Drugs for sexual impotence - Viagra and Cialis
Sexual impotence is a term that is widely used, sometimes even misused. But in fact, it is synonymous with erectile dysfunction, a disorder characterized by the inability to achieve and maintain an erection satisfactory for sexual activity.
The causes of impotence are numerous. It is often a symptom of atherosclerosis or diabetes, excessive smoking and alcohol, as well as the abuse of certain drugs, not to mention obesity and reduced physical exercise that makes the individual more susceptible to cardiovascular problems and decreased testosterone levels in the body. plasma.
For some years now, very effective drugs have been available to resolve sexual dysfunctions of this type. Unfortunately, in a typically Western style, these products are often thought of as simple solutions to a complex problem, without regard to the root cause of erectile dysfunction.
In addition to the risk of possible dependence on these drugs, side effects must be taken into account, which are usually mild but risky for some individuals.
Treatment for impotence with medication
There are some drugs prescribed for erectile dysfunction, with Viagra and Cialis being the commercial names of the drugs most used for this, with often satisfactory results both in terms of efficacy and tolerability.
The mentioned drugs belong to the category of PDE5 phosphodiesterase inhibitors and contain the active substances sildenafil (Viagra) and tadalafil (Cialis).
The mechanism of action of these drugs is very similar, but tadalafil (Cialis) has a much longer duration of action.
This and other small differences can make a product more or less suitable in relation to the user's health status; for this reason, a medical examination prior to treatment is also advisable.
Establishing a therapeutic path to solving the underlying problems of impotence helps, in many cases, to improve the general state of health and to prevent a long series of other conditions.
How do impotence medications work?
These pharmaceutical drugs inhibit the enzymatic degradation of cGMP, an enzymatic messenger that leads, among other things, to a dilation of penile arterioles, with a consequent increase in turgor and genital organ size.
cGMP is released after an increase in nitric oxide production in response to nerve signals triggered by tactile stimuli from the glans penis and other erogenous zones, or of a visual, auditory, and olfactory nature.
Viagra and Cialis are therefore not aphrodisiac drugs, because they do not increase libido, but make the erection more vigorous and lasting after it is stimulated by sexual desire.
How to take viagra and cialis?
The dosage of drugs to combat impotence differ in several aspects, such as duration of action, side effects and interactions with other drugs. All these parameters must be carefully evaluated before starting therapy.
Viagra
- Take it outside of meals, no more than once a day.
- Take 30 to 60 minutes before sexual activity.
- Effect duration is 4 hours on average.
Cialis
- Take it outside of meals, no more than once a day.
- Take 30 minutes before sexual activity.
- Effect of 36 hours on average.
When should they not be used?
If the man suffers from hypotension (low blood pressure), heart problems (myocardial infarction, angina pectoris, arrhythmias) and kidney problems, use should be with caution.
The importance of a preventive medical examination is also linked to the evaluation of possible interactions with any other drugs taken by the patient, including herbal medicines.
They should never be used together with vasodilators, which are special medications for treating chest pain associated with heart problems. Both actually work by dilating the vessels and this could cause a sharp drop in blood pressure.
Care should also be taken when using alpha-blockers (terazosin, doxasozin, tamsulosin), drugs used in the treatment of prostatic hypertrophy and which, similarly to the previous case, can cause drops in blood pressure. In this case, the doctor will impose certain precautions, such as taking the two medicines at a distance of not less than 4 hours or reducing the dosages.
The only exception is the combination of Cialis and tamsulosin, which do not cause significant side effects.
