The atypical antipsychotics (AAP), also known as second generation antipsychotics (SGAs) and serotonin–dopamine antagonists (SDAs), [1] [2] are a group of antipsychotic drugs (antipsychotic drugs in general are also known as tranquilizers and neuroleptics, although the latter is usually reserved for the typical antipsychotics) largely introduced after the 1970s and used to treat psychiatric ...
The drug regulates behaviour and thoughts, and can also exhibit an anti-depressive effect. [3] [8] The side effect profile is similar to related antipsychotic agents, displaying weight gain, mental distress, and inability to sit still. Other possible symptoms include anticholinergic side effects such as insomnia, blurred vision, and dry mouth.
There is a risk of developing a serious condition called tardive dyskinesia as a side effect of antipsychotics, including typical antipsychotics. The risk of developing tardive dyskinesia after chronic typical antipsychotic usage varies on several factors, such as age and gender, as well as the specific antipsychotic used.
Common side effects include movement problems, sleepiness, dry mouth, low blood pressure upon standing, and increased weight. [6] Serious side effects may include the potentially permanent movement disorder tardive dyskinesia , neuroleptic malignant syndrome , severe lowering of the seizure threshold , and low white blood cell levels .

DRIs may be divisible into two different types with different effects: (1) typical or conventional DRIs like cocaine, WIN-35428 (β-CFT), and methylphenidate that produce potent psychostimulant, euphoric, and reinforcing effects; and (2) atypical DRIs like vanoxerine (GBR-12909), modafinil, benztropine, and bupropion, which do not produce such effects or have greatly reduced such effects.

The prosuicidal effects of benzodiazepines are suspected to be due to a psychiatric disturbance caused by side effects or withdrawal symptoms. [11] Because benzodiazepines in general may be associated with increased suicide risk, care should be taken when prescribing, especially to at-risk patients.
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]
Type A reactions are dosage (concentration) dependent. Usually, this kind of side effect is an extension of an ongoing treatment. Pharmacokinetics and pharmacodynamics are termed toxicokinetics and toxicodynamics in the field of ecotoxicology. Here, the focus is on toxic effects on a wide range of organisms.
