Doxycycline is well absorbed. After an oral dose of 200 mg of doxycycline, plasma concentrations of the drug reach a maximum of 3 micrograms/mL at 2 hours and are well maintained and thus dosage once daily is usually adequate. Absorption is diminished by the presence of iron, aluminium, calcium and magnesium. Doxycycline is widely distributed into pleural and peritoneal fluid, saliva, semen and prostatic fluid. It passes the placental barrier readily and is also present in the milk of lactating patients.
Fig 1.0 â The structure of the peritoneum and the peritoneal cavity. Note how the visceral layer invaginates to cover the organs. The peritoneal cavity is a potential space between the parietal and visceral peritoneum.It contains only a thin film of peritoneal fluid, which consists of water, electrolytes, leukocytes and antibodies. The fluid serves two main functions: 1  It acts as a lubricant, enabling free movement of the abdominal viscera.he peritoneal cavity is not completely closed in females. The abdominal ostia of the uterine tubes opens into the peritoneal cavity providing a potential pathway between the female genital tract and the peritoneum.
