Stendra is the newest drug on the market, and no generic version is available for sale yet. The 100-mg and 200-mg doses can be taken as shortly as 15 minutes before sexual activity. As a second-generation medication, Stendra also seems to have milder side effects than Viagra and the other PDE5 inhibitors that came before it. Side effects commonly caused by Viagra — but not Stendra — include dizziness, vision changes, nausea, and muscle aches. The only common side effect caused by Stendra but not Viagra is a sore throat. Each drug comes with the risk of drug interactions. Since PDE5 inhibitors work on the body in similar ways, Viagra, Cialis, Levitra, and Stendra lead to similar interactions.

All four of these drugs interact with: nitrates, such as isosorbide mononitrate (Monoket) and nitroglycerin (Nitrostat) certain blood pressure drugs, such as calcium channel blockers alpha blockers, which can treat high blood pressure or an enlarged prostate certain pulmonary hypertension drugs, such as riociguat (Adempas) protease inhibitors, a class of HIV drugs antifungal drugs, such as ketoconazole and itraconazole (Onmel, Sporanox) antibacterial drugs, such as clarithromycin (Biaxin) Drinking excessive amounts of alcohol while on any PDE5 inhibitor should be avoided, and you shouldn’t teva 5343 combine different ED drugs.

Cialis (tadalafil) and Viagra (sildenafil) are phosphodiesterase-5 (PDE5) inhibitors used for treating impotence (erectile dysfunction, or ED).

Common side effects of Cialis and Viagra that are similar include flushing (redness or warmth of the face, neck, or chest), headaches, stomach pain or upset, flu-like symptoms (such as stuffy nose, sneezing, or sore throat), memory problems, muscle or back pain, blurred vision and changes in color vision (such as an inability to differentiate between the colors green and blue), dizziness, diarrhea, nausea, low blood pressure, abnormal ejaculation, and prolonged erections (priapism), loss of hearing, and ringing in the ears. One difference between the drugs is how long they stay in your system.

Cialis provides penile hardness (the ability to obtain an erection) over a longer period than Viagra because it lasts up to 18 hours, while Viagra only lasts for about 4 to 6.

Cialis (tadalafil) and Viagra (sildenafil) are oral drugs that are used for treating impotence (the inability to attain or maintain a penile erection) and benign prostatic hyperplasia (BPH).

They are in a class of drugs called phosphodiesterase-5 (PDE5) inhibitors that also includes vardenafil (Levitra, Staxyn ODT), and avanafil (Stendra).

Penile erection is caused by

the

Under normal conditions, sexual stimulation leads to the production and release of nitric oxide in the penis.

Nitric oxide then activates the enzyme, guanylate cyclase, which causes the production of cyclic guanosine monophosphate (cGMP). It is the cGMP that is primarily responsible for the erection by affecting the amount of blood that the blood vessels deliver and remove from the penis.

Cialis and Viagra inhibit an enzyme called phosphodiesterase-5 (teva 5343 PDE5) which destroys the cGMP. Thus, Cialis and Viagra prevent the destruction of cGMP and allows cGMP to accumulate and persist longer. The longer cGMP persists, the more prolonged the engorgement of the penis. If you are taking Cialis and you have nausea, chest pain or dizziness during sex, seek medical help immediately as you may have a life-threatening condition.

The most common side effects of tadalafil are: facial flushing (reddening), headaches, stomach upset, diarrhea, flu-like symptoms, and nausea. Tadalafil also may cause: low blood pressure, blurred vision, changes in color vision, and abnormal ejaculation. Priapism, or an erection that lasts more than four hours that can damage the penis.

If you are taking Viagra and you have nausea, chest pain or dizziness during sex, seek medical help immediately as you may have a life-threatening condition. Approximately 15% of persons taking Viagra experience side effects.

The most common side effects are: facial flushing (1 in 10), headaches (1 in 6), stomach pain, nasal congestion, nausea, dizziness, rash, urinary tract infections (UTIs) diarrhea, and an inability to differentiate between the colors green and blue.

For most individuals, the recommended starting dose of tadalafil is 10 mg per day taken before sexual activity (tadalafil for use as needed).

Depending on the adequacy of the response or side effects, the dose may be increased to 20 mg or decreased to 5 mg a day. Individuals who are taking medications that increase the blood levels of tadalafil should not exceed a total dose of 10 mg in 72 hours (See drug interactions).

For once daily use without regard to sexual activity, the recommended dose is 2.5 to 5 mg daily.

Tadalafil should not be taken more than once daily.

The recommended dose for BPH, or BPH and ED is 5 mg daily taken about the same time each day. Tadalafil may be taken with or without food since food does not affect its absorption from the intestine.

The dose of tadalafil may require adjustment for patients with reduced kidney or liver function.

The usual recommended dose is 25 to 100 mg 1 hour before sexual activity. The elderly (over 65 years of age) should start at 25 mg before sexual activity. Maximum observed plasma concentrations are reached within 30 to 120 minutes (median 60 minutes) of oral dosing in the fasted state. When sildenafil is taken with a high fat meal, the rate of absorption is reduced, with an average delay in the time to maximal concentration of 1 hour.

The breakdown and elimination of tadalafil from the body may be decreased by erythromycin, ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan) and ritonavir (Norvir).

Therefore, these drugs may increase the levels of tadalafil in the blood.

If these drugs are being used at the same time as tadalafil, the dose of tadalafil should be reduced to 10 mg every 72 hours when used as needed or 2.5 mg when used daily in order to avoid side effects from high levels of tadalafil.

Rifampin, carbamazepine (Tegretol, Tegretol XR, Equerto, Carbatrol), phenytoin (Dilantin, Dilantin-125), and phenobarbital may decrease blood levels of tadalafil, possibly reducing the effect of tadalafil.

Tadalafil exaggerates the increases in heart rate and lowering of blood pressure caused by nitrates, for example, nitroglycerin, isosorbide dinitrate (Isordil), isosorbide mononitrate (Imdur, Ismo, Monoket), nitroglycerin (Nitro-Dur, Transderm-Nitro) that are used primarily for treating heart pain (angina). In patients who take nitrates for angina, tadalafil could cause heart pain or possibly even a heart attack by exaggerating the increase in heart rate and the lowering of blood pressure.

Therefore, tadalafil should not be used with nitrates. Tadalafil also exaggerates the blood pressure lowering effects of some alpha-blocking drugs for example, terazosin (Hytrin) that primarily are used for treating high blood pressure or enlargement of the prostate (BPH). Individuals who take these alpha-blockers should be on a stable dose of the alpha-blocker before tadalafil is started. In such situations, tadalafil should be started at the lowest dose.

If the patient is already taking tadalafil, the alpha-blocker should be started at the lowest dose. Combining tadalafil with alpha-blockers for treatment of BPH is not recommended. Therefore, combining tadalafil with alcohol may cause excessive drops in blood pressure and cause dizziness, headaches, and increased heart rate.

PDE5 inhibitors may affect platelet function and therefore prolong bleeding.

Tadalafil should be used cautiously in patients with bleeding disorders or active ulcers.
