Amphetamine causes Hyperpyrexia may be significant, with temperatures above 109 oF
(42.8 C) reported. Temperatures this high are compatible with life and are a contributing cause of death.

------- have been recommended for the treatment of amphetamine-induced psychosis, which is due to excess dopamine.

Theobromine found in:

Theophylline possess similar, but weaker pharmacological activity on
CNS.

Theophylline has a wide therapeutic margin, 10 to 20 μg/mL .

Maintaining therapeutic blood concentration can be difficult because numerous factors as well as other drugs can stimulate or depress theophylline clearance,

Orally administration of theophylline or aminophylline
(theophylline ethylene diamine) can result in death due to cardiac
arrhythmias.

Still diazepam should be given first. If fails to control seizures of Theophylline, phenobarbitone should be administered.

Propranolol or verapamil can usually control the Arrhythmia .
These block the SA and AV nodes, and also restore coronary blood flow by reversing theophylline induced hypotension.

Camphor-containing products are generally considered by the
laypeople to be toxic.

camphor has long been used externally as

Camphorated oil has been the largest single cause of camphor-
related poisonings

Signs and symptoms of camphor poisoning may appear within 30min
min after ingestion, or be delayed for several hours on a full stomach.

Because it is highly lipid soluble, camphor enters the CNS quickly.

Barbiturates have long been used to control convulsions, but
diazepam is generally preferred because it produces less respiratory
depression.

: amobarbital is Short-acting

The short duration of action of certain barbiturates associated with increase toxicity potential

toxic blood concentrations of phenobarbital are more readily
decreased by hemodialysis and alkaline diuresis than similar blood
concentrations of short acting barbiturates
