INTRODUCTION: Enteral nimodipine provides a neuroprotective effect in patients who have experienced an aneurysmal subarachnoid hemorrhage (aSAH). Nimodipine remains the only US Food and Drug Administration-approved medication for aSAH. CONTENT: Nimodipine has been prescribed for patients with aSAH; however, little is known about factors to consider regarding dosing or patient-specific variables that may affect tolerability to nimodipine. Clinical impact of dose or dosing frequency changes has also been much debated based on risk of hypotension with currently approved dosing regimens. CONCLUSION: This review article addresses factors to consider for dosing and administration, pharmacokinetic and pharmacogenetic impact on nimodipine, and, finally, drug interaction considerations to assess as patients are initiated on enteral nimodipine for aSAH.

Tamoxifen, a selective estrogen receptor modulator (SERM) used in breast cancer therapy, requires metabolic activation by CYP3A4 to exert its biological effects. This study evaluated the effects of calcium channel blockers nimodipine, nitrendipine and felodipine on tamoxifen metabolism by studying their interactions with tamoxifen in vitro and in vivo. Rat liver microsomes (RLM) and human liver microsomes (HLM) were used in this study to evaluate the inhibitory potential of nimodipine, nitrendipine and felodipine on tamoxifen metabolism in vitro.

Dengue, a vector-borne acute febrile illness caused by members of the Flavivirus genus, has dramatically increased its occurrence worldwide. Neurological complications of dengue range from 2.63 to 40%, and subarachnoid hemorrhage is a rare, but significant manifestation.

Glioblastoma multiforme (GBM), one of the most malignant tumors of the central nervous system, has a poor prognosis, mainly because of its high recurrence caused by the rapid development of drug resistance to postoperative chemotherapy. Although macroautophagy/autophagy is believed to be a fundamental factor in tumor survival during chemotherapy, there is still a lack of autophagy biomarkers for predicting patient prognosis and chemotherapeutic efficacy in clinical practice. We combined transcriptomic and single-cell sequencing data to identify differentially expressed autophagy-related genes in gliomas.

Aneurysmal subarachnoid hemorrhage (SAH) may be associated with cerebral vasospasm, which can lead to delayed cerebral ischemia, infarction, and worsened functional outcomes. The delayed nature of cerebral ischemia secondary to SAH-related vasculopathy presents a window of opportunity for the evaluation of well tolerated neuroprotective agents administered soon after ictus. Secondary ischemic injury in SAH is associated with increased extracellular glutamate, which can overactivate N-methyl-d-aspartate receptors (NMDARs), thereby triggering NMDAR-mediated cellular damage.

Oral nimodipine is the only drug approved in North America for patients with aneurysmal subarachnoid hemorrhage (aSAH). However, bioavailability is variable and frequently poor, leading to fluctuations in peak plasma concentrations that cause dose-limiting hypotension. Furthermore, administration is problematic in patients who cannot swallow.
