On December 19, 2018, Pfizer announced a joint merger of their consumer healthcare division with UK pharma giant GlaxoSmithKline; the British company will maintain a controlling share
The company developed and produces medicines and vaccines for a wide range of medical disciplines, including immunology, oncology, cardiology, endocrinology, and neurology.
Peripheral neuropathy is a disorder that occurs when these nerves malfunction because they’re damaged or destroyed. This disrupts the nerves’ normal functioning. They might send signals of pain when there’s nothing causing pain, or they might not send a pain signal even if something is harming you. This can be due to:
an inherited disorder
The disorder is uncomfortable, but treatments can be very helpful. The most important thing to determine is whether peripheral neuropathy is the result of a serious underlying condition.
Discontinue treatment if patients develop severe angioedema. Withdraw treatment gradually over at least 1 week. May cause peripheral oedema. Regular vision check is recommended. May decrease platelet count and prolong PR interval.

Mechanism of Action
Like gabapentin, pregabalin binds to the α2δ (alpha2delta) subunit of the voltage-dependent calcium channel in the central nervous system. This reduces calcium influx into the nerve terminals. Pregabalin also decreases the release of neurotransmitters such as glutamate, noradrenaline, and substance P (Australian Medicines Handbook). Pregabalin increases neuronal GABA levels by producing a dose-dependent increase in glutamic acid decarboxylase activity. Glutamic acid decarboxylase (GAD) is the enzyme that converts the excitatory neurotransmitter glutamate into the inhibitory GABA in a single step. For this reason, pregabalin greatly potentiates benzodiazepines, barbiturates & other depressants.
