Cialis (Yellow Tablets)

Common use
Cialis is an effective, reversible, selective inhibitor of phosphodiesterase type 5 (PDE 5) specific to cyclic guanosine monophosphate (cGMP). When sexual stimulation causes local release of nitric oxide, inhibition of PDE 5 by Cialis leads to increase of cGMP levels in the cavernous body of penis. It results in relaxation of arterial smooth muscles and blood flow to the tissues of the penis that causes erections. Cialis has no effect when sexual stimulation is absent. Cialis improves erection and lets achieve a successful sexual intercourse. The drug acts during 36 hours. If sexual arousal is present the effect appears even after 16 minutes after the medication was taken.

Dosage and direction
The recommended dose of Cialis is 20 mg it should be taken at least 16 minutes before the sexual activity. The effect persists during 36 hours. Take Cialis once daily and do not exceed the recommended dose.

Precautions
It is preferable not to use Cialis with grapefruit juice, alcoholic beverages, tobacco. If you smoke tobacco and take Cialis concomitantly this may lead to a condition called NAION (sudden optic nerve-related vision loss). Inform your doctor before to take Cialis if you have abnormal penis, including curved penis and birth defects of the penis, had coronary artery disease, arrhythmia, angina, heart attack or heart failure, hypo- or hypertension, bleeding, stomach ulcers, diabetes, hyperlipidemia (excess of lipids in the blood), sickle-cell anemia, liver or kidney failure in history.

Contraindications

Prolonged erections or priapism (painful erections lasting more than 6 hours) are also possible. If your erection is longer than 4 hours, seek for immediate medical help as it may permanently damage your penis. Aggravation of heart problems in patients with pre-existing heart disease using Cialis was reported.

Avoid taking Calis with medications such as Erythrityl Tetranitrate, Isosorbide Dinitrate, Isosorbide Mononitrate, Nitroglycerin, Pentaerythritol Tetranitrate. Levels and toxicity of Cialis are increased by erythromycin, ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan) and ritonavir (Norvir).

Levitra (Yellow Tablets)

Common use
Levitra is an oral drug used to treat erectile dysfunction. Sexual stimulation causes the production and release of nitric oxide from the nerves endings of the cavernous bodies of the penis hereby activating enzyme guanylate cyclase. Guanylate cyclase in its turn is responsible for production of cyclic guanosine monophosphate (cGMP). The cGMP causes widening and relaxation of the blood vessels carrying blood to the penis. Levitra prevents phosphodiesterase-5 enzyme from destroying cGMP and thus helps to support blood flow to the penis.

Dosage and direction
The recommended dose of Levitra is 10 mg per day taken an hour before intercourse. If no side effects are experienced the dosage can be increased up to 20 mg. In case of adverse effects the dose is reduced to 5 mg daily. Do not take more than one tab of Levitra a day.

Precautions
Levitra has not been studied in people with cardiovascular disease, so it is preferable to avoid Levitra if in patients who have a stroke or heart failure, or a heart attack in history and especially within last six month. Before to take Levitra inform your doctor if you have kidney or liver problems, a bleeding disorder, stomach ulcer, or an inherited retinal disorder such as retinitis pigmentosa, allergic reaction to this medicine or any other medicines, deformation of the penis such as angulation, cavernous fibrosis (Peyronie's disease), as well as in diseases that contribute to the development of priapism (sickle-cell anemia, multiple myeloma, leukemia, or leukemia).

Contraindications
Levitra is contraindicated in patients with hypersensitivity to its ingredients, ones treated with organic nitrates, in patients under 16 y.o., or those who take HIV protease inhibitors such as indinavir and ritonavir.

Levitra is usually well tolerated and side effects if occur are transient. The most frequent side effects are: headache, flushing (hyperemia of the person); frequent; dizziness, diarrhea phenomenon, nausea, nasal congestion. More rare and uncommon adverse effects are photosensitivity of skin, hypertension, back pain, watery eyes, hypotension, myalgia, priapism.

Drug interaction
Levitra's metabolism is inhibited by erythromycin, ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan) and ritonavir (Norvir). Levitra reduces the concentration of ritonavir and indinavir. In patients treated with nitrates Levitra may aggravate chest pain by increasing heart rate and lowering blood pressure. Levitra is able to exaggerate the blood pressure lowering effects of alpha-blocking drugs (terazosin or Hytrin). Levitra never should be administered in patients who are treated with organic nitrates.

Missed dose
Levitra is taken when needed but not more often than once daily so missed dose is not supposed.
