Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

Hemorrhoidal crisis.

Intervention(s):

The products under study will be administered, according to the random distribution, by rectal route in the form of suppositories: A) Recombinante Streptokinase suppository 200 000 UI (CIGB, Havana): 1 suppository every 6 hours for 48 hours; B) Suppository Preparation H: 1 suppository every 6 hours for a maximum of 5 days (suspend earlier if: the clinical manifestations disappear [patient evaluated with total response], if the physician decides to perform thrombectomy or other surgical procedure, and if a serious adverse event occurs.

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

PARTIAL Response: Presence of pain and edema but with reduced intensity, and 50 - 69% reduction of the size of the lesion. No RESPONSE: No reduction in pain intensity and / or edema, and reduction of less than 50% of the hemorrhoidal lesion.

Key secondary outcomes:

Clinical response at 72 hours and at the 10th day after starting treatment. Edema, the presence or not will assess through direct physical examination (inspection) of the region. Pain, measured using the same intensity criteria used to assess the adverse events (mild, moderate or severe). Size of the lesion; it is an indirect measure and more objective of the development of edema; for this the patient will be placed in prone position with exposure of the anal part and will be measured (ruler in millimeters) in centimeters (at the inclusion, and at 5 and 10 days after starting treatment) the largest horizontal and vertical diameters of the lesion. Need for surgery (yes/no) at the 10th day after starting treatment
