An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
Animal models are used to learn more about a disease, its diagnosis and its treatment, with animal models predicting human toxicity in up to 71% of cases. [1] The human equivalent dose (HED) or human equivalent concentration (HEC) is the quantity of a chemical that, when administered to humans, produces an effect equal to that produced in test animals by a smaller dose.

The stimulants are the first line of treatment for ADHD, with proven efficacy, but they do fail in up to 20% of cases, even in patients without tic disorders. [271] Current prescribed stimulant medications include: methylphenidate, dextroamphetamine, and mixed amphetamine salts . Other medications can be used when stimulants are not an option.
Stimulants can affect various functions, including arousal, attention, the reward system, learning, memory, and emotion. Effects range from mild stimulation to euphoria, depending on the specific drug, dose, route of administration, and inter-individual characteristics. Stimulants have a long history of use, both for medical and non-medical ...
There are indications suggesting that stimulant therapy for children and adolescents should be stopped periodically to assess continuing need for medication, decrease possible growth delay, and reduce tolerance. [291] [292] Although potentially addictive at high doses, [293] [294] stimulants used to treat ADHD have low potential for abuse. [259]
A stimulant is a drug that stimulates the central nervous system, increasing arousal, attention and endurance. Stimulants are used in psychiatry to treat attention deficit-hyperactivity disorder. Because the medications can be addictive, patients with a history of drug abuse are typically monitored closely or treated with a non-stimulant.
To avoid toxicity and risk of side effects, FDA guidelines recommend an initial dose of methamphetamine at doses 5–10 mg/day for ADHD in adults and children over six years of age, and may be increased at weekly intervals of 5 mg, up to 25 mg/day, until optimum clinical response is found; the usual effective dose is around 20–25 mg/day.
Guanfacine, sold under the brand name Tenex (immediate-release) and Intuniv (extended-release) among others, is an oral alpha-2a agonist medication used to treat attention deficit hyperactivity disorder (ADHD) and high blood pressure.
