Fosphenytoin is available in forms, such as injectable solutions and capsules, to accommodate various therapeutic requirements and patient preferences.

III. Mechanism of Action: How Fosphenytoin Works

Pharmacodynamics; How Fosphenytoin Interacts with Neurological Processes; Fosphenytoin works by influencing sodium channels in the membranes of neurons, which is a crucial way to reduce hyperexcitable states.

Conversion to Phenytoin and Its Effects; When Fosphenytoin is given it quickly turns into phenytoin, its form. This leads to action and lowers the chances of causing irritation, in blood vessels or local areas.
