Shift work sleep disorder

Obstructive sleep apnea (adjunct)

Off-label for ADHD and cognitive enhancement

6. Sympathomimetic Amines

Compounds that mimic the outcomes of the sympathetic anxious system.Chemical Structure: Varied, regularly comparable to endogenous catecholamines.

Primary Examples:

Ephedrine (decongestant, bronchodilator)

Pseudoephedrine (Sudafed – decongestant)

Phenylephrine (decongestant)

Mechanism of Action: Direct or oblique adrenergic receptor agonists.

Medical Applications:

Nasal decongestion

Asthma (historical use)

Hypotension treatment

Weight loss dietary supplements (restricted due to security concerns)

Legitimate Therapeutic Uses

Stimulants are first-line cure for ADHD, with proven efficacy in about 70-80% of patients. They enhance focus, minimize impulsivity, and assist alter emotional responses via modulation of prefrontal cortex function.

Stimulants assist keep wakefulness in prerequisites characterised by means of immoderate sunlight hours sleepiness. Traditional stimulants and eugeroics are each employed, with eugeroics providing elevated security profiles for long-term use.

Certain stimulants, in particular these with noradrenergic pastime like bupropion, are fantastic antidepressants. Traditional stimulants are now and again used as augmenting retailers in treatment-resistant depression.

Historically used for urge for food suppression, stimulants for weight loss are now quite limited due to cardiovascular risks. Phentermine stays on hand for temporary use in weight problems treatment.

The off-label use of stimulants (particularly modafinil and methylphenidate) for cognitive enhancement in wholesome humans stays controversial however is a developing vicinity of lookup and moral discussion.

Xanthine derivatives like theophylline stay in use for respiratory prerequisites regardless of the improvement of extra selective medications.
