No need for that. You can use Unixtime stamps:

pawn Код:

new
    iCanUse[MAX_PLAYERS];

dcmd_ad(playerid, params[])
{
    #pragma unused params

    if(iCanUse[playerid]-gettime() > 0) return SendClientMessage(playerid, 0xFF0000AA, "Please wait before using another Adrenaline Pill!");

    new
        Float:iHealth;

    GetPlayerHealth(playerid, iHealth);

    if(iHealth < 100)
    {
        SetPlayerHealth(playerid, iHealth + 100);
        SendClientMessage(playerid, 0x00FF00AA, "Adrenaline Pill has been utilized!");

        iCanUse[playerid] = gettime() + 60; // 60 seconds
    }
    return 1;
}
