Analgesic, Anti Depressant, Sleeping Pill, Latest Clasification

Analgesic/painkiller is any member of the group of drugs used to achieve analgesia, relief from pain. Analgesic drugs act in various ways on the peripheral and central nervous systems. They are distinct from anesthetics, which temporarily affected, and in some instances completely eliminate sensation. Analgesics include paracetamol (known in North America as acetaminophen or simply APAP), the nonsteroidal anti-inflammatory drugs (NSAIDs) such as the salicylates, and opioid drugs such as morphine and oxycodone.

When choosing analgesics, the severity and response to other medication determine the choice of agent; the World Health Organization (WHO) pain ladder specifies mild analgesics as its first step.

The number of analgesics and adjunct agents are available for addressing different pain conditions. Following is a complete list of pain medications which includes new drug approvals.

Analgesics and adjunct pain medications share their mechanism of action. They all deliver analgesic effect by interfering with the pain signaling cascade.

Non-Benzodiazepine hypnotics (Z-Drugs)

Z-drugs are structurally unrelated to each other. These medications have largely replaced traditional benzodiazepines in the treatment of insomnia.

Generic Brand Name
Eszopiclone Lunesta
Zaleplon Sonata
Zolpidem Ambien, Intermezzo, Zolpimist

Melatonin receptor agonists

Ramelteon is currently the only FDA-approved melatonin receptor agonist. Ramelteon is used for sleep onset insomnia and has little value for maintaining sleep.

Orexin receptor antagonists

Orexin-receptor antagonists is a novel pharmacologic class of hypnotics. The first – and by far the only – member of this class was approved in 2014.

Generic Brand Name
Suvorexant Belsomra


Benzodiazepine hypnotics are used for the short-term treatment of insomnia. Benzodiazepines produce sedative, hypnotic, anxiolytic, and muscle relaxant effects.

Benzodiazepines shorten sleep latency and reduce the number of awakenings and the time spent in the stage of wakefulness.

All benzodiazepines are controlled substances in schedule IV.

The two classes of psychostimulants indicated for the treatment of ADHD are methylphenidate and amphetamines. Stimulants function by increasing the amount of dopamine and noradrenaline in the brain and stimulating the central nervous system.

Stimulants are the most potent, and also the most effective class of ADHD medications. Stimulants are considered a first-line therapy for controlling ADHD symptoms unless there are contraindications that preclude their use. Methylphenidate and amphetamines are equally effective, with efficacy rates ranging from 70% to 90%

Stimulants are available in many different formulations including short-acting, intermediate-acting, and long-acting preparations.

Non-stimulant medications approved for the treatment of ADHD have the different mode of action compared to psychostimulants and are considered non-addictive with more favorable side effect profiles.

On the other hand, non-stimulants are generally less effective than stimulants in the treatment of ADHD. The non-stimulants are usually considered second- and third-line medications.

Atomoxetine is a selective norepinephrine reuptake inhibitor with a unique mechanism of action. Atomoxetine is thought to have minimal abuse potential and significantly fewer withdrawal symptoms than psychostimulants. The main drawback is that atomoxetine doesn’t directly influence dopamine and it may take several weeks before the drug elicits a therapeutic effect.

Two antihypertensive drugs (alpha-2 noradrenergic agonists) are approved by the FDA to treat ADHD. These drugs reduce activity in the central nervous system but are considered less effective than stimulants. Clonidine and guanfacine are considered relatively safe over the long-term.

Selective Norepinephrine Reuptake Inhibitor
Atomoxetine Strattera
Alpha-2 Noradrenergic Agonists
Clonidine extended-release Kapvay
Guanfacine extended-release Intuniv

“Off-label” Medications

ADHD medications under investigation

Generic name, Class Brand name
(serotonin modulator and stimulator)
Brintellix, Trintellix
(serotonin-norepinephrine-dopamine reuptake inhibitor)
(serotonin-norepinephrine-dopamine reuptake inhibitor )


Common features of all antidepressants:

  • 1. All antidepressants work by increasing the levels of neurotransmitters (chemical messengers) in the brain.
  • 2. Antidepressants are NOT controlled substances.
  • 3. Antidepressants improve depressive symptoms at about the same rate.

