Background:Phosphodiesterase-5 inhibitors (PDE5Is) represent an emerging class of medicines which are commonly used to treat bacterial infections in tropical and subtropical settings. These medications are designed to increase the levels of cyclic guanosine monophosphate (cGMP), which is a potent molecule that is responsible for the relaxation of smooth muscles. By increasing cGMP levels, these medications can help in the management of acute infections caused by susceptible organisms. However, there are currently limited studies on the efficacy and safety of PDE5Is in the context of malaria infection.
Objective:The objective of this study was to assess the efficacy and safety of Doxycycline in the management of malaria, a disease that is common in South Africa. Methods: This retrospective study evaluated data from a single clinical trial in 15 countries including South Africa. The study was conducted in three regions of South Africa: Durban, Johannesburg and Cape Town. The study was conducted between April 2018 and June 2019. The main objective of the study was to assess the efficacy and safety of Doxycycline in the treatment of malaria. Results: The total number of patients included was 514. Of these, 471 (9.5%) were treated with Doxycycline and the remaining were treated with a single oral dose of 100 mg. The most common side effects were headache (n = 1; 37.3%) and nausea (n = 1; 37.3%). The most common adverse events were headache (n = 1; 37.3%), followed by mycotic sepsis (n = 1; 37.3%), dyspepsia (n = 1; 37.3%), urinary tract infection (n = 1; 37.3%) and urinary tract infection plus severe pelvic infection (n = 1; 37.3%). There were no differences in other common adverse events among the 3 treatment groups. Conclusions: Doxycycline is effective in the management of malaria in South Africa. The most common side effects observed among the 3 groups were headache, nausea, and dyspepsia. The most common adverse events were mycotic sepsis and urinary tract infection, which are common side effects observed among the 3 groups. The safety profile of Doxycycline in the treatment of malaria in South Africa is considered to be similar to that found in other countries.
IntroductionMalaria is one of the most prevalent tropical diseases in South Africa and the second most common cause of transmission to humans, but it is not common in this region. It occurs primarily in Africa. This disease is caused by the Plasmodium parasite, which can infect both humans and animals. P. falciparum is a type of malaria parasite that causes severe cases in Africa, including South Africa. malariae is a zoonotic disease which mainly affects pregnant women and children in sub-Saharan Africa, but its incidence has been shown to increase during the past decade. In South Africa, there is an increasing prevalence of P. falciparum infections and an increasing risk of malaria in the region. Despite the increasing incidence, the management of this disease is still challenging and is often associated with complications such as complications from severe pneumonia, neurological complications, and gastrointestinal infections. In South Africa, the treatment for P. falciparum infection includes combination therapy with chloroquine and doxycycline, and antimalarial drugs such as azithromycin and erythromycin.
A study of patients with P. falciparum infection found that the risk of hospitalization with P. falciparum infection was higher with Doxycycline compared to the other PDE5Is. A study of 9,095 patients with P. falciparum infection found that the risk of admission to the intensive care unit (ICU) was 2.7% in those who took Doxycycline compared to 2.6% in those who took an oral treatment of doxycycline. In addition, the incidence of hospitalization for P. falciparum infection was higher in the Doxycycline group. A study of 8,814 patients with P. falciparum infection found that the risk of hospitalization was 1.6% with Doxycycline compared to the other PDE5Is. These results indicate that Doxycycline is effective in treating P. falciparum infection, which is an important consideration for patients who have poor adherence to the treatment regimen.
Doxycycline is the first-line treatment for malaria infection. It is effective for the treatment of malaria by inhibiting the growth of parasites, and is available in the form of oral capsules and tablets.
Doxycycline is an antibiotic commonly used to treat a variety of bacterial infections. It is effective against a wide range of infections, including urinary tract infections (UTIs), respiratory tract infections, acne, and skin infections. Doxycycline is also prescribed for certain types of acne, such as rosacea and rosacea-like infections.
Doxycycline works by inhibiting bacterial protein synthesis. This means it inhibits the growth and reproduction of bacteria, ultimately leading to their death. It is important to note that this antibiotic is not an oral medication and should only be used in a medical context, as it may interact with other medications, such as other antibiotics.
Doxycycline is commonly used for the treatment of a variety of bacterial infections, including respiratory tract infections, acne, and skin infections. It is also prescribed for other conditions, such as urinary tract infections, as well as respiratory tract infections. However, doxycycline is not recommended for patients with severe or chronic kidney disease, as it has a potential for causing kidney failure.
Doxycycline should be taken orally, typically in the form of a tablet. The dosage can be adjusted based on the severity of the infection and the patient's age and condition. It is important to follow the prescribed dosage and complete the full course of treatment. Doxycycline is typically taken for a short duration, typically a few days to a week, depending on the severity of the infection and the patient's response to the medication.
