Abstract
Survival after severe traumatic brain injury (TBI) depends on minimizing or avoiding secondary insults to the brain. Overproduction of reactive oxygen species (ROS) and Ca2+ influx at the damaged site are the key factors that cause secondary injury upon TBI. Herein, a TBI-targeted lipid covered radical scavenger nanoparticle is developed to deliver nimodipine (Np) (CL-PPS/Np), in order to inhibit Ca2+ influx in neurons by Np and to scavenge ROS in the brain trauma microenvironment by poly(propylene sulfide)60 (PPS60 ) and thus prevent TBI-associated secondary injury. In post-TBI models, CL-PPS/Np effectively accumulates into the wound cavity and prolongs the time of systemic circulation of Np. CL-PPS/Np can markedly protect the integrity of blood-brain barrier, prevent brain edema, reduce cell death and inflammatory responses, and promote functional recovery after TBI. These findings may provide a new therapy for TBI to prevent the spread of the secondary injury.

Li F, Fei Q, Mao D, Si Q, Dai M, Ma Q, Zhang H, Bai L, He N. Comparative Pharmacokinetics of Nimodipine in Rat Plasma and Tissues Following Intraocular, Intragastric, and Intravenous Administration. AAPS PharmSciTech 2020; 21:234. [PMID: 32794077 DOI: 10.1208/s12249-020-01772-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 07/22/2020] [Indexed: 11/30/2022] Open
Abstract
We investigated the pharmacokinetics of nimodipine (NMD) in rats plasma and tissues following intraocular (io), intragastric (ig), and intravenous (iv) administration at doses of 5.0 mg/kg io and iv and 10.0 mg/kg ig. After a single dose of NMD, plasma, heart, liver, spleen, lung, kidney, and brain samples were collected at the scheduled time points. The concentration of NMD in rat plasma and tissues was determined by high-performance liquid chromatography, and the main pharmacokinetic parameters were calculated and compared. NMD was rapidly absorbed and reached the maximum plasma concentration in approximately 5 min after io administration. The absolute bioavailability after io administration was higher than that after ig administration (40.05% vs. 5.67%). There were significant differences in the tissue distribution of NMD with different administration routes. After io administration, NMD was distributed more in the lung, spleen, and brain tissues, and less in the kidney. The maximum drug concentration after io administration in the heart, liver, spleen, lung, kidney, and brain was 1.00, 0.47, 2.02, 1.47, 0.22, and 5.79 times higher than that after via ig administration, and the area under the curve value was 0.59, 0.78, 1.71, 1.84, 0.25, and 4.59 times greater, respectively. Nimodipine appears to achieve systemic effects via io administration. Compared with ig, io administration could significantly increase NMD distribution in the brain tissue, indicating that NMD could be delivered to the brain via io administration.

Abstract
Prior research on 3-week hydrocephalic rats showed that behavioral deficits and white matter damage could be reduced by treatment with Ca2+ channel blocker nimodipine. We hypothesized that treatment with nimodipine would be also beneficial to young ferrets with kaolin-induced hydrocephalus. Hydrocephalus was induced at 14 days of age and animals were treated either with vehicle, low dose nimodipine (3.2 mg/kg/day), or high dose nimodipine (16 mg/kg/day) for 2 weeks from 38 to 52 days age. Hydrocephalic ferrets developed progressive ventriculomegaly, behavioral changes, and in some cases cortical blindness. These changes were not ameliorated by nimodipine. Histological examination showed damage in periventricular white matter, corpus callosum thinning, axonal damage, reactive astroglial changes, and suppressed cell proliferation compared to non-hydrocephalic controls. Treatment with nimodipine was not beneficial for any of the pathological changes mentioned above; only low dose nimodipine treatment was associated with normalized content of glial fibrillary acidic protein, despite larger ventricles. We conclude that young hydrocephalic ferrets experience behavioral impairments and structural brain damage that are not consistently improved by intermittent nimodipine treatment. Continuous delivery should be considered in further preclinical studies.
