View Full Version : Metadate Cd Comparable To Ritalin For Adhd

04-24-03, 08:09 AM
Two studies published in The Journal of Applied Research showed that once-daily Metadate CD (methylphenidate HCl, USP) 20-mg extended-release capsules provided a treatment comparable to Ritalin for attention deficit hyperactivity disorder (ADHD). Results showed ADHD symptom control during a nine-hour observation period in children ages six and older.

Is this drug the same thing as ritalin? If so, what is the difference between metadata and Concerta?

According to Lawrence Weathers, Ph.D.m author of ADHD: A Path to Success

"Metadate a reformulation of Ritalin for sustained delivery...
Because it releases over several hours it delivers a smoother dose throughout the day. It comes in 10 and 20 mg tablets.

Sustained delivery can be important for kids with after-school activities and homework. Once-a-day medication for ADHD can help to eliminate the feelings of embarrassment that children may feel when taking medication during of the school day or after-school activities.

Metadate seems to be superior to Ritalin Sustained Release because Ritalin seems to lose its effectiveness in about 6 hours.

Like Ritalin the most common side effects reported were headache, loss of appetite, abdominal pain and insomnia. Other side effects are reduced stature, ticks, "zombie" demeanor, stomach aches, moodiness and death.

There are some disadvantages:

You canít cut the pill (or chew it) because that will destroy the release mechanism.

You canít control the dosing to account for mealtimes; patients are not likely to feel hungry until the entire dose wears off.

It is similar to Adderall, and Concerta. Both may be preferred to Ritalin because of their longer, more even action."

Big, I have been trying metadate CD to see if a longer acting med would be simpler that ritalin. It seems ok, but I am beginning to think plain ritalin fits most adults better, with oddball work and social timing and needs. concerta seemed to do nothing, nor did stratterra, and ritalin sr took two hours to do anything, and seemed about half of the calming effect I usually got with regular generic ritalin. I just got a new doc, and am wonderint if I should try adderrall xr, as it has been approved for adult add. Any thoughts? thanks
