Abstract: Injectable compositions containing gabapentin and processes for preparing sterile injectable compositions containing gabapentin are discussed. The process includes subjecting the compositions to heat. Heating results in increased production of gabapentin lactam, which has previously been shown to be toxic. Surprisingly, heated injectable compositions containing gabapentin are found to be non-toxic when administered intrathecally. Thus, heating for the purposes of sterilization or to assure sterility provides a viable option in the production of injectable compositions containing gabapentin.

Abstract: Methods for treating epilepsy by administering gabapentin to cerebrospinal fluid and brain tissue of a patient are discussed. Compositions, particularly injectable compositions, containing gabapentin are also discussed. In addition, systems including an implantable device having a pump coupled to a reservoir for housing a composition, a catheter having a proximal end coupled to the pump and having a distal end adapted for administrating a composition to a cerebrospinal fluid of a patient, and a composition containing gabapentin, which composition is housed in the reservoir of the pump, are also discussed.

Abstract: Methods for treating pain by administering gabapentin to cerebrospinal fluid of a patient are discussed. Compositions, particularly injectable compositions, containing gabapentin are also discussed. In addition, systems including an implantable pump having a reservoir for housing a composition, a catheter having a proximal portion coupled to the pump and having a distal portion adapted for administrating a composition to a cerebrospinal fluid of a patient, and a composition containing gabapentin, which composition is housed in the reservoir of the pump, is also discussed.

Abstract: A sympatholytic cardiovascular agent delivered by a drug delivery pump to a central nervous system site to alleviate symptoms and otherwise treat heart failure (HF) and pathologies associated with HF. The drug delivery pump can be external or implantable infusion pump (IIP) coupled with a drug infusion catheter extending to the site. A patient activator can command delivery of a dosage and/or an implantable heart monitor (IHM) coupled with a sensor can detect physiologic parameters associated with HF (or pathologies associated with HF) and trigger dosage delivery. The IIP and IHM can be combined into a single implantable medical device (IMD) or can constitute separate IMDs that communicate by any of known communication mechanisms. The sympatholytic cardiovascular agent is one of the group consisting of an alpha-adrenergic agonist and an alpha2-adrenergic agonist, e.g.

Abstract: A sympatholytic cardiovascular agent delivered by a drug delivery pump to a central nervous system site to alleviate symptoms of acute or chronic cardiac insult or impaired cardiac performance.

Abstract: A system including a reservoir, a pump coupled to the reservoir, a catheter coupled to the pump and adapted for delivering a therapeutic agent to a cerebrospinal fluid of a patient; and an injectable gabapentin composition housed in the reservoir and deliverable through the catheter, is discussed. The injectable gabapentin composition may have reduced tonicity. One such injectable gabapentin composition contains greater than about 30 mg/ml gabapentin and has a tonicity of less than about 900 mOsm. Another such injecable gabapentin composition contains less that 0.9% sodium chloride.

Abstract: Injectable compositions containing gabapentin and having reduced tonicity are discussed. One such injectable gabapentin composition contains greater than about 30 mg/ml gabapentin and has a tonicity of less than about 900 mOsm. Another such injecable gabapentin composition contains less that 0.9% sodium chloride. A process for preparing injectable gabapentin compositions are also discussed. The process includes determining and optionally adjusting tonicity of a gabapentin composition.
