Step-by-step explanation:
Methylphenidate Hydrochloride - IR & ER
Methylphenidate Hydrochloride is a stimulant drug often used to treat Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy. It is known to increase focus, alertness, and decrease appetite and impulsivity at therapeutic doses. Methylphenidate is available in immediate-release (IR) forms such as Ritalin, which provide quick effects that wear off after a few hours, and extended-release (ER) forms such as Concerta, which are designed to release the medication slowly over time for long-lasting effects. A transdermal patch, Daytrana, provides a long-lasting method of delivery through the skin.
While methylphenidate is not typically used recreationally, it shares some effects with other stimulants such as amphetamines when it is. Methylphenidate is sold under several brand names, each offering different durations of effect to manage the symptoms of ADHD and other conditions it is prescribed for. It is important to use methylphenidate as directed by a medical professional, due to the risks associated with improper use of stimulants, including dependence and other severe side effects.
