The most disabling form of Parkinsonism is that occurring after encephalitis. It may occur in persons of any age. The results of surgical treatment, which has been used for the most part only for seriously handicapped patients, have been discouraging in general, although in a few isolated circumstances operation has been of dramatic benefit.The solanaceous alkaloids-atropine, stramonium and hyoscine-either in pure forms or in mixed extracts or tinctures - are the best established drugs at present for the treatment of the postencephalitic forms of Parkinsonism. They have not proven too helpful for patients in the older age group with paralysis agitans. The antihistaminic compounds, particularly Benadryl,(R) have been a very valuable addition. They are of greatest value for patients in the older age group. The newer synthetic compounds, Artane(R) and Panparnit,(R) are also valuable additions. Amphetamine and the related and subsequently produced agents in this group are very helpful for patients showing undue fatigue and lethargy. Tolserol(R) is proving helpful, particularly for patients with painful spasms of rigid muscles.

Spasticity is a complex disorder characterized by a velocity-dependent increase in muscle tone associated with exaggerated deep tendon reflexes. It can be caused by numerous diffuse or focal cerebral and spinal pathologic conditions. Spasticity indicates upper motor neuron dysfunction and if severe, can lead to considerable motion restriction and eventually to more serious disability. The therapeutic interventions available to treat spasticity are often of limited benefit. In the last decade, many open-label and several double-blind, placebo-controlled, studies have demonstrated the effectiveness of intramuscular botulinum toxin (BTX) injections for the management of spasticity caused by multiple sclerosis, brain / spinal cord injury, cerebral palsy, and stroke. BTX can also be beneficial in the treatment of spasticity, or a mixture of spasticity and rigidity, in many neurodegenerative conditions; including Parkinson disease, progressive supranuclear palsy, corticobasal degeneration, frontotemporal dementia and parkinsonism linked to chromosome 17, and in various sporadic and familial spinocerebellar ataxia syndromes. Currently, two BTX serotypes, which are serologically different but share a common subunit structure, are commercially available: type A (Botox(R), manufactured by Allergan, Inc, Irvine, California, USA; and Dysport(R), distributed by Beaufour-Ipsen Pharmaceuticals, Paris, France); and type B (manufactured by Elan Corporation, Dublin, Ireland, and available in the United States as MyoBloc(R) and in Europe as NeuroBloc(R)). BTX primarily affects the neuromuscular junction by inhibiting acetylcholine release. Dosages vary considerably depending on the particular preparation used, the muscle injected, the severity of the condition, and the duration of treatment.

Diphenhydramine is an antihistamine with anticholinergic properties, which has been used for the treatment of Parkinson disease (PD) prior to the development of newer agents with better side-effect profiles. However, most of these agents are given orally. Unfortunately, at the time of death, patients with paralysis agitans are no longer able to swallow and they can experience worsening of their tremors. We report the case of 1 patient with congestive heart failure (CHF) and PD who was unable to swallow and developed uncontrollable tremors 24 hours prior to death and whose tremors were successfully treated with diphenhydramine. We feel that in preimminent patients who cannot swallow or may not have perioral endoscopic gastrostomy (PEG)s or feeding tubes, parenteral diphenhydramine may be an appropriate palliative intervention to reduce tremors.

This industry update covers the period from 1 September through 30 September 2017, and is based on information sourced from company press releases, scientific literature, patents and various news websites. The month saw the US FDA approve three new molecular entities, Aliqopa (copanlisib dihydrochloride) (Bayer Healthcare); Solosec (secnidazole) (Symbiomix Therapeutics) and Verzenio (abemaciclib) (Eli Lilly and Co). Intarcia Therapeutics Inc. has its application for approval of a novel drug device combination of exenatide for the treatment of diabetes rejected by FDA but said that it will work to address the concerns and refile the application. The impact of biosimilars in the market is steadily increasing with seven biosimilars approved in the USA and Sandoz hoping to add to this with its announcement that FDA has accepted its Biologics License Application for a biosimilar version of Roche's Rituxan. Circassia announced positive top line results of a respiratory drug, Duaklir (for the treatment of chronic obstructive pulmonary disease) and Sarepta (for its new treatment for Duchenne muscular dystrophy). Axovant Sciences Ltd announced the failure if its drug Intepirdine in the treatment of Alzheimer's, adding to a growing list of drug failures in this area. There were a number of developments in the area of oncology with Bristol-Myers Squibb and Infinity Pharmaceuticals announcing an expansion of their collaboration looking at combination treatments, as well as Eli Lilly and Co's approval for Verzenio. Rani Therapeutics and Intra-Cellular Therapies announced successful funding rounds to support their drug programs. Allergan announced a novel licensing deal for its dry eye drug, Restasis, which it hopes would allow it to stave off patent challenges from several companies looking to develop generic versions of the drug. New research suggests that loss of sense of smell can be linked to an increased risk of developing Parkinson's disease.
