Misoprostol in addition to routine treatment of postpartum hemorrhage: a hospital-based randomized-controlled trial in Karachi, Pakistan.

Background: Postpartum hemorrhage (PPH) remains a major killer of women worldwide. Standard uterotonic treatments used to control postpartum bleeding do not always work and are not always available. Misoprostol's potential as a treatment option for PPH is increasingly known, but its use remains ad hoc and available evidence does not support the safety or efficacy of one particular regimen.

Should domperidone be used for the treatment of gastro-oesophageal reflux in children? Systematic review of randomized controlled trials in children aged 1 month to 11 years old.

Aim: To determine whether there is robust evidence of efficacy for domperidone in reducing the symptoms of gastro-oesophageal reflux (GOR) and gastro-oesophageal reflux disease (GORD) in children.

Methods: Systematic review of randomized controlled trials (RCTs). A search was made of the Cochrane Library Issue 2004 (Central Register of Controlled Trials and Database of Systematic Reviews), Medline (Pub-med) 1966 to present and Embase from 1974 to 2004, and reference citations of the RCTs that had been found electronically.

Clinical pharmacology of ondansetron in postoperative nausea and vomiting.

Ondansetron is a 5-HT3 receptor antagonist which is effective and well tolerated as an antiemetic for emesis induced by cancer chemotherapy and radiation therapy, and in the prevention and treatment of postoperative nausea and vomiting. Ondansetron is rapidly absorbed after oral administration (tmax 1.9 h) with an absolute bioavailability of around 60%.

The role of histamine in the acute inflammatory responses to intradermal platelet activating factor.

1. The role of histamine in PAF-induced acute inflammatory responses (flare and weal) in the skin has been evaluated in a series of three separate studies. 2.

The clinical pharmacology, pharmacokinetics and metabolism of sumatriptan.

Clinical pharmacology studies were undertaken in young healthy volunteers, in a small number of elderly subjects and in migraine subjects during and between attacks. Absorption after subcutaneous and oral administration was rapid. Bioavailability was nearly 100% after subcutaneous administration and averaged 14% after oral administration.

The role of CCK caerulein, and CCK antagonists in nociception.

The octapeptide form of CCK predominates in the central nervous system (CNS) of mammalian species, including man. Many of the physiological roles of CCK in the CNS are unknown, but it is believed to be involved in nociception. CCK is distributed throughout cortical grey matter, periaqueductal grey matter, ventromedial thalamus and spinal dorsal horn, all of which are areas known to be associated with pain modulation.

Inflammatory responses to intradermal injection of platelet activating factor, histamine and prostaglandin E2 in healthy volunteers: a double blind investigation.

1. The local responses to intradermal injection of PAF, histamine and PGE2 were investigated in eight healthy male volunteers. Acute effects were monitored by weal and flare measurement; delayed effects were investigated by pain threshold testing and skinfold thickness measurements.
