CIALIS 20 MG: Unraveling the Features and Benefits
Guía de Salud Masculina
Cialis (tadalafil) 20 mg is a medication primarily used to treat erectile dysfunction (ED) in men. Here are some important aspects:
1. Mechanism of action
- It works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). In the normal sexual response, nitric oxide is released in the penis during sexual stimulation, which activates a series of biochemical reactions leading to smooth muscle relaxation and increased blood flow into the penis. PDE5 breaks down a chemical called cyclic guanosine monophosphate (cGMP), which is involved in this relaxation process. By inhibiting PDE5, Cialis helps to maintain higher levels of cGMP, allowing for improved blood flow and thus facilitating an erection.
2. Usage instructions
When to take: It can be taken as needed before sexual activity. However, it is important to note that sexual stimulation is still required for the drug to be effective. Some men may choose to take it on a more regular basis, depending on their doctor's advice.
Food and alcohol: It can be taken with or without food. But excessive alcohol consumption may reduce the effectiveness of the medication and may also increase the risk of side effects.
3. Duration of action
- One of the notable features of Cialis is its relatively long duration of action. A 20 - mg dose can be effective for up to 36 hours in some men. This is different from some other ED medications, which may have a shorter window of effectiveness.
Side effects
Common side effects:
- Headache is a relatively common side effect, which may occur in a significant number of users.
- Indigestion, including symptoms such as stomach discomfort, bloating, or acid reflux.
- Back pain can also be experienced by some men taking Cialis.
- Muscle aches, which may range from mild to moderate in severity.
Less common but more serious side effects:
- Sudden vision loss in one or both eyes has been reported rarely. This is a serious side effect that requires immediate medical attention.
- Hearing loss or changes in hearing, including ringing in the ears (tinnitus), although this is also a very rare occurrence.
5. Precautions and contraindications
Medical conditions: Men with certain medical conditions should use Cialis with caution or may be contraindicated from using it. For example, those with severe liver or kidney disease may require dose adjustments or may not be suitable candidates for the drug.
Medication interactions: It can interact with other medications. For instance, taking Cialis with nitrates (such as nitroglycerin, which is often used for heart conditions) is contraindicated because the combination can cause a significant and dangerous drop in blood pressure.
Cialis should only be used under the supervision of a healthcare provider, who can assess a patient's overall health, determine the appropriate dose, and monitor for any potential side effects or interactions.