Like all medications, doxycycline can cause side effects, although not everyone will experience them. Common side effects include:
Serious side effects are rare but can occur, including:
The dosage can be adjusted based on the severity of the infection and the patient's response to the medication. The most common starting dose is 1 mg, taken once daily for a week or more, depending on the severity of the infection.
Doxycycline is highly effective against a wide range of bacterial infections, including UTIs, acne, and rosacea. It is also used to treat other types of infections, such as Lyme disease and Rocky Mountain spotted fever.
If the infection is severe or if it has an identifiable cause, Doxycycline may be prescribed for acute infections or as a maintenance treatment option. If you are concerned about potential side effects, it is important to discuss the potential risks and benefits of using Doxycycline with your healthcare provider.
Like all medications, doxycycline can cause side effects. While rare, these side effects can include:
Malaria is a serious tropical disease spread by mosquitoes. If it isn’t diagnosed and treated promptly, it can be fatal.
A single mosquito bite is all it takes for someone to become infected.
Symptoms of malaria
It’s important to be aware of the symptoms of malaria if you’re travelling to areas where there’s a high risk of the disease. Symptoms include:
a high temperature (fever) sweats and chills headaches vomiting muscle pains diarrhoea Symptoms usually appear between 7 and 18 days after becoming infected, but in some cases the symptoms may not appear for up to a year, or occasionally even longer.
When to seek medical attention
Seek medical help immediately if you develop symptoms of malaria during or after a visit to an area where the disease is found.
Malaria risk areas
Malaria is found in more than 100 countries, mainly in tropical regions of the world, including:
large areas of Africa and Asia Central and South America Haiti and the Dominican Republic parts of the Middle East some Pacific islands

Preventing malaria
Many cases of malaria can be avoided. An easy way to remember is the ABCD approach to prevention:
Awareness of risk – find out whether you’re at risk of getting malaria before travelling Bite prevention – avoid mosquito bites by using insect repellent, covering your arms and legs, and using an insecticide-treated mosquito net Check whether you need to take malaria prevention tablets – if you do, make sure you take the right antimalarial tablets at the right dose, and finish the course Diagnosis – seek immediate medical advice if you develop malaria symptoms, as long as up to a year after you return from travelling
Side effects
Like all medicines, doxycycline can cause side effects, although not everyone gets them.
Common side effects These common side effects happen in around 1 in 10 people. Keep taking the medicine, but talk to your doctor or pharmacist if these side effects bother you or don’t go away:
a headache feeling sick or vomiting being sensitive to sunlight Serious side effects Serious side effects are rare and happen in less than 1 in 1,000 people.
Call a doctor straight away if you get:
Bruising or bleeding you can’t explain (including nosebleeds), a sore throat, a high temperature (38C or above) and you feel tired or generally unwell – these can be signs of blood problems.
Severe diarrhoea (perhaps with stomach cramps) that contains blood or mucus, or lasts longer than 4 days ringing or buzzing in your ears
Serious skin reactions or rashes, including irregular, round red patches, peeling, blisters, skin ulcers, or swelling of the skin that looks like burns – these could be signs of a rare reaction to the medicine called Stevens-Johnson Syndrome
Yellow skin or the whites of your eyes go yellow – this could be a sign of liver problems joint or muscle pain that has started since you began taking doxycycline
Headache, vomiting and problems with your vision – these could be signs of pressure around your brain (intracranial hypertension)
A fingernail coming away from its base – this could be a reaction to sunlight called photo-onycholysis
A sore or swollen mouth, lips or tongue
Severe pain in your tummy, with or without bloody diarrhoea, feeling sick and being sick – these can be signs of pancreatitis difficulty or pain when you swallow, a sore throat, acid reflux, a smaller appetite or chest pain which gets worse when you eat – these could be signs of an inflamed food pipe (oesophagitis) or oesophageal ulcer
Serious allergic reactions
Allergic reactions to doxycycline are common and occur in more than 1 in 100 people.
These are not all the side effects of doxycycline.
You can report any suspected side effect to the UK.

Azithromycin (Zithromax) is a macrolide antibiotic used to treat bacterial infections. Zithromax is a semi-synthetic, semi-structural antibiotic with the structural formula of azithromycin. This medication works by inhibiting the growth and reproduction of bacteria in the body. This medication is commonly used to treat the following infections: Acne, Anthrax, Chlamydia, Gonorrhea, Hepatitis B, HIV, Lyme disease, and other sexually transmitted infections (STIs).
Doxycycline and azithromycin are two different antibiotics that have the same chemical structure. Doxycycline is a tetracycline antibiotic that works by stopping the growth of bacteria and preventing them from reproducing. Azithromycin is a macrolide antibiotic that fights bacterial infections. Azithromycin is used to treat a variety of bacterial infections including acne, chlamydia, gonorrhea, and HIV/AIDS.
