CIALIS 20MG: Unraveling the Features and Benefits
Cialis (tadalafil) 20mg is a medication used to treat erectile dysfunction (ED) and also symptoms of benign prostatic hyperplasia (BPH). Here are some important aspects:
1. Mechanism of action
For erectile dysfunction:
- Cialis inhibits the enzyme phosphodiesterase - 5 (PDE - 5). In the penis, this leads to an increase in the levels of cyclic guanosine monophosphate (cGMP). When sexual stimulation occurs, cGMP causes relaxation of the smooth muscles in the penile arteries and the corpus cavernosum, allowing increased blood flow into the penis, which results in an erection.
For BPH:
- By relaxing the smooth muscles in the prostate and bladder neck, it helps to improve urinary flow and reduce the symptoms associated with an enlarged prostate, such as difficulty in starting urination, weak urine stream, and frequent urination.
2. Usage instructions
For erectile dysfunction:
- It is typically taken as needed, at least 30 minutes before sexual activity. However, it can be effective for up to 36 hours, which is why it is sometimes referred to as the "weekend pill."
- The recommended starting dose for most patients is 10mg, but a doctor may prescribe 20mg based on the patient's response and tolerability.
For BPH:
- It is usually taken once daily at a dose of 5mg. In some cases, a doctor may prescribe a 20mg dose for specific patients, but this is less common for BPH treatment alone.
3. Precautions and side effects
Precautions:
- It should not be used by patients taking nitrates (e.g., nitroglycerin) for heart problems, as the combination can cause a dangerous drop in blood pressure.
- People with certain heart conditions, liver or kidney problems may require dose adjustments or close medical monitoring.
Side effects:
- Common side effects may include headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose.
- In rare cases, it may cause more serious side effects such as sudden vision loss or hearing loss.
This medication should only be used under the supervision of a healthcare provider who can determine the appropriate use, dose, and monitor for potential side effects and interactions.
