Psychosis: Goals of Pharmacotherapy
102
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.

Antihypertensive Drugs: Thiazide-Class Diuretics
523
Thiazide diuretics are sulfonamide derivatives featuring a benzothiadiazine ring system in their molecular structure. Based on this structure, thiazide diuretics can be categorized into two groups: thiazide-type and thiazide-like diuretics. Thiazide-type diuretics, including hydrochlorothiazide and chlorothiazide, consist of a benzothiadiazine backbone with an attached sulfonamide group. Thiazide-like diuretics, such as chlorthalidone and indapamide, lack the thiazide ring but demonstrate...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists
215
Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
