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.

ABSTRACT
Aim of our present study was to formulate the Gelatin Microspheres Loaded with Lisinopril Dihydrate by using Co-acervation phase separation technique for control prolonged release of drug. Micro-particulate drug delivery of Lisinopril Dihydrate was prepared by using a blend of gelatin-carbopol 934P NF and Gelatin-Sodium alginate as release retardant.Lisinopril Dihydrate Microspheres were formulated by using different drug, gelatin-carbopol and gelatin-sodiumalginate in 6 batches was F1, F2, F3, F4, F5 & F6. All the formulations were investigated for various evaluation parameters like particle size, Bulk density, flow behavior, Entrapment efficiency, percentage yield and in vitro drug release etc. All the formulations showed good flow behavior. SEM study revealed that the spheres were almost spherical in shape with smooth surface. In-vitro drug release study showed that by increasing the polymer concentration the drug release of all the formulations were gradually decreased and the optimized formulation (F6) was able to sustain the drug release for 24 hours. So, it was concluded that gelatin microspheres loaded with Lisinopril Dihydrate can be prepared by Coacervation phase seperation  technique and used for sustaining the drug release for prolonged period of time.
