The specialty pharmaceutical drug maker called Acusphere, Inc. utilizes a porous microparticle technology to create new drugs and reformulate current drugs. Their technological process allows Acusphere to regulate the dimensions and porosity of particles as small as nano- and microparticles in order to specialize them to serve the delivery requirements of various pharmaceuticals. Eligible products include Imagify, a cardiovascular medication used to detect coronary artery illness, as well as Hydrophobic Drug Delivery System or HDDS which transforms drugs that are not easily water soluble into more minute particles. Another candidate is Pulmonary Drug Delivery System or PDDS, which enables or promotes steady delivery of asthma medications.
