Erectile dysfunction has been there for a longer time than we know. It was first discovered and mentioned in the manuscripts of Ancient Egypt. Since then, attempts have been continuously made to improve the sexual potential of men. Viagra 150 mg (Sildenafil) is known to many as a drug for the treatment of ED, but the range of its therapeutic possibilities is far wider than imagination.

Pharmacology

Viagra is a powerful phosphodiesterase type 5 (PDE5) inhibitor that prevents the degradation of cyclic guanosine monophosphate (cGMP) messengers. An increase in cGMP modulates cellular events, such as the relaxation of smooth muscle cells. The pharmacological effect of this therapeutic action works by releasing nitric oxide (NO) in the corpora cavernosa with the help of sufficient sexual stimulation. As a result of this, blood flow to the penis is increased and its smooth muscle fibers are relaxed.

Before Taking Viagra 150 mg

First of all, you should stop using Viagra 150 mg pills if you are allergic to Sildenafil or any other PDE5 inhibitor drug. Also, it should not be taken if you are taking medications for pulmonary hypertension.

An individual should not use Viagra 150 mg medicine while taking nitrate drugs such as nitroglycerin or isosorbide dinitrate for the treatment of heart pain. As a result of this joint interaction, vasodilation may increase which can lead to a sharp drop in blood pressure with the possibility of losing consciousness.

Before using Viagra medicine, you should consult with your concerned doctor to collect your medical history in order to ensure that there are no conditions such as:

• Problems in the cardiovascular system such as arrhythmia, arterial hypotension or hypertension, or coronary heart disease
• Problems in the circulatory system
• Retinitis pigmentosa, a type of hereditary eye disease
• Any type of blood disorder like anemia, leukemia, etc.
• Pulmonary veno-occlusive disease or complications of pulmonary hypertension, in which the small pulmonary veins are affected
• Diseases of the liver or kidneys
• Any physical deformation of the penis (Peyronie’s disease)

Viagra medicine is not indeed to be used by women, yet it is important to consult with your doctor before taking Viagra medicine if you are pregnant or planning to conceive, or if you are a breastfeeding mother. Viagra 150 mg tablets are allowed for use from the age of 18. That means children below the age of 18 years should prohibit from its use.

Uses of Viagra 150 mg

Erectile dysfunction is a polyetiological disease and in some cases can be caused by several psychogenic factors that require specialized therapy for proper treatment. However, ED can both cause depression and its consequence.

Various Dosage

The usual recommended dose for most adult patients is 50 mg of Viagra to be taken approximately 1 hour before having any sexual activity or intercourse. Based on efficacy and tolerability, the dose may be increased up to 100 mg or reduced to 25 mg for better outcomes. The maximum recommended daily dose should not exceed 100 mg. The maximum recommended frequency of using any viagra tablet is once a day.

For patients with mild kidney dysfunction, dose adjustment is generally not required. However, patients suffering from severe renal insufficiency may decrease and adjust the dose of Viagra (sildenafil) up to 25 mg.

Since the excretion of the Sildenafil drug is impaired in patients with liver ailments, the dose of Viagra should be optimized by reducing it to 25 mg. A dose adjustment of Viagra is not required for senior citizens above the age of 65 years.

Viagra 150 mg with Other Drugs

Viagra 150 mg medicine can enter into a joint interaction with various other medicines and other substances. In general, it is not recommended to take Viagra with similar medications used for erection problems such as Avanafil (Stendra), Tadalafil (Cialis)), or Vardenafil (Levitra).

You should avoid taking Viagra 150 mg pills if you are also taking nitrate medications for chest pain or heart problems. These may include nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Using both drugs simultaneously can cause a sudden and serious drop in blood pressure, which could be life-threatening.

In addition to that, there are a number of other medicines that can interact with Viagra 150 mg, including:

• Medicines used to treat high blood pressure or a prostate disorder.
• Antifungal agents such as ketoconazole or itraconazole.
• Antiviral drugs for the treatment of HIV/AIDS.
• Avoid taking alcohol while on Viagra medication. If you consume alcohol regularly then try to reduce the quantity.
• Grapefruit or grapefruit juice together with Viagra can increase the toxic effects of the medicine in the system and lead to undesirable effects.