New Antidepressants

Generic Name Brand Name
Vortioxetine (serotonin modulator and stimulator) Brintellix, approved September 2013
Levomilnacipran (SNRI) Fetzima, approved July 2013
Vilazodone (SSRI) Viibryd, approved January 2011

SSRIs (Selective Serotonin Reuptake Inhibitors)

Generic Brand Name
Citalopram Celexa
Escitalopram Lexapro, Cipralex
Fluoxetine Prozac, Sarafem; Pexeva
Fluvoxamine Luvox
Paroxetine Paxil, Paxil CR
Sertraline Zoloft

Selective serotonin reuptake inhibitors are the most widely prescribed antidepressants. SSRIs selectively inhibit the reuptake of serotonin resulting in increased serotonin concentration in the brain.
Main beneficial features of SSRIs over older antidepressants (MAOIs and TCAs):

  • Low overdose toxicity potential.
  • Low risk of severe systemic adverse effects, especially anticholinergic and cardiovascular side effects.

The major drawbacks of SSRIs:

  • Sexual dysfunction, which is the most common SSRI-induced side effect that leads to drug discontinuation.

Tricyclics (TCA)

Generic Brand Name
Amitriptyline Elavil, Endep, Levante
Amoxapine Asendin
Clomipramine Anafranil
Desipramine Norpramin, Pertofrane
Dosulepin Prothiaden, Thaden
Doxepin Adapin, Sinequan
Imipramine Tofranil
Lofepramine Gamanil, Lomont
Maprotiline Deprilept, Ludiomil, Psymion
Mianserin Bolvidon, Norval, Tolvan
Nortriptyline Pamelor
Protriptyline Vivactil
Trimipramine Surmontil

Tricyclic antidepressants represent the oldest class of drugs for depression. Currently, TCAs are considered second-line antidepressants in cases when SSRIs are ineffective or as adjunct therapy with newer drugs. TCAs act as non-selective inhibitors of the reuptake of serotonin and norepinephrine.

Advantages of TCAs:

  • Proven efficacy.
  • Low cost.

Drawbacks of TCAs:

  • Adverse effects such as orthostatic hypotension, anticholinergic effects, cardiovascular effects (arrhythmias and tachycardia).
  • Overdose toxicity.

SNRIs (Serotonin and Noradrenaline Reuptake Inhibitors)

Generic Brand Name
Desvenlafaxine Pristiq
Duloxetine Cymbalta
Levomilnacipran Fetzima
Milnacipran Savella
Venlafaxine Effexor, Effexor XR

Unlike SSRI antidepressants SNRIs block the reuptake of both serotonin and noradrenaline. Generally, SNRIs have side effect profile as SSRIs but are more likely to produce anticholinergic side effects.

NaSSA (Noradrenergic and Specific Serotonergic Antidepressant)

Generic Brand Name
Mirtazapine Remeron, Remeron SolTab

Mirtazapine enhances the presynaptic release of serotonin and norepinephrine in the brain. It works via antagonist activity in the presynaptic alpha 2-adrenergic receptors.

NDRIs (Norepinephrine and Dopamine Reuptake Inhibitors)

Generic Brand Name
Bupropion Wellbutrin, Wellbutrin SR, Wellbutrin XL, Zyban; Aplenzin

MAOIs (Monoamine Oxidase Inhibitors)

Generic Brand Name
Isocarboxazid Marplan
Moclobemide Manerix
Phenelzine Nardil
Tranylcypromine Parnate
Selegiline Emsam (transdermal patch)


Monoamine Oxidase Inhibitors (MAOIs) are irreversible inhibitors of the enzyme monoamine oxidase. MAOIs inactivate neurotransmitters norepinephrine, serotonin, and dopamine. Currently, MAOIs have a place in treating Parkinson’s disease, atypical depression, as well as depression that does not respond to other antidepressant drugs.

The main dangers of MAOIs:

  • Dietary restrictions. MAOIs have potentially lethal interactions with foods and drugs containing tyramine. Foods containing tyramine include cheese, smoked meats, and red wine.
  • Potential to cause a hypertensive crisis and serotonin syndrome.
  • Risk of orthostatic hypotension

Advantages of MAOIs:

  • Effective for atypical depression.
  • Highly effective for mood and anxiety disorders.
  • Minimal anticholinergic and antihistamine effects.
  • Inexpensive.

Mood Stabilizers

Some mood stabilizers used to treat depressive symptoms are:

Generic Brand Name
Lithium Eskalith, Lithane, Lithobid
Quetiapine Seroquel, Xeroquel, Ketipinor

Atypical antipsychotics

Certain atypical antipsychotics licensed to treat depression are:
