Effectiveness Of Saddle Block Vs Spinal Anaesthesia In Turp: An Open Label Randomized Control Trial.

Background: One of the most frequent diseases among male gender is benign prostatic hyperplasia. Transurethral resection of the prostate (TURP) is a minimally invasive procedure for resection of prostate through endoscopic technique. Recently there was a debate on role of saddle block in TURP.

Evaluation of the surface chemistry and drug-polymer interaction of semi-crystalline micro-particles for the development of controlled release formulations.

This research work explores the surface chemistry and drug-polymer interaction in the manufactured controlled release micro-particles. Isoniazid (INH) was used as a model anti-tubercular drug while Eudragit® S100 (S100), Eudragit® L100-55 based co-processed Acryl EZE (EZE) and Ethylcellulose ECN10 (ECN10) were used as polymeric carriers. INH containing micro-particles were prepared using a mini spray dryer B-290 (Buchi, Switzerland).
