Adverse drug reactions are usually dose dependent and can be influenced by patientâs characteristics including age and gender and these confounding factors should be considered in clinical practice in the interpretation of research data. Selection of antipsychotic drugs should be on an individual basis. Antipsychotic drugs are commonly used drugs for mental disorders. Antipsychotic medication is associated with the numerous adverse drug effects, ranging from mild and intermittent (e.g., dizziness and nausea) to incapacitating (e.g., extrapyrimidal symptoms) some of which can disrupt an array of physical and psychological systems. Many new antipsychotics drugs/agents have been developed and found to be effective in the treatment of psychiatric disorders, but these drugs also exhibit adverse drug reactions which may affect compliance in psychiatric patients. Mostly atypical antipsychotic medications are in use nowadays as typical antipsychotic drugs are no longer been used for the treatment of psychological disorders. Atypical antipsychotics are second generation antipsychotic drugs that are effective in psychological disorders, but these drugs can cause adverse reactions such as weight gain, dizziness etc, but mostly they can cause extrapyrimidal effects.
