Abstract:
In this study, transdermal patches containing Nimesulide were prepared using different ratios of polyvinylpyrrolidone (PVP) and Hydroxy propyl methyl cellulose (HPMC) by solvent evaporation technique using 10%w/w of dibutyl phthalate incorporated as plasticizer. The drug matrix film of PVP and HPMC was casted on a polyvinylalcohol backing membrane that was previously dried at 60⁰C for 6 hrs. All the prepared formulations were subjected to physical studies (moisture content, moisture uptake, Tensile strength, flatness and Drug content determination), in vitro release studies and in vitro skin permeation studies. The physiochemical compatibility of the drug and the polymers studied by IR spectroscopy have absence of any incompatibility. In vitro permeation studies were performed across  skin using a Franz diffusion cell. Variations in drug release profiles among the formulations studied were observed. Based on a physicochemical and in vitro skin permeation study, formulation F1 (PVP/HPMC, 5:1) and F5 (PVP/HPMC, 1:5) were chosen for further in vivo experiments. The anti inflammatory effect and a sustaining action of Nimesulide from the two transdermal patches selected were studied by inducing paw edema in rats with 1% w/v carrageenan solution. Hence, it can be reasonably concluded that Nimesulide can be formulated into the transdermal matrix type patches to sustain its release characteristics.

ABSTRACT
Dandruff and seborrheic dermatitis are the common clinical conditions caused by increased growth of fungi and bacteria on the scalp which results in abnormal proliferation, scaling and flaking of scalp epidermis. In present study an attempt was made to develop hair styling gel of Fluconazole, zinc pyrithione and their combination using different concentration of carbopol 940. The formulations were evaluated and compare for rheology, pH, active content, in vitro drug release, ex vivo drug release, in vitro antidandruff activity and in vivo antidandruff activity. All the formulation are homogenous, transparent and stable but formulation HG1, HG7 and HG11 shows high clarity, optimum rheology, high drug content and  drug release, so these three formulations were evaluated for in vitro antidandruff activity. HG11 shows higher zone of inhibition then HG1 and HG7 therefore HG11 was selected for skin irritation test, in vivo study and stability study. HG11 does not show any skin irritation hence it could be an effective formulation for treatment of dandruff and seborrheic dermatitis as compare to other.

The University Institute of Pharmaceutical Sciences of the Panjab University is a premier institution of Pharmaceutical Education and Research in the country.

National Institute of Nutrition (NIN) was founded by Sir Robert McCarrison in the year 1918 as ‘Beri-Beri’ Enquiry Unit in a single room laboratory at the Pasteur Institute, Coonoor, Tamil Nadu. Within a short span of seven years, this unit blossomed into a "Deficiency Disease Enquiry" and later in 1928, emerged as full-fledged "Nutrition Research Laboratories" (NRL) with Dr.
