    Abstract:
    Drugs containing sulfhydryl groups (thiol drugs) (e.g., penicillamine, captopril, thiopronine) can induce pemphigus in vivo and provoke acantholysis in vitro. Enalapril, like captopril, is an angiotensin-converting enzyme (ACE) inhibitor largely used as an antihypertensive drug; it has recently been reported to induce pemphigus, though it is not a thiol drug. In this study we investigated the possible in vitro acantholytic effect of enalapril on normal human skin from donors. The drug induced severe acantholytic changes of keratinocytes and complete suprabasal splitting at one tenth the concentration required by thiol drugs in similar experiments, even after a shorter period of culture. All skin samples from different donors was highly susceptible to the acantholytic effect of enalapril. In our experience, enalapril is the most powerful acantholytic drug in vitro.
