Allergic Drug Reactions01:27

Allergic Drug Reactions

1.2K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Desensitization and Tachyphylaxis

2.8K
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

Drug-Receptor Interactions01:29

Drug-Receptor Interactions

7.0K
Drug-receptor interaction describes the binding of receptors by drugs, but not all drug-receptor interactions result in activation and tissue response. For instance, the binding of agonists activates the receptor to generate a cellular reaction, while antagonists bind to receptors without causing their activation.
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue....

Drugs for Treatment of Constipation-Predominant IBS

545
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Drug-Receptor Interaction: Antagonist01:28

Drug-Receptor Interaction: Antagonist

4.3K
An antagonist is a drug that binds strongly to a receptor without activating it. An antagonist prevents other molecules, such as neurotransmitters or hormones, from binding to the receptor and triggering a cellular response. Such interaction effectively hinders the normal physiological processes mediated by the receptor, resulting in various pharmacological effects depending on the specific receptor targeted.
Antagonists can be classified as competitive or noncompetitive based on their...

Drugs for Treatment of Diarrhea-Predominant IBS

476
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Summary

Oral naltrexone, used for alcohol dependence treatment, can cause urticarial rash and angioedema. Distinguishing these from spontaneous urticaria or excipient allergy is crucial.

Area of Science:

  • Pharmacology
  • Allergology
  • Toxicology

Background:

  • Naltrexone is an oral medication used to treat alcohol dependence.
  • Adverse drug reactions can manifest as cutaneous symptoms.
  • Differential diagnosis of drug-induced reactions is essential for patient management.

Observation:

  • Treatment with oral naltrexone has been associated with the development of urticarial rash and angioedema.
  • These reactions can mimic other dermatological conditions.

Findings:

  • Urticarial rash and angioedema are potential side effects of oral naltrexone therapy.
  • Acute spontaneous urticaria and allergic reactions to inactive ingredients (excipients) are key considerations in the differential diagnosis.

Implications:

  • Clinicians should consider oral naltrexone as a potential cause of urticaria and angioedema in patients undergoing treatment for alcohol dependence.
  • Prompt identification and management of naltrexone-induced reactions are necessary.
  • Further investigation may be warranted to differentiate drug-induced reactions from other causes.
