Long lasting tadalafil can last up to 36 hours, what is the impact on the body?
With the aging population, the health issues of middle-aged and elderly men are increasingly receiving social attention. Erectile dysfunction (ED) is one of the most common health problems of middle-aged and elderly people. Affected by aging population, sub-health status and chronic diseases, the incidence of erectile dysfunction (ED) has increased in recent years. As more and more patients become ill, the demand for disease treatment is also increasing. In clinical practice, the main method for treating erectile dysfunction is drug therapy, with tadalafil being one of the most commonly used drugs. Tadalafil, as a PDE5 inhibitor, has the characteristics of small dosage, long half-life, long efficacy, and mild adverse reactions compared to other similar drugs.
Tadalafil
Firstly, we will briefly understand the kinetic and metabolic characteristics of tadalafil.
Among the above-mentioned drug characteristics of Tadalafil, especially the duration of its efficacy, it has always been a topic of concern for everyone. Compared to sildenafil and vardenafil, tadalafil is considered a long-acting PDE5 inhibitor. Pharmacokinetic studies have shown that after oral absorption into the bloodstream, tadalafil maintains its effective blood concentration for a longer period of time. The time required for blood concentration to decrease from the highest concentration to half-life (half-life) is about 17.5 hours, and the total efficacy window is up to 36 hours. The half-lives of sildenafil and vardenafil are about 3.7 hours and 3.9 hours, respectively, which are much smaller than the half-lives and duration of the efficacy of tadalafil.
However, it is worth noting that although the molecular structure of tadalafil has certain characteristics and its pharmacokinetics is superior to similar drugs, drug metabolism studies have shown that tadalafil has a relatively slow absorption rate and a relatively long metabolic time in organisms, which is also one of the reasons why tadalafil's efficacy can be maintained for a long time.
Tadalafil
Research has shown that after absorption into the bloodstream, the peak drug concentration in the blood is about 2 hours, at which point the peak drug concentration is about 378 ng/ml. After about 17.5 hours, the peak drug concentration can still be maintained at about 190ng/ml.
Let's take a look at the relationship between drug metabolism, duration, and health.
The above metabolic characteristics of Tadalafil are closely related to physical health. Because drugs, as foreign compounds from the human body, need to undergo metabolism and excretion after being absorbed into the bloodstream, and the time, speed, and length of "leaving" the human body will have a certain impact on human physiology. Especially for patients with erectile dysfunction, middle-aged and elderly men are the main group. The physiological function of middle-aged and elderly male organs deteriorates to a certain extent with age, leading to a decrease in metabolic and absorption capacity.
That is to say, under the same dosage conditions, the blood drug concentration, half-life, and duration of the drug's efficacy have a more significant impact on the body's physiology than general adult/young men. Therefore, middle-aged and elderly men need to pay more attention to the health issues behind the duration of the drug when using tadalafil.
Tadalafil
Now, the key question is, is it good or bad for health that tadalafil has been effective for so long? Firstly, it should be noted that the efficacy of tadalafil can last up to 36 hours, which is related to the half-life of tadalafil mentioned earlier. Simply put, half-life refers to the time it takes for a drug concentration in the blood to decrease from its maximum to half after it is absorbed into the bloodstream. If this time is too long, it also means that the drug metabolism and absorption are slow, and it stays in the body for a long time. Therefore, generally speaking, drugs with a longer half-life have a longer duration of efficacy.
On the contrary, if the drug is orally absorbed into the blood, the concentration of the drug in the blood will rapidly decrease from the highest to half, which means that the body absorbs and metabolizes the drug quickly, and the drug has a short half-life. This also means that the drug stays in the body for a short time, so the efficacy is relatively short. Pharmacokinetic studies have shown that the half-life of tadalafil is as long as 17.5 hours, and the drug's half-life is generally around 6 hours. Therefore, the rate of absorption of tadalafil by the body's metabolism is relatively slow.
