Anxiolytic Drugs: Benzodiazepines and Buspirone
1.2K
Benzodiazepines are a class of anxiolytic drugs known for their rapid efficacy and high therapeutic-to-lethal dose ratio, but with a potential risk of drug dependence. These drugs are lipophilic, allowing for rapid absorption after oral administration, eventually reaching the central nervous system (CNS). Once in the CNS, benzodiazepines bind to the allosteric site of the GABAA receptor. This binding enhances the inhibitory effects of the neurotransmitter GABA. By doing so, they prevent...

Psychosis: Goals of Pharmacotherapy
209
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Anxiolytic Drugs: Overview
483
Anxiolytic drugs are vital in managing anxiety disorders by effectively alleviating symptoms such as excessive fear, tachycardia, and tremors. There are several classes of anxiolytic medications, each with unique mechanisms of action and potential side effects.

Benzodiazepines bind to the GABA-A receptor in the brain, enhancing GABA's interaction. This action reduces neurotransmission, effectively blocking anxiety-associated limbic...

Psychosis and Antipsychotic Drugs: Overview
454
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Nonlinear Pharmacokinetics: Dependence of Elimination Half-Life and Dose Clearance
296
The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.
