Patents by Inventor Pascal Druzgala

Pascal Druzgala has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6869972
    Abstract: The subject invention pertains to novel compounds (and salts thereof), and compositions comprising the compounds, for the treatment of cardiac arrhythmias. The subject invention further concerns methods of making the novel compounds. The novel compounds are rapidly metabolized analogs of amiodarone, having the distinct and advantageous characteristic of being metabolized to a less lipophilic compound. This results in an improved safety profile. The new compounds have particular utility for treating life-threatening ventricular tachyarrhythmias, especially in patients with congestive heart failure (CHF). The compounds also provide effective management for ventricular arrhythmias and supraventricular arrhythmias, including atrial fibrillation and re-entrant tachyarrhythmias involving accessory pathways.

  • Patent number: 6864279
    Abstract: This invention is drawn to compounds which are more easily metabolized by the metabolic drug detoxification systems. Particularly, warfarin analogs which have been designed to include esters within the structure of the compounds are taught. The invention teaches methods of reducing the toxicity of drugs comprising the introduction of ester groups into drugs during the synthesis of the drug. This invention is also drawn to methods of treating coagulation disorders comprising the administration of compounds which have been designed to be metabolized by serum or intracellular hydrolases and esterases. Pharmaceutical compositions of the ester containing warfarin, analogs are also taught.

  • Patent number: 6818782
    Abstract: The subject invention pertains to novel enantiomerically pure compounds, and compositions comprising the compounds, for the treatment of cardiac arrhythmias. The subject invention further concerns a method of making and purifying the compounds. The enantiomerically purified compounds, and compositions of these compounds, exhibit unexpectedly distinct and advantageous characteristics, such as a markedly superior ability to reduce or inhibit ventricular premature beats, as compared to racemic mixtures of the compounds.
