The teaching staff at the College of Pharmacy at the University of Basra, Assistant Professor Dr. Hussain Nasser Al-Salman, published a research paper entitled (Formulation, Development and Characterization of
 Microspheres of Calcium Channel Blocker) in the Indian Journal of Pharmaceutical Negative Results with an impact factor of 1.6 and within the third quartile of Scopas classification
 The research included a study using a new drug delivery technology, such as Nifedipine microspheres, where this study sought to increase the solubility of calcium channel blockers and used at room temperature to dissolve the predetermined weighted amount of nifedipine, ethylcellulose, “polyethylene oxide”, and hydroxypropylmethylcellulose.  (HPMC K15M)” where particle size, bulk density, and compressibility index are used in order to describe “microscopic values ​​useful in predicting flowability.” Microspheres were microinjected to increase the percentage of microspheres production with increasing concentration of ethyl cellulose.  medication to be sure. However, mechanical factors cause loss of the final product and therefore the outcome of the procedure may not be 100%.
