With the college entrance examination approaching, some parents are willing to purchase so-called "smart drugs" at high prices online in order to make a final push to improve their children's grades. Not long ago, doctors from the Neurology Department of the Capital Institute of Pediatrics visited the mother of a third year high school student, hoping to prescribe a medication called "Ritalin". The parents revealed that she saw it on some forums, saying that "smart medicine" Ritalin can improve learning status and academic performance, and she also wants her child to give it a try. Is it really so magical that 'smart medicine' has once again come into everyone's sight? Let the pharmacist talk about this "smart medicine" from a professional perspective. It is only suitable for children with ADHD. The so-called smart drugs are actually some psychotropic drugs. The online smart drug Ritalin, whose main component is methylphenidate, is currently one of the main recommended drugs for treating attention deficit hyperactivity disorder (ADHD). Methylphenidate is a dopamine and norepinephrine reuptake inhibitor that can antagonize the serotonin 1 receptor and redistribute vesicular monoamine transporters. For children with ADHD, it can achieve a therapeutic effect of increasing attention by stimulating the brain, but it cannot improve memory or analytical abilities, and will not make normal children smarter. For children who do have attention deficit disorder, it is necessary to seek systematic treatment at a reputable hospital. Long term use of Ritalin (Methylphenidate) in normal individuals is a strictly controlled first class psychotropic drug by the state, and cannot be used for other non medical purposes except for the treatment of indications. The abuse of these drugs can only lead to serious consequences, and in the end, their grades do not improve, but instead affect the health of children, causing lifelong resentment. Many parents and students lack a correct understanding of methylphenidate and blindly believe in so-called "smart drugs", taking risks to improve academic performance, ultimately leading to drug dependence. Youth is an important period that can easily develop into drug addiction. During this period, the reckless use of methylphenidates in order to improve academic performance may have serious adverse effects on personal relationships, academic achievements, and career development in the later stages. To maintain a clear mind and strong learning energy in children, a healthy diet, moderate exercise, and a reasonable schedule are the most important. The abuse of "smart drugs" can lead to death. In recent years, the rapid expansion of methyl phenidate and its analogues in the drug black market has led to multiple poisoning and death incidents. It is even more important to note that blindly taking such drugs does more harm than good, and for healthy individuals, it is undoubtedly drug abuse. Because long-term or high-dose use of these drugs can also cause some psychological symptoms, such as inability to sit still, irritability, movement disorders (convulsions), excitement, insomnia, drowsiness, fatigue, dizziness, depression, emotional instability, disorientation, hallucinations, and even mania, as well as addiction that cannot be ignored. There are also studies indicating that the abuse of stimulants such as methylphenidate can lead to an increase in suicide and drug overdose adverse events. (Outlook New Era Network)
