Methylphenidate: mechanism of action

It is a mild CNS stimulant with a more pronounced effect on the psyche than on motor activity. The mechanism of its therapeutic effect on attention deficit hyperactivity disorder (ADHD) is not exactly known. It probably works by stimulating the cortex and stimulating activation of the reticular formation. Methylphenidate inhibits the reuptake of norepinephrine and dopamine by presynaptic neurons and increases the release of these monoamines into the extraneuronal space. Methylphenidate is a racemic mixture: the right-hand isomer is pharmacologically more active than the left-hand isomer.

Reasons for this variation may include a person's metabolism, body mass index (BMI), age, health status, and kidney function.

How long does Methylphenidate last?

The immediate-release form is effective for about 4 to 6 hours before a person needs another dose, whereas prolonged-release forms of methylphenidate, such as Concerta, can last 10 to 14 hours. The half-life of Methylphenidate ranges from one to four hours.

What you should know about brand and generic drug alternates.
Prescription drugs are a costly medical expense, especially for the elderly, those who are chronically ill and those with no or minimal drug coverage on their Health Insurance. However, each state in America has a law that allows pharmacists to substitute less expensive generic drugs for many brand name products. Depending on your prescription needs, your savings could be very significant. Before you talk with your doctor or pharmacist about switching, there are things you should know about generic drugs.

What is the difference between a generic and brand name drug?
Nothing except for the name, packaging, and the price, a generic drug is called by its chemical name; manufacturers assign their own brand name. The generic products have the same ingredients. Standard practice and most state laws require that a generic drug be generically equivalent to its brand name counterpart. That is, it must have the same active ingredients, strength, and dosage form, be it a pill, liquid, or injection. The generic drug also must be therapeutically equivalent. It must be the same drug chemically and have the same medical effect.

Do all drugs have generic equivalents?
No. Some drugs are protected by patents and are supplied by only one company. However, when the patent expires, other manufacturers can produce its generic version. Currently, about half the drugs on the market are available in generic form.

Will my doctor automatically prescribe generic drugs?
It depends on the physician. You can ask your doctor to write a prescription permitting substitution of a generic drug product when appropriate or to define the chemical name for the prescription. This will ensure you are purchasing the correct Mexico drug. Generic products will be as effective and less costly. Or, you can order only brand name products if you wish. www.mexicanrxpharm.com Mexico pharmacy offers a wide selection of both Brand Name & Generic Mexico medicine. Our Mexican generic drugs are of the highest quality, selected only from the most reputable manufacturers, and are safe to replace brand name medications costing much more.
