Drug Name Alesse

Benzodiazepines and phenobarbital augment activation of the GABAA receptor by physiologically released amounts of GABA (B) (see p. 226). Chloride influx is increased, counteracting depolarization. Progabide is a direct GABA-mimetic. Tiagabin blocks removal of GABA from the synaptic cleft by decreasing its re-uptake. Vigabatrin inhibits GABA catabolism.
Endothelial impairment and hence dysfunction has been proven to result from smoking, and nicotine is under discussion as a factor favoring the progression of arteriosclerosis. By releasing epinephrine, it elevates plasma levels of glucose and free fatty acids in the absence of an immediate physiological need for these energy-rich metabolites.

 

For the often intractable childhood epilepsies, various other agents are used, including ACTH and the glucocorticoid, dexamethasone. Multiple (mixed) seizures associated with the slow spike-wave (Lennox–Gastaut) syndrome may respond to valproate, lamotrigine, and felbamate, the latter being restricted to drug-resistant seizures owing to its potentially fatal liver and bone marrow toxicity.
When the drug is distributed faster than it is absorbed, the time course of the plasma level can be described in mathematically simplified form by the Bateman function (k1 and k2 represent the rate constants for absorption and elimination, respectively). B. The velocity of absorption depends on the route of administration.
