CIALIS 5 MG: All You Need to Know about This Dosage
Guía de Salud Masculina
Cialis (tadalafil) 5 mg is a medication used for the treatment of erectile dysfunction (ED) and also for the management of symptoms of benign prostatic hyperplasia (BPH). Here is some information about it:
1. Mechanism of action
For erectile dysfunction:
- Cialis inhibits the enzyme phosphodiesterase type 5 (PDE5). In the penis, sexual stimulation causes the release of nitric oxide (NO). NO activates guanylate cyclase, which increases the levels of cyclic guanosine monophosphate (cGMP). cGMP relaxes the smooth muscles in the blood vessels of the penis, allowing increased blood flow into the erectile tissues, thus facilitating an erection. PDE5 breaks down cGMP, and by inhibiting PDE5, Cialis helps to maintain higher levels of cGMP, prolonging the vasodilatory effect and improving erectile function.
For BPH:
- In the prostate and bladder, PDE5 inhibitors like Cialis may also act on smooth muscle cells. By relaxing the smooth muscles in the prostate and bladder neck, it can improve urinary flow, reduce urinary symptoms such as hesitancy, and decrease the frequency of nocturia in men with BPH.
Usage
For erectile dysfunction:
- The 5 - mg dose of Cialis can be taken daily as a low - dose, continuous treatment option. This allows for more spontaneous sexual activity compared to higher - dose, on - demand regimens. Some men may start to notice an improvement in erectile function within a few days to weeks of starting the daily 5 - mg dose.
For BPH:
- When used for BPH, the 5 - mg daily dose helps to relieve the obstructive and irritative urinary symptoms associated with an enlarged prostate over time.
Side effects
Common side effects:
- Headache, indigestion, back pain, muscle aches, flushing (redness of the skin), and nasal congestion are relatively common. These side effects are usually mild to moderate and tend to resolve on their own over time.
Less common but more serious side effects:
- Sudden vision loss or changes in vision (although very rare) in one or both eyes, which may be a sign of a serious eye problem called non - arteritic anterior ischemic optic neuropathy (NAION). There may also be an increased risk of hearing loss, although this is also very uncommon.
Precautions
Medical history:
- Men should inform their healthcare provider about any pre - existing medical conditions, especially heart problems (such as heart failure, recent heart attack, or unstable angina), low blood pressure, liver or kidney disease, and a history of stroke.
Drug interactions:
- Cialis can interact with certain medications, such as nitrates (used for treating chest pain or angina). Taking Cialis with nitrates can cause a significant and potentially dangerous drop in blood pressure. Other medications like alpha - blockers (used for BPH or high blood pressure) may also interact, and the dosages may need to be adjusted carefully.
It is important that Cialis is used under the supervision of a healthcare provider, who can determine the appropriate use, monitor for side effects, and ensure its safety and effectiveness for an individual patient.
