ADHD or ADD Medications for Adults and Children: Stimulants, Nonstimulants & More
Vyvanse. Ritalin. Concerta. Adderall. Strattera. And myriad others. The number of ADHD medication options is so large that finding the right treatment feels overwhelming at times. Here, an ADHD specialist explains the options for adults and children in terms we can all understand.
ADHD / ADD Medications for Adults and Children: Which Are Best?
I recently saw a child who, after receiving extensive evaluation, was diagnosed with inattentive attention deficit disorder (ADHD or ADD). In talking with his mother about starting him on the ADHD stimulant medication methylphenidate, I realized that the number of ADHD medication options was confusing. Let’s set the record straight about the process of selecting an ADHD medication
The ADHD medications prescribed to both children and adults are categorized as stimulant — amphetamine or methylphenidate — or non-stimulant. Stimulants are considered the treatment of choice for ADHD. Non-stimulants are prescribed to patients who don’t tolerate or see benefits from stimulants. Certain non-stimulants, particularly alpha agonists, are prescribed with medication to treat symptoms that stimulants do not alleviate. The most popular ADHD medications among ADDitude readers include (in alphabetical order):
- Adderall XR (amphetamine)
- Concerta (methylphenidate)
- Dexedrine (amphetamine)
- Evekeo (amphetamine)
- Focalin XR (dexmethylphenidate)
- Quillivant XR (methylphenidate)
- Ritalin (methylphenidate)
- Strattera (atomoxetine hydrochloride)
- Vyvanse (lisdexamfetamine dimesylate)
Many parents and adults are similarly confused by these and other treatment choices for ADHD. The Food and Drug Administration (FDA) requires that a medication be given a different name according to its form (capsule, tablet, liquid, patch) or release mechanism (released immediately or over an extended period of time).1 Here’s an example: The ADHD medication Ritalin is a tablet that is released immediately into the bloodstream and works for four hours. Ritalin LA, on the other hand, is a capsule that releases over a longer period of time and works for eight hours. Different names, even though both contain the same medicine — methylphenidate.
How Do Stimulant Medications Treat ADHD?
ADHD is a neurologically based disorder, resulting from the deficiency of a neurotransmitter, or a group of neurotransmitters, in specific areas of the brain. Neurotransmitters are chemicals that transmit signals between nerve cells by bridging the synapse (or gap) between them.2
The key neurotransmitter involved is norepinephrine, along with its building blocks, dopa and dopamine. In theory, the primary medications used to treat ADHD stimulate specific cells within the brain to produce more of the deficient neurotransmitter. That’s why these medications are called stimulants — though it’s unknown exactly how they work to relieve ADHD symptoms.
The two main classes of stimulant medications, methylphenidate and dextro-amphetamine — both are generic names — have been used since the 1930s.3 All brand-name stimulants are variations of these two medications. The ADHD medication Adderall is a modification of dextro-amphetamine, for instance, while methylphenidate comes as an immediate-release tablet, a chewable tablet, a liquid, a skin patch, an intermediate-acting (extended-release) tablet, a long-acting (extended-release) capsule, and a long-acting (extended-release) tablet. Each variation has its own name, but the medicine that treats symptoms is the same — methylphenidate.
How is ADHD Medication Dosed?
Parents of children with ADHD ask me: “My child was on Adderall 10 mg, and my doctor changed her prescription to Vyvanse 60 mg. Why was the dose increased?” The reasons for the numbers have to do with target dose and release mechanism.
Target dose: Each product releases a specific amount of medication into the blood over a given period of time. The FDA requires that the number value for each product represent the total amount of the medication in the tablet/liquid/capsule/patch, not the amount in the blood at any one time. Thus, if the medication, let’s say methylphenidate, is in the form of a four-hour tablet, and it releases 5 mg over that time, it is called methylphenidate 5 mg. A capsule of Adderall that releases 10 mg immediately and 10 mg four hours later is called Adderall XR 20. The number is not based on the amount released at any one time, but on the total amount of the medication in the capsule.
Release mechanism: This indicates the length of time a medication will remain available and active. Stimulants come in a variety of forms — tablet, capsule, liquid, skin patch — and release medication in an hour, four hours, or over eight or 12 hours.
How Does Concerta Work? How Is It Different From Other ADHD Medications?
Many people are confused about the ADHD medication Concerta. Designed to last 12 hours, Concerta has a “sponge” on the bottom of the capsule, medication on top, and a tiny hole above the medication. As the capsule passes through the gastrointestinal tract and absorbs moisture, the sponge expands and pushes the medication out of the hole.
The number value assigned to each dose is confusing. Take Concerta 18 mg. If the goal is to release 5 mg consistently every four hours over a 12-hour period, then there needs to be 15 mg in the capsule. However, it takes time for the sponge to become moist enough to start to expand. So an initial release of medication is needed until the sponge starts working. Researchers figured out that it should be 3 mg. Thus, to release 5 mg over 12 hours, one needs the initial 3 mg, plus 5 mg every four hours during the 12 hours. The total amount of medication is 18 mg. That’s why the medication is called Concerta 18.
Same ADHD Medication, Different Formulations
Medications such as methylphenidate and dextro-amphetamine also come in liquid forms. The patient information sheet inside the medication’s box or packaging states how much medication is in each unit of liquid; for example, 5 mg per 5 ml of liquid. Another methylphenidate product — Daytrana4 — is a patch that releases medication through the skin and into the bloodstream. Daytrana 30 mg contains about 30 mg of methylphenidate, and releases about 3.3 mg of it per hour.
Which ADHD Medication is Best?
In short, there’s no way to know which stimulant medication will work “best” for any one person’s ADHD. It’s often related to your history, your genetics, and your or your child’s unique metabolism.
