A Systemic Review on Topical Marketed Formulations, Natural Products, and Oral Supplements to Prevent Androgenic Alopecia: A Review

Androgens have an intense consequence on the human scalp and body hair.Scalp hair sprouts fundamentally in awol of androgens whereas the body hair hike is vulnerable to the activity of androgens.Androgenetic alopecia(AGA)invoked as males emulate Alopecia due to the cause of the dynamic reduction of scalp hair.Androgens are medium of terminus growth of hair although the body.Local and system androgens convert the extensive terminal follicles into lesser vellus like structure.The out start of this type of alopecia is intensely irregular and the reason behind this existence of enough circulating steroidal hormones androgens and due to genetic predisposition.Effective treatments are available in the market as well as under clinical and preclinical testing.Many herbal formulations are also available but not FDA approved.Different conventional and NDDS formulations are already available in the market.To avoid various systemic side effects of both Finasteride and Minoxidil,topical formulations and natural products(nutrients,minerals,vitamins)now a days are being widely used to treat Androgenic alopecia.CAM(complementary and alternative medicine)provides the option to elect favorable,low-risk,adjuvant and alternative therapies.Herein,we offer a widespread review of topical marketed formulations,natural products,and CAM treatment options for AGA.

Treatment of eosinophlic esophagitis with swallowed topical corticosteroids

Eosinophilic esophagitis(EoE)is an emerging chronic local immune-mediated disease of the esophagus.Beside proton pump inhibitors and food-restrictiondiets swallowed topical corticosteroids(STC)can be offered as a first line therapy according to current guidelines.This review describes the background and practical management of STCs in EoE.So far,mainly asthma inhalers containing either budesonide or fluticasone have been administered to the esophagus by swallowing these medications“off label”.Recently esophagus-targeted formulations of topical steroids have been developed showing clinicopathological response rates up to 85%-an orodispersible tablet of budesonide has been approved as the first“in label”medication for EoE in Europe in June 2018.Whereas it was shown that disease remission induction of EoE by STCs is highly effective,there is still a lack of data regarding long-term and maintenance therapy.However,current studies on STC maintenance therapy add some movement into the game.

Analysis of docosanol using GC/MS:Method development,validation,and application to ex vivo human skin permeation studies

Docosanol is the only US Food and Drug Administration(FDA)approved over-the-counter topical product for treating recurrent oral-facial herpes simplex labialis.Validated analytical methods for docosanol are required to demonstrate the bioequivalence of docosanol topical products.A gas chromatography/selected ion monitoring mode mass spectrometry(GC/SIM-MS)method was developed and validated for docosanol determination in biological samples.Docosanol and isopropyl palmitate(internal standard)were separated on a high-polarity GC capillary column with(88%cyanopropy)aryl-polysiloxane employed as the stationary phase.The ions of m/z 83 and 256 were selected to monitor docosanol and isopropyl palmitate,respectively;the total run time was 20 min.The GC/SIM-MS method was validated in accordance with US FDA guidelines,and the results met the US FDA acceptance criteria.The docosanol calibration standards were linear in the 100-10000 ng/mL concentration range(R^(2)>0.994).The recoveries for docosanol from the receptor fluid and skin homogenates were>93.2%and>95.8%,respectively.The validated method was successfully applied to analyze ex vivo human cadaver skin permeation samples.On applying Abreva®cream tube and Abreva®cream pump,the amount of docosanol that penetrated human cadaver skin at 48 h was 21.5±7.01 and 24.0±6.95 ng/mg,respectively.Accordingly,we concluded that the validated GC/SIM-MS was sensitive,specific,and suitable for quantifying docosanol as a quality control tool.This method can be used for routine analysis as a costeffective alternative to other techniques.
