Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
Drug Dependence01:17

Drug Dependence

Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...
Combined Effects of Drugs: Synergism01:27

Combined Effects of Drugs: Synergism

Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...
Drug Excretion: Miscellaneous Routes01:10

Drug Excretion: Miscellaneous Routes

Drug excretion involves various organs, including the liver, intestines, skin, and eyes. In the case of drugs or toxins, they can be actively secreted into bile by transporters in the hepatocyte's canalicular membrane. These substances enter the GI tract during digestion and may be reabsorbed into the body from the intestine. This process, known as enterohepatic recycling, can significantly prolong the presence and effects of a substance in the body. To interrupt this cycle, specific substances...
Drug Delivery: Miscellaneous Routes01:22

Drug Delivery: Miscellaneous Routes

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection,  and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs through the...
Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Area of Science:

  • Pharmacology
  • Medicinal Chemistry
  • Drug Discovery

Background:

  • Successful drugs require potent pharmacological action and good druggability.
  • Drug promiscuity, acting on multiple targets, contributes to polypharmacology but can cause side effects and impact drug metabolism, pharmacokinetics, and excretion (DMPK).
  • Protein promiscuity, arising from evolutionary adaptations for diverse ligand binding, underlies drug promiscuity due to conserved structural domains and subtle sequence variations.

Purpose of the Study:

  • To review the applications of drug promiscuity in designing drugs for complex diseases.
  • To discuss the manipulation of promiscuity's benefits and drawbacks for enhanced druggability.
  • To explore methods for predicting ligand promiscuity based on target or ligand structures.

Main Methods:

  • Review of existing literature on drug promiscuity.
  • Analysis of promiscuity's role in drug design for various targets (receptors, enzymes, ion channels, cytochrome P450).
  • Discussion of predictive methods for ligand promiscuity.

Main Results:

  • Drug promiscuity presents both opportunities for multi-target therapies and challenges for drug safety and DMPK profiles.
  • Protein structure conservativity and diversity contribute to ligand cross-reactivity and promiscuous drug action.
  • Methods exist to predict ligand promiscuity from structural data.

Conclusions:

  • Managing drug promiscuity is a key goal in drug design to balance therapeutic benefits with safety and efficacy.
  • Understanding protein-ligand interactions is essential for harnessing promiscuity for complex disease treatments.
  • Predictive tools can aid in identifying and optimizing promiscuous or selective drug candidates.
