Antipsychotic Drugs: Therapeutic Uses and Side Effects
0 Views •
2024
Antipsychotic drugs primarily block dopamine and serotonin receptors and cholinergic, adrenergic, and histaminergic receptors, thereby reducing hallucinations and delusions in conditions like schizophrenia. However, they can trigger unwanted extrapyramidal effects such as dystonias, Parkinson-like symptoms, and tardive dyskinesia. Despite these side effects, antipsychotics are used therapeutically for various purposes, including managing schizophrenia, preventing nausea and vomiting, curbing...

Therapeutic Index

2025
The therapeutic index of a drug is a key parameter in pharmacology that quantifies the relative safety of a drug by calculating the ratio between the dose that causes toxicity in half the population (50%) to the dose that proves to be effective for half the population (50%). It provides a spectrum of doses for a particular drug ranging from effective to potentially toxic. To illustrate, consider an anticoagulant agent like warfarin. It possesses a narrow window within its therapeutic index to...

2016
The goal of this protocol is to use cationic/anionic liposomes with a neuro-targeting peptide as a CNS delivery system to enable siRNA to cross the BBB. The optimization of a delivery system for treatments, like siRNA, would allow for more treatment options for prion and other neurodegenerative diseases.
FAQs
The molecular target engaged by a drug determines which cellular signaling or biological process changes. Receptors can alter signaling, enzymes can modify biochemical reactions, ion channels can influence cellular activity, and transporters can affect movement across cells. Identifying the relevant target helps explain the intended clinical outcome and supports development of more selective therapies.
A treatment must be given at an appropriate dose to produce its intended benefit. Dose selection therefore connects molecular drug action with the physiological or clinical result being measured. It helps researchers determine whether a medication is effective, supports treatment planning, and provides a basis for balancing desired outcomes against adverse effects.
Evaluation compares the beneficial outcome a medication is intended to produce with unwanted effects that may accompany treatment. This comparison shows whether the treatment achieves a useful result without an unacceptable burden of harm. Considering both sides helps researchers and clinicians judge overall treatment value rather than assessing symptom relief or disease change in isolation.
An assessment should examine whether the medication achieves its intended outcome and how quickly that outcome appears. It should also consider how the benefit compares with adverse effects. Together, these observations describe the treatment's practical performance and help determine whether its effects support continued development, dose adjustment, or clinical use.
During drug development, observed benefits provide evidence that a candidate treatment affects the intended physiological or clinical problem. Researchers can use those findings to select doses that produce the desired outcome and to compare benefits with adverse effects. This information helps determine whether a therapy merits further development and how it should be evaluated.
Clinicians and researchers use therapeutic-effect assessments to match a medication with its intended treatment goal, expected timing, and acceptable benefit-risk balance. Evidence about symptom relief, correction of dysfunction, or slowed disease progression can inform treatment choices. This pharmacological context supports safer, more effective therapy planning while keeping unwanted effects under consideration.
