Q) What is Ritalin?
A) Ritalin (methylphenidate) is a central nervous system stimulant, similar to amphetamines in the nature and duration of its effects. It is believed that it works by activating the brain stem arousal system and cortex. Pharmacologically, it works on the neurotransmitter dopamine, and in that respect resembles the stimulant characteristics of cocaine. When taken in accordance with usual prescription instructions, it would be classified as having mild to moderate stimulant properties, but when snorted or injected it has a strong stimulant effect. Ritalin is manufactured by CIBA-Geigy Corporation, and is supplied in 5 mg., 10 mg., and 20 mg. tablets, and in a sustained release form, Ritalin SR as 20 mg. tablets. It is readily water soluble and is intended for oral use. It is a Schedule II Controlled Substance under both the federal and Indiana Controlled Substances Acts. Since Ritalin is a Schedule II Controlled Substance, the federal government strictly regulates the amount that may be manufactured, through a system of rigid manufacturing quotas.
Q) How is Ritalin used?
A) When abused, Ritalin tablets are taken orally, crushed and then snorted, or dissolved in water and "cooked" for intravenous injection. There are numerous reports in medical journals about permanent and irreversible lung tissue damage related to injection of crushed Ritalin tablets.
In order to make the 5- to 20 mg. dose tablets large enough to handle easily, at least 100 mg. of "inert ingredients" are added to the tablets to increase their size. Depending upon size and formulation, the following inert ingredients are found in Ritalin tablets, according to the manufacturer: lactose, starch, polyethelene glycol, magnesium stearate, sucrose, talc, cellulose, mineral oil, and various dyes and conditioning agents. While these ingredients are "inert" when taken by mouth, they can cause serious problems when injected or snorted.
Q) What are the side effects of Ritalin?
A) The side effects of Ritalin addiction include but are not limited to:
High doses of stimulants produce a predictable set of symptoms that include:
While death due to non-medical use of Ritalin is not common, it has been known to occur.
Q) What are the symptoms of Ritalin overdose?
A) Symptoms of Ritalin overdose may include: Agitation, confusion, convulsions (may be followed by coma), delirium, dryness of mucous membranes, enlarging of the pupil of the eye, exaggerated feeling of elation, extremely elevated body temperature, flushing, hallucinations, headache, high blood pressure, irregular or rapid heartbeat, muscle twitching, sweating, tremors, vomiting. A growing number of youngsters taking the drug Ritalin® (methylphenidate) experience overdose, researchers report. The study looked at the frequency of Ritalin overdose cases reported to a regional poison control center in Detroit. Children ages 6 to 9 years were at the greatest risk of overdose, compared with other age groups. Over a two-year period, 289 cases were reported. Of these, 31% developed symptoms. Most common adverse effects included tachycardia, agitation and lethargy. Most cases were due to parents or caregivers unintentionally giving patients excessive amounts of the drug.
