Ad
Ad Uses, Dosage, Side Effects, Food Interaction and all others data.
Ad increases the availability of endogenous opioids (enkephalins) by inhibiting the membrane-bound enkephalinase. The enkephalins in turn mediate their effect through δ receptor ( delta opioid receptor) activation that induces a selective increase in Cl absorption by inhibiting adenylate cyclase.
Onset: 30 min (plasma enkephalinase inhibition).

Uses
Ad is used for the symptomatic treatment of acute diarrhea.
Ad is a pure intestinal antisecretory active substance. It decreases the intestinal hypersecretion of water and electrolytes induced by cholera toxin or inflammation and does not have effects on basal secretory activity.
Following oral administration, Ad is rapidly absorbed and then hydrolysed to thiorphan, which is an inhibitor of enkephalinase, a cell membrane peptidase located in various tissues, notably the epithelium of the small intestine. This enzyme contributes both to the hydrolysis of exogenous peptides and to the breakdown of endogenous peptides such as enkephalins. Ad protects enkephalins from enzymatic degradation thereby prolonging their action at enkephalinergic synapses in the small intestine and reducing hypersecretion. Ad exerts rapid antidiarrhoeal action, without modifying the duration of intestinal transit.
Ad is also used to associated treatment for these conditions: Acute Diarrhoea, Diarrhoea

Ad dosage
Adults: One capsule initially, regardless of the time of day. Then one capsule three times daily preferably before the main meals.

The administration of Ad does not modify the usual rehydration regimens. The presence of bloody stools and fever may indicate the presence of invasive bacteria as a reason for diarrhea or the presence of other severe disease. Ad has not been tested in antibiotic-associated diarrhea and should therefore not be administered under these conditions. Caution should be taken in patients with renal or liver impairment.

FAQ
When should I take Ad?
Ad should be taken for acute diarrhoea exactly as your doctor tells you to. It is taken three times daily at regular intervals until the diarrhoea stops (but for no longer than seven days in total). You should give the first dose as soon as possible.
How long does Ad take to work?
Ad is administered by the oral route, is well absorbed from the intestinal tract and is rapidly converted to its active metabolite thiorphan. Peak plasma levels are attained in about an hour and half life of the drug is three hours.
Is Ad antibiotic?
Ad has an anti-secretory effect. It reduces the secretion of water and electrolytes from the intestine. This helps to reduce the amount of fluid loss from the body in diarrhoea.
What are the side effects of Ad?
The most common adverse effect is headache, which occurs in 1–2% of patients. Rashes occur in fewer than 1% of patients. Other described skin reactions include itching, urticaria, angioedema, erythema multiforme, and erythema nodosum.
You should stop giving Ad to your child and see your doctor immediately if your child experiences symptoms of angioedema, such as:
- swollen face, tongue or pharynx
- difficulty to swallow
- hives and difficulties to breath
How do you use Ad?
The Ad should be added to food or mixed with water in a glass or baby bottle. Mix well and give immediately to your child. The recommended daily dose depends on your child's weight: 1.5 mg/kg per dose (corresponding to 1 to 2 sachets), three times daily at regular intervals.
Is Ad safe for breastfeeding?
Apple pectin and activated (medical) charcoal may be taken during breastfeeding. Oral tannin or ethacridine also do not harm the breastfed baby. Loperamide may be prescribed temporarily during breastfeeding if dietary measures are insufficient. Ad should not be used as its safety has not yet been established.
