Methylphenidate is believed to work by blocking the reuptake of dopamine and norepinephrine by neurons. It is a central nervous system (CNS) stimulant of the phenethylamine and piperidine classes. Despite the claim made by some urban legends, it is not a cocaine derivative nor analog; cocaine is a painkiller and ligand channel blocker with SNDRI action, while Methylphenidate is an NDRI with 2–3 fold selectivity for the dopamine transporter (DAT) over the norepinephrine transporter (NET). Cocaine is also more potent in serotonin transporters (SERTs) than NDRI sites. Buy Concerta online
Methylphenidate was first synthesized in 1944 and was approved for medical use in the United States in 1955. It was originally sold by Swiss company CIBA (now Novartis).

Methylphenidate may also be prescribed for off-label use in treatment-resistant cases of bipolar disorder and major depressive disorder. It can also improve depression in several groups including stroke, cancer, and HIV-positive patients. However, the use of stimulants such as methylphenidate in cases of treatment-resistant depression is controversial. Stimulants may have fewer side-effects than tricyclic antidepressants in the elderly and medically ill. In individuals with terminal cancer, methylphenidate can be used to counteract opioid-induced somnolence, to increase the analgesic effects of opioids, to treat depression, and to improve cognitive function. A 2018 review found low quality evidence supporting its use to treat apathy as seen in Alzheimer’s Disease in addition to slight benefits for cognition and cognitive performance. Buy Concerta online
