  • 1. METHAMPHETAMINE
  • 2. › Methamphetamine also known meth, N- methylamphetamine is a psychostimulantof the amphetamine class of drugs. This synthetic stimulant affects the central nervoussystem.› Street names:-ice, crystal, glass, tik, chalk,crank,yaba,speed, Poor Mans Cocaine,etc.› It causes the release of the neurotransmitters dopamine, norepinephrine and serotoninand activates the cardiovascular and central nervous systems.› Methamphetamine and its metabolite amphetamine are structurally related, differingonly by the presence of a methyl group.› White or off-white powder, odorless, bitter-tasting.› Schedule II drug.› Sold under the name Desoxyn.› Attention deficit hyperactivity disorder(ADHD)in children.› Short term treatment of obesity.› Also prescribed off-label for narcolepsy.
  • 3. › Following oral administration, methamphetamine is readily absorbed into thebloodstream.› Methamphetamines high lipophilicity also allows it to cross the blood brainbarrier faster than other stimulants, where it is more stable against degradationby monoamine oxidase (MAO).› In the brain, a primary action of methamphetamine is to elevate the levels ofextracellular monoamine neurotransmitters (dopamine, serotonin, norepinephrine)by promoting their release from the nerve endings.› However it is not clear how methamphetamine causes neurotransmitter release, but itappears to involve redistribution of neurotransmitters from synaptic vesicles (via thevesicular monoamine transporter VMAT2) to the neuronal cytoplasm and the reversetransport of neurotransmitters through the plasma membrane transporter into theextracellular space.› This inversion leads to a release of these transmitters from the vesicles to thecytoplasm and from the cytoplasm to the synapse
  • 4. Attention deficit hyperactivity disorder (ADHD)› Generally seen in children, but teenagers and adults also show ADHD.› Difficulty paying attention and focusing, sitting still, depression, lack of sleep,learning disabilities, behavior problems› Affects 3 - 5% of school children. ADHD is diagnosed much more often inboys than in girls.› Desoxyn is prescribed to treat ADHD in children six years old and older.› 5 mg Desoxyn once or twice a day is recommended.› It has calming effect when used at the dosage intended.› It helps ADHD patients by giving them improved impulse control, improvedconcentration, decreased irritability, and decreased anxiety.
  • 5. Exogenous Obesity› Desoxyn is also recommended for weight loss.› This class of drugs used in obesity is known as an anorectic.› Desoxyn causes appetite suppression.› One 5 mg tablet should be taken one/half hour before each meal.› Treatment should not exceed a few weeks in duration.Narcolepsy› Narcolepsy is a condition in which the person falls into deep sleep during itsattacks.› Meth is used in treating this condition due to one of its effects of keeping thesenses awake.› Therefore the episodes of deep sleep are diminished during treatment.
  • 6. › Methamphetamine is a highly stimulant drug. It’s effect is similar to cocaine.› It gives feeling of euphoria, increased libido, alertness, concentration, increasedenergy, increased self-esteem, self-confidence.› It is highly addictive drug and it is difficult to quit.› Routes of administration:- Ingestion (Orally), Snorted, Injected, Smoked.› Meth addiction is rapidly spreading in all countries.US population is badly affectedwith meth.› 5.3% of Americans aged 12 and older reported trying methamphetamine at least once.› It is easy to make meth at home or in illegal labs by using chemicals like dilutedHCl,NaOH,Ethyl ether, etc.› In 1970, methamphetamine was regulated in the Controlled Substances Act in the U.S., and a public education campaign was mounted against it.
