Viagra
Viagra (sildenafil) is a medication primarily prescribed to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). It works by increasing blood flow to the penis, facilitating the achievement and maintenance of an erection.
The mechanism
The active ingredient, sildenafil, relaxes muscles in the blood vessels, increasing blood flow to the penis. This effect can help to facilitate the onset of an erection in response to sexual stimulation.
Sildenafil belongs to the class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. This class of medications targets the blood vessel walls in the penis, specifically the cavernosal arteries. This medication works by inhibiting the PDE5 enzyme, which breaks down cyclic guanosine monophosphate (cGMP), a chemical that relaxes blood vessels and increases blood flow to the penis. By blocking PDE5, sildenafil can help to maintain an erection in response to sexual stimulation.
Benefits
Sildenafil is a PDE5 inhibitor, meaning it works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which breaks down cyclic guanosine monophosphate (cGMP). cGMP is a molecule that relaxes blood vessels and increases blood flow to the penis. By increasing blood flow, sildenafil helps to facilitate the achievement and maintenance of an erection during sexual arousal. This helps to relax the muscles in the blood vessels and allow the penis to achieve an erection.
Sildenafil is available in several forms, including tablets and oral disintegrating tablets. These forms are intended for oral administration and are not recommended for intravenous administration due to potential side effects. It is important to note that sildenafil can be taken with or without food, and combining it with alcohol can result in a significant drop in blood pressure.
It's important to note that sildenafil should only be taken under the guidance of a healthcare professional and not over the counter in some cases. It is not advisable to self-medicate with this medication unless instructed by a healthcare provider.
How to use it
Sildenafil is typically taken as a single dose or as an injection over 10-15 minutes. It can be taken orally, with or without food, as directed by a healthcare provider.
The recommended starting dose of sildenafil for ED is 10mg, taken as needed, approximately 30 minutes before sexual activity. The maximum recommended dosing frequency is once per day, and it should be taken at least 30 minutes before sexual activity.
The dosage of sildenafil for PAH is based on the patient's response and response to treatment. It is recommended to start with a low dose and gradually increase the dose over time. The dose may be decreased as needed to achieve a therapeutic response or increased slowly to achieve a desired response.
It is important to note that sildenafil can only be used as needed, and the maximum recommended dose is usually 10mg.
Side effects
Common side effects of sildenafil include headache, flushing, nasal congestion, dizziness, indigestion, and blurred vision. These side effects are usually mild and short-lived, but they may be more severe in some patients. It is important to report any severe or persistent side effects to the patient's healthcare provider.
It is important to note that the most common side effects of sildenafil are generally mild and transient, and the effects usually subside after the patient completes the treatment. However, if side effects persist or worsen, it is advisable to contact a healthcare professional.
Contraindications
Sildenafil is contraindicated in patients with a history of hypersensitivity to sildenafil or any of the components in the drug.
Interactions
Sildenafil can interact with other medications, including those used to treat pulmonary arterial hypertension, nitrates, and certain antifungal agents.
