstances, nitrates should still only be administered under close medical supervision with appropriate hemodynamic monitoring.
Alpha-BlockersCaution is advised when PDE5 inhibitors are coadministered with alpha-blockers. PDE5 inhibitors, including Talis, and alpha-adrenergic blocking agents are both vasodilators with blood-pressure-lowering effects. When vasodilators are used in combination, an additive effect on blood pressure may be anticipated. Clinical pharmacology studies have been conducted with coadministration of Talis with doxazosin, tamsulosin or alfuzosin..
AntihypertensivesPDE5 inhibitors, including Talis, are mild systemic vasodilators. Clinical pharmacology studies were conducted to assess the effect of Talis on the potentiation of the bloodpressure- lowering effects of selected antihypertensive medications (amlodipine, angiotensin II receptor blockers, bendrofluazide, enalapril, and metoprolol). Small reductions in blood pressure occurred following coadministration of Talis with these agents compared with placebo..
AlcoholBoth alcohol and Talis, a PDE5 inhibitor, act as mild vasodilators. When mild vasodilators are taken in combination, blood-pressure-lowering effects of each individual compound may be increased. Substantial consumption of alcohol (e.g., 5 units or greater) in combination with Talis can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache. Talis did not affect alcohol plasma concentrations and alcohol did not affect Talis plasma concentrations..
Potential For Other Drugs To Affect Talis.
AntacidsSimultaneous administration of an antacid (magnesium hydroxide/aluminum hydroxide) and Talis reduced the apparent rate of absorption of Talis without altering exposure (AUC) to Talis.
H2 Antagonists (e.g. Nizatidine)An increase in gastric pH resulting from administration of nizatidine had no significant effect on pharmacokinetics.
Cytochrome P450 InhibitorsTalis is a substrate of and predominantly metabolized by CYP3A4. Studies have shown that drugs that inhibit CYP3A4 can increase Talis exposure.
CYP3A4 (e.g., Ketoconazole)
Ketoconazole (400 mg daily), a selective and potent inhibitor of CYP3A4, increased Talis 20 mg single-dose exposure (AUC) by 312% and Cmax by 22%, relative to the values for Talis 20 mg alone. Ketoconazole (200 mg daily) increased Talis 10-mg singledose exposure (AUC) by 107% and Cmax by 15%, relative to the values for Talis 10 mg alone.
Although specific interactions have not been studied, other CYP3A4 inhibitors, such as erythromycin, itraconazole, and grapefruit juice, would likely increase Talis exposure.
HIV Protease inhibitorRitonavir (500 mg or 600 mg twice daily at steady state), an inhibitor of CYP3A4, CYP2C9, CYP2C19, and CYP2D6, increased Talis 20-mg single-dose exposure (AUC) by 32% with a 30% reduction in Cmax, relative to the values for Talis 20 mg alone. Ritonavir (200 mg twice daily), increased Talis 20-mg single-dose exposure (AUC) by 124% with no change in Cmax, relative to the values for Talis 20 mg alone. Although specific interactions have not been studied, other HIV protease inhibitors would likely increase Talis exposure.
Cytochrome P450 InducersStudies have shown that drugs that induce CYP3A4 can decrease Talis exposure.
CYP3A4 (e.g., Rifampin)
