What is Tadagra?

Tadagra is used to treat men who have erectile dysfunction (also called sexual impotence). Tadagra 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, Tadagra 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, Tadagra will not work to cause an erection.

Tadagra 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. Tadagra will make these symptoms less severe and reduce the chance that prostate surgery will be needed. Tadagra is also used to treat erectile dysfunction and signs and symptoms of BPH.

Tadagra 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. Tadagra 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.

Tadagra is available only with your doctor's prescription..

Tadagra description

sponsored

Tadagra is an orally adminstered drug used to treat male erectile dysfunction (impotence). It is marketed worldwide under the brand name Tadagra. It is a phosphodiesterase 5 (PDE5) inhibitor. Tadagra'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 Tadagra nickname of the "weekend pill." This longer half-life also is the basis of current investigation for Tadagra's use in pulmonary arterial hypertension as a once-daily therapy. [Wikipedia]

Potential For Pharmacodynamic Interactions With Tadagra

Nitrates

Administration of Tadagra to patients who are using any form of organic nitrate, is contraindicated. In clinical pharmacology studies, Tadagra was shown to potentiate the hypotensive effect of nitrates. In a patient who has taken Tadagra, where nitrate administration is deemed medically necessary in a life-threatening situation, at least 48 hours should elapse after the last dose of Tadagra before nitrate administration is considered. In such circumstances, nitrates should still only be administered under close medical supervision with appropriate hemodynamic monitoring.

Alpha-Blockers

Caution is advised when PDE5 inhibitors are coadministered with alpha-blockers. PDE5 inhibitors, including Tadagra, 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 Tadagra with doxazosin, tamsulosin or alfuzosin..

Antihypertensives

PDE5 inhibitors, including Tadagra, are mild systemic vasodilators. Clinical pharmacology studies were conducted to assess the effect of Tadagra 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 Tadagra with these agents compared with placebo..

Alcohol

Both alcohol and Tadagra, 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 Tadagra can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache. Tadagra did not affect alcohol plasma concentrations and alcohol did not affect Tadagra plasma concentrations..

Potential For Other Drugs To Affect Tadagra

.

Antacids

Simultaneous administration of an antacid (magnesium hydroxide/aluminum hydroxide) and Tadagra reduced the apparent rate of absorption of Tadagra without altering exposure (AUC) to Tadagra.

H2 Antagonists (e.g. Nizatidine)

An increase in gastric pH resulting from administration of nizatidine had no significant effect on pharmacokinetics.

Cytochrome P450 Inhibitors

Tadagra is a substrate of and predominantly metabolized by CYP3A4. Studies have shown that drugs that inhibit CYP3A4 can increase Tadagra exposure.

CYP3A4 (e.g., Ketoconazole)

Ketoconazole (400 mg daily), a selective and potent inhibitor of CYP3A4, increased Tadagra 20 mg single-dose exposure (AUC) by 312% and Cmax by 22%, relative to the values for Tadagra 20 mg alone. Ketoconazole (200 mg daily) increased Tadagra 10-mg singledose exposure (AUC) by 107% and Cmax by 15%, relative to the values for Tadagra 10 mg alone.

Although specific interactions have not been studied, other CYP3A4 inhibitors, such as erythromycin, itraconazole, and grapefruit juice, would likely increase Tadagra exposure.

HIV Protease inhibitor

Ritonavir (500 mg or 600 mg twice daily at steady state), an inhibitor of CYP3A4, CYP2C9, CYP2C19, and CYP2D6, increased Tadagra 20-mg single-dose exposure (AUC) by 32% with a 30% reduction in Cmax, relative to the values for Tadagra 20 mg alone. Ritonavir (200 mg twice daily), increased Tadagra 20-mg single-dose exposure (AUC) by 124% with no change in Cmax, relative to the values for Tadagra 20 mg alone. Although specific interactions have not been studied, other HIV protease inhibitors would likely increase Tadagra exposure.

Cytochrome P450 Inducers

Studies have shown that drugs that induce CYP3A4 can decrease Tadagra exposure.

CYP3A4 (e.g., Rifampin)

Clinical Trials Experience

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.

Tadagra was administered to over 9000 men during clinical trials worldwide. In trials of Tadagra 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 Tadagra for use as needed, over 1300 and 1000 subjects were treated for at least 6 months and 1 year, respectively.

Tadagra For Use As Needed For ED

Additional, less frequent adverse reactions ( < 1%) reported in the controlled clinical trials of Tadagra 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 Tadagra 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 Tadagra 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 Tadagra 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 Tadagra for once daily use for ED, BPH and BPH/ED are described in Tables 2, 3 and 4. In studies of Tadagra 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 Tadagra for use as needed for ED, diarrhea was reported more frequently in patients 65 years of age and older who were treated with Tadagra (2.5% of patients).

Across all studies with any Tadagra 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 Tadagra for once daily use or use as needed. A causal relationship of these events to Tadagra 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

What is the most important information I should know about Tadagra?

Do not take Tadagra if you are allergic to it, or if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin (Nitro Dur, Nitrolingual, Nitrostat, Transderm Nitro, and others), isosorbide dinitrate (Dilatrate, Isordil, Isochron), isosorbide mononitrate (Imdur, ISMO, Monoket), or recreational drugs such as amyl nitrate or nitrite ("poppers"). Taking Tadagra with a nitrate medicine can cause a sudden and serious decrease in blood pressure.

If you become dizzy or nauseated during sexual activity, or if you have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away. You could be having a serious side effect of Tadagra.

Do not take Tadagra more than once a day. Allow 24 hours to pass between doses.

Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.

Tadagra can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking Tadagra, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old. It is not clear whether Tadagra is the actual cause of vision loss.

Stop using Tadagra and get emergency medical help if you have sudden vision loss.
