The Introductction of Pregabalin


Pregabalin is a gamma-aminobutyric acid (GABA) analogue with similar structure and action to gabapentin, with antiepileptic, analgesic and anxiolytic activities. The mechanism of the antiepileptic action of pregabalin is unclear. In laboratory studies, pregabalin showed anticonvulsant activity in various epilepsy models; the activity spectrum in animal models was similar to that of gabapentin, but the activity of pregabalin was 3-10 times higher than that of gabapentin


After oral administration, Pregabalin has an onset of action within 30 min and a duration of about 5 h for acute dental pain and 1 week for diabetic neuropathy. The time to peak is about 1h, and the bioavailability is 90%. It is less metabolized in the liver, 92%-99% is excreted in its original form through the kidney, and less than 0.1% of the oral dose is excreted in the feces, with a half-life of 5-6.5h.


The Application & Function of Pregabalin


Indications for pregabalin
1. Neuralgia of diabetic peripheral neuropathy and post-herpetic neuralgia
2. Adjunctive treatment of partial seizures in epilepsy
3. Also used for anxiety disorders, social phobia, arthritis


Oral administration:
1. Adjunctive treatment of partial seizures: (1) 75mg once, twice a day or 50mg once, three times a day. Depending on individual response and tolerance, the maximum amount can be increased to 600mg a day, divided into 2-3 doses. (2) For patients with intractable epilepsy in which other antiepileptic drugs are ineffective, add 150-600 mg of pregabalin a day, divided into 2-3 doses.
2. Neuralgia in diabetic peripheral neuropathy: initial dose of 50 mg once, 3 times a day; may be increased to 100 mg once, 3 times a day within 1 week depending on efficacy and tolerability [2].
3. Post-herpetic neuralgia: initial dose of 75 mg twice a day or 50 mg three times a day; may be increased to 300 mg a day within one week depending on efficacy and tolerability. maintenance dose of 75-150 mg twice a day or 50-100 mg three times a day [3].
4. Generalized anxiety disorder: 300-600mg a day
5. Social phobia: 200mg once, 3 times a day
6. Post-operative dental pain: 300mg once and can be repeated every 6 hours according to the duration of anesthesia.
Dose on dialysis: supplemental dose should be given immediately after hemodialysis
