A 2014 review found evidence of drug-seeking behavior, with prescriptions for zolpidem making up 20% of falsified or forged prescriptions.Rodent studies of the tolerance-inducing properties have shown that zolpidem has less tolerance-producing potential than benzodiazepines, but in primates, the tolerance-producing potential of zolpidem was the same as seen with benzodiazepines. Overdose
Overdose can lead to coma or death. When overdose occurs, there are often other drugs in the persons system.Zolpidem overdose can be treated with the GABAA receptor antagonist flumazenil, which displaces zolpidem from its binding site on the GABAA receptor to rapidly reverse the effects of the zolpidem. It is unknown if dialysis is helpful. Detection in body fluids
Zolpidem may be quantitated in blood or plasma to confirm a diagnosis of poisoning in people who are hospitalized, to provide evidence in an impaired driving arrest, or to assist in a medicolegal death investigation. Blood or plasma zolpidem concentrations are usually in a range of 30–300 μg/L in persons receiving the drug therapeutically, 100–700 μg/L in those arrested for impaired driving, and 1000–7000 μg/L in victims of acute overdosage. Analytical techniques, in general, involve gas or liquid chromatography. Pharmacology
Mechanism of action
Zolpidem is a ligand of high-affinity positive modulator sites of GABAA receptors, which enhances GABAergic inhibition of neurotransmission in the central nervous system. It selectively binds to α1 subunits of this pentameric ion channel. Accordingly, it has strong hypnotic properties and weak anxiolytic, myorelaxant, and anticonvulsant properties.
This makes it harder for the baby to latch on properly for feeding. Latching may occur over only part of the areola. This can irritate the nipple more, and may lead to ineffective drainage of breast milk and more pain. Reverse pressure softening (RPS) is a technique that can soften the areola enabling deeper latching and more milk transfer; RPS involves gentle positive pressure in the direction of the chest wall from the fingertips around the areola. Engorgement may begin as a result of several factors such as nipple pain, improper feeding technique, infrequent feeding or infant-mother separation. To prevent or treat engorgement, remove the milk from the breast, by breastfeeding, expressing or pumping. Gentle massage can help start the milk flow and so reduce the pressure. The reduced pressure softens the areola, perhaps even allowing the infant to feed. Warm water or warm compresses and expressing some milk before feeding can also help make breastfeeding more effective. Some researchers have suggested that after breastfeeding, mothers should pump and/or apply cold compresses to reduce swelling pain and vascularity even more. One published study suggested the use of "chilled cabbage leaves" applied to the breasts. Attempts to reproduce this technique met with mixed results. Nonsteroidal anti-inflammatory drugs or paracetamol (acetaminophen) may relieve the pain. A warm shower and using cold compresses to help ease the discomfort. Nipple pain
Sore nipples (nipple pain, or thelalgia) are probably the most common complaint after the birth. They are generally reported by the second day after delivery but improve within 5 days.
