Antipruritic action of thalidomide
Acta Dermato-Venereologica
|March 18, 2000
Summary
Thalidomide effectively reduced chronic itch in patients with various skin conditions. This study suggests thalidomide acts as a primary antipruritic agent, likely due to its central nervous system depressant effects.
Area of Science:
- Pharmacology
- Dermatology
- Clinical Medicine
Background:
- Chronic pruritus significantly impacts patient quality of life.
- Existing antipruritic treatments have limitations.
- Thalidomide's potential antipruritic effects are not well-established.
Purpose of the Study:
- To investigate the efficacy of thalidomide as a primary antipruritic agent.
- To assess thalidomide's effect on subjective and objective measures of itch.
- To explore the mechanism of thalidomide's antipruritic action.
Main Methods:
- A study involving 11 patients with chronic pruritus from diverse conditions.
- Thalidomide administered at a dosage of 200 mg over two nights.
- Itch assessment via subjective patient ratings (10 cm line) and objective nocturnal scratch movement monitoring.
Main Results:
- Thalidomide significantly decreased both subjective and objective measures of itch.
- No improvement was observed in the underlying pruritic disorders.
- Patients reported drowsiness as a common side effect.
Conclusions:
- Thalidomide demonstrates a primary antipruritic effect.
- The antipruritic action is likely mediated by central nervous system depression.
- Further therapeutic assessment of thalidomide for chronic itch is warranted.

01:15Drugs that Stabilize Microtubules
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
01:15Antihypertensive Drugs: Thiazide-Class Diuretics
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...
01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:17Drugs for Treatment of Diarrhea-Predominant IBS
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...

01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...
01:15Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
