Drugs in the parallel market for the treatment of urethral discharge in Dakar: epidemiologic investigation and physicochemical tests.
OBJECTIVE
Sexually transmitted diseases (STDs) constitute a major public health concern in developing countries. Their interest lies mainly in their diagnosis and their early treatment. Owing to lack of health education and poor living conditions inherent in underdevelopment, self-medication is common practice in these Third World countries. Therefore, the illegal sale of drugs is an important phenomenon in Africa and Asia.


METHODS
An investigation, with a view to evaluating the importance of drug sales in the parallel market for the treatment of urethral discharge in Dakar, was carried out in 50 different locations in the working-class districts of the capital from 13 February to 6 March 1997. These drugs, obtained from vendors in the illegal market, were tested and analyzed using the standard physicochemical methods.


RESULTS
The most frequently proposed drugs to treat male urethritis are: ampicillin 250-mg capsules (44%); oxytetracyline 250-mg capsules (24%); and cotrimoxazole 450-mg tablets (12%). In most cases (88%), these drugs were sold unpackaged; 12% were sold in blisters. Furthermore, in 90% of cases, the expiry date was not indicated. The dosage and duration of treatment were correct in only 6% of cases. The physicochemical analysis was based on the external appearance, the identification, and the dosage of the active principle. Of these drugs offered by street vendors, 53.1% had an unusual appearance; they were mainly ampicillin 250 mg (21 of 22 samples) and oxytetracycline 250 mg (6 of 12 samples). Furthermore, all active principles were identified as positive, with the exception of ampicillin 250 mg, for which only one sample of the 22 was positive; the others appeared to be flour, with no trace of the active principle.


CONCLUSIONS
Given the extent of these illegal sales of drug and their harmful consequences for the health of the population, adequate measures should be taken to eradicate this blight. For this mission to succeed, public authorities, health professionals and populations should combine their efforts.
