Pruritus Therapeutics Are Effective In Reducing The Release Of Histamine And Treating Itch Or Dermatitis
Pruritus Therapeutics |
Pruritus Therapeutics is the process of treating itch or dermatitis. It is the most common symptom associated with diseases and disorders of the skin and can be extremely debilitating. The pathophysiology of pruritus is complex, and antipruritic therapy may be directed against a number of targets, including the epidermal barrier, immune system or nervous system. The management of itch is usually a combination of drug treatment and other measures, including avoidance, reassurance and topical therapies.
A detailed history and physical
examination should be performed to identify any possible underlying cause. This
will help in instituting a targeted treatment plan and will improve outcomes as
pruritus usually resolves upon exclusion of the underlying disorder. Topical
therapies are the mainstay of therapy for mild and localized itch as it is
generally not responsive to systemic agents.
Several anti-itch drugs are available
for the Pruritus
Therapeutics, most commonly corticosteroids and antihistamines. They
are effective in reducing the release of histamine, an important mediator of
itch. However, the effectiveness of these drugs is limited by their side
effects, such as atrophogenesis and glare, and their short duration of action. Many
patients do not respond to these drugs.
Severe and persistent itch often leads
to secondary lesions such as erythema, erosions, excoriations and crusts. This
can also lead to skin infections that can develop into folliculitis, abscess
and erysipelas. A severe and persistent itch can affect sleep, appetite and
mood.
There is a significant need for new
drugs to treat pruritus, and the current pipeline includes compounds with a variety
of mechanisms. These include inhibitors of the HDAC, MAPK and NMDA receptors
and compounds that target histamine and mast cell activation. There are a
number of experimental neuropeptides with potential antipruritic activity.
