Effect of oral cromolyn sodium on CKD-associated pruritus and serum tryptase level: a double-blind placebo-controlled study. [2010.05]
BACKGROUND: Generalized pruritus is a significant complication in end-stage renal disease patients. The mechanism is unknown and most treatments are ineffective. This study is the first clinical trial designed to evaluate the effect of cromolyn sodium (CS) on renal itch... CONCLUSION: CS can significantly reduce the severity of pruritus in HD patients, but this effect is not due to a decrease in serum tryptase level.

Gamma scintigraphy for testing bioequivalence: a case study on two cromolyn sodium nasal spray preparations. [2008.06.05]
The present work was carried out to study the deposition patterns and clearance of technetium-99m (99mTc) DTPA labeled cromolyn sodium (CS) solutions when administered from two different CS nasal products using gamma scintigraphy. Five healthy volunteers received a single dose with complete crossover design involving treatment A (test formulation) and treatment B (reference formulation).
Promising ternary dry powder inhaler formulations of cromolyn sodium: formulation and in vitro-in vivo evaluation. [2007.06]
Glucose monohydrate and sorbitol were evaluated as alternative carriers to a-lactose monohydrate in dry powder inhalations. Cromolyn sodium (CS) - carrier binary formulae were prepared and tested in vitro by aerosolization via a twin stage impinger using three types of inhaler devices; Spinhaler, Aerolizer and Handihaler...
Clinical Trials Related to Cromolyn
Cromoglicate in Psoriasis [Recruiting]
Cromoglicate in Mastocytosis [Recruiting]
The purpose of this exploratory study is to investigate the clinical efficacy of study drug
(LP0074) in the treatment of Mastocytosis. The trial will be performed as a left/right
comparison study in male/female subjects with mastocytosis, in a prospective,
double-blinded, randomised, single centre setting.
Evaluating the Effect of Cromolyn Sodium in Uremic Pruritus [Recruiting]
Pruritus is a major disorder among the skin derangements in advanced renal failure. Recent
information suggests that interactions between dermal mast cells and distal ends of
nonmyelinated C fibers may be important in the precipitation and regulation of the sensory
stimuli. Patients having uremic pruritus have been noted to have increased levels of plasma
histamine and tryptase as well as increased numbers of dermal mast cells. Cromolyn sodium is a
mast cell stabilizing agent that inhibits degranulation of mast cells and the release of
histamine, tryptase, and leukotrienes. It is hypothesized that oral cromolyn sodium may
attenuate uremic pruritus by decreasing serum tryptase level.
An Analysis of the Effect of Topical Cromolyn Sodium on Rosacea-associated Erythema [Recruiting]
This study is designed to investigate whether topical application of a cromolyn sodium
solution is able to decrease the facial redness seen in patients with papulopustular
rosacea. Previous work in the lab of Dr. Di Nardo on mice has suggested that cromolyn may
be able to have this effect. The study will enroll a total of 10 patients. 5 will randomly
be assigned to receive the cromolyn sodium solution, and the other 5 will be randomly
assigned to receive the placebo solution. All participants will be instructed to apply
their assigned solution twice daily to their face. Patients will return to the clinic 3, 6,
and 8 weeks after the distribution of the solutions to measure the efficacy of their
Cromolyn Detection of Silent Aspiration [Not yet recruiting]
The overall purpose of this project is to develop and validate a simple, non-invasive method
to detect aspiration of gastro-intestinal fluid into the respiratory tract. The
investigators will compare the quantity of cromolyn detected in urine collected overnight
after 4 ingestions (at 2h intervals) of a 200 mL of a 1mg/mL solution of cromolyn sodium, by
5 healthy control subjects and 10 patients (3-6 with pulmonary fibrosis; and 3-6 either
awaiting or recently undergone lung transplantation) with clinical and laboratory evidence
of GER (gastroesophageal reflux) with microaspiration.
