Intrathecal baclofen is used for severe spasticity of spinal cord origin, that is refractive to maximum doses of oral antispasmodic agents, or who experience intolerable side effects. [21] [22] Baclofen may be used off-label as a treatment for alcohol use disorder to reduce the risk of relapse, and to increase the number of days that a person ...
Intrathecal administration is often used for a single 24-hour dose of analgesia (opioid with local anesthetic). Caution should be exercised with intrathecal opioids due to the risk of late onset hypoventilation. The use of intrathecal morphine may be limited by severe pruritus and urinary retention.

Intrathecal pumps require maintenance and need to be periodically refilled. How frequently this occurs is dependent on several factors, including drug concentration and dosage, and pump size. The refill frequency can range between one and six months for baclofen pumps. [2]
Generally, tapering is done is to avoid or minimize withdrawal symptoms that arise from neurobiological adaptation to the drug. [1] [2] Prescribed psychotropic drugs that may require tapering due to this physical dependence include opioids, [3] [4] [5] selective serotonin reuptake inhibitors, [6] antipsychotics, [7] anticonvulsants, [8] and ...
Other severe side effects include unusual or severe tiredness or weakness, as well as yellowing of the skin or the eyes. [41] When baclofen is administered intrathecally, it may cause CNS depression accompanied with cardiovascular collapse and respiratory failure. Tizanidine may lower blood pressure. This effect can be controlled by ...
Drug administration via the nasal cavity yields rapid drug absorption and therapeutic effects. [33] This is because drug absorption through the nasal passages does not go through the gut before entering capillaries situated at tissue cells and then systemic circulation and such absorption route allows transport of drugs into the central nervous ...
In pharmacokinetics, a maintenance dose is the maintenance rate [mg/h] of drug administration equal to the rate of elimination at steady state. This is not to be confused with dose regimen , which is a type of drug therapy in which the dose [mg] of a drug is given at a regular dosing interval on a repetitive basis.
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
