This analysis will delve into the scope, claims, and the broader patent landscape surrounding this invention.

Background of the Patent

The patent, issued to the inventors, pertains to the development of parenteral benzodiazepine compositions. Benzodiazepines are a class of psychoactive drugs known for their tranquilizing effects and are commonly used in medical settings for various conditions, including anxiety, insomnia, and as pre-anesthetic agents.

Scope of the Patent

The scope of the patent is focused on the formulation and preparation of parenteral (injectable) benzodiazepine compositions. Here are the key aspects:

Composition

The patent describes specific formulations of benzodiazepine compounds that are suitable for parenteral administration. These compositions typically include a benzodiazepine active ingredient, a solvent, and possibly other additives to enhance stability and solubility[5].

Pharmaceutical Formulation

The invention emphasizes the importance of the pharmaceutical formulation in ensuring the stability and efficacy of the benzodiazepine compound when administered parenterally. This includes considerations such as pH levels, solvent systems, and the presence of stabilizers or preservatives[5].

Clinical Applications

The patent implies various clinical applications for these compositions, including use as anxiolytics, sedatives, and pre-anesthetic agents. The parenteral route allows for rapid onset of action, which is crucial in emergency or surgical settings[5].

Claims of the Patent

The patent includes six claims that define the scope of the invention:

Claim 1: General Composition

The first claim describes the general composition of the parenteral benzodiazepine formulation, including the benzodiazepine compound, a solvent, and any additional components necessary for stability and efficacy[5].

Claims 2-4: Specific Formulations

These claims specify different formulations of the benzodiazepine composition, each with particular concentrations of the active ingredient and solvents. For example, one claim might specify a formulation with a certain percentage of benzodiazepine in a specific solvent system[5].

Claims 5-6: Method of Preparation

The final claims outline the methods for preparing these parenteral compositions, including steps for dissolving the benzodiazepine compound in the solvent and any subsequent processing to ensure stability and sterility[5].
