Viagra, commonly marketed as "The One You Need," is experiencing growing concerns from regulatory hurdles regarding the use of the medication and potential risks related to its use in certain populations. These concerns, primarily compounded concerns over the potential for misuse and misuse-related side effects, have prompted the creation of a ‘Viagra to Treat’ (VHT) system, incorporating the drug into an approved treatment plan for patients.
Viagra, the active ingredient in Viagra, is classified as a phosphodiesterase type 5 (PDE5) inhibitor. This class of medication works by increasing blood flow to the penis during sexual stimulation, facilitating an erection when sexually aroused. It is typically prescribed to men over the age of 18 who may have erectile dysfunction (ED).
Viagra works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5), which is responsible for breaking down cyclic guanosine monophosphate (cGMP). By preventing PDE5 from breaking down cGMP, Viagra helps cGMP levels remain elevated, promoting relaxation and dilation of blood vessels in the penis, leading to an erection. As a result, Viagra can help men with ED achieve and maintain erections during sexual activity.
Viagra was developed in the 1980s from a compound discovered in the 1970s. While being a member of the PDE5 inhibitor class, Viagra was initially prescribed to patients with pulmonary arterial hypertension (PAH) due to its effectiveness in improving exercise capacity and preventing strokes. However, its widespread use during clinical trials and regulatory concerns caused it to go off-label in the 1990s. Over the years, researchers developed a more holistic approach to addressing ED, focusing solely on the therapeutic benefits versus the potential risks.
Viagra's action mechanisms differ from those of other PDE5 inhibitors. cGMP is a molecule that acts as a guanylate cyclase (GC) inhibitor. When cGMP is cGMP-specific, it acts as a cyclic GMP (cGMP-specific phosphodiesterase type 5 (PDE5)) enzyme, which breaks down cGMP and impairs the ability of cGMP to be cycled into the smooth muscles of the penis. Viagra works by inhibiting PDE5, preventing cGMP from being cycled into the smooth muscles of the penis and facilitating a erection.
Viagra is approved to treat various indications, including:
The recommended dosage for most men is one 50 mg tablet (10-14 tablets) taken 30-60 minutes before sexual activity. However, certain individuals may respond differently to the different doses, or the combination of two doses may be appropriate. It is recommended to start with the lowest effective dose (25 mg) and gradually increase to determine the maximum dose required. For those with PAH, the recommended dose may be increased to 100 mg once daily or reduced to 50 mg once daily to maintain efficacy and safety.
It's important to note that Viagra is not a "one you need" medication. It should only be taken under the guidance of a healthcare professional and should not be initiated or stopped abruptly without medical supervision.
The following contraindications apply to Viagra:
Pregnancy and lactation. Pregnant or breastfeeding women should not handle the medication during pregnancy or while breastfeeding. The medication may harm an unborn baby or cause complications during delivery.
The most commonly reported adverse reactions associated with Viagra usage are generally mild and transient. These reactions tend to resolve on their own within a few days, and include:
Common side effects may include:
It's important to note that not all Viagra-related adverse effects are related to the same process or to any specific dosage.
