Accidental injection of nimodipine can cause serious (rarely fatal) side effects (such as low blood pressure, slow heartbeat). There were no significant increases in mean flow velocities on TCD on the first day after switching the route of administration to oral administration in either subgroup of patients except for MCA in the CI group (Table 2).

Error bars represent the standard deviation. Delayed cerebral ischemia after subarachnoid hemorrhage: beyond vasospasm and towards a multifactorial pathophysiology. However, in the acute phase, many patients cannot take the oral medication. The need to administer norepinephrine, which often accompanies intravenous administration, initially keeps patients in the ICU. The whiskers represent the 1.5 inter quantile range (IQR). In conclusion, we found no indication of safety concerns when switching from initial intravenous nimodipine administration in the acute phase to subsequent oral administration. If significant differences were to be found, this could be a basis for further investigations, since randomized data are not available at present. (2011) 42:9249.

Soppi V, Karamanakos PN, Koivisto T, Kurki MI, Vanninen R, Jaaskelainen JE, et al.. A randomized outcome study of enteral versus intravenous nimodipine in 171 patients after acute aneurysmal subarachnoid hemorrhage. Despite the known data with regard to bioavailability, to the best of our knowledge, studies investigating parameters at the point of switch from intravenous to oral nimodipine administration are completely missing in the literature (22, 23). Abboud T, Andresen H, Koeppen J, Czorlich P, Duehrsen L, Stenzig J, et al. Analysis of TCD-values of subgroups during the switch of the route of administration. Statistical analysis was performed with paired t-test. Since our patient cohort is heterogeneous including patients with complications as well as uncomplicated courses, all parameters in the subgroups in which complications occurred were systematically examined to increase the sensitivity of the analyses. The aim of this analysis was to systematically evaluate our clinical observations of whether neurological and intensive care parameters change immediately due to the change from i.v.

Nimodipine in aneurysmal subarachnoid hemorrhage: a randomized study of intravenous or peroral administration - clinical article.

Intravenous nimodipine was administered when it was expected that the patient would remain sedated for a longer period of time, primarily in higher-grade SAH patients or patients suffering severe complications like rebleeding, or when oral medication was not safely absorbed enterally due to nausea and vomiting.

There were no significant increases in mean flow velocities on TCD on the first day after switching the route of administration to oral administration in either subgroup of patients except for MCA in the CI group (Table 2). The mean TCD values measured in the course of time during the intensive care stay and especially during the switch are shown in Figures 1C,D. To unveil dosage effects correlation analysis were done. CVS occurred in 30 cases (22.6%), 19 patients (14.3%) suffered from cerebral infarction without CVS (CI), and CVS+CI occurred in 27 cases (20.3%), Table 1. Administration of nimodipine is a well-established treatment modality and can happen orally or intravenously (i.v.) This starting dose was determined, in part, from the adult literature where a regimen of 60 mg every 4 hours (in a typical 70 kg patient) equates to approximately . Our objective was to compare the effectiveness of intravenous and enteral nimodipine in preventing poor outcome from delayed cerebral ischemia in patients with subarachnoid hemorrhage.

Objective: Several guidelines recommend oral administration of nimodipine as vasospasm prophylaxis after aneurysmal subarachnoid hemorrhage (SAH). For the middle cerebral artery, an increase from 62.36 to 71.78 cm/sec could only be detected in the subgroup of patients with infarction.

Analysis of TCD-values during the switch of the route of administration. Due to sedation, repetitive neurological exams cannot be performed to assess clinical deterioration, therefore Transcranial Doppler sonography (TCD) can be used as one of several methods to obtain indication of vasospasms especially in large intracranial arteries (1014). Furthermore, 93 of a total of 124 cerebral vasospasms occurred and 35 of a total of 50 i.a. to oral was considered. Sci Rep. (2020) 10:4764. doi: 10.1038/s41598-020-61513-1, 4. Mean flow velocities of the MCA 24 h before switching to oral administration were 83.82 cm/s (MCA) and 64.83 cm/s (ACA). After the switch, 8 events occurred in the same group, of which 3 were intraarterial spasmolyses with locally administered nimodipine. For a more detailed description of the heterogeneous collective, the above-mentioned subdivision into subgroups was applied; in addition, the values for ACA and MCA are listed separately (Figure 2).

There were no significant increases in mean flow velocities on TCD after the switch from i.v. Cumulative drug dosage over 24 h was calculated to perform possible correlations with measured TCD values (typically one per day). Between a dosage of 200 mg nimodipine orally and 10 mg i.v. Federal government websites often end in .gov or .mil. Some studies showed no significant difference in terms of plasma concentration or efficacy achieved when comparing oral with intravenous administration (3234). We performed a gathered analysis of values from ACA and MCA and also of all values combined to show that even when combining values, no significant change was observed. (2020) 86:E17583. When administered intravenously, there is a reduced risk of lower bioavailability in sedated patients.

Nimodipine belongs to the class of pharmacological agents known as calcium channel blockers. (B) All TCD values independent of their circulation are depicted. Cerebral vasospasm (CVS) and delayed cerebral ischemia (DCI) remain common and severe complications after aneurysmal subarachnoid hemorrhage (SAH) and are jointly responsible for the high morbidity and mortality, which is still above 20% in recent publications (13).

Even though we explicitly looked into groups with complications and compared them with uncomplicated courses, we found no differences.

Depending on the neurological parameters and TCD, the following subgroups were defined to assess whether there were differences within these groups, which would further increase significance: (a) patients who had neither vasospasms nor infarctions, patients in whom either (b) vasospasms or (c) infarctions could be detected and (d) patients in whom both were present.
