Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

8.5K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

783
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Analgesia and Pain Management01:25

Analgesia and Pain Management

1.1K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Targeted Cancer Therapies

8.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Antidepressant Drugs: MAOIs and Other Agents01:23

Antidepressant Drugs: MAOIs and Other Agents

535
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Summary

New migraine treatments targeting 5HT1F receptors (lasmiditan) and melatonin show promise. While PACAP and orexin pathways are under investigation, further research is needed to confirm their efficacy for migraine management.

Area of Science:

  • Neurology
  • Pharmacology
  • Neuroscience

Background:

  • Migraine pathophysiology understanding has advanced CGRP-based treatments.
  • Other molecular targets beyond CGRP are implicated in migraine development.

Purpose of the Study:

  • To review and catalog emerging therapeutic targets for migraine treatment.
  • Focus on novel pathways including 5HT1F, PACAP, melatonin, and orexins.

Main Methods:

  • Literature review of scientific studies.
  • Focused analysis on 5HT1F, PACAP, melatonin, and orexin pathways.
  • Evaluation of clinical trial data and preclinical findings.

Main Results:

  • Lasmiditan (5HT1F agonist) is FDA-approved for acute migraine treatment.
  • PACAP-38 shows potential, but clinical trials for its receptor antagonists yielded mixed results.
  • Melatonin demonstrates a positive trend in randomized controlled trials.
  • Dual orexin receptor antagonists (e.g., filorexant) have shown negative results in human studies.

Conclusions:

  • Lasmiditan and melatonin have demonstrated efficacy, supporting their use in migraine treatment.
  • Ongoing research will clarify the therapeutic potential of PACAP and orexin pathways.
  • Newer targets offer alternative strategies for managing migraine.
